5 May 2013: With a threat of rain which will probably never happen, we are still waiting for the appearance of falcons on the north side of Morro Rock. The north side pair have had a steady stream of prey going into the nest by the tiercel for at least 2 plus weeks, but still no fuzzy ones to see.

Jack Morehead, one of the guides at Piedras Blancas Lighthouse, came by the rock to tell me “the pair of falcons that nest there have three young that are visible now.” This particular site has been troublesome and have not had young for some time. The previous years, have been plagued by having only half of a pair, either male or female or a failed nesting when there were two birds present. It is good to see they are in production again.

The falcons on the south side of Morro Rock continue to incubate eggs now in the fourth week. Other than a couple of visits from a juvenile female falcon which has been driven off immediately by one or both resident falcons. Things continue to progress with the new set of eggs in the secondary eyrie. The first clutch of eggs as you remember were in the “diving board eyrie” and were abandoned after 16 days of incubation. This second nesting has nearly doubled that time and “with a little luck and the creek don’t rise.” You know the rest of it.
Happy trails, Bob

Item: Rosie finds love.
At the Shell Beach nest site, a tiercel has arrived and taken up with the rosy-breasted female resident who has been on her own since the last winter.

Looking and waiting…

With no fuzzy chicks to look at yet, we have been relegated to looking at a “rock” that once every few hours might show some movement. Otherwise, it is like watching paint dry.

After telling dozens of birders, tourists and surfers that “you can’t see any chicks yet,” not to be discouraged, a few of us took a ten minute ride north of town to see some white fluffy chicks. Three Red-tailed Hawks have nests within half a mile of each other. All of the young are sticking their heads up over the edge of the nests. The female of one nest sat at a distance in an old oak with a snake.We thought it time to leave so she could come in to feed the young.

So back to “the rock” to enjoy the boredom of incubation and thinking with great expectation, “Soon!”

A spring gale…

I’m still getting days with high winds which is not unusual for spring weather. Today 12 to 15 foot swells at sea with wind gusts up to 50 plus miles per hour. We have included our photographs of blowing sand and Coast Guard Station gale warning pennants.

I’ve been watching the three new chicks on the webcam at San Jose City Hall, California and I am envious. I can’t wait to see something here at Morro Rock that resembles something white and fuzzy like a chick, but we don’t have the privilege of having a camera in the nest site so we’ll just have to wait until they are strong enough to come to the opening and then we can get a head count. I love the suspense, but hate the wait.

Aside from the two falcons’ nests at the rock, we will have a black turkey vulture nest site to watch. If you remember last year, they fledged one young vulture.* I did see the adults copulating near the eyrie earlier this year, but like the falcons we won’t know until the young stand up behind the rock that hides the eyrie.

The Western gulls are staking out their territories and breeding has just begun in the last couple days. Nest building should start soon.

We have added a couple new pieces to our arsenal of equipment. Cleve Nash has just acquired a brand new 600mm lens which weighs 2 1/2 ounces more than the old 500mm that it is replacing. Also, my daughter gave me for my 72nd birthday the new two piece Swarovski 95mm spotting scope, 30-70 power. This has to be the Cadillac for birders. “Thank you, Molly!”

Morro Rock offers an up close and personal visit with peregrine falcons. If you get a chance while traveling the Pacific Coast, stop in and see them. It won’t cost a dime.
Happy trails, Bob

Now hear this…

Not tonight, honey...

“Now hear this. Stand clear of all weather decks, due to high winds and heavy seas. Batten down all loose gear.” You can bet the peregrines are hunkered down with wind gusts to 60 mph, white caps and sand blowing across the beaches, but all is well with both pair of falcons.

The north side pair are due to hatch sometime this week. We are looking to see her take prey into the eyrie. This will be the first indication that the chicks have hatched. After that happens, we should begin to see the young ones in a couple of weeks when they come to the edge of the nest site to defecate. Teetering on the edge of certain death, they will show no fear and will do their business.

The south side pair after abandoning the “diving board” eyrie, re-grouped, re-bred, re-clutched and have been incubating for the last week. As much as we hate to see the loss of the first set of eggs, it gives us a wonderful opportunity to watch the north side chicks develop, feather out and fledge and then we will be able to see the south side young go through the same scenario when the north side chicks are flying.

Cleve Nash is working on a third pair in the county that is trying to set up housekeeping. The tiercel is making his best efforts to breed, but she has rejected his amorous moves several times so far. If this works out and she comes around, we could have babies well into the summer!

Hopefully, this weather that we are having will calm down a little and I will be able to set up some spotting scopes. It’s hard to write about something when you can’t see what’s going on.

Mildly obsessive-compulsive…

Bob and I had been talking together about how to introduce to you our friend, the fine photographer, Cleve Nash. So that we would have examples with which to educate everyone, he has been generously donating his photographs. They cover all examples of the life cycle of our peregrine falcons along with other visiting birds. After a couple requests to Cleve, I received an email with the following. ~Heather

“Heather has asked me write a bit about why and how I came to take so many photos of peregrines.

It all began about ten years ago when my decades of photography and videography had distilled to a passion for capturing video of the Pacific and its mammalian inhabitants, particularly southern sea otters. One spring day I was at Morro Rock wrestling with a cumbersome but effective setup that mated a large professional camcorder to an even larger astronomical telescope when one of the local watchers suggested I go around to the south side and try my gear on the nesting peregrines. Just for the heck of it, I did and managed through sheer luck to grab some action that I thought was pretty cool. So was launched a mild obsession.

Photographing peregrines at Morro Rock is challenging. Except for a couple of days when the young first fledge, the birds stay very high. It is rare to get a shot of less than 100 yards. A chick in the diving board nest? With a decent angle, you’re talking 150-160 yards. A good camera with a big lens will get reasonably good results. But if you want the feather and fuzz detail of that nestling, you are faced with the trials and (few) tribulations of digiscoping. You no longer have the luxury of automatic focusing, and that 150 yards is filled with heavy, moist moving air that distorts the image entering your camera like heat waves rising off a desert highway. Add the Rock’s nearly constant winds that rattle your gear — at very high magnification, the smallest vibrations are highly magnified too — and getting a sharp, well exposed image becomes the holy grail and the great white whale for even the mildly obsessive-compulsive. Can’t wait for those babies to appear. Hope I can get some good shots for you.”

Taboo…

Observations continue on both north and south side pairs of peregrines. Cleve Nash has been mostly watching and photographing the north side, which are in about their second or third week of incubation. All is going well. The north side of the rock is good for photos of food exchanges and action over the large parking lot where Cleve is not usually shooting into the sun. For more general purpose photography, the south side can be better being that the birds are lower and usually closer with the sun behind you.

I am for the most part, set up on the south side. This pair of falcons continue to breed and frequent the “lower five” nest site which was used in 2011, after a previous failed nesting that year. Today she spent two hours in there, then out and about flying and perching. So, I believe, this is egg laying behavior. We should know by this weekend. During the time I have been at the rock this week, I have not seen them come close to the “diving board” nest site, since they abandoned it a week ago. It’s like the hole is taboo.
Happy trails, Bob

Thanks, Heather

Cause unknown…

Photo by Bob Isenberg

Yesterday, I thought something was strange when she left the “diving board” nest site, and the tiercel did not go immediately in to take her place on the eggs. Instead, after she left and landed on the chimney, he proceeded to follow her there upon landing. They copulated there. Neither bird returned to the eyrie for ten minutes, which I thought was very unusual because it seems the eggs are never unattended more than a minute.

Today on arriving at Morro Rock, I saw both falcons perched in different holes. The female was on the edge of one she used as a nest site in 2011, after a failed nesting in the “mail slot,” another previous nest site. The tiercel was perched above her in a second row of five holes. Today in the few hours I spent with the birds, neither of them went to the “diving board” nest site, but remained outside in view copulating twice and frequently returning to the 2011 eyrie.

This has really rattled me to think they incubated the eggs for 16 days then phhhhht… What could have happened? I’ll still be here watching and hoping for a second clutch of eggs and keeping you posted. It happens. This isn’t the end.

Happy trails, Bob

“Oh, oh, oh!”

IMG_0327Photo by Heather O’Connor

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.

Happy trails, Bob
