Melanerpes formicivorus
Lower Haystack
Hastings Reservation
8 Jan Start 0945. Granary census on back. √588 + 589 have not been
seen here since October. 1145, cad watch. ♂307 or ♀ 461
Metal/Blu--wht ♀515 Dbn/Yellow ♂587 Metal / Wht-Blk/Bpkr Black
all seen very well indeed. Looks bad for √588 + 589,
although I first thought I got a very quick glimpse of
♂588. In retrospect, I was probably mistaken. Subsequently
I saw the 4 birds several times on different occasions.
Birds aren't coming to the granary much. All 4 were seen
at one time or the other pounding on the bark of the
"Black Bark" Blue Oak on the side of far tortuga facing
the granary. It seemed like they were refurbishing the
sap holes, as opposed to actually drinking sap.
10 Feb Start 1310. I believe I flush four birds out at the
start. Granary census on back. ♀515 Dbn/Yellow, ♂307 Orange R,
♂461 Dblue-wht/LBlue white all show up at granary. Later,
♀587 Wht-Blk/Bpkr-Blk. 1400 ♂307 sapsucking from
Black Bark Blue oak. Complete census, end 1515
♀515 doing a lot of granary work. Perhaps drilling holes?
(5 minor more)
Long periods of pecking at the same storage hole,
17 March Start 1055, granary census on back. Noon, ♀587, ♂307,
♂461 fly across to dry tortuga, drink from a rain well in
a Blue Oak 100-120 m NW of granary. ♂307 then flies
to Sap tree (see 8 Jan) ♀515 did not fly off to drink
with others, remained in granary. 1207, all 4 birds in saptree
1255 end, ♂307, ♂461, ♀515, ♀587 all seen well.
♀515 showing some interest in the double entrance
granary hole. No following of ♀ yet, either
