1982 R.L. Mumme
Melanerpes formicivorus
Blom 2
(15 June) As is usual in these cases, we will never know for sure.
Alan watched here on 13 June and saw no feedings, so
the failure must have occurred suddenly between 11 + 13 June.
Also, 13 + 14 June Walter was watching at Corral Viejo
Grande, the group with the huge granary at the mouth of
CU canyon, and he saw ♂718 there on both days, and
apparently a member in good standing! This would strongly
suggest that CU grande is the natal group of ♂717 + ♂718,
which was certainly suggested by my observations of
these birds flying off in that direction while watching roosting
at Blom 2 in Feb + March. Also it suggests that at
least ♂718 is thinking about returning home, if he has not
done so already.
18 June GROUP UPDATE **
① ♀478 disappeared ~ 20 April 1982
Last seen by Alan 15 April. Power-struggle in progress 25 April.
② ♀578 moved here from Road 1 25 April 1982
seen participating (♀ winning) PS here o... 25 April
19 July Strolling by 1000, No activity here. Blom 2 is probably
abandoned. See Alan's notes on Blom 2 and the return
of ♀578 to Road 1.
24 July 1 adult + 3 Banded juveniles here at 1800:
J Blk-rel/Red Yel CPink/M
+ J DPink/Mauve ♂NB
J Or-red/Wht. These are certainly J767, J768,
J769 of Blom 3, with a ♂NB. I flushed all of
them, and all took off toward Blom 3. Thus, it's
pretty clear that Blom 2 is still abandoned.
