2017 Nesting Season

8 eggs were laid over two clutches but unfortunately all 8 eggs broke.

First Clutch - Eggs laid on Jan 31, Feb 3, Feb 6, Feb 9 and Feb 12, 2017 - 5 eggs in the first clutch
Second Clutch; Eggs laid on March 3, March 9 and March 12, 2017 - 3 eggs in the second clutch

Dr. Sharpe posted this on IWS
"As have many of you, we have been intently watching the Bald Eagle pair at Sauces Canyon on Santa Cruz Island. We are disheartened to see that the most recent eggs broke yesterday.
We do not know why the eggs keep breaking, but will continue to monitor the nest and further investigate the cause. We will attempt to collect prey samples and eggshell fragments and analyze them for contaminant levels and eggshell thinning. Although this is an unfortunate situation for this pair, we are encouraged by their successful nesting in 2016 and the continued recovery of the Bald Eagle population across the Channel Islands. Thank you to all the dedicated web cam viewers for your observations and concern for the pair.

Sauces History

There has been several failed nesting seasons although the cause is unknown we have to wonder if pollution is a contributing factor.

2017 - 8 Eggs laid over two clutches all broke; thin egg shells could be the cause.
2016 - Two chicks; both fledged; A62 & A63
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

Posting Guidelines

We welcome all observations and discussions about eagles here and we ask all members to treat each other with mutual respect.

For continuity please use this video symbol to introduce your video Video Camera and the fish symbol Fish: to identify a fish delivery.

This is an international discussion thread and courtesy to others is expected. Be respectful and polite and refrain from comments about politics, race or religion or sexual innuendo.
Profanity, personal jabs or slams, or other inappropriate comments are unacceptable and will be deleted.

Please keep bold and color text to a minimum.

Please do not share animated or altered screen captures here.

As a courtesy to others here please do not use smilies in the body of nest observations and do not use ALL CAPS for your posts. We prefer that the Quote Button is not used on this thread...and if you must use it...because you are referring to something on a previous page...then take TEXT only...never captures or video; Thanks.

This thread is devoted to documenting the behavior of the eagles; discussion about non-eagle topics is fine when activity on the nests is slow.

Please limit the pictures in each post to no more than a total of 150,000 bytes (150KB) and to avoid horizontal scrolling pictures or scaps (screen captures) may not exceed 500 pixels wide - though it's fine to post a 500-pixel-wide thumbnail that clicks to a much larger picture. Three captures per post is recommended.

Periodically we will tidy up this thread by deleting posts that are not directly related to maintaining an accurate journal of nest observations and/or eagle discussion.

Enjoy the eagle watching and thanks again to all that participate by sharing nest observations, screen captures, reports from the ground and video footage on this open forum.

History of the Channel Islands Bald Eagle Restoration Project
as per the Institute for Wildlife Studies Web Site

In 2002, funding provided by the Montrose Settlements Restoration Program allowed IWS to begin a five-year feasibility study to determine if bald eagles could be successfully restored on the northern Channel Islands, California. The project objectives were to release 12 bald eagles per year on Santa Cruz Island (hereafter Santa Cruz) by hacking and then to carefully monitor the eagles' movements, forage use, and survival. Forage use and analyses of prey samples are to be used to evaluate the potential source of organochlorine contaminants that could affect the establishment of a self-sustaining bald eagle population. Santa Cruz is located approximately 20 miles off the coast of Ventura and Santa Barbara counties. Santa Cruz is the largest of the eight California Channel Islands, measuring about 38 km in length and 12 km wide at its widest point. The National Park Service (NPS) owns and manages the eastern 24% of the island and The Nature Conservancy (TNC) owns and manages the western 76% of the island.

Since June 2002, IWS has released 63 young bald eagles from two hacking (release) towers located on the NPS portion of Santa Cruz. Each tower has two cages, each of which can hold up to four young eagles being prepared for release. The eaglets were produced by the Avian Conservation Center at the San Francisco Zoo or collected from wild nests near Juneau, Alaska when they were about 8 weeks old. The birds were kept in the cages until they were ready to fly at about 12 weeks of age. They were fed a variety of foods that they encounter once released and we monitored them using a closed-circuit video system to insure that each bird was eating and behaving normally.

When the birds were approximately 11 weeks old, we fit each bird with a combination satellite/VHF transmitter, light blue patagial wing markers, and federal leg band. The satellite transmitters record hourly GPS locations of the bird and then upload them to a satellite approximately every three days. We are then able to download the data and determine where the birds have been. You can follow the paths of some of these birds here.
When the birds were approximately 12 weeks old, we opened the release doors on each cage. It took up to two weeks for the birds to fledge from the towers. We continued to place food items in and around the towers to provide a known food source for the birds while they developed their flight/scavenging skills.

In 2006, two pairs of bald eagles successfully hatched one eagle chick each. These were the first known successful bald eagle nests on the California Channel Islands in about 50 years. One pair of these eagles was originally released on Santa Catalina Island in 2001 (Male K-10) and 2002 (Female K-26). The second pair was comprised of a Catalina male released in 2001 (K-11) and a female released on Santa Cruz Island in 2002 (A-04).

As of the end of 2009, there are estimated to be about 40 bald eagles on the northern Channel Islands (Anacapa, Santa Cruz, Santa Rosa, and San Miguel), including birds released on Santa Cruz, at least three Catalina-released birds, and a few unmarked eagles from the mainland.

Note: In 2014 the IWS discontinued the general use of all types of transmitters.

Posted 1/6/18 on the IWS Facebook page:

"Our webpage with the live nest cams is changing to http://www.iws.org/livecams.html to simplify and make it easier to share. We have expanded from cameras on just bald eagle nests to include a peregrine falcon nest on Anacapa Island (hopefully will be used in 2018) and will soon include a new camera from a red-tailed hawk nest at the Presidio in San Francisco. It sounds like progress was made today with an internet connection to Santa Cruz Island, so we hope to have the Fraser Point and Sauces eagle nests back online in the near future. The former webpage (www.iws.org/interactive_nestchat_allUstream) will remain active until we have it automatically rerouted to the new page for all of you that have it bookmarked."

The Sauces Pair visited their nest just before dark ... so hoping they have a better year.

They both look healthy as they work on their nest; here is a video of clips of their visit.
