1982 R.L. Munne Melanerpes formicivorus 1500 20 May Watching here again, 0700. Well, no interest in the Lane hole today, but the birds were hanging out a lot near the 1980 nest hole on the side of School Hill. Mate guarding data on reverse. (Complete census (excepting ♀676, who is certainly gone) 23 May Overdue mate guarding watch here, 0800-0930. On 21 May, ~1800 hrs, I was up on the side of Buckeye Hill, and saw 4 birds, 2 of which were ♂677 ad ♂622 What a shocker! It also looked like at least 3 birds were in a "pack" so it seems likely that the males "guarded" ♂601 all the way up there! The birds were on the N side of the chaparal patch, 100 m W of the Buckeye 1979 nest hole. Today, the birds were again hanging around the 1980 nest hole upon School Hill. I never saw the core 3 in the granary area at all, and I got precious little mate-guarding data. Also, the birds are no longer interested in the Log field-Cane hole. However, when Joane checks the Log field gophers by flashlight at night, the last 3 nights she has heard birds harrit from the tree. So they may still be roosting there, and the nighttime disturbance may be why they are not interested in that hole anymore. 27 May I finally make it out here again at 0830, and find ① Mate guarding has stopped, + ② The birds appear to be incubating a clutch in the 1979-1981
