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!
