interesting sandy. i knew the vit k treatment but i didn't realize it was heparin! which leads me to my mystery, though i never would use poison bait. it is all this talk of rats and mice. someone is trying to move into my romeo's sleeping box in the shed. but my reason for posting is quite hilarious- he went to investigate why my 15 some pound bag of composted manure was moving. i am standing at the back door and hear "SQUEEK!" i wish i saw it, but alas i had only my tshirt and undies on and it was still daylight. hey, i work midnights, ok? :) i had a mental picture of it jumping in the air and squeaking at the same time. the big oaf ran out of the shed, belly to the ground, and wanted back in the house. that surprised me. my old man at romeo's age would have had his whiskers twitching in anticipation. so, my mystery continues....though maybe in the process we have discouraged our visitor. i also took the top off his sleeping box to make it less inviting. i have found no rear projectiles. i am also considering leaving the feeders empty for awhile. i would hate to do that. just sharing a story. i didn't want to start a thread just for it. it almost applies.

Ok...so I believe Google helped me ID this as a zebra finch. Looks like it's native to Australia! Must be someone's escaped pet? Wonder how he's doing today? He's a long way from home here in NE FL.

Northern Cardinal would be my guess.
