In the absence of natural nesting structures, the hawks
sometimes use man-made sites like this power tower. |
Why
have a nest camera?
To help biologists understand this threatened species by:
- Learning
what prey the hawks are eating
- Examining
why some nests fail
- Determining
how often adults are at nest
- Discovering
why some chicks die

Video
Clips of 2005 Fledglings:
The two young hawks fledged from the nest on June
25 and 26, 2005. They had hatched on May 8 and 11, 2005.
Incubation
Switch
April 29, 2005 |
Ferruginous
hawks incubate their eggs 32-33 days. The female
does most of the incubation while the male hunts
and guards the nest. But as we see in this clip the
male does his share and sits on the eggs now and
then. The female is larger (typical for raptors),
notice the size difference when they make the switch.

It’s
snake for dinner tonight! The nestlings are about
three weeks old.

Exercise
June 16, 2005 |
Young
hawks spend a lot of time flapping their wings to
workout in the nest before they take their first
flight. They need to build up strong breast muscles.
These chicks fledged about ten days after this video
was taken. Look closely and you can see the egg that
failed to hatch in the middle of the nest.

Feeding
Time
June 16, 2005

It’s
a good day! The nestlings are surprised when both
mom and dad bring prey to the nest. The female stays
on the nest while the male makes a quick delivery.
The chicks are about six weeks old and will soon
be ready to leave the nest.
