1991 Waltr D Koenig 1992 Melanerpes formicivorus Road! 7 January 1200. Counted stores: Valley Oak: 350 Sycamore: 920 Elsewhere: 0 } 1270. Not bad, but neither area is close to being full. Capacity is surely in the 3000+ range. 25 March Watched roosting here tonight with Roger. One bird was in the high Sycamore hole early as usual. Two others came by and roosted in entirely different places. Hence, there would definitely appear to be 3 birds here, not the 2 on the field list. Too bad they're all roosting independently! 19 April 1715. Checked the hole from last year, which Mark saw a bird in this morning - empty. 28 April 1330. Mark checked the hole: 4 eggs! 28 May 1800. Banded and bled the 4 babies here and added 2 transplanted Lewis' babies to boot for a final "brood" of 6. 15 July 1620. Out of stores here. 1992 1 January 1000. Counted stores: Valley Oak: 75 Sycamore: 475 } 550 Not very much for these guys. 4 April 1315. Perhaps there are a few lurking here, but for all practical purposes these guys are out of stores here.
