Boundary Bay's 12th Ave Dyke Trail... As part
of The Boundary Bay Regional Park, this section is especially blessed with an abundance of Northern Harriers. There is also a definate presence of Bald Eagles!
Bald Eagles are so named because they are "white-headed". Balde is an Old English term meaning white.
Adult males and females are identical in color... white heads and tails, with blackish-brown bodies. Their feet and beaks are yellow.
Eagles mature at about 4 or 5 years of age, and live to about 30.
With up to a 7-foot wingspan, having a height of 3 to 3 1/2 feet, and weighing 8 to 15 pounds, these great birds of prey can lift about 4 pounds. The female is larger than the male.
An eagle's diet consists primarly of fish, but circumstance can force them to dine on carrion.
These 'eagle-eyed' birds have exemplary eyesight, and are strong swimmers.
Eagle pairs remain together until they are parted by the death of one of them.
Eaglets have all their feathers by 10 to 12 weeks of age. At this time, they are nearly full grown and can make maiden flights from their nest.
Juvenile eagles are a mixture of brown and white, becoming almost solid brown as they progress to adulthood.
Nests (aeries) are usually constructed in tall trees beside rivers or near coastlines.
Bald eagle nests are added to every year. They often become the largest of any bird in North America.
Bald eagles lay from one to three eggs each year, with two being the norm.
Kept warm by both parents alternating incubation duties, eaglets hatch in 35 days.
From the time the parents ready the aerie and the young are on their own (the nesting cycle), takes about 20 weeks.
