Many thanks for your many questions and comments. It has been wonderful to see these birds beginning to stretch their wings out and gain increasing balance. The next few weeks will be very exciting as these birds prepare to leave the nest. The time from hatching to fledging (first flight) can vary for eagles across their range. For eagles in Maine ten weeks is typically when young birds attempt their first flight. Based on hatch dates of May 7 and 9, I have estimated that these birds could fly as early as July 17th.
Once again the duration of time int he nest can vary. This year has been cool and we have had record amounts of rain. As you might have guessed, this weather does not accelerate growth rates for birds and other wildlife as it often makes food more difficult to find and can slow the rate of growth as birds must use energy for creating heat rather than growing.
No doubt that time will tell as the next weeks pass us by. So enjoy the images and have a wonderful few weeks watching these birds.
All the Best,
