Melanerpes formicivorus
Black Oak
Hastings Reservation
17 February
1125. Watching. Nobody seen upon arrival.
1130. Found them. Birds are sap sucking in a small Live Oak near
here. (1)♂wn-rei/wn#410. (2)♀red-rt/ree#320. Still here after all!
1202. [illegible]/#102 up in the perch tree. →Wrong! He's ♂red/dg-ra#428!
1215. More birds sap sucking: (4)♂dg/or-wrn#426.
1225. (3)♂wn/yel#102 (now!) over across field a short ways.
1255. 2nd♀ now in sap tree: (6)♀red/m#427.
1310. Birds are also going back into the forest and eating some
oak buds; nobody here has consumed an acorn yet!
1325. Looks good here with ♂? , but my looks and their
visibility (fair to poor while sap sucking) don't warrant a firm
conclusion on ♂321.
1335. Got him! (3)♂reddish - #321. That's it. Leaving.
13 March
1200. Counted stores: central area: 793
Side area: 12 } 805
18 April
1450. Nobody in any known holes here. All dead quiet.
27 April
840. Nobody in any holes. Quite a few (5-6) birds up in the perch
area towards the field, however. So the I've only identified
(1)♀red/m#427, however (plus at least 1 other♀ here).
852.(3)♂wn/yel#102
900. Bad news: there is definitely an ub♀ about 25 ft away from me
eating acorns in the granary. Argh! What's up? (At this
point I have to assume she's an intruder until I see her here
with others or at a nest). Looks like a good time to leave
before somebody else like her shows up.
906. I think I may be ok but that something funny may in fact be going on
with the ♂♂ here - there are too many of them and a little too much activity
