1976 Walter D. Koenig 5 Melanerpes formicivorus Arnold 1 Hastings Reservation 29 April Watched at dusk. 4 birds zipped into the main storage tree (in another "pack" formation), but then fiddled around for several minutes before they finally settled back into the tree to roost in the hole in the weird limb. 3 May 1700. Set up a mesh trap over the above hole. 4 May 600. Trap worked; unfortunately the birds had apparently roosted across the road. In any case, 6 birds came flying in when activity began. At least one of these, and certainly possibly 2 were subsequently displaced, however. I identified ♀ Red/m #199 in the storage tree; one of the other birds I watched go up near the crown and begin eating some oak flowers. 10 May 2020. At least one bird was roosting in the hole in the storage tree here again. 12 May All 4 birds roosted in the storage tree. An ambush attempt is again called for. 14 May Walking by the storage tree in the late morning a bird was in the roost hole peering out. They may be about to nest, I suspect. 15 May Nobody in the hole during 2 passes of the storage tree. 16 May 1540. Bird in hole on the way down. 20 May 1815. Counted stores: 1050. Nobody in hole last 2 days. 22 May After having set up the trap again last night I thought I'd seen 3 birds go in and a 4th land at the hole and then leave. At 500 I hit and successfully trapped the contents, which turned out to be 2 unbanded 88's (!), both apparently adults with broad patches - leading me to suspect that they see 22 March notes!
