Melanerpes formicivorus
Arnold 1 Hastings Reservation
20 January Checked the marked acorns, finding 25/30, of which
1 had clearly been moved. I did not search the tree
very thoroughly, however.
17 February 910-930. Watched from a short distance away through the

1025. ♂ is sitting around preening, etc., very much as if she belongs

1036. 2 unbanded ♀♀ landed essentially together in the
