The Bald Eagle Halia ‘eetus leucocephalus
B.C’s largest raptor. They have a wing span around 6 to 7 feet, can weigh between 5.5 to 13 pounds. They have acute vision, six to seven times better than a human’s. Their main food sources are fish and carrion. A bald eagles life span can exceed 30 years.
It takes five years before they develop the white head and tail feathers.
After the breeding season ends in late July or early August, the Lower Mainland bald eagles migrate north for a few months. They then return in late September or October to their nest sites. Thousands of northern birds also come south, their numbers usually peaking in early December. They congregate on the Harrison River and other nearby salmon spawning streams to feast on salmon carcasses. When the eagle nesting season starts in late January and February, the northern breeders will begin to leave. Over 250 pairs of eagles will remain to nest in the lower Fraser Valley.
Bald eagles mate for life but will find a new mate if one dies.
