The long-time feeder hanging in the Callery Pear tree above Sylvan Water lost its home when the tree was cut down this winter. The feeder was moved to a pine nearby. Here are highlights of some ten minutes watching of the rapid-fire action among half a dozen Tufted Titmouses, Three White-breasted Nuthatches, one Red-breasted Nuthatch, and a Black-capped Chickadee.
Why there are always foragers on the ground under a feeder…
Backyard and Beyond 
I’m glad the birds benefit from the feeders. Nutrition must be tough to maintain sometimes.
That could be the feeder at my Ozark cabin. Same birds. (Not sure on the variety of chickadees, though.)
There are always birds on the ground under a feeder because they forage the dropped seed and spilled seed. Mourning doves, White-throated Sparrows, House Sparrows, Fox Sparrows, Dark-eyed Juncos and even the Tufted Titmice make sure very little is wasted. The only time I ever saw a raptor under a feeder is when he picked up lunch, a.k.a. one of the aforementioned species.
