Welcome to the 2009 Journey North Bald Eagle Study!

Eagles nest early in the spring and are often caught in winter-like weather >>

Maps and Data

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.

Other 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

03/27/09 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! White Bear Lake, MN

03/24/09 Bald Eagle watchers might be interested to view eagle cam at Sutton Center Bald Eagle Nest website located in Stillwater, OK. One eaglet has hatched--two eggs left. Gutherie, OK (Comments: Great commentary about this year's brooding. Nestcam Website >>)

Maps are 2-dimensional tools we use to represent 3-dimensional space. What does a dot on the map really represent?

Explore a variety of ways to examine a group of eagle sightings. Journey North eagle maps offer interesting details about each satellite transmitted sighting. What bits of information can we learn from other maps?

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.
