> I got to wondering about all these female Pine Grosbeaks being reported
>> and whether they might be a combination of mature females and
>> immatures, so went looking for info and found this:
>> "Immature male usually is indistinguishable from immature or adult
>> female until the second year when it molts and grows new reddish
>> feathers. Some young males have some red or orange feathers in the
>> body plumage, which females apparently lack. Females average duller
>> than males (especially on the crown and rump) and have a lighter
>> russet tinge to the head or lighter olive tinge to the breast than
>> males. The color of the head and body is often golden orange or
>> reddish bronze in males, in contrast to golden yellow of the female,
>> and the chin is often buffier or more brown-gray than in the female."
>> So there you are! Anybody who has a chance to study some of these
>> non-adult-male birds and can report how easy these distinctions are to
>> see greatly appreciated!
