Detalhes da observação
Continuing bird. First found by Greg S. at the end of May. We heard it calling and then it showed at the feeder actively feeding on sunflower seeds. Yellow throat, black mask, lower white eye arc, streaky belly, long bill. Did not have my bins or good camera so only iPhone photos and audio for me. Happy to be in the right place at the right time today… school is officially out and this was a wonderful way to start Summer! According to Aidan Kiley: “This is a very tricky subspecies ID because one study has suggested that the described YTWA subspecies might not be valid due to overlap. However, for eBird purposes, it is not only acceptable, but useful to record a YTWA with a subspecies option, if a bird can be thoroughly documented as showing what we consider to be the field marks for the sub-taxon. In this case, the bird shows an extremely long and thick bill and clear yellow in the lores. This is typical for the Mid Atlantic/Southeastern ssp, dominica. The western-breeding birds (called alibilora) show shorter, narrower bills, and white lores with no more than a tiny touch of yellow. Despite the potential messiness, a Macaulay search will indeed reveal that most SE birds show long bills and yellow lores, and the opposite for birds in the western part of the species’ breeding range. There is certainly some merit to these marks, despite not holding up 100% according to the one study. Yellow-lored, long-billed YTWAs are much less frequent in CT than shorter-billed, white-lored birds, so this is notable.”
