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.

Explore: U27—How Far, How Fast?

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.
