1/4 of these (ie, the 20% figure) were current nests.
Therefore it seems most likely that food
is the limiting factor & that the areas differ in
this regard.
Nesting appears to be earlier in areas A+B than in
the south Flambier area.
May 31. Anchutka Island, Alaska
Checked nests with eggs (# 4, 7, 10, 11, 16, 17, 18, 22, 33)
for hatch. Hatch occurred in 7, 10, 11, 16, 17, 18, & 22.
Checked 4 buildings in area 12 (see map under
May 28) (3 quonsets without shelves, 1 frame bldg) and
located one new rosy finch nest (34) in the frame
building, 9 ft up on center rafters of a long
room. Four large young.
Collected 4 Lapland Longspurs (2 ?, 2 ?) from
Makarius Point to see what their reproductive
condition would be. One ? was developing a
brood patch (little vascularity yet & probably not
full size) & the other was not. The former was
diverted and had an active ovary but ova were
not large (2mm was largest). Even so this was
twice the size of those in one examined yesterday.
The other 3 birds were frozen for the present.
Pickled a nestling rosy finch which apparently
fell from Nest 10. I found it dead on the floor,
but in perfect condition. Young Eggs in this nest
had hatched since I last examined it. One nestling was
much smaller than the rest. The dead one was between
