Подробности наблюдения
Two well spaced birds, both were exhibiting very active behavior and localized hunting. They were about 1000’ apart, well spaced enough that there is no doubt they were different individuals. Both were easy to stay on and we watched them both separately for 15 or 20 minutes each. The first one was calling and singing, giving diagnostic “pip” calls that are quite different from the “whit” call given by dusky flycatcher. Visually both individuals were identifiable Hammond’s by head shape, which was very angular where it met the bill, and the forecrown sloped to a peak towards the rear of the crown compared to Dusky which is more symmetrical and round with slightly less of an angular meeting at the bill. They both flicked their tails upward and had a grayish vested look with a triangular yellow wash on the belly pointing up into the center of the breast. The first one had less of a notched tail than ideal for Hammond’s, but the head shape was good and ID was unequivocally confirmed by the pip call notes. The second bird had a very deeply notched tail that I believe was outside of the range of variation for dusky. Additionally, the head shape was very strongly diagnostic on that individual and many photos were obtained from different various postures. The second bird was silent, but very cooperative, and there was no doubt of the ID for that one either.
