One heard, other seen. Western burbs of Chicago.
- Singing in my backyard, early a.m. - approx 6:30.
High in a locust tree.
Could not see it.
5 note song made of of 2 notes, a fifth apart, starting w/ the C above middle C
C (down to) F, C-C-C.
Imagine a 3 equal part waltz tempo measure.
The first 2 notes took the space of the first 3d of the measure, the C-C-C was the middle 3d, and the rest between phrases the 3d.
So, in equal parts: C F | C-C-C | rest
I’m pretty familiar w/ the local bird song - this was unfamiliar.
There were at least 3 birds answering each other.
Occasionally it would sing the first 2 notes (C F), followed by irregular chirps, but then it would return to the regular pattern.
Not INSISTENTLY repetitive like a (red eyed?) vireo, but definitely somewhat repetitive.
- Seen in local forest preserve, around 8 a.m. - didn’t have my binos or phone.
Small grey bird, flitting between low brush and ground.
“Very flitty” behavior - did not perch anywhere for longer than a second or 2.
Definitely smaller than a robin.
Main color a soft grey like a catbird, but pretty strong darker striping, from the sides of the head down the wings and sides.
Closest I saw in books were Black and White and Blackburnian, but I’ve seen B&Ws before - this was greyer, and less boldly marked.
And not a trace of yellow.The main identifier I saw - which I can’t see in books - was a white “rump” - almost like a yellow-rump, of like a flicker shows when flying away.
Belly was lighter, throat almost white.
