I found a hatch-year Mourning Warbler of indeterminate sex at the southwest corner entrance to the Noble Research Center this morning. Fat = a rotund 3.
I found a dead Ruby-throated Hummingbird at the Noble Research Center yesterday and today I found another. Here’s a chance for me to identify, age, and sex this one correctly on the first try.
First things first – northwest alcove.
Okay, other than hummingbird what have we got?
Ruby-throated or Black-chinned? Wings reach tail tip (barely). It’s a Rubythroat.
Hatch-year or older? Bill corrugations? Buffy edges to feathers? Yes on both counts. This is a hatch-year Ruby-throated Hummingbird.
Male or female? The bird is reflecting kind of bronzy-gold rather than just dark green. Female a bit more likely . . .
Tail not notched or forked. That works for female and young male.
Throat spotted or no? Unspotted – more consistent with female.
Shape of p6? A bit more angular than adjacent feather tips but not sharply-swooped. Looks like female wing tip shape.
Does it have a brood patch?
It looks like it might, but it’s likely just another case of apteria similar to the July 22 hummingbird.
So, we appear to have a hatch-year female Ruby-throated Hummingbird, and I’m sad that she, too, met her end so soon after leaving her natal home.
