Pine Grosbeaks: Male, Female or Immature?
I got to wondering about all these female Pine Grosbeaks being reported
and whether they might be a combination of mature females and
immature, 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."
Join In On the “Great Backyard Bird Count”
Friday, February 15th through Monday, February 18th
The Great Backyard Bird Count (GBBC) is for everyone, from beginner birdwatchers to experts, and for the first time ever, anyone can participate from anywhere in the world. Counting birds provides scientists and researchers with a real-time snapshot of winter bird populations. Each checklist submitted during the GBBC helps the National Audubon Society, Cornell Lab of Ornithology, and Bird Studies Canada learn more about how birds are doing, and how to protect them and the environment we share.
How to Count the Birds: Easy as 1-2-3!
- Count birds anywhere you like for at least 15 minutes, but longer if you wish. Keep track of the species that you see.
- Make your best estimate of how many birds you saw of each species. For example: 5 Northern Cardinals, 3 American Crows. Huge flocks may be a challenge, but your best guess is still valuable.
- Enter your list online at www.BirdCount.org Put in a new list for each time you count, whether it is on the same day, at the same place, or at a new location.
NOTE: Look for the “Submit your checklists” button on the Great Backyard Bird Count website. You will be able to start entering bird lists at 7:00a.m. Eastern time on the first day of the count, Friday, February 15, 2013.
