Watching the 927 Fifth Avenue Red-tailed Hawk Nest
The last successful nest at 927 Fifth Avenue was in 2018, when Pale Male and Octavia had two eyasses (hawk chicks). Octavia laid eggs the next year and brooded but the eggs didn’t hatch. There was another failed nest in 2010.
Since it’s been awhile and I suspect there will be many new hawk watchers, young and old, I thought it would be a good time to go through how to watch this nest and how things progress throughout the spring and summer.
I made some slides about Pale Male in 2019 and what to expect to see over a year while watching him. Pale Male is no longer with us, but the slides give you a sense of what to expect this year. This video from 2017 shows the stages of development of eyasses on a nest.
On May 8th, the first feeding was spotted by birders and on May 16 a birder first saw what seems to be this year’s only eyass pop up its head for the first time. Generally, the eyasses fledge (leave the nest) somewhere between 42-46 days after they hatch. Roughly, that puts the fledge date somewhere between June 19th and June 23rd, although we’ve seen eyasses wait longer, sometimes up to 50 days to leave. Young hawks have individual personalities and we see some precocious eyasses fledge early (sometimes too early), and some who just want to stay on the nest and get fed by their parents.
Eyasses grow to full size before they fledge, so we’re going to see this year’s hatchling quickly grow up. That’s good, because it’s really hard to see this year’s eyass now. Generally, it’s been hugging the wall of the building. If you view the cradle and think of it as a clock, it’s generally around 11 o’clock. The best view of it is from a twenty feet north of the canopy of 944 Fifth Avenue, a few blocks north of nest building. But this is far enough away that a spotting scope is really necessary to get a good view.
It will become much easier to watch them with binoculars by the end of May. Soon the eyass will be getting much bigger, but still generally white, and then go through an awkward stage as downy feathers are replace by its flight feathers.
I encourage anyone who hasn’t watched a Red-tailed Hawk nest to do so this year. It’s incredibly enjoyable. The “hawk bench”, where the best viewing is from, is just next to the Hans Christian Andersen statue on the west side of the Model Boat Pond.
