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


As you know All Eagles All The Time 2010/2011 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 ... 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).

Steffani: On Tuesday, I checked out Twin rocks and Rattlesnake but when I arrived at the site the nest was empty, and it remained empty until I left.

EGG .. CITING NEWS!


:clk: Catalina Update: Thursday, February 24, 2011 :clk:

Steffani: When I checked on Rattlesnake I saw one of the adults finally incubating.
Because of all the rain we haven't had access to the road where our RS receiver sits so I have just been watching through a scope from the ridge.

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

On Sunday, I visited them again to see if she, K47, had laid another egg but when the male K80, arrived, they switched and not once was I able to see the bowl much less one egg or two. The male is left to incubate while the female heads out to the ocean.

Posted Image.......Posted Image

Yesterday I checked them twice, in the morning and later right before heading home and I was finally able to confirm two eggs!

MARCH UPDATES


:clk: Catalina Update: Wednesday, March 2, 2011 :clk:

Steffani: I checked on the Rattlesnake nest as well and after a long time of staring at the screen, K80 finally moved around and I was able to see 2 eggs.

Checking on one could take about 20 minutes or 4 hours, one never knows.



:clk: Catalina Update: Thursday, March 10, 2011 :clk:

Steffani: Pete checked on the Rattlesnake nest on Thursday, and after about 2 hours of watching the monitor, the female finally moved away enough for him to see their two eggs.



Posted Image



:clk: Catalina Update: Wednesday, March 16, 2011 :clk:

Steffani: We have been checking on the Rattlesnake Nest a couple of times a week. They still have two eggs and hereís a video of their incubation.

Video by eaglegal: Rattlesnake Nest. Still Two Eggs!



:clk: Catalina Update: Wednesday, March 23, 2011 :clk:

Steffani: The Rattlesnake nest still has their two eggs as well. This particular nest is easy to check but sometimes it takes a while. Because the camera pretty much looks down onto the nest, whenever the adults roll their eggs, it is hard for us to see the entire bowl. It is on the switches that they ďlet usĒ see whatís underneath them.

Hereís a video of what Iím talking about and keep in mind Iíve edited many rolls out!

MAY UPDATE


:clk: Catalina Update: Wednesday, May 4, 2011 :clk:

Steffani: Here is a video of the Rattlesnake chicks. Lately, I have been spending longer periods of time checking them because they play this hide and seek game on me; they hide, I seek!
Also notice how they scare me by perching right at the very edge of the nestÖ those dare devils.



Video by eaglegal: Rattlesnake Nest. April 28 & May 2, 2011



:clk: Catalina Update: Wednesday, May 11, 2011 :clk:

Steffani: I have been checking on the Rattlesnake chicks twice a week as well and they are both doing fine.

Their banding date, along with the Two Harborsí chick, is not for a couple more weeks. Weíll let you know the exact dates as they get closer.




:clk: Catalina Update: Wednesday, May 18, 2011 :clk:

Steffani: We have also checked on the Rattlesnake chicks twice a week and we will be banding them next Tuesday.

UPDATES RE K-15 & K-19


:clk: Catalina Update: Wednesday, June 1, 2011 :clk:


Steffani: Iíve been checking on the other two active nests Seal Rocks and Rattlesnake

I wish I would be showing you a nice clip of them on the nest but guess what? The day after banding, the nest camera broke! We recorded some video on banding day and everything worked fine that afternoon, but the next morning we were getting sounds and a black screen! We donít know what the problem is but evidently is somewhere where we cannot fix, as it would be closer to the nest so from now on, we can only check on these chicks by hiking the ridges and spying on them from far away using a spotting scope.

Yesterday, seen from the opposite ridge.

:clk: Catalina Update: Wednesday, June 8, 2011 :clk:


Steffani: These are the Rattlesnake chicks at about 10 weeks of age.

:clk: Catalina Update: Wednesday, June 15, 2011 :clk:


Steffani: We have also begun checking on the Rattlesnake chicks more frequently as their time to fledge has arrived.

Last Friday
Posted Image

On Monday, I checked them again and only found one of them at the nest so I waited until the other one returned from its ďhidingĒ place from an adjacent branch.

Posted Image

Iím on my way to check on them again and find out if they have gone from branching to flying! If I see one of them fly Iíll try to get it on video and put it on next weekís update!

K-15 & K-19 HAVE FLEDGED!


:clk: Catalina Update: Wednesday, June 22, 2011 :clk:


Steffani: Another week has gone by and TWO more Catalina Eagles have fledged!

This time it was K19ís and K15ís time to take the plunge from their 30ft-tall tree into their luscious canyon.
They were both up on their nest last Friday morning, by Monday they were nowhere to be found. It took me two days to finally locate them both and I did not want to leave the area until I saw them fly in and out of the nest and getting fed by their parents.

Last yearsí RS chicks died soon after they fledged for unknown reasons, so this is basically K47ís and K80ís first time caring for fledglings and we want to make sure it all goes according to plan.

RS nest seen from the top of the ridge ... Notice parent perched on snag.


Posted Image.......Posted Image

This was yesterday. K19 flew from the bottom of the canyon and perched by the nest for the longest time. K19 begs a lot!

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

K47 finally brought him some food to the nest. After a while, K15 showed up from the bushes and fly right by me.

Posted Image.......Posted Image

I made a couple of videos from last week and the last couple of days. I split the video into two parts and itís still quite long but Iím sure all of you would enjoy watching the lives of chicks outside of the camera view.


Video by eaglegal: Rattlesnake Family. Part 1 June 16-21, 2011

Video by eaglegal: Rattlesnake Family. Part 2 June 16-21, 2011

This is K80 calling out to his family.

Posted Image

This is K15, after his ďlandingĒ you just saw on the video.

Posted Image

Like any young fledgling, they are having some issues with landing, but we know they will get better; itís just a matter of time. And because they are not experienced yet, we will be checking on them three times a week, just in case.

Have I mentioned they picked out a beautiful canyon on the island? Right below their nest tree thereís a running creek with many little waterfalls and lots of interesting riparian plants.

With water comes mosquitoes and poison oak so itís not so fun hiking through it but it sure is pretty!

We will do our best tracking them down and showing you the areas they like to explore because pretty soon they will leave those nests and we wont be able to monitor them so closely like we do through the nest cams.

CHECKING ON THE FLEDGLINGS!


:clk: Catalina Update: Wednesday, June 29, 2011 :clk:

Steffani: We have been checking on the other four fledglings on the island from the Seal Rocks and the Rattlesnake nests. They are all doing well, flying like pros now and exploring a bit further each day while still confined to their territory.

I took some pictures of places they like to perch while I watch them and hear them beg to their parents for food.

The Rattlesnake fledglings sometimes make me wait for hours because there are so many trees and bushes they could be ďhidingĒ under that I basically just have to sit at this one spot and scan and wait. They do eventually make an appearance.

This is K-47 and her son K-19

Posted Image.......Posted Image

This is K-15 on a Catalina Island Cherry tree ... And a couple of days later.

Posted Image.......Posted Image

These chicks have been the last ones to be named.
K-19 is Ho'ihoulala (hoe ee hoe lala; Lala for short). It means 'return of the branch.' Native Hawaiians considered a tree as an image for genealogy. This 'branch' was in danger of dying out completely. In future generations this particular species will be recognized as a symbol of triumph over extinction, with the help of man.

K-15 is Robben. It is a variant of Robert (Old German) and Robin (English), and the meaning of Robben is "bright fame". It is also associated with the robin, the harbinger of spring and a symbol of rebirth.

Here is a video of these two.

FLEDGLINGS STAYING COOL!


:clk: Catalina Update: Wednesday, July 6, 2011 :clk:

Steffani: Because eagles donít ďknowĒ holidays, on Monday, Pete headed out to SR to check on the youngsters while I went to the Rattlesnake area and checked on K15 and K19.

Their canyon has plenty of relatively tall trees and bushes that provide nice shaded areas for them to perch on, itís not ideal for finding them but Iím glad they can find places to stay away from the heat. Here are a few images for you

Can you see the eaglet?

Posted Image

Me neither! The eaglet flew behind that bush and I didnít get a chance to see who it was. Thatís why I had to wait until one of the parents arrived to the area, which encourages the youngsters to move to a more exposed area so I can read their tags.

Well, the bird never moved BUT the other one, who happened to be K19 (Robben), did appear from the opposite side and perched at the bottom of the canyon.

Posted Image.......Posted Image


K15 (Hoíihoulala) never came out of the bushes, but since I saw it fly into them earlier, that counts as a check!

FLEDGLINGS STILL AROUND!


:clk: Catalina Update: Wednesday, July 13, 2011 :clk:

Steffani: Another week has gone by and I am pleased to report that all eight fledglings are doing very well! None of them have left their territories yet, as their parents continue to care for them.

The other day I went on a 7-hour search for the Rattlesnake fledglings. I started up on the canyon so that I can have a wider view of the canyon.

Posted Image


After about an hour, one of the adults flew in to the area from the ocean and perched on a rock. K15 and K19 were vocalizing but didnít come out.

Posted Image.......Posted Image


I moved down to another observation spot where I can see the nest and a few roosting places really well but still no visuals.

Posted Image.......Posted Image


I kept moving down the hill and closer to the bottom of the canyon. They were getting louder but still no visuals. I circled the nest and the arrow is pointing to their favorite roosting tree right by the nest (which they rarely use nowadays)

Posted Image.......Posted Image


I know they are perching somewhere down there in those trees but they just wont tell me where!

Posted Image


I made a video of the search, no eagles to see in there but plenty to listen too.
