• This Week's Migration Data
  (Reported Mar. 8– Mar. 15, 2006):

Happy April! April arrived here in gorgeous fashion, with lots of sun and warm temps; the last week of March was absolutely beautiful here, and as you'll see from this week’s data, eagles seemed to get the urge to boogie also!

Our adults:
U21 continued her move, heading more northwest into Ontario above Lake Superior.
Two birds, U25 and V98 moved north, both now along the St. Lawrence River, I'd say staging for their next moves north. U27 DID NOT move from last weeks fix, what might that mean?
P04 also headed north this past week, now just northwest of Montreal. Unfortunately, the data doesn't tell us exactly what day these birds moved, but you might get an indication if you study the weather patterns (winds) over the week.

Our immatures:
Our two 2004 immatures, Y94 and Y96, have not moved too far, and ditto the four 2005 youngsters; I guess they are doing well and are content where they are!

Well, that's all for this week. We are now busy monitoring all our eagle nests, determining who is incubating eggs and where new nesting pairs are. Within a couple weeks, at most, I would expect all of these adults to be at their breeding territories.

Can you name the Great Lakes seen by U21?

U21 continued her move last week, heading more northwest into Ontario above Lake Superior. Check the map to see how far she flew and note her pathway.
We know eagles have great eyesight. Imagine the view from her migration path.

• How many of the Great Lakes do you think she has been able to see?
• Can you label each Great Lake on our map?
  

Challenge Question #10:
“ Which of our satellite tracked eagles have begun their migrations? List them and note whether male or female. Which birds left the earliest? From this information can you determine whether males or females leave first?”
(*hint: Read capture stories to learn more about each bird.)
