Monday evening was one of the nights where Flaco quickly disappeared. He flew out fairly predictably, going to a tree northwest of Andrew Haswell Green Bench, then to a tree just inside the construction site. However instead of exploring the construction site he went to Nutter’s Battery and then flew due south of the Compost Heap, before disappearing.

He had brought a rat to his roost and had eaten it around 4 pm. We wondered if on the days he eats at this roost, he is in no rush to eat early and instead he explores.

I was busy watching a Marsh Wren at the Nursery, so I missed Flaco’s fly out. I caught up with him as he explored the construction site. He then went to the Compost Heap and quickly caught a rat. He ate it on the highest dirt pile, but then stopped half way through eating. He did this last night at the construction site too.

He then hooted in trees to the north and south before returning to the dirt pile. He continued eating the rat but some raccoons caused him to move to another dirt pile. He finished eating and then quickly went north. We couldn’t relocate him.

I arrived after dinner to find that Flaco had caught a Brown Rat at the Compost Heap, and had been flushed so that he moved to the Harlem Meer construction site to eat it. When I arrived most of the owl watchers thought he had finished it, but at least half of it was right in front of him. He would make some flight but returned to retrieve the rat and then ate it on an excavator. He got startled and then took the rat to a second excavator. Once he was finished, he flew to Nutter’s Battery and started hooting. It was late and knowing he can hoot for hours, we all went home.

Without meaning to I spent six hours with Flaco last night.

He flew out as he normally would waking up and doing some stretches before leaving his roost tree. He made a quick stop and hooted from the overlook of the Green Bench area, before flying to a tree on the Ridge Trail that overlooks the construction site. He hooted there for over an hour in dense foliage.

We heard him stop hooting and he appeared on an excavator in the center of the construction site. He made a series of visits inside the new building, and retuned to the excavator a number of times. He then left the construction site.

We heard him hooting and he was in a tree that overlooks the Harlem Meer. His presence upset a flock of Canada Geese, who moved around in response to his presence. When he left his perch, he flew over them and they scattered.

He then went to the Compost Heap area, where he stayed in his favorite tree, before making a quick trip off of it. We couldn’t see where he went, but he soon returned to the tree. After some time, he then flew to a pile of rocks and then a concrete pipe. He left the pipe a few times, but kept returning to it.

Around Midnight, he left the Compost Heap and began hooting in a tree along the East Drive.

Today, Flaco wasn’t in any of his normal roosts. An owl watcher saw him flying south along the East Drive around 97th Street, so he might have roosted in a tree near the Southwest corner of the East Meadow or the Southeast corner of the eastern half of the North Meadow.

Because he was seen going south of the 96th Street Transverse the search for him started there and at the Tennis Courts but he wasn’t found. I backtracked north, to the meadows, compost, Nutter’s Battery and construction. I then heard him hooting from Nutter’s Battery. He was first in a tree at the northeastern side of the construction site and then continued hooting from his favorite tree in the area. But just as we started to photograph him, he left.

We relocated him in his favorite tree at Compost. He went to the ground twice. He seemed to miss on the first try, but if it was little he might have eaten it on the spot. On his second try, he caught a small rodent. He returned to his tree and ate it in one or two bites. I accidentally didn’t record his eating.

He then relaxed and even close his eyes for a few minutes. After the long evening of Saturday night, I went home. However two other owl watchers stayed to see if he would continue hunting.

When you watch owls, you have good night and bad nights. Owls can easily disappear out of view or perch for hours. Recently, we’ve had a string of difficult nights.

However, Friday night turned out to be one of the best nights I’ve had watching him. The group watching him had him in view for four hours and he hunted on the ground near his roost tree, caught a Brown Rat (or possibly retrieved a previously caught rat that he cached or had fallen from his roost during the day), ate the Brown Rat. Later, in the same spot the Snowy Owl bathed, he played in the water and took a bath.

It was a wonderful evening.
