955. The hole here now has 6 eggs a couple days incubated.
Probably 2 99 here. Definitely a separate group from the
"upper" canyon here; see their notes for earlier info on this
group.
Note that these 2 groups certainly existed last year as well,
since there were 2 nests here then also.
18 May
1615. Checked the nest here, which now has 5 babies plus 1 egg,
in which there was a hole ~ ½ cm in diameter from which
the contents had been removed; clearly this 6th egg never
hatched.
28 May
1530. Bled the 4 remaining babies.
1630. Well! Wandering down to the lower granary area (by box
115) I discovered yet a 3rd active nest here, with youngish
babies! Hence, I think I'll have to change this group to
"Middle PHF" and make the new 3rd group "LPHF". Heavens!
3 June
There are stores remaining here.
9 June
1130. Oddly enough, only a single baby (#1840) is left in
the hole there. Snake predation maybe? He, at least, was
in OK shape.
