February 6 notes: a visitor!
This bird could be a visitor to Maine or a native. We have identified eagles from as far away as Florida, Michigan, and Saskatchewan spending time in Maine! Nest intruders may be briefly tolerated at this time of year. Territorial adults usually rudely escort them away during the nesting season, even if is an offspring from previous years attempting to visit home. Only once in more than 50,000 observations of nests here in Maine have I witnessed breeding adults allowing a visiting immature eagle to land on an active nest.
Management comments: Non-breeding eagles (especially immatures) often have a nomadic lifestyle for the first few years but tend to return to their natal area as they approach adulthood at 4 - 5 years of age. Immature eagles from Maine have been seen along the Atlantic seaboard from Nova Scotia to South Carolina. Death rates of eagles are higher in their early years due to inexperience and wide-ranging habits. -- Charlie Todd, Maine Dept. of Inland Fisheries and Wildlife
