1990 Walther D Koenig Melanerpes forficivorus Prairie Home Field (Upper) HNHR 25 April 900. Bird in hole in upper part of canyon. 915. 5 eggs! 1 a runt. Several days incubated. Possibly both breeder ?f still here? 29 April 1600. Moved a blind up to the nest. On the way down I discovered a bird in another hole over by the more central storage area - another nest? I opened it and it's in good shape but empty. However, a 2nd nest is not unexpected, given that there were 2 simultaneous nests here last year, presumably (Just never confirmed) the product of 2 groups in this area, an upper and a lower group (not sure what Stanback called them last year). 2 May 1010. Bird in hole in the lower hole, but still empty. Also then checked the upper hole, where the babies have just hatched, most likely yesterday. 11 May 955. As of today, this becomes officially "Upper" PHF to distinguish it from "Lower" PHF, where they now have 6 eggs. 15 May 850. Set up to catch birds here. 1040. Finally: a feed, by 8 Or/Red #1713? (sex wrong on list?) Bird is definitely a ? 1104. Yes-its 8 Or/Red #1713. Sex is wrong on field list. He's fed 4 times now. None else as yet. Not much to go on, but offhand I'd say this area is another rare case of "budding". 1200. That's it for now. Hard to tell what's up here: 81713 fed about 20 times in the end but there was little to suggest additional group membership. Surely there is a ?, however? 16 May 1410. Set up again.
