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.
