Santa Catalina Island, CA and the active bald eagle breeding territories in 2010.


As you know All Eagles All The Time 2011/2012 is an Archival/History in Videos and Still captures showing the various stages throughout the year in the lives of the Eagles on the EagleCams at Pelican Harbor (PH) Nest & Sauces Canyon (SC) Nest ... on Santa Cruz Island and Two Harbors (TH) Nest & West End (WE) Nest ... on Santa Catalina Island.

The other confirmed nests on Catalina Island are at Middle Ranch (MR) ... Pinnacle Rock (PR) ... Rattlesnake Canyon (RC) ... Seal Rocks (SR) and Twin Rocks (TR)


You can find out who is who at each nest by visiting the
Meet The Adult Pairs thread.


Because we still want to follow the events happening on these nests without cameras .. separate threads will be opened for each nest .. and I will be posting the links to the Catalina Updates, written by Dr. Peter Sharpe and Steffani Jijon ... along with the photos taken by Steffani ... so that members can easily access the current information.



This is the thread for Rattlesnake Canyon (RC).

UPDATE RE K-80 & K-47


:clk: Catalina Update: Wednesday, January 4, 2012 :clk:

Steffani: Yesterday, we headed out to mount the new Rattlesnake camera on the nest tree.
This is what the area looks like and that's Pete up there climbing the tree (again!)

I made a short video of Pete working on the nest tree and then an empty RS nest.

Steffani: I checked on the Rattlesnake nest the other day but there were no eagle visits while I was watching. It’s good to know that our new camera and microphone work perfectly. It sure makes it easier to monitor this nest with the aid of the nest cam.

Checking the Nest



:clk: Catalina Update: Thursday, February 2, 2012 :clk:

Steffani: I am back from vacation and fully energized for this busy upcoming breeding season!

On the day after my return, I visited a couple of nests to check for any nesting activity and have been checking nests ever since. I am proud to announce that all SEVEN CATALINA NESTS are active! Just a couple of weeks ago, the eagles were kind of visiting their territories but now, they are in full on breeding mode.

Every pair is using the same nest they used last year but there has been a mate switch on one of our pairs .. at the PR Nest.


Rattlesnake Canyon.

This video is quite interesting, if you notice, near the end of the video the female is picking on something right below the camera. When I was watching, at first I thought she was picking on the cable but then she pulled a yellow string, which happens to be the skinny line Pete left on the tree so he can climb the tree at banding. Well, we may have to start all over again because she was quite adamant to remove it from her nest. I guess she doesn’t appreciate the human contribution to the décor of her nest!

:clk: Catalina Update: Wednesday, February 8, 2012 :clk:

Steffani: This week, we have been checking all the nests regularly hoping for the first eggs of the season to be laid … but nothing yet.

They are all engaged and dedicated nest builders and we have observed the pairs mating regularly so we know we have many eggs coming our way!

I’ve checked on Twin Rocks and Rattlesnake nests using the nest cams. The nests seem to be worked on, but whenever I check, no one is home.

Steffani: We have been checking the nests almost every day hoping to see those precious little white eggs laying in the nest bowls.

Neither Rattlesnake or Twin Rocks have laid eggs yet but we’re sure they will soon.

TWINS ON THE RC NEST!


:clk: Catalina Update: Wednesday, March 28, 2012 :clk:

Steffani: On Saturday, Pete checked on the Rattlesnake nest and after waiting for a little while he discovered that there were in fact two little chicks in the nest bowl.

Mom, K47, attempted to feed them but she ended up covering the poor little ones in a bunch of grass and gull feathers. It was pretty funny to watch because at one point she couldn’t even find their little heads so she could deliver some food.

Steffani: The Rattlesnake chicks are growing very fast as well!

Rattlesnake Chicks March 30th & April 2nd, 2012.



:clk: Catalina Update: Wednesday, April 11, 2012 :clk:

Steffani: All of the eight Catalina chicks are doing great and their parents are trying to keep up with their demanding appetites!

Last week I checked the Rattlesnake nest. This nest cannot be seen from the road but we do have a camera, a transmission and a receiver site, which is where I normally go, plug my monitor in and spy on the little ones.

Posted Image.......Posted Image

I checked them yesterday again and they were home alone and constantly picking at each other … As the chicks get older and bigger, they can be left unattended for longer periods of time but be sure at least one of the parents is perched near by!

Rattlesnake Chicks April 5th & 10th, 2012.



:clk: Catalina Update: Wednesday, April 18, 2012 :clk:

Steffani: Over the weekend, we experienced some storms and some very heavy winds. We noticed on the cameras that the parents were taking really good care of their chicks during this rough weather so there’s no need to worry about them but still, one does…

The Rattlesnake chicks are the second oldest on the island and also old enough to be left alone for longer periods of time. While I was watching them on Monday, I noticed that one of them was already trying to feed itself from some leftovers from the nest. Because it wasn’t getting enough, it started begging to its parent that was perched on a branch right off the nest. They sure are entertaining!

Posted Image.......Posted Image

Notice the difference in size and developmental stage between the two chicks. Even though they hatched just a couple of days apart they look so different. I have been observing continuous sibling rivalry between these two, but we’re hoping the little one “catches up” on its growth by the time we go band them because otherwise, all it’s going to get is a leg band and maybe wing markers but no radio… so eat up little one!

SAD NEWS .. CHICK LOST IN A WIND STORM!


:clk: Catalina Update: Wednesday, May 2, 2012 :clk:

Steffani: Last Wednesday afternoon and evening, we had a storm coming through and we experienced some serious winds. We didn’t go to the field on Thursday because gated roads close after a heavy rain so I was back nest-checking on Friday.

On my last update, I mentioned that we worried that one of the two chicks seemed to be developing at a slower rate than the other chick and we were hoping that it’d catch up by the time it was time for banding. So RC was the first nest I checked and as soon as I plugged my monitor in, I noticed there was something wrong…

This is what I saw ... The older chick was on the nest all by itself!

Posted Image.......Posted Image.......Posted Image

I waited for a few hours hoping to see one of the parents come to the nest or some indication that the little chick was either below the nest or buried somewhere in the fluff, but nothing. I immediately consulted with Pete, who was on the mainland in transit to the northern Channel Islands for a couple of weeks, and I asked him if I should go down there and investigate the missing chick.

The good thing about this nest is that it sits on a tall tree at the bottom of the canyon so hiking to the nest is possible to accomplish without the eagles spotting us until the very end, once we have arrived to the actual nest. The hike still starts at the ridge (at 1600ft) and it drops into a poison oak-covered drainage. As soon as I arrived to the nest tree I realized what must have happened…

As it turns out, the strong winds from Wednesday night had hit this canyon so badly that it knocked over huge trees in the area, including one adjacent to the nest. And the winds must have also blown the poor chick off the nest in the process.

I took some pictures to illustrate the damage and I hope they do it justice.

This is one of the trees about 50ft away from the nest ... Posted Image..... And this one is right next to it ... Posted Image

The nest is in the red square and the fallen trunk is in the orange circle.
Posted Image

Thinking positively, we are lucky the nest itself didn’t get blown off because the outcome would have been worse!

I checked back on the RC chick on Monday and there he was. Scaring me as he approaches the edge of the nest!

Posted Image.......Posted Image.......Posted Image.......Posted Image

I waited to see if the parents were around and one did finally come and perched on a snag near by.

REMAINING CHICK IS DOING WELL!


:clk: Catalina Update: Wednesday, May 9, 2012 :clk:

Steffani: Last week, Pete traveled to Santa Cruz and Santa Rosa Islands to begin banding the oldest chicks of the season. Meanwhile, I’ve been keeping an eye on the Catalina nests and making sure the parents are taking good care of their chicks.

The Rattlesnake chick is doing great as well. He/she has started displaying some grabbing and mantling of the food that’s being brought to him/her, which is perfectly normal behavior for a chick that age. We will be banding this chick on Friday, May 18th.

Here’s a nice close up of K47 She has been perching on this electric pole located right by the road for the past couple of weeks, a safe spot for tour buses to spot her and admire her.

UPDATE RE K-22!


:clk: Catalina Update: Wednesday, June 6, 2012 :clk:


Steffani: The Rattlesnake chick is next on the fledging list so we’ll be keeping an eye out for him this coming week!

Sometimes I arrive to the tower and find an empty nest, but that just means that K22 has started to branch out and therefore stepping away from the view of the camera. I wait for him to return to the nest and I even got to watch a prey delivery! They grow SO fast!

Posted Image.......Posted Image

Empty nest again! But if you look really closely you can tell he is perching on the upper, right corner
Posted Image.......Posted Image


I put together a video too, this eagle is particularly entertaining. He must like not having anyone else to share his food with like the rest of the Catalina youngsters!

K-22 HAS FLEDGED!


:clk: Catalina Update: Wednesday, June 13, 2012 :clk:

Steffani: I have been checking on the Rattlesnake chick. On Friday, I found him still on the nest but branching outside of the camera’s view.

On Tuesday, I checked him again and all I found was an empty nest. I went out to feed the birds and came back but it still hadn’t returned to the nest.

So… I hiked out looking for him. I could hear him vocalized deep in the canyon but I couldn’t see it. I also didn’t see the adults around.

This morning I headed out to check on him again and after a couple of hours it finally hopped onto a grassy area near the creek.
Can you see him?

Posted Image.......Posted Image

I waited to see him fly but it didn’t move from there, just kept vocalizing away.
Again, I didn’t see the parents around so I’ll be going back there again tomorrow and make sure the parents continue to care for their chick. K22 is about 11 weeks old and parents generally continue to feed them until around week 16 so they better keep fishing for this little guy!

The eaglet is in the circle, the nest inside the square and the arrow point to the snag they like to perch on.

CHECKING ON THE FLEDGLING!


:clk: Catalina Update: Wednesday, June 20, 2012 :clk:

Steffani: This week, we have been keeping up with the fledging eaglets at Seal Rocks and Rattlesnake nest. All three seem to be doing just fine.

Finding the Rattlesnake chick is a bit more challenging because their canyon is much more lush and there are plenty of places to “hide” under.

See the chick??? Me neither! But I know it’s in those trees and probably looking at me.

Posted Image

I watched this chick for several hours on Sunday and again yesterday, and I was glad to see it move around the nest area. He begged pretty much the whole time but the parents arrived eventually.

Posted Image.......Posted Image

Pete also checked on him last week and he got an even better picture!
Posted Image

And finally perched on his parents snag.
Posted Image


And speaking of the parents; over the weekend I got a call from the harbor patrol saying that there was a bald eagle in the water and they had sent a boat over to check it out. Minutes later they called me again and it turned out it was K47, the female from the RS pair that had gone the extra mile to get an extra large fish! Check it out!

Posted Image

She ended up completely soaked but I’m sure she didn’t mind if it meant gorging on such juicy fish!

FLEDGLING SOARING & EXPLORING!


:clk: Catalina Update: Wednesday, June 27, 2012 :clk:

Steffani: I have been keeping tabs on the already fledged eaglets from the Rattlesnake and Seal Rocks Nests.

The RC chick, as usual, is harder to find because of all the tall trees in his area but I did get to spot him at last. Can you?
It’s just a little black figure among the trees…

Posted Image

Ok, now through the scope.

Posted Image

The second time I visited RC, I found one of the adults perching near the nest and it was a while before I heard K22 begging for food.

As I was getting ready to leave, a couple of ravens perched near him and started harassing him… they are so daring!
