Restoration Technologies (PRT/QRT). The Surrogator™ is promoted by PRT/QRT as the “next generation in
game bird restoration”, and “proven to be the most effective means to restore quail and pheasant numbers.”
Game farm-produced, pheasant or bobwhite quail chicks are placed into the device (which acts as a brooder
house) at a few days of age and then are released at about 4-5 weeks of age.
The method employed in using the Surrogator™ is unambiguous—it is simple stocking of game-farm
pheasants and quail. That, of course, is the problem. Decades of scientific studies have shown that stocking
game farm birds is not effective in restoring and maintaining wild bird populations. Indeed, recent scientific
studies, including those with Surrogators™, have returned results showing that survival of liberated game farm
birds is so low that the practice is completely without merit (see the appended studies). PRT/QRT advertised
for a short time in PF and QF Magazines and websites some years ago. In fact, upon examining these
products and the methods they employ, we terminated our advertising and sponsor relationships with
PRT/QRT because of our commitment to wild upland game birds, habitat, and scientific wildlife management.
We do not endorse these products or their claims.
At PF and QF, we have only a small number of very well thought out operational policies for chapters to
follow—and, one of the most important is the prohibition against stocking game farm birds. The reason for the
restriction is very simple—this quick-fix, band-aid approach to upland bird restoration is not only ineffective, it is
inherently dangerous because of potential disease introduction and possible dilution of genetic diversity in wild
populations in the release area. Thus, our Mission at PF and QF remains focused on the proven methods that
do work—habitat establishment and management.
Pheasants (and Quail) Forever’s straightforward stocking policy was established over 20 years ago. It states
that “Pheasants Forever (Quail Forever) prohibits any form of stocking by chapters except monetary donations
to state wildlife agency-sanctioned programs for release of F1 generation or wild-trapped game birds into areas
of suitable habitat, or for state agency-sponsored research purposes.” The policy further “specifically prohibits
sponsorship with Pheasants Forever (Quail Forever) funds for stocking-before-the-gun programs, public or
private.” Stocking game-farm birds is a bad investment of funds that could be better employed for wildlife.
There are no long term benefits to be gained. We strongly discourage the use of all artificial means that rely
on release of game farm stock to restore or supplement wild populations of pheasants or quail. Chapter
purchase, sponsorship, or use of Surrogator™ units or others like them is not permitted.
We encourage our Pheasants Forever, and now Quail Forever chapters to continue their work in the manner
that has proven effective over 25+ years of successful operation. Please focus on the long term horizon and
invest your time, funding and effort in habitat preservation, establishment and management. That alone
remains the key to wildlife restoration.
Thank you so much for your selfless efforts on behalf of wildlife.
Recent literature on survival of pen-reared game birds released in the wild
Idaho (2009). Compared vital rates of two different (pen-reared and wild) ring-necked pheasant stocks and assessed
effects of predator control on these pheasants released into current range. Wild (31 males and 112 females) and penreared
(230 males and 1,059 females) ring-necked pheasants were released in spring into two areas in southern Idaho
during 2000–2001 to augment low resident populations. Wild female survival from 1 March-1 October was
significantly greater than that of pen-reared females in both 2000 (40% vs 4%) and 2001 (43% vs 8%). During 2001,
predators were removed within our study areas. Survival did not increase for either stock of female pheasants after
predator removal. Predator control did not increase the number of hens surviving to reach the nesting season (1
May), nesting rate or nest success. Wild female pheasants were seven times more likely to survive translocation to 1
October, ten times more likely to survive to the nesting season, eight times more productive, and one-third as expensive
per egg hatched than pen-reared females. Low survival, poor productivity and higher costs of spring-released penreared
female pheasants strongly suggest that this is an inappropriate management tool for increasing pheasant
numbers (Wildl. Biol. 15:80-88).
Nebraska (2008). The Surrogator™ captive propagation system is purported to significantly increase populations of
northern bobwhite and ring-necked pheasants. The units provide food, water, heat, and shelter for chicks until they are
released. Releasing pheasant chicks at 4-5 weeks and limiting contact with humans while they are in the Surrogator unit
is purported to allow the chicks to retain the survival instincts of wild birds. We evaluated the efficacy of the Surrogator
system by evaluating the survival and return-to-bag of pheasant chicks raised in the units placed on 2 shooting preserves
and 2 public wildlife areas. Survival from release until the start of the pheasant hunting season was low (12%) and annual
survival was less than 1%. Of the 170 pheasant chicks placed in the unit at the beginning of the study, 6 (3.5%)
were returned to bag (NE Game & Parks Special Report).
Georgia (2005). Private managed hunting plantation. A total of 1,641 five-week-old wing-tagged pen-reared
bobwhites were released using the Surrogate Propagation™ system during June, August and September; and 1,000
12-16 week old leg-banded bobwhites were “dump released” during November. Birds were liberated into intensively
managed pine savanna habitat that included supplemental feeding and predator control. A total of 93 birds were
harvested of which only 13 were wing banded Surrogator birds. In this study the Surrogate Propagation™ release
system alone did not result in the establishment of a sufficient number of “coveys” to meet the shooting
objectives of the landowner. In fact, when the land manager conducted an informal bird dog census during early
November, after the Surrogate Propagation™ releases, only five “coveys” were located. At that point the decision was
made by the landowner prior to hunting to supplement the population with more dump-released birds than originally
planned (Georgia DNR Special Study).
Kentucky (2007-2009). Study conducted by the Kentucky Department of Wildlife. In 2007, 294 birds were released
using the Surrogate Propagation™ system at a research farm. The farm was hunted hard during the 2008-09 season,
with no birds flushed or harvested. In 2009, KDW released 277 birds at the same site. Covey call counts were conducted
on the property during October; with 1 covey detected. In mid-November, 5 hunters using 5 dogs hunted 2 hours with no
birds flushed or harvested. At a second release site where no hunting was allowed, no birds were detected during Oct
covey call counts, flush counts, or in call back pens.
South Dakota (1990-92). Released 44 wild and 159 pen-reared hens on public lands with excellent habitat during April to
augment natural reproduction. Hens were followed for 181 days, through the nesting season, by radio telemetry. Only
8% of pen-reared hens survived the nesting season verses 55% of the wild hens. Predation accounted for 90% of penreared
hen losses. Pen-reared hens contributed little to nesting, because few lived long enough to hatch a nest. On
average 100 wild hens produced 34 broods, 100 pen reared hens produced 3 broods (J. Wildl. Manage. 58:501-6).
England (1982-85). Large releases of pen-reared hens in the fall of each year showed that pen-reared hens were 3x
more vulnerable to predation than wild hens, and that wild hens were 4x more productive then pen-reared hens (J.
Wildl. Manage. 52:446-450).
Iowa (1977-79). Released 2,510 hens on 3 study areas to increase populations. Subsequent analysis by winter flush,
roadside, and crowing counts showed no increase in local populations. Populations on the 3 study areas fluctuated
similar to populations on nearby areas that received no stocking (IA P-R Comp. Rpt. 16pp).
Oregon (1972-73). Released 335 pen-reared hens on public land in early April. Nearly all had disappeared within 40-50
days of release. Only 17 known young were produced from 335 pen-reared hens released. Wild hens (61) on the
area produced 378 young during the same time period (Northwest Sci. 50:222-230).
Nevada (1972-73). Released 60 birds in April to augment natural reproduction followed by radio telemetry for 80 days.
Recorded 63% mortality, 30% which occurred in the week following release. Most of the mortality 63% was due to
predators. None of the hens successfully hatched a nest.
Minnesota (1967). Released 74 hens and cocks in August and followed movements for 28 days by radio telemetry.
Sixty birds or 81% died by day 28. Mortality was mostly predation (55%) (J. Wildl. Manage. 34:267-274).
Illinois (1983-85). Wild bobwhite quail were shown by electorphoresis of blood samples to have greater genetic
variability than game farm stock. The lower genetic variability among game farm birds is likely related to inbreeding and
make-up of the founding game farm stock. Low survival and poor fitness of game farm quail may be partially
attributed to the loss of genetic diversity.
Tennessee (2002-03) Genetic assessment of pen-reared Northern Bobwhite releases on Ames Plantation
K. O. Evans, M. D. Smith, L. W. Burger Jr., R. Chambers, and A. E. Houston, and R. Carlisle. In response to low
encounter rates with wild northern bobwhites (Colinus virginianus; hereafter, bobwhites) during bird dog field trials at
Ames Plantation in Tennessee, a large-scale release program of pen-reared bobwhites was implemented in the fall of
2002. To evaluate potential genetic effects of pen-reared releases on wild populations, we monitored survival of penreared
and wild bobwhites from fall release of pen-reared bobwhites through the breeding season. We used genotypes
from 6 polymorphic microsatellite loci to measure genetic diversity and conduct population assignment tests. Genetic
diversity, number of alleles, and allelic richness were greatest in the wild, intermediate in the F1 generation, and lowest in
the pen-reared populations. In some years, some pen-reared birds will survive to the breeding season and successfully
reproduce with wild birds. Given that pen-reared and pen-reared x wild birds have reduced genetic variability relative to
locally adapted wild birds, large-scale releases of pen-reared bobwhites may result in negative impacts on the
genetic integrity of resident wild populations.
