Lower Redrock Lakes

June 20, 1932
This morning we returned to Lower Redrock
Lakes. The swans by the blind left as soon
as we came, and did not incubating until
after 5:00 PM when we left. However, the day
was warm and sunny, and the eggs were
covered. I don't think that any harm was
done by the disturbance. Dr. Coates,
secured still pictures today of the
adults & the young of another family
which Davis and 2 friends caught.
When we chased the family with
4 cygnets one adult took 3, and the
other took 1. Then they separated about
1 mile apart. We took the 3, and left the
one. The adult stayed with the 1 young
for 2 1/2 hours, leaving only once when
it flew away (toward the other adult)
but returned to the cygnet in about
15 minutes. Later we returned the other
3 cygnets to the 1 and left. The adult
from which the 3 were taken did not
return from the place where they had
been taken. I suppose it was looking
for them. Am anxious to ascertain
the results of so much disturbance.
Davis found a swan nest with
2 eggs buried deep. They were ice cold.
Whether these were left after the 4 cygnets
hatched or whether it was a different
nest, we could only surmise. But being
