Count Birds for Science

Posted on November 3, 2014 by Lesley Arnold

This time of year I start thinking about the birds in my area. The temperatures are dropping close to freezing. I see birds in great flocks swooping into the bird bath and landing on the feeder. Last week there were about 15 Common Grackles splashing and crowding into my bird bath. The winter is upon us here in New Hampshire. The birds need to eat quite a bit of food to keep up their energy for traveling south. Those that stay will need food all winter. I often look out the kitchen window in the winter to see a little black -capped chickadee at the feeder, and I wonder how it can keep warm. The tiny little feet and the skinny little legs look so vulnerable. They need high energy foods and lots of it! I know there are Oak Meadow students that enjoy watching and feeding the birds. If you do also, then you might like to join the Project FeederWatch that is a program of the Cornell University Lab of Orinthology.

“Project FeederWatch is a winter-long survey of birds that visit feeders at backyards, nature centers, community areas, and other locales in North America. FeederWatchers periodically count the birds they see at their feeders from November through early April and send their counts to Project FeederWatch. FeederWatch data help scientists track broadscale movements of winter bird populations and long-term trends in bird distribution and abundance.” Project Overview, FeederWatch.org

Here’s one! The Common Grackle often allows ants to crawl over its body so that they may secrete formic acid, which is thought to kill parasites, a practice called anting. Besides formic acid from ants, the Common Grackle has been observed using various other substances, such as walnut juice, mothballs, lemons, limes, and choke cherries in similar ways.
