To understand why ... and how ... the eagles, on the Channel Islands off California, have wing tags, we have to go back in time .. to 1980 .. when the Bald Eagle Restoration Program started .... to reintroduce Bald Eagles to Santa Catalina Island.

The information for this introduction has been taken from a report, prepared by Dr Peter Sharpe and Jessica Dooley of the IWS, in 2001, for the US.Fish and Wildlife Service ... and it will explain why the eggs, even now, have to be removed and what ‘fostering’ really means and leads us into the ‘banding’ process when the eaglets are ‘issued’ with their ‘wingblings’

INTRODUCTION
In 1980, the United States Fish and Wildlife Service (USFWS) and the Institute for Wildlife Studies (IWS) initiated a program to reintroduce bald eagles to Santa Catalina Island, California.
Between 1980 and 1986, 33 eagles were released on the island from three different “hacking” platforms. While many of these birds matured and breeding pairs were established on the island, reproduction was not successful ... due to DDE levels ... these had been found to be inversely correlated with eggshell thickness.

Since 1989, the reintroduced population has been maintained through manipulations of eggs and chicks at each nest site and through additional hacking of birds.

Artificial eggs are substituted for the structurally deficient eggs laid by the birds affected by DDE. The adult eagles continue to incubate the artificial eggs while the removed eggs are relocated and artificially incubated at the Avian Conservation Center (ACC) at the San Francisco Zoo. Chicks that hatch from these removed eggs, or those produced by captive adults at the ACC or by wild birds, are then placed in the nests containing artificial eggs.

Continued hacking activities have also resulted in the release of an additional 19 eagles since 1991


Things have improved from those early days. Since 2005, the eggs removed from the nests, are now taken to the IWS' incubation facility, on Santa Catalina Island, and hatched there, instead of being sent to the SF Zoo. (Eliminating the travel to San Francisco has increased the hatching rate of the eggs by reducing the potential damage caused by the additional travel).
In 2007 two nests .. Pinnacle Rock and Seals Rocks ... were allowed to keep their eggs and both successfully hatched and fledged 2 eaglets each!
The IWS has not manipulated eggs or nestlings at any nest on Santa Catalina Island since 2008.

At the age of 8 weeks the IWS Team enter the nests and ‘band’ the eaglet/s ... these wingblings help to ID the eagles .. wherever they go.
The IWS monitor the movements of the eaglets through the radio transmitters in their back packs using traditional VHF telemetry.

In 2014 .. due to the lack of personnel to track the birds post-fledging .. the IWS discontinued the general use of all types of transmitters.

The wingbling numbers from previous Seasons/Years to the present date, together with some Questions and Answers about the wingblings, are listed below.

The following information about wingblings can be found on the “What are your questions?” Forum.
The dates of the questions/answers are listed in the ( ) below the information.


Colors and codes:
The Bird Banding Lab designates the colors and codes that can be used in different areas.

We are supposed to use light/powder blue wing tags with the letter "A" and a 2-digit number for birds released/produced on the northern Channel Islands. ( e.g. Santa Cruz Island)
Orange wing tags with the letter "K" and a 2-digit number (e.g. K-10) for birds on Catalina Island .

This is supposed to minimize the chances of birds of the same species in the same area getting similar wing markers. Unfortunately, a golden eagle study in the San Diego area also uses orange wing markers (with the letter "C") and juvenile golden and bald eagles are very similar in appearance. The supposed bald eagle that was being seen along the freeway earlier this year turned out to be a juvenile golden eagle from the San Diego area.
(Nov 29/06 & May 30/07)

We are assigned K-00 to K-99 for the wing markers on Catalina and A-00 to A-99 up north.
The eaglets also have leg bands attached at banding .. the leg band numbers aren't assigned, we just report them to the BBL.


What are they made of?
The wing markers are made of a vinyl covered polyester called Shelterite. They are very light and are folded over the front of the wing and attached through the patagium with a small stud usually used for putting eartags on piglets. There are few nerves and blood vessels in the patagium, so the attachment is quick and painless.
(May 30/07)


How Many?
We put tags on both wings, but over time they can degrade and tear, so the birds with one tag (e.g. 01 at WE Nest) likely still have a tab on their wings that is just covered by feathers.
(Feb 3/07)

Wray and Dianna ... WE Nest ... are both from BC and were released together from a hackbox on Catalina Island over 20 years ago.
Dr Sharpe trapped Dianna in 1997 or 1998, and put her wing markers ... 69 ... on then. Neither female had markers when they were originally released.
(Jul 30/07)


Do they bother the birds?
The wing markers are treated like feathers by the birds and we have seen no evidence that they have impacted the birds at all in the 17 years that we have used them. The birds do get leg bands, but those can only be read from about 50 m away with a powerful spotting scope and if the bird is standing just right. Because this is a managed population of bald eagles that would not exist without our help, it is important for us to know who each bird is and to get an idea of where they are taking up residence if they leave the island. The wing markers do eventually break down and fall off the birds.
(May 7/06)


How long do they last
They degrade after 10 years or so.

K-01 .. New male on the West End Nest. (First seen there on March 4/06.)
January 7/12. Eagle Guy's post on Nest Observations/Nest Watch after zooming the camera in on Wray's leg band. Confirmation it's her! :)^
January 18/12. Now we know the reason .. How Wray was named. .. Lady in the photo is Wray Ann Wong (Sweezey) .. February 5/12. Full Story
Catalina Island Update: September 25 - October 2, 2013. Last confirmed sighting of Wray on Oct 1/13 .. IWS Crew observed her for a couple of solid hours after the last bait drop.
Because Wray has no blings it is difficult to confirm if she is still in the area.

<::: :<<o>>: Tribute to Wray by Wings Haliaeetus :<<o>>:



N.B. Dr. Sharpe trapped Dianna on June 20th, 1997, and put her wing markers .. K-69 .. on then. Neither WE female had markers when they were originally released.

There were no eggs or chicks fostered into nests on Catalina Island this year. Therefore none fledged.

Also no chicks were released from hack towers on Catalina Island this year either.
