why no birds?
 

a small 5 acre tract in the east texas has about 1/2 acre cleared, seems
there's never any birds, even when a big bag of bird seed (like home depot
sells) is put out, no birds show up to eat it,,,,,,there are dogs running
loose, would that keep the birds away? (flocks of migrating birds can be
seen flying by sometimes, but they don't land either)
