All month we’ve been exploring a set of irruptive species: Common Redpoll, Evening Grosbeak, Pine Siskin, and Red-breasted Nuthatch. Let’s take a look at data submitted by citizen scientists like you to Project FeederWatch to see where they are this winter.

    Most years I have been happy to count my birds. This year I have not participated because I have a mean Mocking bird that is chasing all the small ones away. I have had for years a pair of Carolina Wrens that live here year round. Haven’t seen them lately either. I keep putting food out in different places so the Mocking bird can not see all at one time- doesn’t seem to help. We have had an unusual 8″ of snow here in N. AL and still no birds except Mr. Bossy!!! What can I do to get rid of the Mocker? Thank you. JSE
