1983 R.L. Mumme Melanerpes formicivorus Corral Viejo Canyon Hastings Reservation 5 Jan I come over here, 1100, and try to watch OK Corral in the hopes of finding some banded birds. 1200, No such luck. Simultaneously in the granary area I see 5 unbanded ♀♀ and 1 unbanded ♂! Two or more of the ♀♀ look like first year birds (dark eye, short bill). This may be all the birds in the group. 7 April In light of CU#2's incredibly early nest last year, I think it a good idea to walk over here at 1020 and say hello to the holes. Nobody in last years first nest, but in the "holey" Blue Oak above the ganary, I flush a woodpocket out of a "new" hole in a stub on the uphill side of the tree. Wasn't sure which hole, because there were several in the stub, but it bears further watching. 26 April A tour of Corral Viejo groups, 1730-1830, produces the following info. ① Flushed birds out of the 1982 nest holes at both CU#1 + CUGra-de ② Flushed a ♀NB out of the roost hole where we ambushed at OK Corral ③ Nothing at Blom 3 and (surprisingly) CU#2. Will have to check here again to see if we have nests here 28 April Opened the hole at CV Grande (after making a deeper cut) and found 5 Eggs (including 1 partially-buried runt) ~4 days incubation meaning 28 May would be a good landing date. Did not flush anybody out of the hole at CU#1, but I did at OK Corral, meaning that they must certainly have a nest.
