Anatomy of a Food Exchange
I stopped by the bridge this morning on my way to work. It was a decision I'm glad I made, because I had the opportunity to photograph a food exchange between Sabrina and Kaver at close range, as well as some other sights worhty of my time. Already on the Pont de Rennes when I arrived were Jo & Lavanna who were visiting from Ithica; official fledge watchers Roger & Marion, Mr. Bird Nerd Mike, and Brian H. They pointed out one of the juveniles on a low roof of the BeeBee station, fast at work on breakfast:
Nearby sat one of the American Kestels (Falco sparverius), an adult male, I think:
When the fledgling Peregrine moved to the edge of the roof I was able to get a look at her leg band to identify Aura:
After some minutes of inactivity the sounds of hungry fledglings filled the gorge. Looking up, we found Kaver flying in, prey clutched in his talons:
It wasn't long before a fledgling flew into view, and no one was surprised when we identified Sabrina. As she flew nearer, Kaver transferred the prey to his bill:
Sabrina dove behind and beneath her father, then rose toward their rendezvous:
At the last instant Sabrina climbed, talons outstretched, then flipped over as Kaver delivered the meal!
Kacking the whole time, Sabrina flew away with her prize:
She gave us a nice close look as she headed for the catwalk on the High Falls smokestack, where she made a masterful one-footed landing:
While Sabrina ate, we watched the Kestrels flitting around the power station:
Freshly fortified, Sabrina decided it would be fun to chase her sister:
I had to leave for work then, but what a seredipitous detour I'd made!
After dinner I stopped by the Kodak Visitor parking lot where I found a number of watchers assembled. Rhea Mae did quite a bit of flying, looking splendid in the evening light
When she landed on the southwest corner of the 17th floor ledge, Sabrina decided to join her:
There was more flying, but the fading light made it hard to capture. All of the fledglings have shown themselves to be confident flyers, and watching them is made all the more enjoyable knowing that they aren't likely to get into any further trouble.

Wow, Jim! Great shots of the food-exchange and Sabrina's flip to catch it. She really seems to know what she's doing! Thanks for sharing

Great sequence, Jim! Burst mode?
Jim, that food transfer sequence ought to published somewhere. I mean, besides here. It's just perfect, Clear, spectacular, every step there. Also love the kestrel on the rusting windows. They sure know where to sit for greatest effect, don't they? thanks dale
WOW Great shots of aura and sabrina with the food-exchange.I think M&K and their three litlle girls are the best,and so are you!I enjoyed it.Carla
I loved seeing the food transfer so clearly, since I've always wondered exactly how they do it. Thanks for your usual spectacular photos and commentary.
WOW! You really caught Sabrina's flying skills and her "lunch catch" brilliantly, LG. At the risk of repetition, what camera, lens, speeds did you use for this group? Tripod, other "balancing agent", or steady hands?
Thank you so very much for sharing The Joy.
Wow!

Jim, that is the most awesome series of pix. You managed to capture each and every stage of the food exchange. Wow! Huge Kudos to you.
Thanx,

Yep, it was burst mode, Jim. 5 frames/second does wonders for catching the action. I shot it all handheld, Mary, though my lens is image-stabilized. As long as I have good light, I shoot at 1/1000 sec. There's a link on the right side of my main blog page that lists the camera gear I use.
