Day # 32 of incubation was a cold one in the falcon’s Downtown Canyon. Temperatures were in the low 30s in the early morning and barely reached 40 degrees in the afternoon. There were even a few snow showers and strong wind gusts. Understandably Astrid stayed very tight to the eggs through most of the morning. She adjusted them often and gradually moved the entire clutch all the way to the back northwest corner of the box. We presume because it was warmer there? Ares first showed up at 5:27 AM, but she sent him away. He showed up again at 5:55 and she threw him out again. With no switches taking place, we had no way of knowing if any of the eggs had pips in them. At 8:36 she gave an alarm call, which launched Ares into action. No intruder was seen, but it is conceivable that there was one. At 10:41 AM, Ares came back to the box and Astrid finally let him take over incubating. It was during this changeover that Deb saw that egg # 1 (the egg that was laid on April 1st) had a large pip in it. It was even a big enough hole to see the chick moving around inside. By 11:25, lots of calling was being heard from the chick in the breached egg. A little later when Ares was adjusting the eggs, it looked like egg # 2 might also be pipped, but this was a much smaller hole. By 12:30 Astrid was back on the eggs. Ares came back with food at 2:48 PM. Astrid took the food and left the box, but was back within 5 minutes to relieve Ares again. It really seemed like she wanted to stay with her clutch today. At 5:35 Ares was seen feeding on the hotel ledge. It wasn’t clear what the prey was, but he never brought any of it to the box. We assume that he stored it instead. A switch at 6:00 gave us another look at the eggs and we could see that the hole in egg # 1 was larger, but we still had no hatchling in the nest. At 6:35 Astrid came to the box to relieve Ares. He didn’t want to leave and so she gave him her light chatter call. He still didn’t leave, and so she flew out instead. She came back at 7:15 PM and this time they switched. He returned 15 minutes later with a hunk of food. Maybe it was intended for the chick(s)? She sent him away with it. We end today’s report with 4 eggs still in the nest. Maybe one will hatch tonight? If not, we expect tomorrow morning will give us one if not 2 hatches.  We shall see

 

It was cold and rainy again today. In the early morning the temperatures were in the low 40’s and they moderated little as the day progressed. The first changing of the guard took place at 5:24 AM. About ninety minutes later Astrid was seen feeding on a fresh kill (pigeon) on the hotel ledge. She appeared to eat nearly the entire thing. At every one of the quick changeovers that took place today we inspected the eggs for pips, but none were identified. At 11:07, Ares was seen on the hotel with a small scrap of food (probably the scant leftovers from Astrid’s meal). While he was there a particularly fearless pigeon first buzzed by him and then perched only two feet away on the same ledge. We’ve seen this behavior before in recent weeks and we believe it’s an example of a pigeon protecting its own nest site. During the late morning Astrid may have been reacting to sounds emanating from an egg (or eggs). She called and adjusted the eggs in response. For a minute I thought I could hear some light peeping sounds coming from the eggs, but at the time the audio feed was cutting in and out and so I couldn’t be completely sure of what I was hearing. Ares came to the box at noon, obviously intending to take over on the eggs. She sent him away, but at 2:26 she was ready to leave and he got his chance to incubate.  The final switch for the day happened at 5:24 PM when Astrid returned to the box. Ten Minutes later, Ares was feeding on fresh prey on the hotel. The falcons have now completed 31 days of incubation. If things proceed as expected, Monday or Tuesday should bring them their first hatch.

 

 

It was a little on the chilly side in the early morning with some light rain. Later in the morning rain became steadier, but temps were more mild. Winds were out of the south and were packing some strength. Those winds ushered in some migrating raptors; although none that drew the ire of the falcons. The Peregrines did their first changing of the guard at 5:30 AM. At that time it was hard to see the eggs well enough to determine if any of them were pipped, but subsequent changeovers gave us more opportunities to view them and we can confidently report that there were no pips. This means we expect no imminent hatching. However, it is day 30 of incubation and we so can’t be too far off from a hatch. Today seemed to be fairly calm and incident free, but for most of the day both Deb and I were monitoring remotely from our phones and so it’s conceivable we missed some action. Astrid did leave the nest and the eggs at around 2:00 PM, but Ares arrived and took over incubating leaving only a two-minute gap. Review of the days recordings seemed to confirm that it was a no-drama day. At 5:00 Astrid took over at the nest from Ares and presumably Ares retired early to his night perch. Heavier rain and cooler conditions helped insure an early night for the pair. Based on experience from previous years, we predict the first pip and first hatch to take place sometime on Monday or Tuesday.

Today (Friday) was the 29th day of incubation and no “pip” was seen on any of the eggs – not that we expected that to happen yet. We believe we are still a few days out from the first hatch. Today was windy, cold and rainy and the falcons gave us precious few chances to inspect the eggs for pips. Their changeovers were generally very quick.  In fact neither Astrid or Ares wanted to leave the box when the other returned to take over. Once in the morning, Ares stepped on Astrid’s tail to get her to leave, but she wouldn’t go. In the afternoon, the opposite happened, and it was Astrid stepping on Ares’ primary feathers to try to shift him. That actually did work. At one point this afternoon, Ares brought his mate a food tribute (a portion of a Pigeon). It’s the first food exchange we’ve seen take place in a few days. We were beginning to wonder if that was still a thing! She took the food and he got a chance to incubate and stay dry for while. She took over again in late afternoon and they were set the night.

The morning started out quite cold, but Astrid was eager to get off the nest. At 5:30 AM, with Ares in sight on the State Building, Astrid left the box. Without missing a beat Ares swooped in and was covering the eggs before a minute was up. At Noon, Astrid was taking one of her turns on the eggs; Ares checked in on her, walked around her in the box, but she wouldn’t leave. The same thing happened an hour later and again Astrid wouldn’t leave. Instead she sent him out. At 2:13, an intruder in the canyon (reportedly an adult Peregrine) brought the pair off the eggs for a total of four minutes. Ares returned to the box and after a few minutes Astrid was back and keeping watch from a perch on the State Building. This close to hatching, it seems Astrid loathes to be out of sight of the nest. Astrid came over to check on the nest at 3:30, but this time Ares didn’t want to leave. She let him continue incubating until finally relieving him at 5:15 PM. The eggs were seen, photographed and scrutinized today, but so far there’s no sign that any of the eggs have been pipped. Friday will mark the 29th day of continuous incubation. We should see the first pip or even the first hatch within the next 3 days sometime.
