Crow Show!

19 Feb

crowsThe crows are gathering! You may have noticed that in several places in Berkshire County the crows have been gathering by the thousands! They are not planning a crime scene, its not a ‘omen’, it is more likely a survival technique. When it gets cold they congregate in huge numbers and its called “roosting” just like with chickens. The hypotheses are they do it for warmth, companionship and discussions about where food can be found and as my friend Laurie Brown says, “for sex”. Yes, sex, breeding season for crows in this neck of the woods, according to the folks at Cornell, is in March. There is a hypothesis that they are checking out their potential mates.
Crows have been roosting for as long as there have been crows. What is interesting is that they congregate in some area away from the final roosting site, as pictured here a hundred or so where in the Black Locus trees by the food pantry garden at sunset, spending a lot of time calling, talking, chasing, and fighting, then just before dark then they join the main group for a final roosting spot for the night. Its quite a scene they make. Its wonderful to watch. I sat in my car shivering in the 5 degrees F just to watch this impressive ‘Crow Show’.
