觀察細節

Possible LEFL or YBFL. Darker upperparts and more compact than nearby ACFL, bill stubbier and darker especially upper mandible, bolder eye ring, short primary projection, occasional “chibek” calls, seemingly in response to occasional incursion / harassment by ACFLs. Frequent tail pumps and wing flicks. Not noticeably yellow. Able to observe very well despite quality of photos. Generally hanging out in woods on opposite side of path in area of feeders. Photos may not be diagnostic, those from rear do give some view of wingtips.
