Now that we have young visible chicks in one of our nest sites and more soon to hatch on the south side of Morro Rock, I wanted to give you, our readers, something so that you can follow the progression of the young either here at Morro Rock or on the Internet via the many nest cams you may find in the United States, Canada and around the world.
Be sure to click on the images above to enlarge them. This is a series of photographs, from egg to fledgling, and every day between. This series was done in Germany by a renowned woman who has since passed on. Cleve Nash and I both have copies to see how close our observations are, ie: egg laying, first day of incubation, first day of feeding, etc.
Over the years, with these photos and our observations, I would give us a grade of “A-.” Where we always fall short is trying to determine the number of young that will hatch on any given year. At best, it’s a crap shoot. Without seeing into the eyrie, or weighing the amount of food that goes in, forget it!
Today is Tuesday, and I spent five hours watching the nest site and saw three prey items go into the nest. I never saw a chick. Yesterday, I saw two young falcons. Maybe by Friday, I’ll see four!
Happy trails, Bob
Have some fun.
By looking at the photos that we post with our stories, compare the chicks to the progression series of chicks. See what day you think matches the age.
