Swainson’s Warbler is a rare, secretive bird that is tough to get a glimpse of in the wild.
A shy denizen of southern canebrakes, Swainson’s Warbler is more often heard than seen. It spends most of its time on or near the ground in dense cover, walking about in search of insects. Quite plain in appearance, and with a relatively heavy bill, it does not suggest a warbler when it is glimpsed foraging in the undergrowth; however, it may be recognized by its rich musical song, audible from some distance away.
One recently emerged in Central Park, and birders from all over are flocking to see it. Check out the full article to read more about it.
