June 16, 2003 - Not
2, but 3 Osprey Chicks!
|
This is the beginning of the nest survey
operation. The goal is to look into the nest to determine the number
of live chicks, and if there are any unhatched eggs.
In the canoe are
Tracy Marshall, coordinator for this year's Stony Creek hacking program,
Julie Oakes, from the Michigan DNR, and Barb Jensen, OWSEM volunteer and
last year's Kensington Metropark hacking coordinator. They are heading
for C09 and mate's nest on Wildwing Lake.
|
Arriving at the nest platform, the canoe
is held against the platform legs for stability. C09's mate can be seen
flying above her nest, watching the activity, and issuing repeated alarm
calls. C09 was out of camera view, but close by.
|
An observation mirror on a long pole
was used to look into the nest. This is the traditional method for surveying
a nest's contents. Both Julie and Barb could see 3 chicks, and no unhatched
eggs.
|
Within a few minutes of the canoe pulling
away, C09's mate returns to the nest to check on her brood. The chicks are
unharmed, of course,
by this activity.
|
A short time later, C09 arrives back
at the nest too. His mate has her wings spread slightly to shade the
chicks from the sunlight, keeping them cool.
|
After the parents and chicks had time
to recover from the look with the mirror, the canoe heads back to the nest
with a small digital camera atop another pole. Jim Kortge, (in yellow
hat) another OWSEM volunteer, built the setup to photograph the nest's contents.
This was its first use.
|
Sometimes new methods do work as designed!
Here are C09 and mate's chicks. There are indeed 3 of them,
ranging in age from 1 to 2 weeks. The oldest chick is facing right,
the middle chick is facing the camera, and the youngest chick is facing
away. The two older chicks are starting to grow pin feathers, while
the younger chick is only covered with down.
