This page is just for the warblers (family Parulidae of the order Passeriformes).
Though I'm not certain, the blue-grey head on this bird leads me to believe it to be a Nashville Warbler (Vermivora ruficapilla).
These are Yellow Rumped Warblers (Dendroica coronata), by far our most common warbler in the winter. Groups of them hang out in our trees and cheep back and forth to each other. That's when the first photo was taken. As summer approaches they adopt more colorful plumage (as seen in the second photo) and migrate north.
Here is a Yellow Breasted Chat (Icteria virens).
This is a Common Yellowthroat (Geothlypis trichas). It's a shame I couldn't get a better picture, because they're very attractive birds with their yellow throat contrasting with a black face and gray forehead.
These pictures are of Pine Warblers (Dendroica pinus), our most commonly-seen warblers in the summer.
A warbler without any yellow on it at all: a Black-and-White Warbler (Mniotilta varia). I see them foraging a lot on tree trunks, where their plumage blends in well with the tree bark.
It seems that almost all of our warblers have yellow coloration to some extent or another, but this warbler is almost entirely yellow and is simply called the Yellow Warbler (Dendroica petechia). It's a male; the females aren't as bright.
This is a Northern Waterthrush (Parkesia noveboracensis). Despite its name and appearance it isn't a thrush at all, but rather a type of warbler.
This is a Magnolia Warbler (Dendroica magnolia), another Spring-time migrant. It's a shame I couldn't get a better picture; they're very striking birds with the bright yellow bellies and the dark black throat markings.
This is a warbler that I have yet to identify. Probably a female, given the lack of distinguishing markings. Anyone out there have any ideas about what it might be?
Here is another striking yellow-and-black warbler that I wish I had a better photo of. It's a male Hooded Warbler (Wilsonia citrina).
