Melanerpes formicivorus
Road 1
14 Nov Start 0930 Lots of storing today, and a solid, complete census, though I was worried about ♂486 (didn't see him the entire first hour) Storing + granary census data on reverse. As expected, ♀♀269 + 383 were the workhorses. End 1130.
17 Nov Start 1115 Storage + granary attendance data on back. complete census here, but a pretty low key day. ♂486 again very scarce. I've notice ♀269 has the habit of opening acorns + storing the cotyledons separately.
End 1315
