Maps
and Data |
Eagle
habitats are of vital importance for wintering eagles. Conservation
biologists call them essential or critical habitats. Knowing what habitats
these birds use, we can then determine if the areas
are threatened and might be lost. If so, we can work to have
them protected.
We
can now see patterns on the map where the eagles
continue to hold steady. Only one eagle shows movement within her
winter range this week. Take a close look and start seeing like a scientist! |

Getting
to Know You: U27
Let's get
to know bald eagle U27 a little better today. Since her capture in
February 2006 we've mapped her on 2 spring migrations. |
|
Where
does U27 go each winter?
Where will she return
in the spring of 2008? Study the maps of her spring journeys.
Then predict
when she'll head north in 2008. |

Capture
and Release — All on the Same Day! |
|
February
1, 2006 was a big day for eagle U27. On that day she was searching
the icy Delaware River for a meal. She spotted other birds — crows and
immature eagles — feasting on a large dead animal on
the shore and dropped in for a taste. What she quickly found out was Peter
Nye and his team had a net trap all set up to catch her.
Find out what happened to U27, then watch a slow-motion, live action video
of her release.

Question:
Why Move Around on the Wintering Grounds? |
Of
all our eagles, U25 is the most active traveler this winter. In
mid-February U25 crossed the US-Canadian border and once again
headed back south into NY state.
Since Feb. 2 she has traveled north into Canada and then back south
to her current location.
What factors do you think causes this behavior? Make your own
theory:

is necessary for bald eagle survival? Make a list.
- Study these maps for additional clues.

News
From the Scientists |
The
NH Eagles (No Eagles,
Yet!)
"Hi
Journey North!"
"No new words yet about capturing eagles this week. Our
next time period when the rocket net technician and I will
be in NH at the same time is 3/10 thru 3/14. That's when
I'm
hoping we will get the job done!" - Chris Martin

The
NY Eagles
Pete "Eagle-Eye" Nye sends this week's data and then turns
around to head into the field for a week. So far, no large
migratory movements. March is here, though, so stay tuned...! |
