Деталі спостереження
Observed simultaneously as they chased each other at points. Distinct tail dipping. By that I mean, the tail dipped (methodical in nature) and was then brought back up to its resting position. It did not rise above its resting position. This behavior alone pretty much eliminates any other empid. This is opposed to HAFL and DUFL that flick their tail in either direction (usually up first and then down) somewhat erratically. Neither bird flicked its wing, which HAFL and occasionally DUFL perform as well. Both birds had a pale thin and rather concentric eyering, which helps eliminate HAFL and DUFL. Both birds gave a long bodied and in particular a long tailed appearance. This was likely partially in part due to their short primary projection. These latter two features definitely eliminated HAFL and the extreme-ness of the appearance, I would argue eliminates DUFL as well. They were both longer billed than HAFL/DUFL typically appear. Each had a pale lower mandible with a dark tip. Both gave a slightly more liquid whit call than DUFL. Both birds were gray-ish overall and more so than my photos make them appear. I think Audrey's photos capture their overall coloration better. One of the birds had a slightly more green mantle than the other, but neither bird had a trace of yellow on the belly. Could not get a photo of them together.
