What's
this eagle waiting for?
(Move your mouse over picture to find out!)
Did you know it takes about 35 days to incubate an egg? The eggs are
about 2.75 inches long by 2.25 inches wide.

Maps
and Data |
Excited
eagle spotters are now reporting in from across the northern latitudes:
"The
raptors are back. Both Golden and Balds arrived right behind the ducks
and geese. The Golden comes in quite close to the house and barn looking
for easy prey." West Danby, NY 03/22/08
Eagles Nesting:
"Verified with photos of two eagles sitting in an old nest
watching the ice fishermen watching them!" Kenora, ON 03/19/08
"I have an eagles nest in my back field. This is the 3rd
year they have used this new nest; we helped them build it by putting
out branches for
them." Dafter, MI 03/23/08
Some of
our NY eagles are still waiting. Maybe the weather just hasn't been
right to give them that push northward. Nothing seems to be holding
back U27 and our Golden eagle R24. Find their location and predict
their next stops when you study this week's maps.
Meanwhile,
more and more people are noticing more raptors moving. How about you?
Keep your own eyes to the skies!

Spotlight: Golden
Eagle Starts Migration North
|
Her
migration has started! Which direction will she go from her location
in northern NY?
Golden eagle R24 is a newcomer to the migration
project (captured
January 18, 2008). How will her path compare with the Bald eagle
migration paths? What do you predict? Stay tuned!
"Eagle-Eye"
Nye and his team were excited to capture her. In all the years
of their work they haven't often have an opportunity to study
Golden eagles and their habits. Read Nye's notes on this work >> |

How
can you tell a Golden Eagle from a Bald Eagle? How
would you answer?
Color:
When mature, the Bald eagle is easily recognizable
by the white head
and tail feathers. A mature Golden eagle is almost entirely
dark brown. It gets its name from a small band of golden-colored
feathers on the top of the wings and the nape. It has a short, dark,
hooked beak with yellow cere.
Immature Bald
Eagles are similar to immature Goldens, but differ in fundemental
aspects of shape. Immature Bald Eagles always have patchy white
underwings and (occasionally) bellies. Golden Eagles have crisp
white patches on the inner primaries and at the base of tail.
Shape:
Golden
Eagles are smaller-headed, smaller-billed and somewhat slimmer-winged
than Bald Eagles and fly with wings held in an upward angle. |

Today's
news is exciting. U27 is really on the move. Take a close look.
Then try measuring how far she has traveled
since leaving her winter roost location at the south end of her range.
