“Oh, oh, oh!”

Tenth day of incubation and all is going well so far other than a couple of scrapes with a visiting tiercel that is very aggressive. Both north and south side falcons have splashed him a few times in the bay.

I spent most of the morning with Cleve Nash, our generous and talented photographer, whose photos appear all over our web site. Thank you, Cleve. We were in the north parking lot, about in the middle, with spotting scopes and cameras blazing, plastic peregrine on the roof of my Ford Escape when a nice looking young middle-aged woman said, “What are you trying to attract with that plastic bird?”

I answered, “People just like you, and, I think, it is working.”

We chatted a bit and she saw the female perched outside the eyrie and asked if her mother could have a look. Mom in her “golden years” stepped up to the spotting scope. Just then the male left the nest site and proceeded to mount the female.

Somebody yelled, ”They’re copulating.”

Granma now has a firm grip on the eyepiece and uttering, “Oh, oh, oh!”

The daughter standing behind her says, “What’s wrong Mom?”

Mom said, “Nothing, I think, I just saw them do it.”

The daughter said “Do what?”

Mom said, ”You know.”

Daughter said “Really?”

Anyway, Granma went back to the car to tell Granpa.

A little while later, the daughter came back and said her Mom knew just what was going on, but didn’t see a penis. I explained to her it was a cloacal kiss* unlike ducks and geese who have phalluses.

Happy trails, Bob

Room service…


Photo by Cleve Nash

Today was a full day of confirmation. Brooding is in the routine now. For the first two hours this morning, the tiercel was in the eyrie brooding. I only knew this when I saw the female arrive about 10:55AM. She had been perched where she was not visible. When she landed on the edge of the eyrie, the tiercel quickly left and let her take over brooding. He hung around for half an hour, then off to the estuary for a kill.

He returned about noon, with prey hanging below. At the elevation of his return flight, the female can see him from a long way off, even while sitting on eggs.

I don’t watch the sky around or over the estuary to see him returning. I keep focused on the eyrie to see her poke out her head. Then I know, he will be here in a minute or so. Their eyesight is incredible. It never ceases to amaze me.

She greeted him on the diving board, took the bird and flew to “the chimney.” He walked into the back of the eyrie to brood. When she finished the bird, she took a couple laps around the rock, then back to the nest.

The tiercel, perching where we could see him, did not return to  relieve her for the next three hours. When he did, he brought her another bird, which she ate, then let him do the brooding for the next two hours.

So much for room service, I went home to king salmon and broccoli.

Sunday at “the rock”…

Sorry to take so long to getting back to you good followers but, I have been trying to get confirmation. Many keen observers are always helpful. Here is what I’ve seen and believe is happening. 

Yesterday, Sunday, the few hours that I spent at “the rock,” the female was in the eyrie and out of sight. The tiercel returned to “the rock” with prey. He went into one of his larders. The female, hearing his chupping on arrival, peeked over the edge of the nest site, thinking he would probably bring it to her. When he did not, she returned to brooding, not being off the eggs more than 30 seconds.

 The tiercel then perched high above the eyrie on the skyline. You could see his stomach soiled with reddish brown dust from the nest. Most likely, he had previously been sitting on the eggs. I had to leave before I saw any incubation exchange. Today, I think that I will. So, I believe, that would make Sunday, March 3, 2013, the first day of incubation.

Happy trails, Bob

Be patient…

Please be patient while we switch over to the WordPress.org website. We will then be able to bring you an eStore and other upgrades! We look forward to expanding our capabilities on the web. Meanwhile, Bob will continue his observations out at Morro Rock, Morro Bay, California, USA. The peregrines are in a very exciting life cycle period since they are about to begin incubating eggs. He’ll let me know when he returns this afternoon.

Thanks for your patience.  ~Heather

Soiled, but not foiled…

Soiled, but not foiled...

Photo by Cleve Nash

On the left you can see the female and her wet vent area. The male on the right has brought her prey to eat.

All signs, from observations, tell us that egg laying has begun. Cleve Nash and I have been monitoring the female very closely. Saturday she spent nearly three hours in the “diving board” eyrie, again on Monday, but not as long. We have both noticed visible soiling around the vent, which usually in an indication of egg laying. We, also, see that she is not so apt to do battle with the Red-tailed Hawks or the north side falcons. Let’s face it, you don’t get into a bar fight when you are nine months pregnant.

The tiercel is constantly bringing in prey, sometimes to her directly or stashing it in one of his many larders. If what we are seeing is correct, we should see incubation begin around the weekend of March 2-3. This will be confirmed by the tiercel taking his turn at brooding. In past years, watching this behavior, it seems the tiercel spends 35% of time brooding to the falcon’s 65%. The time off the nest that he gives her has to be spent eating, digesting and exercising so as to keep the muscles from atrophying. It is a delicate balance between the two to bring this about in a month’s time without the eggs being uncovered for more than a minute.
Happy trails, Bob

P.S. Before we had a WordPress website, we used Facebook to deliver information. This was our Facebook entry:

“March 4, 2012. This is the first day of brooding observed. At 12 noon there was an exchange. The female left the nest and the male went in to sit on the eggs.”

As you can see, we are only one day off from last year’s entry. That is if we are correct.

Favors in return…

Favors in return...

“Simone” Photo by Cleve Nash

A lot of nice people were visiting Morro Bay over the four day holiday. Many were able to see the “tall ships” do battle outside the bay and many saw the falcons for the first time in their lives. A few of the lucky ones saw them breeding. You can’t imagine the comments from people who don’t know each other gather around a couple of spotting scopes when all this sex is taking place. How is it that people can talk for twenty minutes about a fifteen second interlude? The tiercel is still bringing her prey items either from stash sites or fresh kills and receiving sexual favors from her in return. Does this sound familiar?

While it was so busy and crowded in Morro Bay, Cleve Nash, a photographer who doesn’t care for crowds, took a short drive up the coast from his home north of here to San Simeon. It’s a cove with a beach and a pier that was used to offload materials and artifacts for William Randolph Hearst’s castle. In the parking lot, Cleve noticed a female peregrine in a pine tree. She flew to a pole where he noticed the unusual coloration around the mustache which connected to the sideburn, forming a circle. Cleve didn’t remember seeing this bird even though there are a few along that part of the coast.

I said “Call her ‘Simone.’”
Cleve said “I don’t know about that. My wife didn’t mind too much about my seeing “Doris” in Baywood, “Judy” in Morro Bay and “Shelly” in Pismo, but “Simone” just has a different ring to it.”

Presidents’ Day weekend…

Presidents' Day weekend...

Photo by Heather O’Connor

As we continue to observe the antics of the breeding peregrines, this holiday weekend brought two tall ships, the “Lady Washington” and the “Hawaiian Chieftain” into Morro Bay, California. A delightful day in the low 70s with many visitors stopping by to see the tall ships and frequent copulations of our resident pair.

Just to review: Our resident falcons breed here around Christmas and New Years’ holidays in December/January, egg-laying starts in March, chicks hatch around Easter in April, fly by Memorial Day in May and by Labor Day in September, the parents chase them off.

As time passes, Bob will let you know the exact dates for each event this year.

A few inches apart…

A few inches apart...

One warm sunny day and everything starts happening. Breeding is nearly in full swing. About three times within a four hour period on their arrival to the “rock,” the south side falcons flew into the diving board eyrie and spent some time in the back not visible to the three of us watching intently. After about five minutes, the tiercel (male falcon) appeared on the diving board, with a short jump, he was airborne and off around the face of Morro Rock. A short time later, the falcon (female falcon) did almost the same, but flew to the “chimney” and perched. Within a few minutes, the tiercel returned with prey. She spotted him incoming from the west over the water as she flew from the chimney which alerted us to see him. They were converging on the eyrie from opposite directions. The female landing first, one second later, the male landed. Before he got his balance she had taken the prey from him and was back on the “chimney” plucking. While she ate, he chased vultures. She left the prey after a few bites and then left it for him to finish. For the last few days, they have been standing a few inches apart with up and down head movement almost like they were talking. I wish I knew what they were saying.

Also, today, the vultures are around their old nest site landing behind the rock where last year’s chick “Spec” (see story dated: Tuesday, August 7, 2012 ) was first seen. I have not seen any coupling yet, but I will keep on top of it.

The next four or five weeks will be prime time for the falcons as they will be at the height of the breeding season and do not leave “the rock” much!

A Golden voyage…

Photo of last year’s young Golden Eagles by Cleve Nash

Cleve Nash, our resident photographer, and I took a ride out to Creston, CA, where my daughter and her family live. There had been numerous eagles, Golden and Bald, around her pond on her property. A few waterfowl and kingfishers, but no eagles.

On our way home, we took the back way down Highway 229 then went towards Margarita Lake. We stopped by the Golden Eagle nest that Cleve had filmed last year with two young in the nest. No activity around the nest yet, but one perched about 100 yards off in a Digger Pine. Not a quarter of a mile down the road, we came upon three Bald Eagles all in the same tree, one adult and two “juvies” (juveniles). As we watched, three wild hogs ran across a newly planted oat field. Still watching the three eagles, a Prairie Falcon flew over the highway, then a Golden Eagle perched in a pine 500 yards away. All in all, it was a great day away from the busy-ness of the Morro Bay Winter Bird Festival weekend at Morro Rock.
Update on the injured Golden Eagle: His appetite is great; he ate a big rat today.

Outside…

Outside...

Photo by Bob Isenberg
Outside at “the Rock” during the Morro Bay Winter Bird Festival, visitors use spotting scopes set up to see the peregrines and have all their questions answered.

The Morro Bay Winter Bird Festival was a great success! The weather was gorgeous, 70+° F . On Friday, numerous leader-led groups of birders stopped by to learn about the peregrines. On a following day, “the Rock” was another story with 30+mph winds and high surf so the gate to our special place where we set up our spotting scopes and chairs was locked. Without my truck and camper, I had no windbreak for my equipment.

On Friday, my daughter called from her inland ranch while I was at “the Rock” and said, “I have a Golden Eagle by my pond and it’s injured!” I told her what to do. She got it into a portable dog kennel with the help of two adults, two “tweeners” and one dog. Ninety minutes later and a quarter of a mile from where it was first found, it was secure and ready to be taken to town and Pacific Wildlife Care. They told us it was a male and had a large wound in the patagium* in the wing with a small whole in an unbroken bone. We’ll keep you up to date on its recovery.
Happy trails, Bob
