Field Marks and Identifying Characteristics: |
I'll just paste a curated version of what I put into eBird (CHECKLIST
S138081322): At around 8:10 pm, It flew in and landed in Nolan's Siberian elm, where I got my binoculars on it and saw it briefly but well: -- bright rust from top of head to the back and onto the tail -- underside was white with very distinct circular black spots spaced thickly all over the breast as far down as I could see (I could not see the belly) -- face speckled gray [i.e. speckled finely black & white creating a pointillistic gray] with distinct white eyering and a white brow [in retrospect the "brow" was likely the merging of the white lores with the upper portion of the eyering] -- tail short for a thrush, especially noticeable in flight -- thrush bill looked like a robin's bill (not decurved like a thrasher) -- looked smaller than an American robin but bigger than a Catharus thrush (though neither were around for direct comparison) - I ran off to fetch Mark Stackhouse. He arrived and played a recording and the bird answered with three burst of an ethereal but clipped version of what Mark called its song (each time just as Mark played the burble call on Merlin). After a bit, it flew off quickly and low, never to be seen again. Last seen at 2187 South Lincoln Street, heading north. |
Song or call & method of delivery: | RPB (see above) --stupidly, although I had a recording device in my hand, I was too entranced in the moment to deploy it |
Behavior: | Flew very low, about ten feet off ground into a thick portion of a Siberian elm. There it perched for over a minute, allowing me to observe it for about 30-40 seconds. It responded to Mark's Merlin recording of what Mark called the "staccato call" three times, almost instantaneously upon the playing of that call, almost like a duet. After a few minutes, it flew off to the NNW at great speed (i.e. direct fight), again about ten feet off the ground. Never saw it again. |
Habitat: | Suburban back yards with various trees, garden plots, garden sheds, and lawns. My own back yard is a feral, unmowed place. |
Similar
species and
how were they eliminated: |
Brown thrasher eliminated by long tail, dark eye, and shorter bill. Veery eliminated by very distinct, large, black dots on breast; black and white speckling on face around which the rust color wrapped contrastingly; intensity of eyering and white lores; proclivity toward the Wood thrush calls |
Previous
experience with this & similar species: |
According to eBird, I've seen this bird 19 times prior to this one. |
References consulted: | Eventually, looked at National Geographic field guide. |
