Деталі спостереження
This bird puzzled me, and I left it unidentified in the field. It was later refound and heard and photographed by others, confirming the ID as Ash-throated Flycatcher. Given the very late spring date and coastal location, my mind was wondering about an eastern Brown-crested Flycatcher. The tail pattern in others' photos shows dark extending across at least the outermost rectrix, but the other tail feathers do not show that dark frame. Perhaps the dark frame is abraded away as the tail is quite worn? It's not a particularly big-billed bird either, but eastern BCFL can have quite a bit of variation in bill size, with many looking very similar to ATFL. I'm satisfied with the ID based on the photos of others and the diagnostic calls heard by others. It was silent for me. I tried ATFL playback and it did not respond. I tried BCFL playback and it did respond, coming in briefly to investigate the 'weep' call, allowing me to get these photos. Curious that it responded to BCFL and not to ATFL, but clearly a migrant and not territorial at this site so who knows why it was interested in one and not the other.
