The Return of the Grackles

This has been a very cold and snowy winter but spring is right around the corner. There is nothing better than a walk around the yard looking for the first signs of the crocus pushing up through the sometimes still snow-covered ground. Or cutting forsythia branches to bring inside where the warmth of our home will force the buds into blooms of yellow sunshine. And each year we look forward to the return of the grackles, a sure sign to us that winter is losing its grip.

The dates have fluctuated from the earliest sighting on February 20, 2005 to the latest on March 21, 1999. The temperatures also have ranged from 33 degrees on that same day in February in 2005 (although it had been close to 50 degrees in the days prior) to 68 degrees on March 17, 2003. There have been years where snow still covered the ground.

Everyone may not be as happy to see the grackles as we are. Although primarily ground feeders they will clean out a bird feeder in no time at all if there is still snow cover. Between them and the starlings it can be a chore to keep the suet and feeders full for the other birds that have been feeding all winter. The grackles move into this area as their breeding grounds after wintering just a bit to our south in Pennsylvania and all the way to Florida. They forage and roost in large communal flocks of up to a million individuals and can therefore have a huge impact in an area. Grackles will eat ripening corn as well as corn sprouts and are the #1 threat to the corn crop causing damage in the multimillion dollar range.

Hannah went off to college in 2008 but we still look for the grackles to return and I send her a picture at the first sighting each year.

If you are interested in tracking birds or other species in your area there are a couple of great options. The USA national Phenology Network is an organization that collects such data from researchers, students, and volunteers as a tool to understanding and adapting to variable and changing climates and environments. Please visit their site for more information: USA-NPN. Also, mark your calendars for February 12-15, 2016 for the next Great Backyard Bird Count as another way to help track bird species in your area.
