Wednesday, May 23rd

Tonight, Jean and I were joined by another “Owl Tour”. By accident, we and some Robins led the group to the two adult owls in a Red Oak, where the owls had been last night.

They both flew out to the same northern tree as last night, and sang to each other. The songs were in two keys, one for each of them.

They made their way towards the “sex tree” but were chased by Robins much later into the night than usual. At some point the Robins gave up.

(There were Robin alarms from other trees south of the adults. It would be nice to find one of the rehabilitated young ones some night.)

I had a late work meeting, so I could only spend about 30 minutes at the Cathedral. One of the parents was on the Archangel when I arrived, and was soon joined for a few minutes by the other parent. Their backs were turned to me, so it was hard to make a solid identification.

Then one of the eyasses decided to defecate and move around the nest for about five minutes. Other than these two events, the nest was quiet.

Fledge Date Guesses for Manhattan

If you’ve been looking at the Queen’s Hawkcam, you’ll notice that the young are close to fledging. General wisdom is that it take between 42 and 46 days for a hawk to fledge. I’ve tried to take a guess at what I think the Manhattan hatch dates were and calculated the approximate fledge dates. Of course, the normal “Your mileage may vary” disclaimer applies here.

	Eyasses	Hatch (Best Guess)	+42	+46
Queens Nestcam	2	4/13	5/25	5/29
Highbridge	3	4/17	5/29	6/2
Inwood Hill	2	4/20	6/1	6/5
St. John	3	4/27	6/8	6/12
888 7th Avenue	1	4/29	6/10	6/14

One thing I’m sure of however, is that I need to spend this Memorial Day weekend visiting Highbridge and Inwood Hill Park before it’s too late!

Two or Three

The evening started quietly with the mother on the Archangel, and the nest quiet. Then the father came in and did a feeding with food which was already in the nest. Afterwards the eyasses were full of activity, and at one point it looked like we had three babies in the nest. We’ll know for sure in a few days.

Although this looks dignified, the eyasses don’t have much motor control yet and fall down a lot. They’re still at the toddler stage.

Three eyasses are visible. One flapping, one with its back to us behind the hand, and one on the right

Tuesday, May 22nd

On news of the release of the three young owls back into the park, everyone from the core group of owl watchers came to watch the fly out.

It turned out to be an auditory rather than visual evening. The adult owls were not in the Willow this evening. We could hear groups of American Robins, crying in alarm and flying in and out of trees along the west drive.

When the branches were bare, it was easy to search for the owls in the twilight. Now that the trees have leafed out, the trees seem so much darker and dense. So tonight, I didn’t see a single owl perching.

Instead, we hear Robins and Owls. One owl made a soft song for about ten minutes. From this tree, we saw two owls fly out and fly into a tree further north. But the leaves were too dense for me to see anything once they landed again.

Eastern Screech-Owl watching may soon be coming to an end for this season.

Monday, May 21st

I’ve been unable to watch the owls for a week. Tonight, Jean, Chris and I only saw two owls. It’s the right number of weeks for “natal dispersal” to have occurred, so it’s possible that the youngster is now off on its own.

I learned later this evening that the NYC Park Rangers released the three rescued fledglings back into the park near where the nest cavity had been, within an hour of my taking these pictures. Over the next few days, we should learn if the parents accept their young back, ignore them or are hostile to them. It should be an interesting week.
