That's a cute shot of the Carolina wren teetering on the edge of the trash can, Melanie. You been fermenting any of your seeds? Surprising to hear of a whole flock of them, they're usually just in pairs, or if they have babies, then there will be 3 or 4.
All my birds are used to feeding off the ground as well as the feeders, but most of the seed that falls lands on paving stones, so the seeds are easy to see. Then I have my rebellious brown thrasher who does indeed "thrash" the leaves and mulch on the ground, but it seems he/she enjoys the seed from the feeder and even the suet cakes once in a while. The only ones I never see feeding off the ground are the titmice.
I also have two families of blue jays around now, so there are often 5 or 6 of them out there making a racket. This one thinks he's an owl!
