The blue-gray gnatcatcher (Polioptila caerulea) is a very small passerine that breeds in deciduous forests and thickets all throughout the US. While a fairly common bird, they are tiny and very erratic in their foraging behavior, and this is the first time I've managed to photograph one this closely. This little fellow was bopping around, feeding and singing on a brisk April morning - a new summer arrival this spring migration. Males are differentiated from females by the quality of the blue sheen as well as the prominence of the black "unibrow".
While superficially similar to flycatchers, gnatcatchers are actually more closely related to wrens, and are part of the superfamily that includes nuthatches and treecreepers.
Captured in Somerset, NJ.
This is such a neat capture. Lucky you, you got this one to sit still long enough. Mine never stopped hopping around (just as you said in your comments) and the auto lens on the camera was constantly confused. (Kinglets are just as bad. They and gnatcatchers feed the same way.)
