A popular spot for eagles. Why? |
This
week’s
map shows something interesting at the coordinates 41.56 N latitude
and -74.788 W longitude. Take a look at the map to see where this is.
Which eagles show sightings here this winter? Which eagle was here
on 03/21/07?
Let’s explore the area and find out more!
The Mongaup
Bald Eagle Preserve
Many of the eagles in this popular wintering area are resident New
York State birds. (A "resident" bird does not migrate; it stays
in the state all year.)
This is evident by the sky-blue leg band they wear, signifying
them as "New Yorkers." Peter
Nye and his team have banded these birds as nestlings over the years. The
Mongaup area also regularly attracts birds from other states: purple-banded
birds from
Michigan, black-banded birds from Connecticut, and gold-banded birds from
Massachusetts.
Why is this area so attractive to bald eagles?
Let’s take a closer look.
Water from the Mongaup River was dammed up in 1926. The dam generates hydro electricity
that powers parts of NY state. Below the dam in the Swinging Bridge Reservoir
the water is open all year round. Why would that attract eagles?
