1982 R.L. Marone Melanerpes formicivorus Plague 7 June Leslie has been looking for the fledglings the last two days, and has seen only 2 of the 6. I go up to check the nest hole at 1500, and find it empty! So all 6 young must have fledged. 18 June ** GROUP UPDATE ** J722, 724, 725, 726 all not seen after banding 23 May 1982. Very clear now that only J721 + J723 are still around 7 Aug for the last 2 weeks or so, 1 or more fledgling Coopers Hawks have been very conspicuous here. Seems like I hear alarm calls every few minutes. 16Aug Counted stores, 1600: utility pole O 2° g 20 1° g 230 250 TOTAL Also watched off on here, 1500-1700. Complete census, so the coopers hawks haven't done any damage: ♂473, ♂521, ♀494, ♀496, ♂660 Juv dom! plus J721, 723 + 724. Plus I saw 3 dom interactions! J723 pecked twice at J721 and once at J724. Hopefully this will corroborate Leslies hierarchy. Also, I'm pretty sure (not totally positive) that J724 wnt-yellow/whr is molting into ♀ plumage! As J721 + J723 appear ♂-like, they are probably ♂♂. Birds here seen to be doing a bit of supsucking from the burkhouse Live Oak.
