Water oak in my front yard doesn't seem to be producing a lot of acorns. A persimmon tree at my range is doing well, though, and also a pear tree nearby.

Three or so years ago, the mast was prolific. You could hardly walk without sliding out from under the acorns.

I guess it comes and goes. Deer populations are down a bit from what I hear, but birds aren't dependent on mast. I know I've got a healthy population of squirrels around my property, bold squirrels with no fear.
