Astrid in to take over on the eggs

Astrid on the steeple after eating – note the big crop

It was cold overnight with temperatures in the mid to low 30’s. Clearing skies in the morning led to a warmer midday. It was in the mid-50’s by lunchtime and in the 60’s in the late afternoon. Astrid spent all of last night on the eggs. As referred to in yesterday’s post, she relieved Ares at just before 2 PM on Wednesday and he never came back to relieve her. Essentially, she sat incubating from 2 PM until 5:30 AM when Ares finally showed up. Interestingly, we didn’t notice her calling out for him, nor did she fly out and try to fetch him. We never did locate him with the cameras. Our best guess was that he was out on an extended hunting trip and was, perhaps, filling his pantry ledges on the west face of the State Building. So, Ares finally showed up for a switch at 5:28 AM. He took over incubation and Astrid flew into the canyon. At 5:52 she was flying around the west face of the building and perusing Ares’ pantry ledges. Apparently, she selected something. After perching on the west face for a little while, Astrid brought her meal over to the hotel. She ate it, but wasn’t satisfied. At 6:09 Astrid was on the northeast corner of the building’s upper ledge. She was in hunting mode. She made a couple of fast forays to the east, each time returning to the corner. She was back to the box for a changing of the guard at 7:29. At 9:36 Astrid was vocalizing while sitting on the nest, and she kept calling periodically (about every 5 minutes) to get Ares’s attention. She kept this up for over an hour. Meanwhile Ares didn’t seem phased or compelled to do anything. We think she was asking for him to bring her food.

Another quick switch

At 10:42 AM the pair switched again, and Ares was back on the nest. At 11:23 Astrid was back on the hotel corner and, once again, she was hunting. She moved to the State Building at 12:47 PM. At 1:30 it was Ares’ turn to vocalize. He starting making chirping calls – the kind he gives when there is an intruder in the canyon.  He flew over to the State Building and landed near Astrid. She flew to the box and resumed incubation. She was still calling out to him after the switch. We believe that she wanted him to bring her some palatable prey – you know, for a change. At 3:28 Ares returned to the nest and the two falcons did a fast changeover. Astrid was on the State Building for a while but then she was out of view. At 4:34 PM we noticed that she was feeding on something on the hotel. She had either caught something herself (presumably a Pigeon) or she found something good in Ares’ cupboard. There wasn’t enough left of it for us to identify it at such a distance. At 4:44 she was on the steeple perch and her crop was pretty big so she had eaten well. Meanwhile, it was getting warm in the nest box and Ares was panting. The temperature was in the low 60’s but the sun was flooding the box. Ares was switching between shading and incubating. At 5:00 PM Astrid came to the crossperch. She sat there for about five minutes before coming into the box and relieving Ares on the eggs. This would be the last switch of the day. Ares was on the State Building for a little while after that and then up on the lookout. He flew from there at 7:15 PM. Goodnight falcons.

Winter’s Slight Return & Astrid Pulls a Marathon Sitting – Where is that Ares?

Quick Switches were the rule today

The overnight was cold with intermittent mixed precipitation. The low was 35 degrees and the high for the day was only 41 degrees, although it felt colder due to a persistent wind. Rain and snow fell periodically through the day. Astrid was on the eggs all night long. Ares first showed up on the State Office Building just before 6:00 AM. The falcons did a quick switch at 6:06 and Ares took over incubation. The next changing of the guard was also quick and took place at 7:44. Astrid then took over on the clutch. At 9:21 Ares was seen flying high over the southwest part of the canyon. Likely he was hunting. Astrid called out when he returned and landed on the State Building. At 12:04 PM Astrid vocalized again when Ares was floating around the west face of the State Building. At one point he darted off towards the east at high speed. At 12:23, another quick switch occurred and Ares had a turn on the eggs. At 1:55 Astrid was back and another switch was at hand. Astrid quickly settled down on the eggs as Ares floated off on the gusty wind. At 5:07 Astrid was still on the eggs and Ares was nowhere in sight. We wondered if he was going to get one more shift in before nighttime. As it happened, we didn’t see Ares for the rest of the day. That meant that Astrid was going to have a marathon sit on the eggs – lasting the balance of the afternoon, and all night. Indeed, she couldn’t be too happy about that. Goodnight all.

Cool and Wet Day – Intruder in the Morning

It was cool and rainy overnight. The temperature was in the high 30s. Conditions did not change much during the day. The high temperature was only 43 degrees and there were intermittent rain showers. Astrid spent the night on the eggs. Ares showed up on the State Building just before 6 AM. He moved from a ledge to his lookout post at one point. At around 6:10 he came to the box and the pair did a quick switch. She went over to the State Building while he worked to cover all four eggs. At 6:46 Astrid was on the steeple. She wasn’t there for long and soon went somewhere invisible to our cameras. At 7:24 she was back to the State Building. Ten minutes later she landed on the crossperch at the nestbox. She quickly discerned that Ares was not ready to go and she flew off once more. At 9:11 Astrid was back, and this time Ares did allow her to take over on the nest. When he left he headed to the exact same ledge on the State Building that Astrid had been on. At 9:30 Astrid began calling from the box. Ares was dealing with an intruder. Both Falcons headed off towards the north with Ares in pursuit. Ares returned only a minute later and landed on the lookout post. He moved to a window ledge after a couple of minutes. At 10:30 Astrid was calling again. We don’t know what brought that on. Perhaps the intruder had returned. At 11:37 Ares was on the State Building again. Ten minutes later he came into the box to try to have a turn incubating. Astrid did not want to leave. There was a lot of conversation, but she opted to stay and flew out. He floated back over to the State Building. The next changeover happened at 12:58 PM. It was a quick switch. Ares took over on the eggs and Astrid was out.  At 2:34 There was another changing of the guard. This time Astrid took a turn. By this time, it had gotten colder and we were getting intermittent mixed precipitation. We didn’t see Ares for a while, but at 5:10 Astrid started calling like she saw him. Sure enough he showed up on the State Building right after that. Just when we were starting to wonder if he was ever going to relieve her on the nest he showed up on the west veranda with food. Astrid got off the eggs, danced across the crossperch, and took the food from him. She flew over to the hotel to eat it. After she finished it she pulled over some hunk of leftovers that had been sitting on the same ledge and started picking at it. She didn’t seem to like it and, after a minute she flew over to the State Building. At 7:21 the falcons did their last switch of the day. Ares flew over to the State Building and Astrid settled onto the eggs. He was off to his night perch fifteen minutes later. Goodnight all.  

Heat Spell Broken – Back to Cool Days and Rain

Overnight the temperature dropped from the 70s to the 40s. Overcast skies, rain, and wind returned. The high temperature for the day was 50 degrees. Astrid spent the whole night on the nest. At 6:00 AM Ares gave a few long calls – we think from the State Building. Astrid called back to him. Two minutes later Ares was at the box asking for a turn on the eggs. She didn’t want to leave, and sent him out. At 6:46 Ares came back and by that time Astrid was ready to go. It was a very quick changing of the guard. Astrid flew over to the State Building. At 8:01 Astrid became upset when she saw someone in an office window near the nestbox. She hazed the 15th floor of the building a few times before settling on the crossperch. She requested a mating and Ares complied. It is now eight days after the last egg was laid and yet they are still occasionally mating. Astrid came onto the eggs at 8:02 and Ares went to the State Building.

At 10:03 the Falcons switched again. Ares was having some difficulty getting all the eggs tucked beneath him, but finally managed it. At 10:37 the Falcons switched again. This time Astrid was coming onto the eggs. At 1:27 PM Ares was on his pillar perch. They switched five minutes later and then Ares took a turn on the eggs. Astrid had been on the hotel before that. The next changing of the guard was at 3:07, and the next was 4:33 PM. They were all fast changeovers today. At 6:30 Astrid was on the hotel and their was a Pigeon sitting on the same ledge – about 15 feet away. At 6:32 PM she flew to the nest. She asked to take over and Ares complied. It was likely that she was in place for the night, Ares went to the State Building for a little while but then he was off to his night perch. It began raining again by 8:30 PM. Goodnight all.

August Weather in April Continues

It was slightly cool overnight with temperatures in the high 50’s. For the fourth day in a row, the temperature rose quickly through the morning and reached into the mid-80’s by mid afternoon. Astrid was on the eggs all night long. Ares came to the nest at 5:24 AM but Astrid was not inclined to leave. He left instead and came back a half hour later. Astrid still refused to leave and so he went over to the west veranda. As it happened, the third time was the charm. When Ares asked again at 6:16 she agreed to leave and he was able to have his turn on the eggs. She went to the State Building for a little while but was then out of view. At 8:15 Astrid was back at the box and requesting a shift on the eggs. After four minutes of gentle persuasion, Ares consented to go and she got onto the clutch. At 10:28 Ares was on his favorite pillar perch having a grooming session. He took off after something at one point but then returned at 10:43. At 11:29 Ares was at the nest asking for a turn on the eggs. When she didn’t get up right away, he walked around behind her and ousted her. He got comfortable on the eggs as she flew over to the State Office Building.

At around 1:18 Pm Ares abruptly darted from the nest – leaving the eggs alone. It was about 80 degrees at the time. Certainly, the eggs were in no jeopardy of getting cold. We don’t know what prompted Ares to leave. We weren’t monitoring sound at the time so we don’t know if any alarm calls were given. Astrid came into the box less than a minute later and got onto the eggs. Ares returned to the nest at 3:00. Astrid’s tail was draped over the lip of the box and he stepped on it. That compelled her to get up and leave the box. He then took over on the eggs. Once again, Ares’ shift took place at the hottest time of the day. He did a lot of shading. We didn’t know where Astrid was for a while but at 3:54 she showed up on the north face of the State Building. At 5:49 PM Astrid was back to the box and asking to take over. Surprisingly, Ares didn’t seem to want to leave. She stood along side him for a few minutes (the two of them were casting odd shadows on the back wall) and then the pair did some beaking. Ares got off the eggs after that and left the box. Astrid took over on the clutch and would likely stay in place until morning. Goodnight falcons.
