1981 R.L. Munne Melanerpes fornicivorus Plaque Hastings Reservation 23 Jan Start watch 1110. Light rain by 1150, but F get a complete census ♂473 Green/wht, ♂521 Blk-yellow/m, ♀496 mauve/brt-er ♂494, wht-red/m, ♀606 Bnk-wht/ wht-brkt. 2 March Start watch here 1610. 1705, I actually see a dominance interaction between ♀494 x ♀496. As always, ♀494 was dominant, pecking at the head of ♀496 2-3 times. The two birds were perched in the top stubs of the 2° V0. ♀496 had been there originally, ♀494 approached. ♂473, ♂521 both seen very well as well, but I'm afraid ♀606 is missing. Seems like I should have seen her. 1715, ♀496 tussles with 2 sapsuckers in the locusts by the barn-house. One of the sapsuckers seemed to be chasing the other one as well. End 1720. 8 March Big commotion here at 0800. Lots of warts, waskas, I walk out to find a big chaso going on involving one (or more) School Hill ♀9. The only intruder I saw was ♀602 Blk/ftnt, being chased by ♀494 for sure. Ends quickly, as intruders fly off toward Y. I see ♀496 (although she gave me a scare not showing up for awhile), ♂521, ♂473. ♀606 must certainly be gone. End 0830 18 March I clean out the old nest hole, put in some wood chips, after seeing a bird working in the hole. 24 March A quick watch, 0900-1000. ♂473, ♂521, ♀494, ♀496 all here. 28 March Apananoid watch here. Complete census. Don't look like they're ready to breed yet, although birds checking out the Cabin Blue Oak Hole. Sapsucking from top of trees on Adobe Hill.
