1992 Waltir D. Koenig Melanerpes formicivorus School Hill HNHR (8 May) 1055. ① 8° or ① 385 down along path in tree. 1205. I give up. Can't find anything, really. What is going on here? 12 May 1115. After a couple more roost watches I came up here this morning and finally found the nest - in a Valley Oak way off in the forest down below (~30m) The old SH "C" nest tree. Returning with saws (after pulling off the poison oak- vines growing all over the tree) I opened it to find 4 babies ~5 do. Weights were: 21.1, 20.4, 19.3, and 5.5 gm (latter presumably on the way out). 18 May 1520. Set up an ambush here. Only 3 babies left. 19 May 1350. Set up to catch the ♀. 1445. Nobody feeding! Giving up for now. 23 May 1950. Watched roosting tonight: ① 426 roosted in nest. 24 May 640. Set up to get the ♀. 750. Nothing! Going to have to give up entirely, it would appear, though maybe I can try again later in the morning. 1043. Trying again. 1123. Quitting. This clearly isn't going to work. No point risking the babies. 1 June 1500. Banded & bled the 3 babies; the additional Lewis' looks fine. 30 August 1230. New (fall?) nest in the old forest tree! 3 babies: ① 40.2 gm ② 25.3 g ③ 16.3 g [Est #LED = 11 Aug] 1 September 1100. Babies bled. ① 48.0 g ② 29.9 g ③ 15.0 g < going, going...
