Condor Update as of November
5, 2005: Condor 350, last year's Battleship chick, now wears
transmitters as well as wing tags marked "-0" (since "50" is already in use by Condor 250).
After capture and tagging last week, on Wednesday Nov 2 he or she was still at Vermilion Cliffs feeding and socializing
with other condors, a very good sign. 350 had been up to the release site 4 times before Peregrine Fund biologists
made any attempt to capture him/her. |
First condor chick hatched in
the wild in decades is found dead

Condor Update as of March 7, 2005: Releases and AZ Population News: South Rim Information: Many thanks to Chad Olson and Thom Lord for keeping
us up-to-date. |
Condor Update as of November 4, 2004: California has had the first successful fledging of a wild chick since 1982! Here's the description of #326's first significant flight, written by Dr. Allen Mee on Nov 1: "Finally after what seems like months (ok
weeks) of waiting for a dramatic first flight that was never going to happen, it seems like we finally have a fledged
chick in California!!!! The date of fledging is pretty arbitrary as the chick left (slid/fell) the immediate nest
area on Oct 10th and moved about on this vegetated strip below the nest cliff over the next 2-3 weeks. It fell
further down the next tier of cliff on Oct 28th after being joined by a 2 year old condor (#277) but made its Highlighted numbers from the Nov 1 stats: World
total is still officially 246. (#300/tag 00 is still unaccounted for in AZ as is one of the wild birds in Baja,
but one hopes they will re-appear.) AZ wild population is now at 49, since three of the six remaining one-year-olds
were released from Vermilion Cliffs on October 16 (#291/tag 91, #293/tag -3, #316/tag 16). Our 49 wild condors
= 44 flying + 3 being held at V.C. + 2 nestlings. |
Condor Update as of October 1, 2004: They've finally officially given up on #176, missing
since February, which brings the worldwide total down to 246 and the total wild population in this area down to
46. That gives us 41 free-flying condors plus 2 nestlings plus 3 birds being held temporarily in the flight pen
at Vermilion Cliffs. Other changes: 6 birds were released at Big Sur on September 25, bringing CA's wild population
up to 51. It'll soon be 57 if all goes well, since there is a release of 6 condors from Pinnacles National Monument
scheduled for October 15. And the AZ population will jump to 49 on October 16 (if things go as planned), when 3
of the 6 remaining one-year-olds are released from Vermilion Cliffs. That's #291 (tag 91), #293 (tag -3), and #316
(tag 16). |
Condor Update as of September
4, 2004: Total Population: 247, (down one due to death of one wild chick in CA.) |
Grand Canyon Condor Update as of August 7, 2004 Last year's chick, the famous #305, is no longer
lacking in accessories. He or she finally made it to Vermilion Cliffs and was trapped, given tags marked 05 plus
one radio transmitter and one GPS satellite transmitter. S/he was inoculated against west Nile virus, a quick field
blood test was done to check for lead, and a blood sample was taken to be sent out for DNA analysis. (As you can
tell, the results are not yet in so the sex is still unknown!) Lead levels were somewhat elevated, so 305 was held
for a few days but has now been released. |
Grand Canyon Condor Update as of June 10, 2004 From Chad Olson of Grand Canyon National Park,
regarding the Battleship nest here in the park, where an egg is believed to have been laid around March 24-26: |
Grand Canyon Condor Update as of May 15, 2004 Unfortunately the May 1 stats still are not out!
So depending on how many eggs have hatched in captivity and at Vermilion Cliffs, the total world California condor
population might be anywhere from 222 to 250! The 222 figure includes the 218 population as of April 1 plus one
egg that hatched May 9 at the Oregon Zoo and 3 that hatched in the wild in California. |
Grand Canyon Condor Update as of April 9, 2004 The April 1 Condor Stats are out. Eggs are starting
to hatch in captivity, so the world total was up to 218 and may be higher by now. |
Grand Canyon Condor Update as of March 26, 2004 The release of four one-year-old condors from Vermillion
Cliffs on March 20 brings the total number of wild condors in AZ to 45! (Two of those are being held temporarily
in the flight pen, however, to prevent them from jeopardizing the nesting success of #114 and 149. Plus there are
6 youngsters in the flight pen still awaiting release.) In CA there are 44 wild birds, and in Baja there are 5.
World population still stands at 215 as far as I know. |
Grand Canyon Condor Chick Update 25 Nov 2003 The chick is doing well! Update from Sophie Osborn's
Notes From the Field as of Nov 20: Thus far, Condor 305 is doing extremely well. It
has made it through its first two weeks post-fledging and is taking more and more frequent flights (the longest
being about 300 meters). It consistently roosts on the safety of the redwall cliff. Although, it has not yet mastered
sufficient flight skills to soar or gain much altitude, it continues to make daily progress. |
. More California Condors To Be Released In Park Area
|
November 21, 2001 TWELVE CALIFORNIA CONDORS GO TO GRAND CANYON AREATwelve California Condors will be transported to a new home on public land on
Arizona’s Vermilion Cliffs, near the Grand Canyon, on November 27, 2001. Eleven of the condors hatched
this year at The Peregrine Fund’s breeding facility in Boise, the other is a female that hatched in 1999
and was brought back into captivity on April 11, 2000 due to her interaction with humans. Biologists have been
observing this condor in captivity for over a year and a half and now feel that she is ready to be re-released.
