1980 Walter D. Koenig 7 Melanerpes formicivorus Lambert Hastings Reservation 19 October Watched roosting heretnight, seeing 5 birds roost in 3 different holes in this year's nest tree. These birds have also begun to store here. 20 October Watched roosting again, but this time at least 3 birds roosted in the top hole and none roosted in the low hole. I did identify j3 LB-B12/M #582. 22 October 700. At last I ambushed here and came up a winner. I'd seen 2 birds roost in the upper hole (1 a ?) and 1 roost in the low hole; as it turned out the other 2 roosted in the nest hole. The bird by himself in the low hole was j?582; the 2 in the top hole were ?284 and the unbanded adult ?, now ?632, who was the last known unbanded bird in the study area. These 3 (I didn't have an ambush set up at the nest hole) were processed and released by about 645 (the actual ambush took place at 522, when it was still quite dark). At 715 I wandered over to the truck and noted several birds in the area of the old AB nest tree and the large Valley Oak just this side of the canyon. These birds turned out to be the Lambert birds, and I identified ?582 and ?583. (It could still be too early to tell the sex on j?583, however, as ?582 was just molting to a ?). 1 December 1300. Coming up here to count stores, I flushed several birds, 2 of whom I identified as (1) ? CB1 M LB-B12 #582 and (2) ? M/4d-26 #581. Stores: LamFT: 0 ) Old nest tree: 13 {10.22.
