Black-bellied Whistling-Duck Dendrocygna autumnalis

Status and abundance: Rare visitor.

Habitat: Flooded fields, swampy wetlands, shallow lake borders, and large rivers.

Records and remarks: First recorded in 2008. A highly distinctive species with a characteristic call note given in flight (sometimes at night). Has usually occurred in small groups at wetlands near the Mississippi and Ohio Rivers, rarely farther inland.

Fulvous Whistling-Duck Dendrocygna bicolor

Status and abundance: Very rare visitor.

Habitat: Flooded fields, swampy wetlands, shallow lake borders.

Records and remarks: Currently four records of this southern species. Both the 1974 and 2019 Jackson County birds associated with other waterbirds in flooded fields and mudflats near the Big Muddy River. The Jefferson County birds kept to themselves and foraged in shallow water in an agricultural field flooded along the edge of Rend Lake; they were observed from the Nason waterfowl observation deck. The Crab Orchard NWR bird spent much of its time at Heron Flats, a site west of Highway 148 and south of Crab Orchard Lake.

[Bar-headed Goose Anser indicus]

Status and abundance: Hypothetical.

Records and remarks: A probable escape represents the only regional record of this Asian species. Often raised domestically, so the probability that one encountered in the U.S. is an escapee is much greater than the chance it is a true vagrant. Found with other flocks of geese near agricultural fields or reservoirs.

1, Crab Orchard NWR, 22 Dec 1961 (LB)

Snow Goose Chen caerulescens

Mid-November – Late March

Status and abundance: Locally abundant migrant in the west; locally common migrant in the east. Common to abundant winter resident in the west; uncommon to common winter resident in the east.

Habitat: Grazes in large grassy fields and crop fields. Roosts at night on water so most numerous near refuges with large lakes.

Records and remarks: Huge increases in numbers in the last 20 years. Now occurs in the tens to hundreds of thousands during peak passage through the region. One bird tagged during Aug, 1974, on Wrangel Island, Siberia was present at Crab Orchard NWR on 12 Oct 1974 (Frey 1975).

AUTUMN—The first Snow Geese typically arrive during October but the largest numbers occur much later in the season. Departure dates are difficult to discern because so many spend the winter, depending on local conditions.

Ross's Goose Chen rossii

Late November - Late March

Status and abundance: Occasional to locally uncommon migrant and winter resident.

Habitat: Found in large fields, usually near reservoirs and usually with Snow Geese.

Records and remarks: Numbers have increased in the last twenty years, but this small white goose is not nearly as common as Snow Goose. With some searching of large flocks of Snow Geese, it is often possible to find a few Ross’s. Movement patterns closely follow those of Snow Geese, but Ross's Geese seem to arrive a couple weeks later during fall.

Greater White-fronted Goose Anser albifrons

Mid-October – Late March

Status and abundance: Locally common migrant and winter resident. Formerly occasional migrant and rare winter resident.

Habitat: Grassy fields and agricultural areas.

Records and remarks: Numbers have increased dramatically in the last two decades. During peak migration, concentrations in the thousands occur regularly at some of the southwestern refuges. Smaller groups may linger into winter, depending on severity of weather.

AUTUMN—The first migrants tend to arrive around the middle of Oct, but sometimes a few will arrive even earlier. The majority of migrants pass south by late Nov, but some linger later and may attempt to over-winter. Large numbers during Dec may be late migrants.

Brant Branta bernicla

Status and abundance: Very rare visitor.

Habitat: Usually found with other geese grazing in fields.

Records and remarks: This "sea goose" usually associates with other geese. It can blend into a group of Canada Geese remarkably well despite its striking features.

[Barnacle Goose Branta leucopsis ]

Status and abundance: Hypothetical.

Records and remarks: One present at Union Co. CA, 3 Jan 1981 (VK et al.) associated with a flock of Snow Geese. This Old World species is unlikely to occur as a natural vagrant; most North American records are treated as probable escapes from captivity.

Cackling Goose Branta hutchinsii

Mid-November – Mid-March

Status and abundance: Locally uncommon migrant and winter resident.

Habitat: Reservoirs and agricultural areas, including grassy fields and pastures, essentially anywhere Canada Geese are found.

Records and remarks: Known collectively as white-cheeked geese, Cackling and Canada Goose were split into two species after detailed studies revealed assortative mating and genetic differences (Banks et al. 2004). Cackling Geese tend to be the small white-cheeked geese whereas Canada Geese tend to be the larger ones. Body sizes do overlap, however, particularly in subspecies found more regularly in western North America. In southern Illinois, Richardson’s Cackling Goose (B. h. hutchinsii) is about the same size as Mallard, pale breasted, with a small rounded (not oval) head, short neck compared with most Canada Geese, stubby bill and higher pitched call notes. In the 1980s, about 1 in 500 white-cheeked geese identified in southern Illinois were Cackling Geese (Spitzkeit and Tacha 1986). It is unclear if the ratio is similar today. Typically, but not always, associated with large flocks of Canada Geese at Arklands, Baldwin Lake, Rend Lake, Crab Orchard NWR, Horseshoe Lake CA, and Union County CA, but small groups may occur almost anywhere. Greater effort should be devoted to photographing Cackling Geese, making careful counts, and archiving records in eBird. It is possible that more than one subspecies may occur in the region.

AUTUMN—First arrivals usually occur in November, but may appear during October. Weather strongly influences movements of these geese. During mild winters many geese stay north, with few reaching southern Illinois.

WINTER—Highest counts occur on the southwestern refuges and at Rend Lake.

SPRING--Northward movements are affected by weather and may begin during January.

Canada Goose Branta canadensis

Status and abundance: Common migrant and winter resident. Uncommon summer resident.

Habitat: Reservoirs and agricultural areas, including grassy fields, pastures and residential areas near water.

Records and remarks: See Cackling Goose account for notes about identification. Amasses in large flocks at the refuges at Rend Lake, Crab Orchard Lake, Horseshoe Lake, and Union County. Smaller flocks occur throughout the region, especially during migration. Migrant and winter flocks are composed principally of two subspecies: B. c. interior (97%) and B. c. maxima (3%).

AUTUMN—The local breeding population is augmented by migrants arriving during mid- to late fall. Arrival timing and numbers depend to some degree on weather. Numbers have declined over the last twenty years, presumably because more birds are spending winter farther north. Aerial surveys of southern Illinois in the late 1990s routinely counted 200,000 to 400,000 Canada Geese. Numbers now fall between 100,000 and 200,000. Many birds arriving during fall spend all or part of the winter here with only a small percentage migrating south of Illinois. First flocks of fall arrivals normally occur by early October, but peak numbers do not move into the region until December.

513, Rend Lake, 1 Oct 1999 (KM)

WINTER—Highest counts come from aerial surveys made by the IDNR. One of the highest counts was 515,000 in the southern Illinois quota zone during the 1985-86 winter (D. Thornburg). Other counts: 12,000, Crab Orchard NWR, 12 Jan 2015 (JG)

SPRING—Timing of northward migration is influenced by weather and may begin as early as mid-January. Local breeding pairs initiate nesting before the last migrants depart making it difficult sometimes to identify departing migrants.

20,000, Sesser, Franklin Co., 1 Feb 1991 (WDR)

SUMMER--Canada Geese breed commonly throughout the region, a change since 20 years ago when smaller numbers bred locally. Now, breeding Canada Geese are the scourge of golf courses and other recreational sites where they can be rather aggressive and messy. The breeding subspecies is B. c. maxima. Bennett (1957) found 17 nests and 83 young at Crab Orchard Lake between 1949 and 1952.

Mute Swan Cygnus olor

Status and abundance: Rare migrant.

Habitat: Ponds and shallow lakes.

Records and remarks: Occurs most often as a feral species accompanying barnyard geese on farm ponds and at lakes on golf courses and parks. Some individuals appear to be wild birds wandering, perhaps, from locations to our north where they are established breeders. Reports have increased since 2004. Even if it is difficult to ascertain if a bird is wild or escaped, it is useful to report observations to eBird along with details about the situation (at a farm pond, for example, or in a more natural setting).

Trumpeter Swan Cygnus buccinator

Status and abundance: Formerly extirpated. Now a locally uncommon migrant and winter resident. Most reports occur from December through February.

Records and remarks: With the success of reintroduction programs in northern states, migrants and over-wintering birds have begun to occur in southern Illinois again. Numbers have increased since the mid-1990s, particularly since about 2005. Given that both Trumpeter and Tundra Swans now occur in southern Illinois and are superficially quite similar, observers should use caution when identifying swans. Archiving photos in eBird is a good practice.

Formerly a migrant and winter resident, possibly bred. Audubon (1838) recorded Trumpeter Swans along the Ohio River from late October through early March, including a specific record of 2, near Little America, Pulaski Co., 15 November 1820 (Audubon 1929). Spring migrants were seen at Shawneetown, Gallatin Co., 19 March 1885 (Cooke 1888). A summer report included some at the mouth of the Kaskaskia River, Randolph Co., 4 or 5 June 1819 (Peale 1946-1947). Bent (1925) thought Trumpeter Swans outnumbered Tundra Swans in the late 1800s and early 1900s.

Tundra Swan Cygnus columbianus

Late November - Mid-February

Status and abundance: Occasional migrant and winter resident.

Habitat: Shallow water areas of lakes; sometimes roosts on ice with flocks of geese.

Records and remarks: Most migrate north of our region from Canadian and Alaskan breeding grounds to the central Atlantic coast. Generally observed most years in the southwestern counties where they occur at refuges. Fewer records from the eastern counties.

AUTUMN—A few sometimes appear during October, but most early arrivals do not arrive until November or even December. The departure dates of fall migrants is difficult to determine because many birds arriving during fall linger very late into winter.

[Egyptian Goose Alopochen aegyptiaca]

Status and abundance: Hypothetical.

Records and remarks: One bird, 23 Dec 1993-20 Feb 1994, at Union County CA flew well, but was undoubtedly not of wild origin. This is a species of the African tropics. It migrates very little, so the occurrence of a bird in our area by natural vagrancy is highly unlikely. Introduced populations have become established in southern Florida and elsewhere. A small group was present at Baldwin Lake in the early 1990s (DK).

Wood Duck Aix sponsa

Status and abundance: Common migrant and summer resident. Rare to uncommon winter resident.

Habitat: Wooded creeks, flooded bottomland forest, swamps and margins of reservoirs.

Records and remarks: This is the duck most likely to be encountered in forest. Woodies also forage in open water along edges of reservoirs where fairly sizable aggregations may occur, especially during late summer and fall. In flight, their profile is distinctive because of the long, rounded tail. The distinctive call, whoo-eek, is often heard in swamps of southern Illinois.

SPRING—Migration begins as soon as creeks and rivers thaw and continues into April, but departure dates are obscured by the large breeding population. Wood Ducks do not concentrate in large numbers like many other duck species; groups of less than 50 or so birds are commonplace.

6, Union Co. CA, 19 Feb 1989 (TF, J. Hardt, WDR)

SUMMER—Because this species nests in tree cavities, largest breeding populations occur in mature bottomland forests and swamps. Many also breed at lakes where artificial nest boxes have been erected. Nesting begins as early as March and extends into August. Late summer aggregations may include dozens to a few hundred birds in optimal habitat.

AUTUMN—Somewhat larger concentrations are noted during fall than spring. Migrants begin arriving by late September and the majority of birds have passed through by late November. During warm Decembers, many may stay later.

200, Rend Lake, 25 Oct 1975 (BP)

WINTER—Most Wood Ducks leave southern Illinois during winter if lakes freeze, but numbers vary. Christmas Bird Count tallies reach into the hundreds in mild winters but only into the dozens in very cold winters.

Blue-winged Teal Spatula discors

Early March - Mid-May

Early August - Late November

Status and abundance: Common migrant. Rare winter visitor. Rare summer resident.

Habitat: Marshes, mudflats, shallow lakes and ponds.

Records and remarks: This small dabbling duck forms tight flocks while in flight that twist and turn like flying shorebirds. The blue wing patches of males are conspicuous. Males lose their white facial crescent during summer and fall, which can make identification of resting birds somewhat difficult.

SPRING—Arrives later than most dabblers, well after the first spring thaw. Numbers peak during late March and April. Some regularly linger into mid-May.

Northern Shoveler Spatula clypeata

Late August - Early May

Status and abundance: Common migrant. Uncommon winter resident.

Habitat: Marshes and shallow lakes.

Records and remarks: The spoon-shaped bill of shovelers is unmistakable. Males are boldly patterned in green, white, and chestnut when in their breeding colors, but resemble the brown plumage of females at other times. Shovelers have blue-wing patches like Blue-winged Teal, so identification of flying birds should be made with care. Shovelers often forage in social groups where they bunch together and seine the surface of water with their bills, sometimes even spinning in circles like phalaropes.

AUTUMN—Migrants arrive early, with peak numbers passing through from mid-October to mid-November. Some linger each year until freezing lakes force them to fly further south.

Gadwall Mareca strepera

Early October - Early May

Status and abundance: Common migrant. Fairly common winter resident.

Habitat: Ponds, lakes, marshes, and other shallow water areas.

Records and remarks: One of our most beautiful ducks, the male's breeding plumage can be truly appreciated only at close range. It is intricately patterned with black, gray, and white, and has chestnut wing coverts and white secondaries. The white secondary patch is a distinctive fieldmark on flying birds. Gadwalls often associate with other dabbling duck species. They are a common migrant, but flocks generally do not exceed a few hundred individuals in size.

AUTUMN—Migration of a few individuals begins in late summer but is generally not fully underway until late Sep or early Oct.

American Wigeon Mareca americana

Late September - Late April

Status and abundance: Fairly common migrant. Uncommon winter resident.

Habitat: Shallow lakes and ponds.

Records and remarks: Wigeon are usually found in small groups of 2 to 20 birds, although flocks may reach into the hundreds on some occasions, especially during autumn or at prime wintering locations. In flight they are easily recognized by the large white patches on the leading edges of the wings.

AUTUMN—A few arrive during Aug in some years, but a more typical arrival date include late Sep and early Oct. Numbers peak during Nov and Dec, then slowly diminish as winter sets in. Most birds depart for the winter, but many will stay as long as open, shallow water is available.

Mallard Anas platyrhynchos

Status and abundance: Common migrant and winter resident. Uncommon summer resident. Present year-round. Migrants begin arriving by late Sep and leave by late Feb.

Habitat: Ponds, lakes, marshes, rivers, swamps, and flooded bottomland forest.

Records and remarks: The most numerous duck species in the region. Often domesticated, various hybrid forms and varieties can be found in parks and around farms. A Mallard x Northern Pintail hybrid was noted at Crab Orchard NWR, 1 Feb 1986 (SO).

AUTUMN—Detection of fall arrivals is obscured by a breeding population until large flocks of migrants arrive. May occur in huge flocks, especially where extensive shallow water areas exist for resting and foraging. Often forage on waste grains in agricultural fields.

WINTER—Large numbers may be present well into winter, but the majority of birds do not overwinter. The winter population depends on the severity of weather and availability of open water. Nevertheless, Mallards are commonly encountered throughout the entire region in a wide variety of wetland habitats.

SPRING—Migration begins by mid-February and extends into March.

30,000, Franklin Co., 8 Feb 2002 (LS)

SUMMER—Regularly breeds throughout the region at lakes, rivers, farm ponds, even golf courses. Egg-laying begins during March and nesting continues at least through early August.

American Black Duck Anas rubripes

Late September - Early April

Status and abundance: Uncommon migrant and winter resident. Very rare summer resident.

Habitat: Shallow water areas of reservoirs and marshes.

Records and remarks: Usually associated with Mallards, but may form small single-species flocks. Far less numerous than Mallards. Numbers appear to be declining over time. Formerly common, now locally common at times, but generally uncommon. Some individuals show evidence in their plumage of hybridization with Mallards.

AUTUMN—Migration peaks late, usually in Nov and Dec, and extends into early Jan in some years.

Northern Pintail Anas acuta

Late September – Mid-April

Status and abundance: Fairly common migrant. Uncommon winter resident. Very rare summer visitor.

Habitat: Lakes, marshes, flooded fields.

Records and remarks: Graceful, slender ducks that may fly in V-formations when migrating high in the sky. Generally found in shallow water, but migrants may rest in deep water. Sometimes forage on waste corn in harvested fields.

AUTUMN—First fall arrivals may appear in late summer, but it is usually late Sep or early Oct before they become conspicuously present. Fall migration peaks during November and December.

Green-winged Teal Anas crecca

Mid-August - Mid-April

Status and abundance: Fairly common migrant. Uncommon winter resident. Very rare summer visitor.

Habitat: Mudflats and shallow water of lakes and marshes.

Records and remarks: Forms tight flocks in flight, moving quickly and erratically like shorebirds. Often walks on mudflats like shorebirds, too.

AUTUMN—A few early arrivals appear during August and September, but they do not become numerous until October. Numbers peak from mid-October to mid-November. Most have moved south by late December.

Canvasback Aythya valisineria

Early November - Early April

Status and abundance: Fairly common migrant. Uncommon winter resident. Very rare summer visitor.

Habitat: Lakes and rivers.

Records and remarks: Canvasbacks are elegant diving ducks with a distinctive profile formed by their sloping foreheads. They experienced substantial population declines, but have responded well to conservation efforts. High counts during migration are several times larger now than 20 years ago.

AUTUMN—Often form large tightly packed flocks (rafts) in the middle of large lakes where they rest and forage.

Redhead Aythya americana

Late October - Early April

Status and abundance: Fairly common migrant. Rare winter resident. Very rare summer visitor.

Habitat: Lakes and rivers.

Records and remarks: Similar in plumage to the Canvasback, this diver has a very rounded head and two-tone black and gray bill. Small groups may mingle with Canvasbacks and scaup.

AUTUMN—Size of flocks is generally not large during fall migration. First arrivals tend to appear late in the season, usually after 20 October. A few may linger into early January, depending on winter conditions.

Ring-necked Duck Aythya collaris

Early October - Early May

Status and abundance: Common migrant and winter resident. Very rare summer visitor.

Habitat: Ponds, lakes, marshes, swamps, and rivers.

Records and remarks: Occurs in deep, open water of lakes and rivers with other diving ducks, and also shallow areas where stumps and standing trees are present. Frequently visits small ponds, especially those in grassland or pasture.

AUTUMN—Arrives earlier than most other diving duck species. Lingers well into winter when water conditions are favorable. The departure of migrants is difficult to detect due to the presence of wintering birds.

Greater Scaup Aythya marila

Early November - Late March

Status and abundance: Uncommon migrant. Rare winter resident.

Habitat: Large lakes and rivers.

Records and remarks: Sometimes associates with the more common and very similar Lesser Scaup, but it usually gathers independently with its own species. Identification poses challenges unappreciated by many observers. Field guides often over-simplify the differences between Lesser and Greater Scaup. Look for the distinctive rounded head shape with a peak above or just ahead of the eye in Greater Scaup and the white stripe in the flight feathers extending well out into the primaries. Other field marks overlap greatly in the two species, including bill size and head sheen color. Head shape can be misleading on foraging birds because Lesser Scaup with appressed head crown feathers also have a rounded head shape. Greater Scaup are reported nearly every year now, having been absent or overlooked in some past years.

AUTUMN—First arrivals appear with the early November influx of diving ducks. They tend to be present in small, and usually irregular, numbers throughout the fall and winter.

White-winged Scoter Melanitta fusca

Early November - Early December

Status and abundance: Rare migrant.

Habitat: Lakes and large ponds.

Records and remarks: Not detected every year. The bright white patch on the secondaries helps identify this otherwise dark duck in flight, even at a long distance. Like the other two scoter species, White-winged Scoters winter on the ocean coasts and breed at high latitudes, so migration usually takes these birds far north of southern Illinois.

Long-tailed Duck Clangula hyemalis

Early November - Early April

Status and abundance: Rare migrant and winter visitor.

Habitat: Large reservoirs.

Records and remarks: This diving duck sometimes associates with Common Goldeneye flocks, but just as often seems to act independently of any nearby ducks. Most records come from western portions of the region. There is apparently considerable movement even during the middle of winter, so designation of some records to particular seasons can be difficult. Most records are distributed from mid-December to mid-January suggesting that a few birds wander through the region in search of open water ahead of advancing cold weather. May occur annually, but daily checks of the larger reservoirs are probably required to find them each year.

Bufflehead Bucephala albeola

Early November - Mid-April

Status and abundance: Common migrant. Fairly common winter resident.

Habitat: Ponds and lakes.

Records and remarks: Small diving ducks, Bufflehead are usually found in small groups rarely reaching 100 birds. Males have striking black and white plumage with the head having a large white ear patch extending all the way to the back of the head. Males are superficially similar to Hooded Mergansers, but lack the black border to the white head patch, the rusty barring on the sides, and the narrow serrated bill of a merganser.

AUTUMN—First migrants usually arrive during the first few days of November, occasionally earlier. Numbers peak from mid-November to mid-December. Most fall migrants have departed the region by late December, but some regularly linger into winter if conditions are suitable.

Common Goldeneye Bucephala clangula

Mid-November - Early April

Status and abundance: Common migrant and winter resident.

Habitat: Large lakes, ponds, rivers.

Records and remarks: These strikingly patterned diving ducks are highly gregarious. Next to Mallards, they are the most likely duck to occur on a body of water, small or large, during winter. As they fly overhead their wings make a characteristic whirring sound. The males perform a humorous courting display for the females by suddenly extending their neck upward then quickly throwing their head back until it touches the back.

AUTUMN—Arrives late in fall, usually in relatively small numbers at first. Large flocks appear later in winter as northern lakes begin to freeze. Movement occurs all winter.

WINTER—There are only two or three weeks during many winters when the winter goldeneye population appears to be relatively stable. At other times, there are constant arrivals and departures, which can be difficult to ascribe to a particular season.

SPRING—Because many birds stay as far north as possible during the winter, the passage of birds that wintered south of our region peaks very early. As soon as lakes begin thawing goldeneyes move in.

[Barrow's Goldeneye Bucephala islandica]

Status and abundance: Hypothetical.

Records and remarks: Two records from Crab Orchard NWR have been reported: 1 male, 10 Mar 1967; and 1 male, 11 Mar 1957 (George 1968). Although the records are probably correct, no documentary evidence was obtained.

Hooded Merganser Lophodytes cucullatus

Early November - Late March

Status and abundance: Common migrant. Fairly common winter resident. Rare summer resident.

Habitat: Lakes, rivers, swamps, wooded ponds and creeks.

Records and remarks: Generally the merganser that occurs in small flocks, Hooded Mergansers are very common at some localities in southern Illinois, such as Crab Orchard Lake. Outside of the breeding season, they form large, loose flocks while foraging in shallow water for small fish.

AUTUMN—First arrivals typically appear around 1 November, sometimes during the last half of October. Numbers peak during November. Because of the presence of a winter population latest departure of migrants is difficult to assess.

SPRING—Migrants arrive soon after the first thaw. Large groups are not common, because many birds are paired and ready to begin breeding. Some northbound migrants may occur as late as mid-April, but the presence of a breeding population obscures the status of sightings at that season.

SUMMER—Breeding begins early, usually in April, but a nest at Harris Lake, Perry Co., found with 12 eggs on 1 Mar 2012 (Joe Stephens) was initiated in mid-Feb. At least a few pairs may be double-brooded, as indicated by the sighting of a female with 2 yg from a 1st brood and 7 from a 2nd brood at Little Black Slough, Johnson Co., 24 May-7 June 1989 (TF, WDR).

Common Merganser Mergus merganser

Late November - Late March

Status and abundance: Common migrant and winter resident. Very rare summer visitor.

Habitat: Lakes and rivers.

Records and remarks: The most common mid-winter duck, this merganser sometimes packs by the hundreds into the last remaining patch of open water on an otherwise frozen lake. Males have bright red-orange bills and legs, and sometimes have a pinkish tint to the breast feathers. Females resemble female Red-breasted Mergansers, but have a cleaner white throat, bulkier head when viewed in profile, and a clean contrast between the reddish sides of the neck and grayish back and breast.

AUTUMN—Females and immatures arrive earliest, followed very late by males. Peak numbers may not appear until Dec or Jan. May be seen migrating during the day, especially along rivers.

Red-breasted Merganser Mergus serrator

Mid-November - Late April

Status and abundance: Common migrant. Rare winter resident. Very rare summer visitor.

Habitat: Lakes and rivers.

Records and remarks: Closely resembles Common Merganser, but males have a rusty pattern on the chest and grayish sides, whereas females have a more diffuse blending of the rusty hood and gray neck than do female Common Mergansers. Red-breasted Mergansers appear to have a thinner neck and head, a shaggier crest, and a thinner, more straw-like bill because of the narrower base.

AUTUMN—Fall migrants arrive during November in most years. Numbers peak during December, but decline quickly later in December. A few linger into early winter if lakes do not completely freeze.

Ruddy Duck Oxyura jamaicensis

Early October - Mid-April

Status and abundance: Common migrant. Uncommon winter resident. Very rare summer resident.

Habitat: Lakes and marshes.

Records and remarks: The pale cheek patch and stiff, upwardly tilted tail are distinctive fieldmarks of these small diving ducks. Large flocks occur on our bigger lakes where rafts of tightly grouped birds may rest far from shore. Smaller numbers occur on just about any body of water, although they largely avoid rivers.

AUTUMN—Fall arrivals typically follow the first cold front in early October. Numbers peak during Nov and Dec.
