• Field Notes from Peter Nye

The latest map: Look carefully to see all the symbols.

Just a quick update today to give you the latest news from Peter Nye and data for your map. Study the map: Can you find symbols for each of the eagles? Which symbols are for adult, migrating Bald eagles? Which symbols represent the immature birds?

Hi again from U21

Meet U25

Meet U27

Hello Journey North!

We've had a busy few weeks down on our Delaware River. We've been trapping each week, at one or two locations along the 72-mile stretch of the "main stem" we are studying, in order to deploy as many of our radio transmitters as possible this winter. We are employing both conventional (vhf) radios which we have to manually follow after placement, and the more expensive yet efficient satellite transmitters, that once deployed, provide continuous data. Thus far we have deployed 2 vhf radios on 2 immature bald eagles (both females), and 3 satellite radios (PTT's), also all on females.
Here is a short run down on the 3 satellite-tagged eagles we've added this year.

• Bald eagle U21
• Bald eagle U25
• Bald eagle U27

Fortunately, all of our shots have been accurate and successful, including this one. This is not always the case; wind and other issues come up that can throw a monkey wrench into the works, so we feel very lucky. At this point, it appears that all of these birds remain in the general area, and Sarah Shute's job is getting more complicated, as she is the one who is in the area tracking them "on the ground" all winter to monitor their movements and behavior.

Until next week,
