Observation details

Continuing. Many photos have been obtained. Overall description shows a yellow-breasted bird with some slight white into the upper breast/throat. Brown upper parts with rufous on the coverts. Black eyestripe with white above and below. Yellow central crown stripe with black crown stripes on either side of yellow crown stripe. Yellow crown stripe not always visible. Age not completely clear but has molted into adult plumage with yellow central crown stripe noted. Based on overall coloration/pattern, there seem to be four to five birds that could possibly be considered as possible species--Great Kiskadee, Lesser Kiskadee, Social Flycatcher, Rusty-margined Flycatcher, and Boat-billed Flycatcher. Bill size and shape seem to rule out all species besides Great Kiskadee. Boat-billed Flycatcher bill is much too large to match the Indiana bird. Rusty-margined has a slightly smaller bill and generally a thicker black eye stripe, although this may be somewhat variable in appearance based on position of the head. Call of the Rusty-margined Flycatcher is a flatter, longer call (especially obvious when comparing spectrograms to that which I've included). Lesser Kiskadee--bill of Lesser Kiskadee should be notably longer in relation to size of the head than the Noble County bird. The Lesser Kiskadee's call is notably raspy and spectrogram is not consistent with my recording. Social Flycatcher is smaller, smaller bill (notably smaller in all photos and guides I can find) and the call is not consistent with the recording I've obtained. Majority of this writeup completed two days after this viewing. Bird viewed mostly through my camera, but also through 10X42 binoculars. Seen with Jeff McCoy, Landon Neumann, Aidan Rominger, Lynn Vernon and another birder I'm unfamiliar with.
