1993 1994 Walter D Koenig Melanerpes formicivorus Change HNHR 21 January 1030. Counted stores: 1242. Tree is quite filled up here. 2 April Lots of stores still here when Erik & I came by to add a feeder. 4 May 1545. No sign of a nest, but lots of acorns and even a bird up in the granary. 5 May 1930. 4 birds here, quite vocally, at roosting. Lots of karrits, pre-roost mounting, interference, and even chasing, but I think they all belong here. Three apparently roosted somewhere across the ravine, while I don't think anyone roosted in the granary - even though they spent all their time there until the last minute. 13 May 830. Checked both holes, which are empty. The top one (at least) is in excellent shape, however. 15 May 945. 23 birds in sycamores. Flew across canyon, then returned to the granary. Still none in either of the holes, however. 1994 19 January 1100. Counted stores: 1557. Tree is pretty much full. Flushed 1 bird upon arrival. 17 April 1430. Checked nest here & measured eggs, of which there are 7. Sizes are: ① 26.5×20.5 ② 24.8×19.1 ③ 27.4×20.4 ④ 24.8×18.7 ⑤ 26.7×20.1 ⑥ 26.9×20.3 ⑦ 25.9×19.1, Stanback had marked the 1st 6; the 7th was new. 20 April 1630. Pulled the eggs for the removal experiment. Eggs put in incubator. 27 April 1315. Plan now is to try and get mate-guarding. To that end, Joey and I are here. Birds over beyond Buckeye Annex...
