This video from the USA about New York City red-tailed hawks says about itself:
Egg in the nest? Rosie and Bobby switching nest duty – March 15th, 2014
15 mrt. 2014
It appears that there is now, at the very least, one egg in the Washington Square Park Hawk nest.
Bobby and Rosie are now regularly taking turns sitting in their nest. A fellow Hawk-watcher informed me that she saw the nest-switching behavior quite clearly yesterday after I had already left the park for the day.
I took this footage of Bobby and Rosie switching nest duty this morning. Also included in the video is footage of Rosie eating and perching in various spots.
You can hear Rosie calling out starting at the 34 second mark.
I cut the audio in a couple of the clips in order to not distract the viewer from having to hear park noise that was occurring during the action.
At least one of Bobby and Rosie’s eggs have hatched – April 18th, 2014
The first hatching was reported by NYU to have happened yesterday morning (April 17th). The egg hatched three days after it was ‘expected’ to which is so in keeping with Rosie and Bobby’s broods.
Their eggs typically hatch two to three days later than the 28-35 days ornithologists have said Red-tailed Hawks eggs usually do. There are many conditions that affect when the eggs hatch (latitude, for example).
Fledging is said to usually occur 42 – 46 days after hatching but interestingly, all of Rosie and Bobby’s offspring in the past fledged at least two days later than ‘expected’.
If all goes well, this first 2014 hatchling should fledge between May 29th – June 2nd.
