grow with each use. Most of these grew upward in layers
making a taller than usual nest but a few annexed rooms
to the side forming an apartment house, i.e either 2 or 3
old
nest cups in a row. There were 3, triple nests, 2 old double
nests and 2 double nests with one cup currently occupied.
Most nests were in rafters or on shelves safe from rats,
howerver one old nest was located in a sunken (below-ground
level) ledge and another was in a barrel (drum) horizontal on
the ground.
Most old nests were clean, but some contain dung
clear up to the brim & must have been used as winter
roost sites. Three others contained remains of the actual
nest activities. Two contained one buried egg each &
another contained an egg & a small (2 day old) young
bird.
Some buildings contained several old nests or old
nests plus a new nest, but no building contained
two active nests at once.
Each building searched was tabulated as to presence &
absence of old + new nests, presence of suitable nest sites,
and type of building. The data for the area south & west
of South Hanger for May 26 & for the morning of May 27
was tabulated separately from data collected north of
Old Camp on the afternoon of May 27.
The data for s + w. of South Hanger is below:
