Subspecies: rutila
Likely male with the red bill with only the tip black. Female/imm shows more black at least on upper part of the bill. This according to litt. I'm not sure how much variation the female bill can show, but would expect it to show less black in general than what a juvenile does.
Subspecies: rutila
Not sure about age or sex. The overall red bill indicates a male but with the blackish edge almost reaching the base of the bill it could also be a female. Or perhaps a young male with a bill almost transformed to a pure adult male bill. Also see 3089 of same bird the day after.
Subspecies: rutila
Same bird as 3088 it looks. There were many Cinnamons present at the feeders these days, but apparently only this bird chose this perch.
Subspecies: rutila
Slight black along the bill edge suggests a young male. Tentatively, since I'm not sure of the degree of variation within the female bills.
