Cacophony of cacking…

Got an early start today. No more banker’s hours. Cleve says, “No wind and more action in the early hours.” It’s before 7AM and I’m here with coffee for both of us and Cleve is AWOL. Too bad he missed a great day and the first aerial food exchange between parent and juvenile. You guessed it “Flyboy!” Who else could fly that well.

When the parent arrives with prey, the cacophony of cacking* begins and soon all the young are airborne. If one or more does not fly, the parent will fly over them with prey to encourage them to come up and take it from them. Today, two of the young gave chase, “Flyboy” and his very large sister. It was no contest for him until he had to carry it to a perch. That is when she overtook him. Closing in fast on his yellow tail feathers, he dove into a bush squealing all the way, trying to mantle the prey even before he got stopped. The young female broke off the chase at the bush and later finished what he could not.

Happy trails, Bob

“Flyboy” can be identified by two blonde streaks on the back of his head.

“Flyboy” at speed                                                                 Photo by Cleve Nash

Today is a new day for our young aviatrix. She flies! After spending all day and night climbing around the cliffs and rocky slopes, the young female was the last to fledge in a cast of three. Both brothers fledged earlier this week. It must have felt wonderful to see mom bringing in breakfast after last night’s lonely ordeal.

Today, flying way beyond his means is “Flyboy.” I shudder watching him as he makes moves he has never done before. High “G” turns, stooping for two or three seconds, then flaring off to buzz one of his siblings or parent and missing by merely inches. I am awestruck and I have seen this many times before. He has to be like a cocky test pilot climbing into a new fighter aircraft and saying, “OK, let’s see what this baby can do!” And believe me if he could do what “Flyboy” did today, I guarantee that his linen would be soiled.

It is to a point, where I fear for him, if he keeps this up. I think we as humans cannot comprehend the power, the skill, the intelligence of animals. They simply amaze.

Happy trails, Bob

A tale of two tails…

Today, Memorial Day, we have two airborne falcons and one still grounded in the eyrie. However, “Flyboy” has returned to the nest site at least twice today. Seems he’s a little ticked at late meals or, at least, food going into the eyrie and not to him. The second chick to fly is a male, also. We believe the third that has not flown is a female.

After looking at yesterday’s photos, Cleve and Heather decided a photo of a chick flying was actually the second one to fledge. Cleve had noticed in the photo that the two lateral tail feathers on either side were not fully developed, creating the appearance of half feather half shaft. The photo above clearly shows the undeveloped feathers of the second bird. Previous photos of “Flyboy” do not show this, but instead fully developed feathers.  “Good job, Cleve!”

With all the excitement of the young fledging, we have had quite a gathering of long time peregrine observers. Steve Schubert of Camp Keep, Judy Sullivan and more. Last Friday, we had conducted peregrine programs for Mrs. Washer’s and Miss Ward’s second grade classes from Bishop Peak Elementary School, San Luis Obispo, CA. Some of those students with their families were out to see the peregrines today.

I hope your holiday was as good as ours.
Happy trails, Bob

Cold and hungry…

Two cold nights on the rock all alone got young “Fly Boy” motivated. We found him early this morning some 300 yards from where we left him the night before. After watching for a couple of hours, with a few rough landings he wound up in what we have always referred to as the “nursery.” It’s the far left end of Morro Rock on the North side where a lot of blasting and removal of rock took place and left high shear cornices, but below a gentle slope covered with brush, ideal for controlled crash landings.

Cleve and I watched as the parent brought him food, not one, but two birds. He didn’t finish the second and the parent female returned and ate it.

It’s amazing how fast they can find a chick. They will do this with all of them when they are flying no matter where they land. We left him on a narrow ledge high up under the  cornice with his crop full to the throat.

Happy trails, Bob

Launch or lunch…?

Out of the nest                                        Photo by Cleve Nash

So much for all our predictions, calculations and educated guesses. They are all “out the window,” now that one of the chicks has left the nest. I had expected the chicks to fly on the 1st of June. Although he hasn’t flown yet, this is the normal procedure before flight. Chicks normally fledge on or around Day 44. We estimated that we are at Day 36, so somebody goofed.

This morning about 8:30AM, I arrived at the rock to observe the three young falcons. Seeing nothing around the nest is not unusual. They could be sleeping. Then I caught movement twenty feet above the nest site. One of the young, flapping its wings, ventured out of the eyrie. I watched as it clung to the rock with talons and beak, all the time gaining altitude and flapping vigorously. There are gull nests in every direction and the gulls are not happy about this youngster roaming the neighborhood.

I watched the adult tiercel arrive with prey, the female cacking vociferously and chasing him to make the food exchange. With prey in her talons, she is inbound to the eyrie. The chick that had ventured out of the nest is squealing and flapping and it looks like he’s going to miss a meal.

I’m sure he or she will fly today. Thus is the normal procedure, to climb as high as it can and then jump. They picked a terrible day for learning, with wind gusts up to 55 mph and steady 30-35 mph breeze. This first step is when the young are most vulnerable. If they are able to fly, rarely do they make it back to the eyrie. They usually spend a cold night clinging to a ledge with no siblings for company or warmth. The biggest threat would be a Great-horned Owl. If he or she makes it through the night, with luck I will find him in the morning.
Happy trails, Bob

Cleve said “And now there are three!”

Three of a kind                                                Photo by Cleve Nash

Wind has been the order for the last few days. First from here, then from there and very little break in between.

Yes, there are three young chicks you see in the photo by Cleve Nash taken this morning, in a twenty mile per hour breeze from east to west. When I asked Cleve for a photo of the baby falcons for this posting, he warned me, “It might be fuzzy because of the wind.”

About 10:00AM we seemed to have an opportunity when the wind changes direction and reverses now, west to east. We get a little lull, but then the young falcons disappear. By 10:45AM and the wind has picked up to 40 mph, they want to come out to see what is going on. Cooperation between birds, wind and photographer can be challenging.

The third chick, seen here on the left, although it’s not readily apparent, seems to have more down compared to the other two. It may be a couple days younger than the other two. The two darker ones have ventured over to the mother’s perching spot on the left side of the eyrie (not shown in this photo). To get there, they had to make a small jump and I think they surprised themselves. One strong flap and they were up on the sloping rock.

Their wing feathers and tail are fully developed. They just look ungainly because of the down still clinging to them in obvious spots. Remember, these birds should fly in 12 days, that’s June, the first, if our calculations are somewhere close.

None of us here at the rock have given up on a fourth chick.

Two peregrine chicks                                                                               Photo by Cleve Nash

Saturday is always a big day, especially if the weather is nice. No one is disappointed today, surfers, sunbathers, kite-flyers, and some to see the falcons.

By 7 something AM, Cleve Nash had seen three young and believed there might be a fourth. The photo above shows two distinct heads of chicks, but they are so camouflaged by grass and lichen-encrusted rock, there could be five.

I sat twenty feet away from Cleve with spotting scopes, four birders from Tasmania to Bakersfield with binoculars and cameras and still saw only two! The young seem to appear just after a parent bird arrives with a fresh kill. One of the chick claims the kill and mantles* it, keeping the siblings away until he or she is full. During this time, the other young appear as if they are looking for more food to be delivered. This is when they are visible.

If you are making a trip to see the young, know that the adult birds bring in prey items about every hour, so bring a chair and be prepared to stay at least that long. Some folks walk by, look in one of the many scopes to see the babies and feel they have accomplished it all in five minutes. Remember that you are on bird time and be cognizant of that. Hope to see you soon.

Happy trails, Bob

*mantle, verb – a bird of prey on the ground or on a perch will spread the wings and tail, so as to cover captured prey.

Through the ages, a visual aid to the falcon chicks…

Posted on May 15, 2013 by Pacific Coast Peregrine Watch

 Day 1 to 24

Day 1 to 24 
Day 25 to 48

Day 25 to 48

Now that we have young visible chicks in one of our nest sites and more soon to hatch on the south side of Morro Rock, I wanted to give you, our readers, something so that you can follow the progression of the young either here at Morro Rock or on the Internet via the many nest cams you may find in the United States, Canada and around the world.

Be sure to click on the images above to enlarge them. This is a series of photographs, from egg to fledgling, and every day between. This series was done in Germany by a renowned woman who has since passed on. Cleve Nash and I both have copies to see how close our observations are, ie: egg laying, first day of incubation, first day of feeding, etc.

Over the years, with these photos and our observations, I would give us a grade of “A-.” Where we always fall short is trying to determine the number of young that will hatch on any given year. At best, it’s a crap shoot. Without seeing into the eyrie, or weighing the amount of food that goes in, forget it!

Today is Tuesday, and I spent five hours watching the nest site and saw three prey items go into the nest. I never saw a chick. Yesterday, I saw two young falcons. Maybe by Friday, I’ll see four!
Happy trails, Bob

Have some fun.
By looking at the photos that we post with our stories, compare the chicks to the progression series of chicks. See what day you think matches the age.

First sighting…

Posted on May 12, 2013 by Pacific Coast Peregrine Watch

Photos by Cleve Nash

Actually happened May 11 and 12, 2013.

8:30 AM First sighting of young falcon chicks occurred on the north side of Morro Rock and Cleve Nash was there to capture the first photographs. I got there about 9:30AM and spent the next six hours and never did see one.

However, Sunday was another day and I am setting up a scope and getting Heather comfortable out of her walker into a chair (NEW HIP REPLACEMENT) so she can see the nest.

Then Cleve yells “Fuzzy chick!”

Needless to say I missed it again, but Heather and our new found friends from New York, Sue and Howard, did see the chick!

The nest sight is set in a cluster of three holes similar to what you would see in a bowling ball. Two holes below and one above. The eyrie being the lower left of the two. There seems to be a passage between the two lower holes hidden by tall grasses. After observing for most of the day at least two chicks have ben moving through this passage, but you can only see glimpses of them moving from hole to hole. Throughout the week, we will be seeing more and more of them. Cleve did say that the chicks age by plumage coincides with when we first saw prey taken into the nest on April 18th.

Happy trails, Bob
