Fasten your seat belts, hawkwatchers - fledge time is near.

Any day now, the eyasses will fledge from the nest.  

           Pamela Dimeler

As with all other milestones, these hawks stick closely to their timeline, and in previous years, it has been right around 47 days from when the third egg hatches to when the first eyass jumps off the nest.

So May 4 was when #3 hatched, and today, June 19, is the 47th day.

I sent John Blakeman some of yesterday's hawk pictures of outstretched wings and close-ups of their head feathers, and asked his opinion on how soon they might fledge.  His response:

"All of these eyasses could jump at any time. There is virtually no down left on the head feathers, and the head feathers have almost completely covered their heads. 

The remnant feather sheaths, anywhere on the birds, are no longer debilitating or consequential; merely artifacts of end-stage feather development. 

But don't be concerned if any of the eyasses (or all of them) elect to stay on the nest for a few more days. One of the Cornell eyasses persisted for many days, when it could have jumped much earlier. There is no way really to predict a jump-off date. The birds have no quantitative compulsion to jump after a typical number of days. Much more stochastic -- chance and random number. 

They all look healthy, alert, and prepared for the airspace they will soon pierce and begin to dominate. 

Give my regards to everyone at FI and the website. Another successful year."      --John Blakeman


The eyasses continue to flap hard and literally spread their wings, and we can see how well developed those feathers now are.

No more feather sheaths are visible.

Most of the wing flapping now is facing forwards to the street, another sign that fledging is imminent.

This is #3, just as ready as its older siblings.

           Pamela Dimeler


As they become more confident, they get closer to the edge... Maalox time!

           Carolyn Sutton


They are jumping vertically higher and higher "catching air"...

                    Pamela Dimeler


... and as with the flapping, are starting to jump sideways...

                Pamela Dimeler


... and ever higher.

          Valerie Russell Hutton


As they jump/flap in and out of the nest from the ledge, they are getting more air time...

           Pamela Dimeler


... and are running out of landing space.

           Pamela Dimeler


It is definitely getting crowded on the nest, and they are not respectful of each other's space.

           Pamela Dimeler


However, when The Boss returns, the body language changes drastically!

          Christopher Ryan


As soon as food becomes part of the equation, though, all decorum is gone.

          Christopher Ryan


If you click on the above image to enlarge it, you can clearly see the difference in eye color between the eyasses (gold) and the formel (dark). The eyes will stay gold for the first two years.

They spend a lot of time out on the ledge now, and the Franklin Institute has now switched over to the ledge camera...

           Tess Cook


... which is positioned outside the Board Room window.

           Pamela Dimeler


This camera lets us see all the action outside of the nest.

                                  Pamela Raitt


Mom and T2 continue to bring food constantly to their ravenous offspring.  Rat remains a favorite...

           Kevin Vaughan


... as well as squirrel.

            Della Micah


But it is quite possible that the two white pigeons in the Family Court flock are no more.  On June 15, dinner was noticeably paler than usual...

            Della Micah


... and it was again a menu item on June 17.

          Christopher Ryan


When they are not eating or sleeping, the eyasses take note of everything in their environment, whether is in on the ground below...

           Pamela Dimeler


... in the air above...

           Pamela Dimeler


... to the  right...

           Pamela Dimeler


... or to the left.

          Valerie Russell Hutton


And all the while, the haggards watch the nest...

          Christopher Ryan


... for anything untoward.  Mom is on the right.

          Christopher Ryan


More often, she is at the tip-top of her favorite tree...

          Christopher Ryan


... while T2 is off hunting.

                Kevin Vaughan


So let's wish these wonderful eyasses a safe fledge and happy landings as they get ready...

           Pamela Dimeler


... to make that first big jump.

                Pamela Dimeler


Let me express my huge appreciation as always for the magnificent photographs from so many hawk followers.   Your images make it a joy to write this blog.

Happy Father's Day to T2


Happy Father's Day to T2!

           Pamela Dimeler


What a privilege it is to share these gorgeous images of T2 and his eyasses from Joe Debold, Pamela Dimeler, and Scott Kemper.

                     Pamela Dimeler


                           Scott Kemper


T2 is the proud parent of this year's beautiful eyasses at the Franklin Institute.

           Pamela Dimeler


Not only was he a miracle last year, helping raise Dad's eyasses, but he has met every challenge of fatherhood this year.

           Pamela Dimeler


Who can forget that amazing moment last spring when T2 arrived at the nest for the first time on May 7, bearing a small furry gift, and with Mom right behind him.  This image was captured by the Franklin Institutes's outside camera that looks down onto the ledge and nest.

           Franklin Institute


Here is T2 making his first ever landing on the nest.  This was an historic moment in hawkdom, as no-one had ever recorded a "floating" tiercel being allowed by a nesting formel anywhere near a nest with hatched eyasses, let alone being allowed to land on the nest.

           Franklin Institute


Here is the same view of T2's first landing as recorded by the more familiar nest cam inside the Board Room window.

           Franklin Institute


Mom grabbed T2's vole (so what's new?) but allowed him to remain on the nest.  This is the first time he saw Dad's eyasses, but from this moment on, he cared for them as if they were his own.

           Franklin Institute


           Franklin Institute


T2 has his own offspring this year, and he has done a superb job of providing for their every need.  All three of his eyasses are healthy and meeting their developmental milestones.

           Joe Debold


They now flap and jump from the nest to the ledge...

           Joe Debold


           Joe Debold


... and back to the nest.

           Joe Debold


           Scott Kemper


The youngest eyass, #3, identifiable by the fluff still on its head, is as strong and active as its siblings...

           Joe Debold


... even though it sometimes has to put up with being "messed with" by an older sib.

           Joe Debold


Though most of the jumping is still facing inwards to the window, each day they jump higher...

           Pamela Dimeler


... and higher.

           Pamela Dimeler


#3 shows some precocity by starting to jump sideways to the window...

           Joe Debold


... as well as facing forwards.  But #3 will have to wait quite a few more days until all the feathers are out of the feather sheaths before those wings will work properly in flight.

           Scott Kemper


The sheathed feathers are clearly visible at the top of these eyasses' wings.

           Joe Debold


           Scott Kemper

Their plumage and coloring changes almost daily, it seems, but #3 has a much darker tail than the other two...

           Della Micah


... who have the more usual brown/black horizontal barring typical of eyasses.

           Della Micah


#3 has barely any barring on its tail.

           Della Micah


So let's salute T2 who flew right into our hearts last spring.

           Scott Kemper


He continues to work tirelessly for his family.

           Scott Kemper


What a magnificent hawk..
