Melanerpes formicivorus
Pump
(12 April)
Hastings Reservation
900. Back again. ♀ Pub drumming in the storage tree. 1-2 other birds
in the area. Carricks! (Coming from the willows).
910. 888 and ♂ 297 here, also a banded ♀. 8402 still here.
915. Some more Carricks from the willows. Pub in the granary drumming.
925. Someone's Carricked about 12 times back in the willows.
Yes→
(Orlw)
928. Some new birds - an OrLW(?); also a good fight - 2 birds
grasping each other briefly.
1015. Leaving. Action is constantly moderate. Same old birds,
with the 1500 birds stealing some more acorns. Didn't get a look
at the OrLW bird, but was indeed an OrLW!
1435. Back. Action seems to be about as before. 8402 here.
Pub here.
1450. There is a notable lull at the moment - nobody here at all for
the last 10 minutes.
1500. Someone Carricked from the willows. Still no action at the granary.
1502. Pub, ♂ 296, and ♂ 297 now in granary. The ♀ is quite
interested in being friendly; she greets everyone.
1505. ♂ 298 apparently pecked dominantly at Pub, displacing her.
888 here also. Nobody new, however. 1500 birds are definitely
tolerant, if not friendly, to 8402.
1513. Two dominance interactions: ♂ 296 ? Pub; 888 > 297.
1515. Leaving. Except for the ♀, 8402, and the OrLW this
morning, this is not very enlightening thus far.
One thing that's clear is that the old Pump birds are indeed gone:
Purge: 8430, 8432. Former last seen 3 February, latter (last seen 14 March.
(8a 8 present 14 March as well). Both (probably) responded to peanuts
put in on 19 March, but neither was seen on or after
