Birds of Cozumel
Isla Cozumel is host to more than 360 species of birds (see eBird list of species), including a large number of residents as well as non-resident migratory species. Migratory species include both those that are resident during the northern winter and those that pass through on their way to and from their northern breeding grounds. More than 250 different species have been reported on eBird checklists in the past year, and offer an idea of the frequency of sightings.
Endemic Birds of Cozumel Island
Below is an introduction to the species and subspecies that are endemic (including semi- and quasi-endemic) to the island and likely on the target lists of many visiting birders. Information is summarized from Birds of the World (Cornell Lab of Ornithology) and Berlanga et al. (2019); all photos and sound recordings are by Karl.
Cozumel Emerald
(Chlorostilbon forficatus)
Ecosystems: tropical forest, palm thickets, urban
Endemic species and year-round resident
Status: Least Concern
Originally classified as a subspecies for much of the 20th century, this small hummingbird is recognized by its scissor-tail and nearly straight red bill with dark tip; also listen for a dry chatter. This hummingbird regularly on insects and nectar from flowers. Not as common as the Green-breasted Mango, but relatively common in gardens around town, in El Cedral, and on resort properties; also seen in lower and middle strata of mangroves and scrubby woodlands. Especially common around feeders in El Cedral.
Yucatan Woodpecker (Cozumel)
(Melanerpes pygmaeus pygmaeus)
Ecosystems: tropical forest
Endemic subspecies and year-round resident
Status: Least Concern
This relatively unstudied woodpecker is the most common woodpecker on Cozumel; similar to Golden-fronted Woodpecker, but smaller and with shorter bill (approx. half-width of head); note yellow around base of bill and red nape; listen for soft, rolling vocalizations. Seen and heard especially in wooded areas and scrubby coastal areas such as El Cedral, Subdivisión Abandonados, Planta de Tratamiento de Agua, and San Gervasio.
Cozumel Vireo
(Vireo Bairdi)
Ecosystems: tropical forest
Endemic species and year-round resident
Status: Near Threatened due to habitat loss (hurricanes and development)
This relatively unstudied vireo is typically heard and recognized by its vocalizations; reddish-brown upperparts and pronounced white loral patch are distinctive; common calls are a "rapid scolding" that sound similar to the wren; typically forages in lower and middle levels of scrubby woodlands, secondary growth, and thickets in deciduous forests. Reported infrequently from most areas of the island, but especially at Aguadas al Sureste, El Cedral, Subdivisión Abandonados, Planetario de Cha'an Ka'an, Planta de Tratamiento de Agua, and San Gervasio
Rufous-browed Peppershrike (Cozumel)
(Cyclarhis gujanensis insularis)
Ecosystems: tropical forest
Endemic species and year-round resident
Status: Least Concern
The largest vireo on the island, it is heard often and seen regularly; easily recognized by its heavy bill, yellow undersides, and thick reddish eyebrow. Song is distinctive and heard at considerable distance. Common in forested areas and especially along forest edges such as at El Cedral, Subdivisión Abandonados, Planta de Tratamiento de Agua, and San Gervasio
House Wren (Cozumel)
(Troglodytes aedon beani)
Ecosystems: tropical forest, urban
Endemic subspecies; year-round resident and winter migrant
Status: Least Concern
The only wren in Cozumel, it is often seen and heard in open, shrubby woodlands; similar to House Wrens observed elsewhere, with russet mantle and contrasting brownish crown and thin, buff eyering; song and calls are distinct. Commonly observed at: El Cedral, Subdivisión Abandonados, Planta de Tratamiento de Agua, and San Gervasio
Black Catbird
(Melanoptila glabrirostris)
Ecosystems: tropical forest, palm thickets
Endemic species and year-round resident
Status: Near Threatened
The sole member of its genus, the Black Catbird is endemic to the Yucatan Peninsula; apparently separation of a Cozumel population appears unwarranted. Characteristically glossy, uniform bluish black, a long tail and short wings; vocalizations are varied, but distinctly "flute-like". Commonly found in the understorey of deciduous woodland edges. Reported most areas of the island, but especially El Cedral, Subdivisión Abandonados, Planta de Tratamiento de Agua, and San Gervasio.
Blue-gray Gnatcatcher (Cozumel)
(Polioptila caerulea cozumelae)
Ecosystems: tropical forest
Endemic subspecies; year-round resident and winter migrant
Status: Least Concern
Similar to other populations of P. caerulea, but distinguished by darker dorsum; white eyering distinctive; hops and sidles along tips of branches with assistance from wings and frequent tail flicks in search of food; calls are a distinct zeee. Reported from most sites on the island.
Yellow Warbler (Cozumel)
(Setophaga petechia rufivertex)
Ecosystems: tropical forest, mangrove, palm thickets, urban
Endemic subspecies; year-round resident, winter and summer migrant
Status: Least Concern
A subspecies of Petechia Group of Yellow Warbler (Golden), the Cozumel variety of the Yellow Warbler is distinguished from Yellow Warblers of the Northern Group by a well-defined a chestnut crown and chestnut streaking on the breast. Vocalizations are a variant of the typical Yellow Warbler. Regularly seen and heard in a variety of habitats from deciduous forest, to thickets, and coast scrub. Reported from most sites on the island.
Yellow Warbler (Mangrove x Golden)
(Setophaga petechia bryanti x S.p. rufivertex)
Ecosystems: mangroves
Endemic population (?) and year-round resident
Status: unknown
First reported in 2008, this warbler shares characteristics with both the mainland Mangrove (S. p. bryanti) subspecies and the Cozumel endemic Golden (S. p. rufivertex) subspecies (MacKinnon-Haskins and Dzib-Chay, 2017); characterized by a dark chestnut hood and streaking on the breast; typically observed in mangroves or coastal dunes and scrub. Found mainly in areas of mangroves along the northern (Planta de Tratamiento de Agua), western, and southern (Punta Sur) areas of the island.
See MacKinnon-Haskins et al. (2017) for more detailed discussion.
Bananaquit (Cozumel)
(Coereba flaveola caboti)
Ecosystems: tropical forest, palm thickets, urban
Endemic subspecies and year-round resident
Status: Least Concern
Frequently heard and seen along open, shrubby areas and forest edges, the Bananaquit is distinctive with its downcurved bill, bright yellow undersides, dark upperparts, white eyebrow, and white patch at the margin of the flight feathers; a yellow rump is visible in flight. Songs are high-pitched and oscilating, similar to Yellow-faced Grassquit and some insects. Found nearly everywhere, but especially around flowering trees.
Yellow-faced Grassquit (Cozumel)
(Tiaris olivaceus intermedius)
Ecosystems: tropical forest, palm thickets, urban
Endemic subspecies and year-round resident
Status: Least Concern
A small grayish-green finch that is frequently observed in open grassy areas and forest edges; sharp, conical bill; males have distinct bright yellow throat and superciliary; females lack yellow and have more muted facial markings; song is a buzzy trill similar to the Bananaquit, but with more distinct notes. Regular sightings at Aguadas al Sureste, El Cedral, Planta de Tratamiento de Agua, and San Gervasio
Western Spindalis (Cozumel)
(Spindalis zena benedicti)
Ecosystems: tropical forest, palm thickets
Endemic subspecies and year-round resident
Status: Least Concern
Originally considered a tanager, the relationship to other songbirds is unclear. Western Spindalis males are distinct with black and white-stripped heads, reddish-orange to yellow breasts, olive backs, and black and white wings; females are drab brown to olive gray with a white patch at the margin of the outer primaries; vocalizations are high and thin. Feeds mostly on fruits and berries from low shrubs to high trees. Frequently reported from Aguadas al Sureste, El Cedral, Planta de Tratamiento de Agua, Planetario de Cha'an Ka'an, and San Gervasio.

Bright-rumped Attila
(Attila spadiceus cozumelae)
Endemic subspecies and year-round resident
Status: Least Concern
A distinctive and relatively large, but uncommon tyrant-flycatcher on the island. Readily identified by yellow rump, two wingbars, faintly-streaked breast, and stout bill. Heard more often than seen; song is a series of ascending "whee-dip" whistles that descend at the end. Sightings from El Cedral, Subdivisión Abandonados, Planta de Tratamiento de Agua, and San Gervasio.

Cozumel Thrasher
(Toxostoma guttatum)
Endemic subspecies and year-round resident
Status: Critically endangered (last reported sighting in 2006)
Formerly common, but became rare after Hurricane Gilbert in 1988; only a few sightings after Hurricane Roxanne in 1995, and two others in 2005. Similar to the Brown Thrasher of North America, with a long decurved bill, chestnut-brown upperparts, and heavily streaked underparts . Typically inhabited dense, scrubby woodland and deciduous forest.
