Probably no Overnight Feedings, Plenty of Nest Guarding and Lots of Shading in the Afternoon

Update for Friday, May 17, 2024

My video feeds shut down last night and so I am not sure if there were any feedings between 10:00 PM and 2:30 AM. We predict that nocturnal feeding will slow down and stop altogether as the chicks continue to develop. At 2:30 AM Astrid was on the long perch, standing guard. Most probably she was there for the entire night. A&A are serious about guarding the nest every year but this year they seem particularly vigilant. We believe the threats they are guarding against are primarily falcon intruders – would-be usurpers of the territory, and people on nearby rooftops and in office windows. Another threat to the nestlings is overheating. The parents respond to this by turning themselves into parasols and providing shade during the hottest parts of the day – generally in the mid to late afternoon frame. When it came to shading, both parents took turns and at one point, they were both shading simultaneously. Regarding the nestlings, when they weren’t being shaded or fed, they spent most of their time crashed out on the floor in the back of the box – looking a bit like piles of oddly shaped hunks of cotton wading. When they weren’t doing impressions of stray pieces of insulation, they were hobbling around in the box, flapping their wings, and practicing their squealing calls.

The nestlings continue to develop rapidly. We are now seeing the beginnings of a fringe of wing feathers on the chicks. Their behavior is changing too. They now have better visual abilities. They can peer into the Canyon to veiw their parents’ exciting exploits.  They now react with excitement when a parent flies towards the nestbox. They have also just begun utilizing most of the nest floor – moving around in a more coordinated manner.  As for the floor of the box, it is becoming covered with the feathers of prey. Many of the species the feathers belonged to can be identified. Most obvious are the feathers of a Yellow-billed Cuckoo, Northern Flicker, Virgina Rail, and Blue Jay. Astrid brought in the Virginia Rail in the late morning. Undoubtable, the rail was caught by Ares as he hunted the Mohawk River Floodplain. Astrid had only gotten a few minutes into the rail feeding when she suddenly picked up the food again and left – cackling loudly as she went. We checked around with our PTZ camera, But couldn’t locate any intruder or Astrid and Ares for that matter. Of course, before long they returned to the north face of the State Building, none-the-worse for the adventure.

For most of the day the three nestlings kept to the back corner of the nestbox where they were often invisible to our nest cameras. People looking at or live camera feed were only seeing one chick and sometimes no chicks at all, depending on how closely they were tucked against the back wall. Indeed, they were real corner trolls today. One of the chicks did more walking around than the others today. In fact, it shuffled all the way over to the opposite corner at the back of the box, and it did it while a feeding was underway. The chicks did get fed a lot today. There were a couple of feedings overnight and one especially long feeding in the early morning. That one had to a Pigeon. Astrid spent about 34 minutes stuffing them until their crops resembled balloons on the verge of bursting. The chicks are starting to exercise more today; not just walking, but wing flapping as well.

There were three overnight feedings. There would have been a fourth, but that one would have been a cuckoo. Ares landed on his pillar perch and partially plucked it, but then couldn’t quite bring himself to bring it to Astrid. He knew she would reject it. At least that’s what it seemed like he was thinking. She does famously dislike cuckoos. The meals kept coming during the day with a little lull during the hottest part of the afternoon. At one point during the afternoon Ares brought prey into the box (not a cuckoo). Astrid didn’t rush over to take it from him and so he proceeded to do a feeding on his own. He looked to be doing a competent job. Later on, Astrid brought most of a Pigeon to the box. While she was conducting the feeding, Ares showed up at the nest with still more prey. He tried to get the chicks interested in what he had, but Astrid’s feeding style is difficult to compete with – she’s intense, captivating and impossible to ignore for any chick. I’m afraid Ares was no competition. They didn’t even seem to notice he was there with food, only concentrating on their mother. Ares didn’t stay long and opted to store his food on one of his pantry ledges. Interestingly, despite today’s heat, the falcons didn’t feel the need to shade the chicks in the box. They seem to understand that the nestlings are now capable of making their own way to the shade in the back of the box. After that meal, we heard chirping type alarm calls from Ares in the canyon somewhere. There was an active Peregrine intruder in the territory and he seemed to be dealing with it.  Astrid left the nestbox, stored the leftovers and perched on the steeple – ready to be called into action if needed. Apparently, Ares successfully drove off the intruder and was back on the State Office Building before too long.

The chicks were feeding on a good pasture again today, with Astrid conducting the feedings and Ares providing the prey. Three meals were delivered during the night, and many more throughout the day. Later in the morning, Astrid became irritated by people near the windows of offices adjacent to the nestbox—at least, that’s what seemed to be bothering her. She didn’t go into full defensive mode with prolonged cackle calls, but she did give s single cackle and then spent some time on the roof of the nestbox, glaring at an office window.

In the afternoon, Astrid grew frustrated with the nestlings. They were seeking shade at the back of the box but had separated—two in one corner and one in the middle against the wall. Astrid spent about ten minutes trying to corral them back together into one squirming baby pile.  Despite their resistance and complaining chatters and squeals, she jostled them along and used her wings to scoop and move them. Eventually, she succeeded in getting all three where she wanted them.
