More Pine Grosbeaks, Irruptive Species
earlier photos. Pine Grosbeak females and immatures can be either mustard-olive or russet on their plumage. Adult males are rosy red. Other people in our town have Pine Grosbeaks, a friend just said he had 50 at his house.
And while I am writing this, I just looked out the window and saw 18 Common Redpolls, another irruptive species, at our feeders! The careful birder looks closely at the Common Redpolls to see if they can find the more rare, paler, Hoary Redpoll.
The Christmas Bird Counts are coming up (ours is this Sat.), it will be really interesting this year to see what the increase is in the number of irrputive species and where they are occurring in the country.
