Melanerpes formicivorus
Road 3
Hastings Reservation
6 August
1030. I was only able to pick up 8384 in passing by here; also now ♀ Red-Bllk/Red #382.
7 August
815-845. Watched from up on the hill, seeing 8368 and 9265. The birds were primarily over around Pat's Cabin apparently sap-sucking in some live oaks there.
4 September
735. Watching. Several birds around. ① ♀ Yel-Bllk/Yel #383.
② ♀ M/ #269.
800. ③ ♂ M/Bllk-#184. ④ j DB-w/n/or #444. ⑤ j LB-Red/LB #446.
⑥ 8 Dblue #68.
810. 9269 here with a green acorn.
830. ② Bllk-w/n/ Bllk #384 is here hawkings at the creek across from the truck.
904. An ub ♀ intruder quickly chased off, apparently by 368.
905. Leaving. Nothing to speak of as yet.

I've just come across a problem compiling data on this group - contrary to my computer records it's clear from M.H.M. "notes" that he has no idea whether this group bred or not in 1973 or 1974 or really how many birds founded the group in April 1973. Thus I should change the origins of one of each of the 2 "original" ♂ and ♀ here to "Present at" and begin the history here on Sept. 1974.
5 October
① 950. Watching. ① ♀ DB-w/n/ #269. ② ♂ DB'/Or/LB #68
③ ♀ Yel-Dx/Yel #383. Birds have lots of stores - especially chrysolepis.
1005. ④ ♀ DB/Yel-#265. ⑤ ♂ Bllk-w/n/M #384. ⑥ ♂ M/Bllk-w/n #184.
1030. Finally: ① j DB-w/n/or #444. Intruder chased briefly.
1045. Over in the V0 perch tree: j444 and ② j LB-Red/LB #446. These juveniles are certainly steering clear of the storage area.
