Fledgling Death At Riverside

One of the three fledgling died after being hit by traffic.  The fledgling was found dead with a rat in its tallons, possibly its first kill and may have misjudged flying with the added weight.  The hawk's body was recovered by the Urban Park Rangers, who are sending it to the DOH for testing.

Saturday Reports

I'm in Avignon getting ready to start a bike trip in Provence.  

I got a nice report about Saturday's Riverside activities from Jean Dane.  

"I didn't get there til 6:30, but others reported not much action before that – parents didn't feed all day, 2 still in nest, little explorer still doing a little exploring. Some really spiffy flying-hops while I was there – nice landings – and he likes to balance on that little sharp point that's in the clear.

Right after we packed up to leave, bit after 8: one parent arrived with squirrel, poked around in nest for a minute or so and then flew away again, taking squirrel. Then we had both parents flying circles, perching in nearby trees with squirrel bits and flying away again – "you want it? come get it." It was too dark, starting to rain again, so we left, but it was a nice way to end."

Fledge Day

The brancher, came off the nest for a few hours today.  The time off the nest included some time on the ground.  It then returned to the nest in the mid-afternoon and took a nap!

I suspect the weekend will be full of fun activities.  Please be careful around the fledglings.  I saw many birders get too close to the fledgling.  As calm as a fledgling may look, they’re easily spooked.  Once startled, they don’t have enough experience or flying ability to go to a safe, high spot.  They can easily end up in a bike path or road.

The general precautions include:

  • Giving a new fledgling about 50-100 feet of space.
  • If there is a group of hawk watchers, don’t spread out and surround the bird.
  • Don’t block the “safe exits”.  If you do, you’ll end up moving a bird towards a highway or the water.
  • If someone asks you to move, don’t be stubborn.  Take their advice and if you think they were being overly careful, calmly discuss the issue once you’re away from the bird.
  • Error on the side of caution.  The bird’s welfare is more important than your view or photograph.
  • If you are trying to take a picture with a standard point and shoot camera or a cell phone, you’re too close.

I’m flying off to Paris tonight.  I can’t wait to come back next week and see how our youngsters are doing.  Please feel free to email me your observations while I’m away.

Great Branching Today

The most active of the eyasses wondered around different branches of the nest today.  It was so much fun to watch.  After watching three eyasses in a nest for weeks, it was great to see one exploring the tree.  Fledging can’t be far away.

There has started to be discussion about which eyasses are boys and which are girls around the nest site among the hawk watchers.  At this stage it’s really hard to tell.  Just like 11 and 12 year old girls who are likely to be taller than boys in their class, young male hawks can be bigger that young female hawks while they’re grow up. 

It’s usually a good idea to wait a month or two after fledging to start comparing sizes and begin making guesses about the sex of the fledglings.  The guesses will be just that, guesses.  There is some overlap between size of Red-tails of each sex.  There are big boys and small girls.
