|
Eagle |
Began Migration in |
Began Migration in |
| F43 | March 6 | March 12* |
| F81 | March 20 | (No valid data)* |
| K58 | March 3 | Not migrating yet (as of 3/18) |
| K70 | March 11 | March 9 |
| K72 | March 19 | Not migrating yet (as of 3/17) |
| E47 | (New in 2001) | March 14 |
| E49 | (New in 2001) | March 16 |
| E50 | (New in 2001) | Not migrating yet (as of 3/18) |
| E63 | (New in 2001) | March 9 |
*Because Eagles F43 and F81 were captured in Spring 1998 and 1999 respectively, the batteries in their transmitters are now wearing down. Peter Nye had not been receiving reliable readings so we couldn't be sure whether they'd left the wintering grounds yet or not. On March 19th, he received a reliable signal from F43 indicating she had arrived on her nesting territory. Thus, he estimates her departure at March 12th.
