Ospreys in Flight

I visited Robb Field On May 16 to see how the Osprey family was doing.  Below is a picture of Mom and two chicks.



I receive a daily email from a birder who shared pictures of one of the Osprey chicks or fledglings flying.  Yesterday, May 20, I went to Robb Field to see what I could see, so to speak.  

The female juvenile Osprey (photo below left) came down to the baseball field.  I believe she was the first born.  A little while later the brother came to visit. (photo below right)  I enjoyed seeing them so close.  I could see that the Mother was watching closely from the nest as they sat on the fence, about 10 feet above the ground.



After the juvenile male arrived, they settled down and just looked around.  Some smaller birds came to visit, but Ospreys eat fish, so they just ignored the other birds.


 A birder who has been watching the Osprey's for a number of years decided that the young'ens had been exposed to the humans long enough.  So, he advised me to get ready to take a picture of them in flight.  Then, I supposed he just clapped the fence to cause them to take flight.  I was so busy concentrating on getting a good picture, I don't actually know what he did.  But, the female immediately took flight.  Not being adept at photographing birds in flight, I barely caught a photo of the female (photo below left).  The male didn't respond as quickly, but when he did, I was able to get the photo on the right.

















As I walked to the Osprey nest, I was buzzed by some Barn Swallows.  Now getting a photo of them with their swift maneuvers was a challenge.

Ospreys




About a month ago, I was walking along the San Diego River in Ocean Beach.  I saw some photographers with very professional equipment taking some photos.  As I passed them, I asked if they had seen unusual birds.  They asked me if I had know about the Osprey nest.  The female photographer showed me where it was.  Of course, the nest rested on the highest light in the middle of Robb Field.  This area is a collection of baseball fields used by the residents and is located along side the San Diego River near where it flows into the Pacific Ocean at Ocean Beach.

The photo below (left) shows that the female left the nest and brought back something to something she seemed to need.  Since the nest is so large, why she did this is a mystery, since they don't usually leave the nest unattended.  I met a photographer who arrived by bike.  As he dismounted, I noticed his camera with a very large lens.  This man gave me some background on the birds.  For the previous two years, the Ospreys had three eggs.  This year there were only two.  The chicks had hatched five days previous to my visit.  Later I wondered how the locals know this, since the nest seems to be about 30 feet off the ground.  This man also advised me that the male does the fishing for food, takes it to his perch about three light poles away.  After the male Osprey has been feasting on the fish for a while, the female begins to call to him and he brings what is left to the nest for her and her chicks.  The man giving me the information, opined that the male is slowly learning.  These birds are monogamous and share responsibility for sitting on the eggs until they hatch.  The photo below on the right shows the mother Osprey sitting on the nest.  The chicks are too small for me to see them.

 On my next visit to the field, I could see the mother in the center of the nest with a chick on each side. (left)  That day, the male was perched about two light stands away. (right)





 On my trip to the field last Tuesday, a man passing me on a bike advised me that the chicks are more active early in the morning.  I choose to check on the Ospreys late in the afternoon.  I expected to see them feeding.  I stood there with nothing happening for about twenty minutes.  Then a few heads popped up.  A man with a camera passing on his bike stopped to ask if I was able to see anything just before the chicks popped up in the nest and came into view.  He told me that a local TV station had covered the Ospreys and said that there were five nests around San Diego Bay. He said that he knew of two, one on Shelter Island and the other nest near Chula Vista.  A short while later, I was able to witness the mother Osprey feeding her chicks from a piece of fish laying on the side of the nest (Photos below)  Unfortunately, I think I stretched the camera to its limits in distance resulting in grainy photos.  The male photographers I've met use a very large lens.  Still, watching her feeding her chicks was a special moment.

I returned to Robb Field yesterday and was able to see one of the chicks trying out its wings.  I saw the chick jumping up and down while trying out it's wings.  It didn't leave the nest though.  Another photographer standing in the field told me that when the chicks are ready to fly, they will move out to the lights beneath them, and then fly to lower light posts near-by.

The mother flew away for a few minutes.  I learned that you can tell it's a female by the coloring around the base of the neck, which looks like a necklace.

I plan to visit Robb Field soon to see if the chicks are ready to fly.
