I am a bit disappointed that the other forums on this site are not regularly visited and/or responded to by the heavy weights on this site. Your posting of this question on the ID forum and getting the amount of responses that you are now getting pretty much says something about how this site actually is used by the community.
A comment was made by one of the heavies that I would like to object to a little. I don't want to ruffle any feathers so went to this thread.
My ground feeding suggestion was not regarded as a good idea. Here is my list of ground feeders...
Curve-billed Thrasher, Mourning Dove, Great-tailed Grackle, Gambel's Quail, Mallard, Abert's Towhee, Gila Woodpecker, Eurasian Collared-dove, Cactus Wren, Green-tailed Towhee, White-crowned Sparrow, White-winged Dove, Brown-headed Cowbird, House Finch, Bronzed Cowbird, Inca Dove, House Sparrow, and Ruddy Ground-dove.
I have never seen a Ruddy Ground-dove, a Bronzed Cowbird, and until just recently a Green-tailed Towhee anywhere else but at my ground feeder in my backyard.
I have a lot of activity in my backyard and have not noticed any of these birds scaring away others. What I have observed is that there is a pecking order, with the little ones waiting patiently till the aggressive ones leave.
With the complete absence of birds, I would assume that you want anything to come and visit. I don't know if you are a bird lover or a birder, but if the latter, putting food on the ground will give you an opportunity to see a totally different population than what the hanging feeders will provide. Two other observations, you can put the ground feeder in the opposite corner of your property and cut back on the feeding if you find it not to your liking.
I am up to 53 backyard birds, so my ground feeding hasn't seemed to put a crimp on that number.
