It
is noticeable now; days are lengthening. There's one more hour of light
since mid-February in central NY State. Have you felt the changes where
you
live?
The bald eagles are starting to notice. Migration, like many other
behaviors,
is governed
primarily by changing day length. As days
get longer, a bird's physiology changes, especially their hormone levels.
This in turn stimulates changes in behavior.
What do today's eagle maps tell you? Do you see some change in eagle behavior?

Habits Thanks to satellite radios that can operate for multiple years, we have learned a great deal about our eagles. We have learned where they go in winter. We have tracked their migratory routes, and know their nesting areas. We have also noticed some things about when their migrations start. |

Each year Bald eagle U27 is faithfully the first of our eagles to begin her spring migration. This spring she appears to have started sometime around March 3. Notice the distance she covered by March 7. Early or Late? |

Talon-grappling,
cart-wheeling, and tumbling in mid-air are frequently observed
eagle behaviors. Anyone
who witnesses it says it's the most amazing thing they've ever
seen! Why do they do it?
