My usual backyard pellet gun prey are the Asian collard doves.
Ha ha.
they come in along with the quail, scrub jays, pinyon jays, juncos, etc to eat the scratch I put out for them all. Peanuts for the jays too.
I tell folks those doves are my SHTF emergency food supply.
for now, I'm keeping it to starlings.
but, if I can prove it, a magpie might have to go too. I found an eggshell outside the Gulag extension where I keep a hen that doesn't get along with the others. It was the color she lays, and it's the first in months. I had been out in the wellhouse/reloading room prepping some brass and cracked open the door to check for starlings and spooked a magpie. Up until now, they haven't been on the list, but that might change soon.
