It has been nearly a month since I wrote my last blog. On May 6, I made the argument that a Red tail hawk named Big Red should be ‘Mother of the Year 2020.’ I am still entranced with the antics of Big Red, her mate Arthur, and their three eyasses (baby hawks) living on top of an 80 foot light tower at the University of Ithaca. Those fuzzy little nestlings, all cute and bonking one another, are now approaching the ‘fledge’ window.
Fledging is the term used for when the eyasses fly off the natal nest and begin their journey towards being independent of their parents. The average age is approximately forty-two days after hatching for this nest. The eyasses need their flight feathers to have grown in with approximately five but better six dark stripes, not including the white terminal band at the end, in their tail feathers.
They should be able to sleep standing up, and must be able to self-feed. At the time of fledging, the eyasses’ wing span will actually be larger than their parents. The length of the wings will return to a normal size for juvenile hawks during their first molt. The larger wingspan and tail feathers really helps them to achieve success during fledging. They will not get their beautiful red tails until the second year. The ‘fledge window’ for 2020 is between June 4-13. Sometimes a eyass fludges. Fludging is when a chick accidentally flies off the nest. There will be hundreds of eyes on the Cornell Hawk cam as the Js hop, jump, and flap their way to independence.
During the first three to six weeks after fledging, the parents continue to provide food for the young ones while they learn to capture prey on their own, going for ground forays from their perch. They are learning how to control their flight before they can catch things that run away. Their parents will continue to give aerial and soaring demonstrations and help the hawklets well into the end of summer. By the time that Big Red and Arthur are decided which nest of theirs to use for raising their next batch of chicks, the Js will be out finding their own territory. They will not get their beautiful red tail feathers until they are a year old. And, most of the time, they will be two or three before breeding. Arthur seems to be an exception as he was one when he became big Red’s mate.
Big Red has been doing aerial displays for the Js for the past several days. You can tell she is soaring as the Js twist and turn to get a good look at her. Yesterday she flew right up to the nest and pulled up disappearing into the sky as seen in the photograph below. Oh, the little ones so want to fly and soar. It won’t be long!
