Conclusion: All Eagles All The Time: Season 2010/2011.


We have followed the Eagles ... on cam ... on the *Sauces Canyon Nest ... Two Harbors Nest and the West End Nest .....
From their early Nestorations .... through Bonding .... Eggs/Incubation .... Chicks .... Banding to Fledging.

K-10 and K-26 started to do nestorations at their usual nest at Pelican Harbor but there was a big hole in it and eventually they abandoned it and when another nest was discovered the camera was moved to it. However there was no action at that nest and so the IWS Crew started searching and discovered Nest #3. Unfortunately a camera couldn't be installed there.

* So the camera & equipment were removed from the PH Nest #2 and installed at the Sauces Canyon Nest where they were already incubating eggs.


The Seal Rocks Eagles used the same nest as last year ... so no cam there again this season.

The Eagles at the Twin Rocks Nest stayed with the same nest as last season ... and again the cam was not reliable.

There were also no online cams on the Middle Ranch Nest ... Pinnacle Rock Nest and Rattlesnake Canyon Nest

We were kept up to date of events happening at these nests .. all on Santa Catalina Island .. through the IWS Catalina Updates.

Separate threads .. one for each of these nests .. were started .. and relevant information was posted on them .. to make it easier to keep track of what was occurring throughout the season.


Information was also taken from the Northern Channel Islands IWS Updates .. and entered onto a new thread Northern Channel Islands Nests, Santa Cruz, Santa Rosa & Anancapa Islands.

This kept us up to date with events happening on the Cueva Valdez ... Malva Real and Pelican Harbor Nest on Santa Cruz Island, the Trap Canyon Nest and the Lopez Canyon Nest on Santa Rosa Island and the newly discovered Oak Canyon Nest on Anacapa Island.

Together with information on the other Non-Breeding pairs on SC at Fry’s Harbor ... Smugglers and Willows Anchorage.


This Season has been an interesting one ... with new nests discovered and changes in partners!

So here is a review ... in Alphabetical Order.

Find out all about the nests on the ... Meet the Adult Pairs thread.

We hope that ALL the Eagles ... Adults and Fledglings ...
Stay Safe ... wherever they may go.


Thanks to Dr. Sharpe/Eagle Guy, Steffani/eaglegal and all the IWS Crew for their photos and videos used in this thread.

Cueva Valdez ... aka Hazards Nest - Santa Cruz Island.

During February and most of March the IWS Crew kept checking to see if there was any activity at the Baby’s Nest .. it didn’t appear they were using it.

Then at the end of March observations of the pair suggested a visit to Hazards Canyon was warrented ... and success ... their new nest was discovered!

The number of eggs that were being incubated couldn’t be confirmed and it wasn’t until April 26th that the IWS Crew got their first clear view of a chick.

This pair have spent considerable time in the same harbor, sometimes together, sometimes apart for over a year now.

In April during his Helo Survey, Eagle Guy found a nest in the canyon .. in an area where there have been a lot of GPS points .. but it was not currently in use.

The IWS .. and all of us .. are hoping this pair nests next season.

......Nest Canyon


(Click on thumbnail to see full size)


At the end of February the IWS Crew were surprised to observe that incubation was already underway on this nest .. much earlier than last year.

There was another surprise .. a change of mate.

K-36 ... the papa of A-70 ... had been replaced by A-39 ... and it was the new male who was incubating the two eggs.

But on their next tour in early April the Crew discovered that the nest had mostly fallen away .. and when they checked they found the remains of what looked to be about a 2 week old chick and egg fragments in the nest wreckage.

Sad news for all of us.

Hopefully next season will be better for this new pair.

Malva Real .. aka Carl's Nest (was Grassland) - Santa Cruz Island.


K-11/male & A-35/female


Posted Image
Johnson's part of their territory.


In February, the IWS Crew discovered that K-11 had a new mate, but couldn’t confirm who the “lady” was.

At the beginning of March a new ground nest was discovered in the Pair’s territory. Although this nest doesn’t look like much, it is actually pretty comparable to the 2006 ground nest in this territory. It might even be more of a nest.

Posted Image

Two adult eagles, likely the Malva Real pair, were also observed flying in the vicinity of this nest so the IWS Crew were pretty excited about it.

They kept checking last year’s Carl nest and the ground nest .. and although the eagles were observed at both nests .. there was no nesting behaviour.

On his Helo Survey in April Eagle Guy was able to ID the new female ... It turns out she is A-35, the adult that spent a lot of time in Santa Barbara a couple of years ago.

Posted Image


This pair proved to be elusive most of the time that the crew searched their territory although Don did find them together in late April.

Posted Image


Hopefully they will settle down and nest next season.

MR - Middle Ranch Nest - Santa Catalina Island.


K-93/male & A-37/female

Posted Image
....... Nest Tree.


In February the search was on to see where this pair would nest .. the hope was they would use last year’s nest again.

As their eggs were laid later in the season last year the expectation was they would repeat this pattern, so Steffani was surprised in early March to spot the male in the incubation position .. so there had to be at least one egg on the nest. A few days later they were able to confirm there were two.

During the rest of the month the nest was checked regularly but it was difficult to tell how many eggs the adults were still incubating.

On Sunday, April 10th, it was confirmed that a chick had hatched and the wait was on to see if another was on it’s way .. but by April 12th there was still just one little bobble head in the nest bowl.

On April 27th’s Catalina Update, Steffani posted that the nests without cameras are usually checked twice a day, and all the chicks were thriving except for this chick.

They had been concerned about this one as a few days after s/he hatched they never really saw him/her being as active as a week-old chick normally is ... and when Dr Sharpe had checked the nest, the chick had very little energy even during feeding.

On April 22/23rd they could see nothing on the nest.

Steffani: “We have been checking daily but the nest has been left alone for very long periods of time and we do not see anything in the nest bowl anymore, so we assume the little chick died. We can't tell what happened but Pete thought that maybe it had an infection on its umbilicus from hatching and was simply not able to overcome. We had seen the parents bring food to the nest; however, for the most part, it was squirrels.”

The adults were seen on the nest tree ... but no longer on the nest.

Sad news ....

Hope next season will be better for this pair ... if they are still together.

K-93 is still hanging around the area ... but A-37 has been travelling and has been spotted at Point Mugu Naval Air Station near Oxnard, CA.

OC - Oak Canyon Nest - Anacapa Island.


A-21/male & A-11/female

.... The Nest


Another milestone!

At the end of March, a former IWS employee .. now a researcher on another project .. found a bald eagle nest on Anacapa Island

The pair is the former Yellowbanks pair on Santa Cruz. They are now the Oak Canyon Pair, so named because of their first nest.


The IWS Crew made a trip to West Anacapa Island in June to check on the nest .. which they knew had two eggs when first (and last) seen in March. They found the nest and there was a chick ... just the right age for banding!


Hatch Date: April ?, 2011


Banded: June 7/11 ... Wingbling Number A-75/male ... Official Name: Anacapa .... Banding ... More Photos


Posted Image


Fledge Date: July 1/11


Eagle Guy: "We now have successful nesting on 4 of the 8 Channel Islands and this is the first known nesting on Anacapa since 1949. We will have to monitor this bird entirely by its GPS transmitter because of the difficulties in getting to Anacapa."

Unfortunately A-75's GPS transmitter appeared to fail on June 12th! Then in July they received data, which confirmed he had fledged. His solar-powered transmitter had probably just been sitting in the shade too long.

The IWS Crew continued to monitor the fledgling by boat whenever conditions were favourable .. and until the end of July were still receiving GPS Data.

Remember the GPS packs are solar powered, so it is likely not getting enough sun .. and if A-75 has started spending time in the small cave that both Oak Canyon adults perch in to escape the swarms of gulls at Anacapa. There wouldn’t be a lot of sunlight getting to the power pack there!

PH - Pelican Harbor Nest - Santa Cruz Island.


K-10/male & K-26/female


Posted Image.......Posted Image.......Posted Image
... Original Nest........................... Nest #2.................................. Nest #3


(Click on thumbnails to see full size)


During September through to December 2010 both adults periodically visited their nest and did some nestorations ... but there was a big hole in it and we were all concerned that it was unsafe for both adults and any future chicks.

Early January 2011 ... only Ravens visited the nest.

Then on Janurary 19th, a new nest was found! So a camera was installed by the IWS Crew to observe any action on it.

Both adults continued to surprise us by showing up occasionally at the original nest, but there was no nesting action either here or at the 2nd nest ... so where were they?

Finally ... on February 27th the newest nest was found!

Eagle Guy “After two days of searching we finally found the newest new nest for the PH pair.

It is located in a pine about 1.5 km west of their original nest and over 7.5 km from the new one we recently put the camera on. It is in a remote area that has no good observation points, so we are going to have to rely on the adults' behavior to tell us what is going on while we view the nest from our boat.

Whilst this nest looks much better than the last two and seems to have plenty of support. As you can probably tell, there will not be a camera on this nest because of its location.

He had actually spooked the adults off the nest and he wouldn’t have seen it at all if they hadn’t started to fly around and vocalize .. so based on the adults behaviour he was pretty sure they were sitting on eggs. However they would probably not know when the chicks hatched until they saw the adults feeding them ... or even how many until banding day!

So, whilst we were delighted to know that they had a safer nest with eggs already laid ... it was sad to know that we couldn’t continue to watch our “First Family” online.

We were kept up to date with events on this nest by the SC Updates.

April 6th Dr. Sharpe did a Helo Survey and saw K-10 on the nest, knew from his posture there was young chicks .. but couldn't see how many. On April 9th he confirmed there was at least one.

During April and May the IWS Crew continued to monitor this nest by boat whenever conditions were favourable.

June 3rd .. it was time to go check the nest and band the chick/s.



Hatch Date: April 9, 2011 approx.

So .. if all goes to plan .. in 2012 we will once again be able to watch K-10 & K-26 online.

Thank you so much Bette you have made a lot of folks really, I mean REALLY, happy! :Hugs:

PR - Pinnacle Rock Nest - Santa Catalina Island.


K-65/male & K-56/female

........ PR Nest


This season the eggs were laid earlier. The first one on February 16th and the second on February 18th ... but on February 20th only one egg remained in the bowl.

They had apparently lost one and there was no way to know which one.

The adults continued to incubate their remaining egg and at the end of March the IWS were checking the nest pretty much every day waiting for it to hatch and were starting to get concerned.

Then one Sunday, when Dr. Sharpe checked the nest ... the egg was gone. :'(

Steffani continued to monitor the nest and both of the adults seemed to incubating but when they got up there was nothing underneath. As they had incubated for over 35 days, it seemed unlikely that they will lay eggs again this season. Checks were made weekly on the nest but it remained empty.


In May K-65 had a “dispute” with one of the SR adults and ended up having to swim ashore.

Posted Image


In July K-56, was spotted hanging out with a younger male, K-73 .. aka Wind .. one of the 2007 WE Triplets.

Posted Image

He visited the nest on July 12th.

So ... what happened to the older male .. and could this mean another switch in mates?

Maybe, we will see K-56 come back next breeding season and reclaim his female and his nest from K-73 ... just like Superman (K-01) did this year with K-51.

There's never a dull moment around :<<o>>: :<<o>>:

Observation Point ........................... Nest Tree

(Click on thumbnails to see full size)


Due to the PH pair moving to a nest that is inaccessible .. the camera and equipment was moved to this nest and became "live" on Tuesday, April 5th 2011.

The IWS Crew had advised us that A-27 had a new mate.

A-28 ... the papa of A-71 ... had been replaced by A-40 ... and their first egg was laid on March 3rd.

A second egg was laid .. actual date unknown .. during the week of March 8th to 15th .. but this failed to hatch and remained on the nest for a long, long time before disappearing from view.


Hatch Date: April 9/11 .... Happy Hatchday - Chick #1

February 15th ... The Seal Rocks nest has the first eggs of the season!!!

Both adults incubated the two eggs and we were all delighted when they both hatched. They were the first known bald eagle chicks to hatch this breeding season.

The SR eagles haven’t had a set of twins since 2007 and this is the first time at their current nest. All very exciting!


Hatch Dates: March 19/20th, 2011.

A-57 has long made Smuggler’s Cove her territory of choice.

In February A-58 wandered into her domain. They are likely fledgling-mates in the hack tower where they were released.

This looks like one of our newer pairs ... who have spent considerable time together this season ... and seems promising for next year. :X:

Trap Canyon Nest - Santa Rosa Island.


A-08/male & A-22/female


Posted Image
...... TC Nest.


(Click on thumbnail to see full size)


Late February ... a check was made on the Trap Canyon pair and their nest near Verde Canyon.

There was a camera on that nest .. not online .. IWS observation purposes only .. but it wasn't working. So a way had to be found to observe the nest without being seen by the eagles .. if that was possible!

Another visit .. and a bird was observed on the nest. Although it wasn't possible to see into the nest bowl the eagle's behaviour indicated that there were egg/s there.

Early April the IWS Crew visited the Island, and this nest, hoping for good news after the findings at the Lopez Canyon nest ... but while this nest was in considerably better condition, the outcome wasn't any better. It was empty.

The adults were around, and though not real defensive .. or showing protective behaviour .. they were unhappy with the human presence.

The crew verified that the nest was empty and there was no sign of eggs or chicks below it.

So this pair may have just taken this season off.

Hopefully next year will be a better season for the nests on Santa Rosa. :X:

TR - Twin Rocks Nest - Santa Catalina Island.


K-33/male & K-17/female


Posted Image
Nest is circled


(Click on thumbnail to see full size)


It was early March before the adults were observed incubating their two eggs.

This nest was the last one out of all 7 Catalina nests to lay eggs and therefore the last ones expected to hatch. Unfortunately the eggs were not viable and failed to hatch.

The adults would not give up though and continued to incubate the eggs for 10 more weeks.

It was May 25th before Steffani finally saw an empty nest.

Steffani: "Collecting the eggs was considered at one point but that would have required a great deal of climbing and we would have also had to scare off the adults in order to get to the nest and that would have been a huge disturbance, which could discourage them from breeding on the same nest (or same area even) next year, and we certainly don’t want them to stop trying."

So .. this is the second year that this nest has "failed" ... :X: that next season is a much better one for this pair.
