Today’s cold weather has probably prompted the few bird stragglers that didn’t migrate already to hit the skyways fast. But many local species don’t migrate. If you’ve noticed more grackles around Austin, you’re not the only one.
“People do notice them more in the wintertime because that’s when they are in their large communal roosts," Jane Tillman, chair of the Urban Habitat Committee for Travis Audubon, said. "In the summer they spread out and nest, so the males actually have territoriality. But in the winter there’s no breeding going on so everybody gets together in these huge flocks in our H-E-B parking lots."
But just because we may not notice grackles in large flocks year round, doesn’t mean they leave town.
