There
is more action to see on this week's migration map. U25, continuing
to move slowly northward, is just over the international border
in Canada. In fact all the birds are now in Canada. S28 continues
to stay in her location. She more than likely has a nest with one
or more chicks. Take a look at some of the great eagle nest cameras
we have listed this week. You will find it interesting to see what
the adults find to bring for the chick's dinner!
The
past week the birds have stayed put. Is it weather, or whim? You
could check the weather last week to see.

Eagle Sightings Highlights: |
03/24/09
I have been seeing the bald eagle for about three weeks. Today I
got a picture of it on the nest.
The nest is off one of the main branches of Truman Lake just beside
a feeder creek named Little Tebo Creek (see photo R). Roseland,
MO

A week
of warm weather mid-March has melted some of the ice on Bald Eagle
Lake, and we have had bald eagles visiting daily. One day this week
there were 20 eagles at one time sighted fishing along the edge
of the ice and from the trees on shore. Amazing!

Keep
an Eye on the Nest |
March
21, March 22, and March 25 mark the dates the 3 chicks hatched in
the eagle nest at Norfolk Botanical Garden. You can watch some of
the hatching action on their website.
- View
video of all 3 eaglets in the nest >>
From
hatching to fledging the eaglets will be in their nest home for
about 80 days. About what date will they leave home? Cameras will
be covering their progress until then. Stay tuned!
Do
the Math:
Bald eagle eggs generally hatch 35 days after being laid. The 3
eggs were laid Feb. 10, Feb. 13, and Feb. 17. Did they hatch in
35 days?

What
Do You Know: An Eagle Portfolio |
During
the spring eagle study you’re learning just like scientists
learn. You gather information, send in field observations, study maps,
calculate migration distances, and research topics of special interest.
|
Try This!
Gather all you have learned into a 9 X 12 project portfolio. Use your
portfolio to show your observations, life cycle studies, weather information,
maps, research findings, and more. At the end of the season you will
have all your important work all together.
