The Lafarge bald eagle nest in Vancouver, BC has three eggs again this season. The first egg was observed on March 11 and likely laid on the evening of the 10th. The second was seen on March 16, the third noted on March 21st . The exact dates of laying for the second and third eggs are not known. Incubation lasts about 35+ days.
Last year three chicks were reared to fledging at this location, too. While one or two eggs is more common, eagles in an urban environment with a readily available supply of road-kill are producing and raising three chicks more often recently.
The nest is unusual for more than its second season of three eggs, however. It is situated on waterfront property owned by concrete producer Lafarge. Other trees on the property were removed to accommodate the ready-mix concrete facility.
Concerned the lone nesting tree, a cottonwood, would succumb to the elements without the protection of other trees, Lafarge worked with eagle biologist David Hancock to construct an artificial nesting site in November 2009 for the pair to consider using.
They opted for their own nest again this year and so far it seems to have been a good decision.
