Subject: [obol] Speaking of unusual juvenile bird traits
A friend in Canby sent me this shot of an individual juvenile House Finch
frequenting her feeder. Tufting such as this shows up occasionally in
HOFI and is probably a recessive trait in its tendency to linger. The tufts
eventually fall out as more mature feathering takes over. Are there other
such examples in other finches?
