Day 70, June 30

Orville flew like a real osprey today for the first time. Notice the purple martins flying in formation with him. His weight was 1380g. He started with several 10-foot hops to various perches. He’d been doing this for a few days already. Then he unexpectedly (will I ever learn?) overflew a perch and took off across the lake! He turned towards a finger of the lake that grew narrow between trees, got befuddled in the turn, then clumsily landed in the small branches of an oak overhanging the water. He didn’t make a sound until I drove a boat underneath him.

He eyed the perch and fish, but never came to the boat. I went back to the yard and set up a tripod perch with fish on it. He soon (after many false starts) took off, circled, then set up for a landing in the yard. Just then, our bouncy Australian shepherd exuberantly began running, wagging, and barking in the landing zone.

This, of course, frightened the timid bird who then landed on top of the roof. I was somewhat relieved as I had been in this situation many times. I had the yard set up with several tempting perches and tethered fish. He soon (20 minutes, but it seemed like a long time) flew down to the tripod perch and began eating. I had tempted him to this perch by cutting up some fish with his favorite tin snips in full view.

These birds are not very flexible regarding flying for food or tidbits. At his age, in the wild, an osprey probably should avoid diving at fish he saw swimming under the nest and just let mom safely feed him. Regardless, my bird hesitantly flew down (they also don’t like to get low to their surroundings) to perch. I think the familiar perch is as important as the food at higher weights.

Day 69

Orville flew about 3 feet to the glove several times today at 1326g. I placed the glove over a sturdy perch since he is still clumsy and has trouble balancing on my hand. He nervously ate while perched on my foot as I was standing, but he was quick to hop off if his eating was interrupted.

Day 26

Lots of fish. Catching them, then preparing them for the bird. The first week, I pulled off small pieces with hemostats or tweezers and fed Orville until his crop was full, about a pecan size bulge in his chest. After that, I could cut the fish in pieces and feed him bones and all. He would reject any piece too big or too bony with a very vigorous head shaking, slinging the offensive piece to the side.

He ate vigorously and gained weight daily. He also visibly grew daily. Soon I was using a paper cutter to initial cut the fish, then game scissors to cut the pieces o fail size. He ate the entire fish, entrails and all. I thought there may be some hidden vitamin or biome ingredient hidden somewhere in the fish. I occasionally gave him vitamins for the rare (2 so far) frozen fish I gave him.

He eats a little over one full size bream a day now, 150-200 grams.He has gained from 41 grams to 720 grams in 26 days. When he fills his crop, it gives him about a 10% temporary weight gain.

I am doing a little falconry training already. Hooding him occasionally and briefly and under supervision. I am constantly touching him, especially his talons (although I have not had one that was footy yet) and his beak (they all have pecked badly). I am carrying him around exposing him to everything, all our cats and dogs, cars, outside flying birds, etc.

I am keeping him well fed at all times as I have read this can help with screaming. We shall see.

Hello! I’m Kennonite, a master falconer. I have been experimenting with osprey as falconry birds for several years and have had success in their husbandry and also in catching fish. I am going to use this blog to illustrate my process. Meet Orville, a nestling I obtained the end of April.

This is what he looked like 3 weeks ago. They grow really fast, eating lots of fresh fish.

I am now hooding him occasionally, under supervision. The hood is very loose. I am just trying to expose him to the concept. I also am showing him everything, scratching him, carrying him around a lot. I weigh him daily and feed him 2-3 times a day. He eats all parts of a fresh whole fish, cut into sizes he can swallow.
