This might be a good day for shorebirds.
In fall, birds migrate in front of cold fronts.
(therefore called wind birds by some birders)
Rain could bring some birds down.

Certainly has increased the activity of the hummers
at the feeders. Saw 10 birds at once for a nothing
suburban yard. (all in the back, was not observing
side or front of house that also have feeders) 
So 10 birds seen at once Xs 4 = 40 birds in the area..?
Whatever the number, sure a lot of dogfights going on.

Even the Monarchs are migrating through.
