The Riverside Park pair of Red-tailed Hawk eyasses is really close to fledgling. I wouldn't be surprised if one is off the nest by Memorial Day. Today they did lots of wing flapping and branching. Their tails look a little too short and some feathers haven't grown in on their heads, but otherwise they look pretty close to being ready for their first flights.
The Urban Park rangers have been doing a great job of helping the single parent mother feed the eyasses, by putting out food. I think this made a major difference for the outcome of this nest. The Rangers have also put up posters with simple do's and don't about how to respect the hawks. The posters remind dog owners to keep their dogs on leash.
There aren't enough Urban Park Rangers or Parks Enforcement Police to enforce the leash laws in Riverside Park, so it is helpful if the hawk watching community talks to owners of dogs who have their dogs off leash. This doesn't have to be an adversarial discussion. Last year, the mother would swoop over any loose dog that was chasing squirrels the week before they fledged. So, the issue is not only a hawk safety issue but also a dog safety issue.
