Hatch Timelines - What to Expect

Experience shows that the first egg often hatches around Day 38 and the second egg hatches a bit earlier than Day 38 as a result of the "cooling period" of the first egg thereby promoting a closer hatch of the eggs. Once all the eggs are laid then the birds generally incubate the eggs continuously. In 2014 Belle (NCTC Eagles) cooled the egg one night for 6 hours straight and we speculated it was because she had a third egg to lay, which turned out to be the case.

We look forward to another great season growing along side the Channel Island Bald Eagle families Wub and we look forward too and welcome your participation here hug


May you embrace all the "blessings and gifts" that surround you in your life ... let your spirit soar :-)

West End Family History - Thunder and Superman

Meet the resident pair K91 Thunder (F-Born 2009/Off spring from Two Harbors Nest) and K01 Superman (M-Born 2000) Wub

Collage by Debs



The West End Nest & Territory



Superman and Thunder - Family History

Superman K01 and Thunder K91 became a new pairing late in the 2014 season after the long term resident female Lady Wray went missing and presumably died of old age. See Wray's legacy and the entire history of the West End pairs on the next post!

As a new pair; K91 Thunder and K01 Superman did not produce any offspring in the 2014 season. In 2015 this pair had two eggs; one egg broke very close to hatch date; a dead chick was visible and K91 consumed its remains. Dr. Sharpe thought based on the size of the chick that it likely died sometime before the egg broke. The second egg hatched on schedule and this pair enjoyed their new baby chick. Sadly the chick died just after it was removed from the nest for banding. The death of the chick was a sad loss for this new pair and also for everyone following this family. The IWS crew were shocked; they had never lost a chick during banding so this was a very unusual event. A necrospy determined the chick died from acute septicemia a bacterial infection in the blood. We hope that the 2016 nesting season will go better for this pair.

2014 - New Pair; Non Nesting Season
2015 - Two eggs; One egg broke with a dead chick inside (very close to hatch time) Second Egg Hatched - April 5 2015; Sadly the chick died during Banding - May 28 - 7 Weeks of Age

Background on the Legacy of Wray & Superman & West End Pairs

Wray Goes Missing-Fall of 2013 - New Female(s) at West End

After the 2013 nesting season Wray appeared to be sporting an foot or leg injury as she was limping and favoring one side. I think the last time I saw Wray
in the nest was August 17 2013 although Dr. Sharpe reported seeing and observing her on October 1, 2014, from the bait station. Dr. Sharpe had set up
the bait station so that he could observe Wray and possibly trap her so that he could examine the nature and extent of her injury. Wray never did visit the
bait station in fact she disappeared during this same time period.

On October 22 2013 a young female K-87 started visiting with Superman at the West End nest. Over the next five months it looked like K-87 was going to
be the new resident female at West End then on April 5, 2014 K-87 was displaced by her sister K-91. Since then K-91 has been the steady female at the West End nest.
Unfortunately, all the change at the West End nest resulted in a lost breeding season; there were no eggs were laid in 2014!

Hard to say good bye to Lady Wray who had tremendous presence; a great teacher to her kids but also too so many of us observing her. Wray was a protective,
warm and loving mother to all her babies and always a fun loving partner to her Superman. We loved Wray's wit and charm in the nest ... miss her so much ...

Lady Wray ... May You Always Soar High & Forever Free ... RIP Wray ... Forever Loved ... Forever in our Hearts Red Heart


Wray & Superman - Family History - 2006 to 2013

1986 - Wray was born in British Columbia then taken to the Channel Islands & released from the Sweetwater Hacktower on Catalina Island. Resident female since 1991
2000 - Superman was born at the San Francisco Zoo then fostered into the Pinnacle Rock Nest; Replaced the resident male who disappeared in 2006

2007-Three fostered chicks - K72 (F) Earth; K73 (M) Wind; K74 (M) Fire; all three fledged successfully.
2008 - Two chicks - K-65 (F) Miracle (Westie); K-67 (F) Surprise both fledged successfully.
2008 - Note: Two eagles now have the same bling ~~ K65 Westie & K-65 (M) PR Nest-Class of 1986
2009- Two chicks - K98 Faith and K97 Joy - both female; both fledged successfully. K98 Deceased
2010- Two chicks - K08 Dakota and K07 Aquila; both fledged successfully. Deceased: K07 & K08 only K07's body recovered.
2011- Three chicks - K-12 (F) Aahana; K-13 (M) Alerio & K-14 (M) Prince Harry; all three fledged successfully. Deceased K14
2012- Three chicks - K-27 Athena (F) & K-24 - Megwich (M) & 5Z Ge-nii (F) - nicknamed Me2; all three fledged successfully; Deceased K24 & K27
2012 - Note Me2 was too small to get wing blings so she was banded with two bands like Superman; one silver band/left leg and one orange band/right leg
2013-Three Chicks - K27 (M) Newton; K28 (F) Bella; K29 (F) Marthe; all three fledged. Deceased K29 Marthe
2013 - In the fall Wray goes missing; presumed deceased from old age; she was 27 years old when she went missing.

Superman Goes Missing - Fall of 2010-New Male K51 Comes a Courting
After the 2010 nesting season towards the latter part of August Superman K01 disappeared from the area. Wray remained in her territory and
in September a new young male K51 started visiting the nest and began courting Wray. Over the course of the next four months and based
on the behavior observed in the nest it certainly appeared that Wray was accepting K51 as her new mate.
K51 was hatched at the San Francisco Zoo in 2005 and then fostered into the Pinnacle Rock Nest.

Then on January 13, 2011 Superman returned to the nest and he re-established his relationship with Wray. K51 left the territory and has not
been seen at the West End nest since but he has been observed with another female in the Channel Islands territory.

The Original Resident Pair was a Trio - Wray, Dianna and Shenandoah - 18 Years - 1991 to 2008

This nest was established in 1991 and it was a bit unusual as the resident pair was actually a trio of three adults; two females Wray, Dianna and a male Shenandoah.
In 1986 the Wray and Dianna K-69 were both brought to the Island as chicks from British Columbia, Canada and were released together from the Sweetwater Hacktower
on Catalina Island. The original male Shenandoah K-77 went missing in the spring of 2006
at 25 years of age. Superman K01 became the new resident male that same year. In 2008 Dianna K69 disappearedhas not been seen since 2008 but there is hope
she may have left to form a pair with an unattached male. According to Dr. Sharpe of IWS, Wray and the original male were a pair for a year before
Dianna joined them, so she was the junior member of the trio. This amazing trio raised many chicks over the course of their 18 years together.

Identifiers
Dianna K69 - Orange wing bling on each wing.
Wray - No blings; has a silver leg band
Superman K01 - Orange wing bling on each wing; only visible when his wings are fully spanned as the blings are tucked inside and under the wings.
Superman has a silver band on his left leg and an orange band on his right leg.

In 2007 three of the five eggs removed for incubation in 2007 hatched, and the trio successfully raised female K72 ("Earth" ) and males K73 ("Wind" ) and K74 ("Fire" ). One of two eggs removed for incubation in 2008 hatched (though it was out of position for hatching and needed assistance to break out of its shell), and Wray surprised everyone by laying a third egg after the initial two were removed - which actually hatched naturally, although Dr. Sharpe put the chances of an egg from that pair surviving to hatch at less than 5% because of the contamination in the area. Both the incubator chick K65 "Miracle" and the naturally-hatched K67 "Surprise" are female.

Egg Laying
Based on past experience, look for eggs in late February and early March, chicks in early April, and fledging from mid-June to early July.

Wing Blings, Banding
Eagles hatched, fostered or released from hacking towers on Catalina Island have orange wing tags with the letter K and two numbers;
the first number is often the year they were hatched - but as there are now more than 10 eaglets per year, the others will get unused numbers
from previous years, like K03 at Seal Rocks.
Eagles hatched, fostered or released in the northern Channel Islands (including Santa Cruz and Santa Rosa) have powder blue wing tags with the letter A.

Fledgling Survival Rates
The first year for a young juvenile or fledgling is a difficult one as they learn to hunt and fend for themselves. At one time it was thought that about
50 percent of first year juvies did not survive that first year now with more transmitters tracking fledglings they now believe that survival rates
are much higher. The IWS tracks their fledglings so we will include updated information where we can...thanks to IWS.

Screen capture by Mpmom

A-40 Resident Male

The resident male # A-40 (M) originally from the SF Zoo; Released from South Hacktower on July 2, 2005. A40's leg band identifier: 629-47391
Blue wing blings lost in January 2013 and September 2014.

As of January 12 2016 we can confirm A48 continues to be the resident female at this nest based on band identification.


Sauces History

In Progress

There has been several failed nesting seasons at this nest ... changes within the pairs and some bad luck resulted in these losses ... hopefully 2016 is better for this pair.

2015 - Nest failed; Egg(s) laid; eggs broke
2014 - Nest failed; Eggs laid in Feb; both eggs broke; second clutch attempt a month later resulted in one egg being laid; egg broke; nest failed
2013 - Nest failed; Two Eggs incubated Intruder arrived into their territory early March; On March 4 2013; A27 disappeared while defending her nest; The resident male A40 attempted to incubate eggs alone until March 7 but eventually he had to leave the nest and ravens swooped in and stole both eggs! A few days later a new female appeared at the nest A49 Cruz there was speculation that Cruz might be the new female a this nest. However, a few days later another female A48 joined A40 on the nest; A48 replaced A27 and is now the new female at this nest. Note A27 was later seen with A-68 hanging out together in the Baby’s harbor area ... A27 and A68 fledged a chick together in 2015!
2012 -Two chicks fledgled; banded June 8 2012 .. A-81 & A-82
2011 - One Chick fledged; banded June 2 2011 A-73 Note Change in pairing - In Feb 2011 the original male A28 was replaced by another male A40; A27 and A40 successfully raised and fledged one chick
2010 - One Chick fledged; Note A27 becomes the new female at this nest and together A27 and A28 successfully raised and fledged one chick
2009 - Nest failed; July 22 2009 resident female A02 deceased; body found in Pozo, CA
2008 - Nest failed; A28 male and A02 female become a pair at the Sauces nest
2007 - Non Nesting Season? - A02 and A28 paired up at the Sauces nest
