1987 R.L. Mumme 2 Melanerpes formicivorus LA 2 7 April Start watching here 1330, ♀637 CPK/BTK ♂846 NB plus a 3rd male (presumably ♂611) here. 1345, ♀637 chases out a ♀NB intruder. 1355, ♂611 Blue-wart/Community here too. Good. Weird group still intact. 14 may Watching here 1500 ♂611 CPK/Black here for sure. Probably the third bird, ♂846 NB present as well. They still have a very few acorns remaining in the Blue Oak granary (~35). Doesn't look like ♂(♂?) are tightly packed with ♀. 1600 17 may Start 1115. ♀637 CPK/BTK and at least 1 ♂ here flycatching from the big Valley Oak. ♀637 left alone for a long period, suggest: ① Not ready to nest ② already have Metal/ a nest ③ only 1 ♂ here. 1200, ♀637 and ♂611 Blue-wart/Community here all the time. No evidence of a 3rd bird at least as far as I could tell. Perhaps LA2 is down to a couple. As far as nesting goes ① The back hole currently appears to be occupied by nesting Bluebirds. ② I saw ♂611 and ♀637 take a long hard look at a hole in the top of a broken stub of a Golden Oak near the bottom of South ravine. Fortunately, neither bird went in. Hope they don't nest there. ③ A large Black Oak just west of the previous tree might be worth looking at for hole possibilities. 22 May 1500 These guys have pulled a fast one. After watching here awhile, I see ♀637 fly into the low hole of the granary. I flush her out, climb up to the hole, and find 3 just hatched nestlings and One egg that has a chance of hatching as well. Too bad. Considering
