Here are photos of the "easy" bird.
|bottom left bird|
|wings spread on the left|
|showing undertail coverts|
Note the following:
- pale (AKA hoary) ground color, especially to the back
- less streaking on sides
- rump with minimal streaking
- hairline streaks on undertail coverts
- shorter, "pushed-in" bill
- smaller red "poll"
- tapered outer rectrices indicate a first-year bird
If I have time I'll post photos of a few more interesting redpolls from the same day.
