Melanerpes formicivorus
Lower Arnold 2
Hastings Reservation
(24 October)
1000. Somebody just got chased out of the central area here.
1003. Another intruder brought both, ♂87Or/Maure #122 and ♀8DB/M #123
to the Blue Oak to help chase him off. ♀213 with them (♀121 not here)
1000. Going up to check at UA2. Offhand, unless something
is going on up there, I can't think of any reason not to
have at least ♂8122, 123, +126 be resident here.
6 November Purge:
♂133. Last seen (by P(W) at the Arnold Spring on 18 September
(previously seen here on 22 June) gone for sure by 2 October
→ Disappeared about 25 September ±1 week. Pam described
this bird well (e.g., faded bands) and saw him quite well drinking
from the spring on 18 September; obviously something happened
shortly thereafter, however.
♀215. Last seen flushing from the nest on 13 May, gone
most likely at that time or by 22 June → Disappeared
about 31 May ±2 weeks. Though no good censuses
were made, this bird, with her wing-streamer, was notably absent
after the nest failure here.
Add:
♂122. Moved here as adult about 25 September.
Others (♂8121,123,126) await one more check of the area.
14 November
940. Watching.
942. (♂PLP/DB-wh(u)) #213, in Blue Oak. Just sitting.
1006. ♀back with a ♂ right-legged ♂#122. Seen later: ♂Or/Maure 122,
1000. (♀8DB/wr) #126. 1023. (♀DB/M) #123.
1032♂8 DB-well(u) M #121. All here. Now for a final check up at
UA2 (birds are still flying up ♂ in that direction).
