This is the second day that I've observed the Bald Eagle pair perched in the same tree that they were in yesterday at the other end of the property. I first saw them yesterday at 12:30 p.m., and they stayed until shortly before 6:00 p.m. Today, they flew from the distant tree to one closer to the house with much calling and communication. There they settled for a brief time only before one of them flew off.
"Perching Habitat"
"...eagles consistently use certain trees and even certain branches on the tree. As much as 75 - 83% of the daylight hours may be spent on a perch. Most perches border open areas and provide a good view of the surrounding habitat. Exposure to the sun may also be important by helping to reduce heat loss." source: Status on the Bald Eagle in British Columbia, February 1994 (Wildlife Branch, Ministry of Environment, Land and Parks, Victoria, B.C.)
