A Couple of Cool Live Webcams

An Eagle's nest!
The live video feed is streamed online 24/7. At night an infrared light provides night vision to viewers through the cam. Infrared light is not visible to eagles; they do not see it or know it is there.
Some info. on the eagles in the nest shown:

How high is the nest?
About 80 feet.

How big is the nest?
about 6 feet across, about 4 feet deep; it weighs about 1000 lb.

How old is the nest?
The eagles built it in 2007. A previous nest close by fell when a windstorm broke one of the branches.

Are these eagles banded?
No.

Which is the male and which is the female?
It is hard to tell the difference unless they are both on the nest. The female is larger than the male. This female has a ridge above her eyes that goes further back than on the male, and her eyes are surrounded by a greyish shadow; the male has a line around his eyes that makes them look “beadier.” Some think that the male’s head is “sleeker” than the female’s.

What is the history of this pair?
They have been together since the winter of 2007-2008. Her markings at that time indicated that she was about 4 years old. They successfully hatched and fledged 2 eaglets in 2008, then 3 in 2009, and 3 more in 2010.

When were the eggs laid in 2010, and when did they hatch?
First egg was February 25, second on February 28, third on March 5. First hatch was April 3, second on April 6, third on April 9. All three eaglets fledged and are now on the wing but are not being tracked.


And, now, from large to small...

A Hummingbird's nest!

Very cool!!
