CALIFORNIA CONDORS in MONTEREY COUNTY
-- a discussion by Don Roberson
The prehistoric California Condor Gymnogyps californianus
-- one of the world's great birds -- is back in the skies of Monterey County.
The last wild condor in Monterey County was back on 10 Dec 1980 when the
entire world population, centered around Mt. Pinos in southern California,
was on the brink of extinction. Eventually the last 27 wild condors were
captured in hopes of captive breeding, the final one in April 1987. The
captive breeding effort has been successful: the world population was over
80 birds by the time of the first releases of captive-bred condors in January
1992 at the Sespe Condor Sanctuary, Ventura County. By January 2000, there
were 53 condors back in the wild and another 105 in captivity.
Here in Monterey County -- where California Condors nested until 1905
-- the Ventana Wilderness Sanctuary, a private non-profit group which successfully
reintroduced Bald Eagles to the central coast, has been releasing captive-raised
condors since January 1997. The first four young birds released in January
1997 proved to be poorly adapted to the wild (one spent substantial time
curiously investigating humans at Esalen) and all were returned to captivity
in June. In December 1997 five different youngsters were released from
their hack site high above Big Sur in the Ventana Wilderness. Unlike the
first set, these had been reared by adult condors early in their life and
were less imprinted on people. Additional releases since then, including
six on 4 Mar 2000, brought the local population to 15 birds. All are currently
flying over the Santa Lucias.
Ventana Wilderness condors have flown 150 miles south to mingle with
condors released in the Sespe area. Southern California condors have also
flown north to Monterey County. On 11 June 2000, nine condors settled on
the roof of the Oliver observatory operated by the Monterey Institute for
Research in Astronomy (MIRA) on Chews Ridge in the Santa Lucia Mountains.
The MIRA caretaker, Ivan Eberle, took
these wonderful shots at MIRA during that event... the avian equivalent,
I suppose, of the discovery of a passing comet [photos © 2000 Ivan
Eberle, used with permission; all rights reserved]. These nine condors
were from the Sespe releases in southern California; after resting a bit
on the observatory they took off and flew south again; they were well south
of Monterey County again within a couple hours.
All released condors have wing tags (MTY releases have yellow, blue,
or orange tags so far) and each has a number on the leading edge of its
wing. You can see how these wing tags look in the flight photo at the top
of the page. It is difficult to determine color of the tag -- and particularly
hard to determine the number -- unless you get very good views through
a 'scope or you are fairly close. VWS would love to hear about any condors
if you can determine tag color and number. Many of the condors also carry
small antennae which are used to radio-track the movements of individual
birds.
At least one of the Ventana released youngsters has learned to follow
Turkey Vultures to dine on “wild” food, including at least two seal or
sea lion carcasses on the Big Sur coast . The foraging on dead marine mammals
is particularly poignant since the California Condor was first described
to science in 1792 by George Vancouver from a condor eating a dead whale
on the shores of Monterey Bay. You can keep up on the progress of the re-introduction
of condors in Monterey County at the Ventana
Wilderness Society's website; see especially the "Notes for the Field"
page for month-to-month updates.
Searching for MTY condors: The appearance of nine condors on
Chews Ridge was unexpected. For more regular spots to see condors in Monterey
County, try these sites (but condors move daily, and where they are changes
day to day);
-
A favored roost site is at Pfeiffer-Big Sur State Park. There are pull-outs
on Hwy 1 on either end of the bridge over the Big Sur River. This is just
south of the entrance to the park. Walk to the center of the bridge and
look back inland (east), north of the river, for the roost trees. There
are several trees often used by Turkey Vultures, and these are the ones
sometimes used by condors. [Beware that vultures can look "huge" when roosting
close to you... if you have any doubt you are looking at a condor, you
aren't]. One of the roost is right above the Big Sur Lodge. When using
these roosts, condors may not leave the trees until mid-morning, and often
return late in the afternoon. This tends to be a winter roost site only.
-
Highway One along the entire Big Sur coast is good from the vicinity of
Bixby Bridge south to Lucia. Watch for swirling groups of Turkey Vultures...
sometimes condors are with them. Or sometimes condors cruise the coastline
alone. When a dead seal or sea lion washes ashore, condors may feed on
the carcass for weeks. One such event in July 2000 was on a beach visible
from dirt pull-offs on Highway 1, just a half-mile north of the entrance
to Julia Pfieffer-Burns State Park (7.1 miles south of "Nepenthe" restaurant,
or a half-mile south of the paved parking lot labelled "Vista Point" that
has an outline of a Gray Whale painted on the pavement).
-
Andrew Molera State Park north of Big Sur (about a half-hour drive south
of Carmel). While birding the park (a fantastic site for vagrants and the
host of the Big Sur Ornithology Lab) keep an eye on the ridgeline to the
east of Highway One. Several lucky birders have seen condors soaring along
that ridgeline.
History of MTY condors: Some interesting facts about wild condors
in Monterey County:
-
The first California Condor known to science was described from the shores
of Monterey Bay in 1792.
-
Condors were once a regular part of the MTY avifauna. Nests were known
from the interior and condors were regular along the coast into the 1900s.
Jenkins (1906) reported seeing 8-10 roosting in tall redwoods along Villa
Creek 18 July 1904 (on the southern Big Sur coast). Pemberton & Carriger
(1915) saw a bird over Big Creek and report that a local rancher had seen
up to 10 at a carcass as late as 1910 in what is now the Los Padres NF.
There are two specimens from MTY from as late as 1918 (#California Academy
of Sciences, San Francisco). A few condors were regular visitors to southeastern
MTY until the late 1960s; up to 18 together had been seen in Cholame Valley
(Eben McMillan quoted in Roberson 1985). Even as the numbers of birds declined,
MTY remained within the expected range of wandering individuals, with 13
records from 1970-1980, all apparently of adults (Roberson 1985).
-
Seventeen Condor eggs were collected in MTY from 1859 to 12 Apr 1905, and
this collecting contributed to the extirpation of the local breeding population.
Nest sites were apparently in the Palisades area (now in Ft. Hunter-Liggett)
and along the ridge that forms the southeastern border of the county (Wilbur
1978).
-
Reports of MTY condor sightings from 1970-1985 that were judged “positive”
by the Condor Research Center or the by Roberson (1985) were: 25 Oct 1970
Cone Peak (P. Kinder), 28 Jan 1971 Pebble Beach (T. Robinson), 21 Mar 1971
Marble Peak (J. A. Rodgers), 22 May 1971 Cone Peak (P. Kinder), 28-29 Sep
1971 Cholame Valley (J. Edwards), early June 1973 Turkey Flat near Parkfield
(B. Walton), 22 May 1974 Lower Arroyo Seco Cr. (M. Crutcher), 22 Aug 1974
Smith Mt. lookout, near Bradley (C. Halle), 31 Mar 1975 Hunter-Liggett
(L. Sitton), 6 Sep 1977 Los Padres NF (T. Raley, seen from helicopter during
Marble Cone fire!), 31 Mar 1979 near Devils Canyon, Los Padres wilderness
(R. Phillips), 2 Aug 1980 (3 adults) se. MTY (F. Klouda) & 10 Dec 1980
Mt. Mars (J. Lopez). The Condor Research Center has on file another 9 reports
between 1970-1985 evaluated "neutral" and not included here (and a 1985
report listed in Roberson 1985 should be disregarded).
The "countability" of MTY condors: From a bird-lister’s standpoint,
of course, the captive-bred released birds are not “countable” condors.
Captive-raised birds are never "countable" under the American Birding Association
(ABA) rules, even those released back into the wild. However, there are
three chances to "count" Monterey County condors on your life list in the
future:
-
Be one of the lucky observers to have seen a condor in MTY before 1980....
-
One of the original wild condors taken from the wild in the 1980s is an
adult female known as "AC-8" [condor researchers have "names" for each
individual condor based on their data base designations]. In April 2000,
"AC-8" was released back into the wild near Mt. Pinos. Radio-tracking has
shown she has begun reusing her old routes -- she could travel to MTY someday.
Since she is a wild condor held temporarily in captivity (even though over
10 years!), she became "countable" under ABA rules once she regained normal
behavior (that occurred within hours of her release). Condor "AC-8" has
a blue wing tag on which is the white number 12. The
rest of condor cohort released with blue wing tags were young birds, so
right now she is the only full-adult condor with a blue wing tag. In summer
2000 she was in the Sierran foothills of Tulare County to which she commutes
regularly from her winter range around the Sespe refuge.
-
All local observers agree that should local nesting occur, first-generation
wild condors -- born in the wild -- would “countable” on one’s list. The
ABA Rules Committee has never addressed the question of reintroduced birds
in native habitat directly, but I believe, based on my 15 years as a member
of the ABA Rules Committee, that the approach would be very different that
to non-native birds introduced into non-native habitat. For
these exotic introductions, we require a minimum of 15 years of consecutive
nesting plus a population expansion into all contiguous acceptable
habitat plus a population explosion so large that it is unlikely
the species will die out in the future (thus California parrots have never
been "countable" -- populations are much too small and many species that
have escaped have died out naturally because they are not perfectly adapted
for our habitat, even though sometimes it takes decades for this to happen).
But none of these rules apply to native birds reintroduced
into native habitat, and, since we all wish to encourage these reintroductions,
first-generation birds born in the wild are "countable."
Whether "countable" or not, any California Condor is impressive to see
in the wild. We now again are lucky enough to have this experience in Monterey
County. Good luck in your search....
