Dave's looking at.....





Birds... bald eagles. It was low tide yesterday. There were at least 10 that we could see sitting here at the marina.

Color - Both male and female adult bald eagles have a blackish-brown back and breast; a white head, neck, and tail; and yellow feet and beak.
Juvenile bald eagles are a mixture of brown and white; with a black beak in young birds. The adult plumage develops when they are sexually mature. It takes about five years for their head and tail feathers to gradually turn white.
The bald eagle is the only eagle confined to North America. There are no other large blackish-brown birds with a white head and tail in North American .

Size - A female bald eagle's body length varies from 35 to 37 inches; with a wingspan of 79 to 90 inches. The smaller male bald eagle has a body length of 30 to 34 inches; with a wingspan ranging from 72 to 85 inches. An eagle's average weight is ten to fourteen pounds. Northern birds are significantly larger than their southern relatives.

Remember...you can double click the photo's to make them bigger.
