They're back (again)

Last year, the first grackles materialized on March 13th; this year, several of them were at the tray feeder on February 20th. I'm not sure if this means that they exhausted their regular food supply earlier (which wouldn't surprise me, given the harshness of the winter) or if they were celebrating a break in the weather.  I'm inclined to suspect the latter, as one of the males has already started his female-attracting behavior: fluffing out his handsome feathers and pointing his pointy beak straight up at the sky.  Ah, love.
