and therefore not encouraging other visitors to
the park to trespass. We set up a mist net over
shaft #5 and the double width net over the larger
shaft uphill from 5. While setting up the latter, 2
rosy finches arrived (1:30pm) & one of these dove into
the shaft even though Marr & I stood at the edge of
the hole (one on either side) holding the net. The bird
was immediately caught in the net. We finished
near 2:30 pm
setting up the net & left, prior to the return of
any additional birds. Mist nets over both holes
had been lowered so that they were out of sight in
the shadows of the shafts.
While rosy finches were returning to the above
holes, we collected birds at 2 other shafts (#4 & the
hole to the north) using shotguns. We each collected 6
birds, including one littoralis & one atrata. Many other
birds appeared at the shafts but they would rarely
land where they could be retrieved after shooting. The
birds usually dove into the shafts without hesitation
or caution. They did this even when I stood at the
edge of the hole. Rocks thrown into the hole would
usually cause a few birds to fly out, often landing on
the wall of the shaft just below the top. In such a
location they could investigate the disturbance & [illegible]
also remain out of the wind. We continued to note
the high musical notes made by the rosy finch which
contrast with the harsher chirps so frequent in summer.
