Hummingbird 2
Long day 16 1/2 made nest, 18 outside.
Nest fastened by twigs to ceiling
At 12:30 a.m. went into upper tunnel. A ground tyrant flew; caught him. Then a streaked spine tail flew,
body temp. warm. Then a hummer flew but escaped. Then another hummer flew; caught him. Then caught a
torpid hummer. It was hanging from the ceiling, actually
hanging from a vertical fixture, using tal to help support
herself. Temp of tunnel here, 25 feet from entrance,
was 14, temp. of bird in gullet 14 1/2. Kept her alive
until next morning when she was normally active.
Photographed her.
In the lower tunnel at 12:30 caught 1 acture hummer
(may have been the one that escaped upper tunnel) whose
gullet temp. was 36. Tunnel 14.
In afternoon found another tunnel nearby. This
one too had the remains of a nest, about 20 ft in.
After travelling over into the soft valley south, at (1,200'
also, we looked in another tunnel and found remains of
another hummer nest. Hence of 4 tunnels that we had
looked in, each had a single nest. Of the 5 hummers
we caught in 2 tunnels, all were 4.
Dec.15 Rio Santa Rosa, 13,300ft. Anty saw a hummer come out of
a flake-like hole in a stream bank.
