Falconry: Effects on raptor populations and management in North America","docAbstract":"The art of falconry in North America, practiced by a few individuals for many years, attracted little attention until the 1960?s. Presently about 2800 falconers are licensed in the United States with less than one half considered to be active. While interest in this art is expected to increase, we believe growth will be slow, probably 5 to 10% per year, due to rigorous demands on time and equipment required and restrictive regulations.....Many different species of raptors have been used in falconry. Presently 6 species are commonly used, especially the Red-tailed Hawk and American Kestrel. Present evidence suggests that only 2 races of the Peregrine Falcon are threatened in North America, and declines may have occurred in local populations of other species. Declines in populations of Peregrines are attributed to pesticide contamination of food chains. Apparent declines in other populations of raptors are also attributed to pesticides and locally to changes in land use and possibly indiscriminate shooting. Removal of raptors from wild populations for falconry has not had documentable adverse effects except possibly at local nesting sites. Continuation of the art of falconry under the framework of the recent federal regulations is not expected to have measurable impacts on region-wide populations. Management of raptors is poorly developed and relatively unexplored. Captive breeding of raptors holds much promise for production of birds both for re-establishment and as a source of birds for falconry. Falconers have contributed much to the continued improvement of the Cornell University Peregrine program in terms of breeding stocks and technique development.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wilson Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Braun, C., Enderson, J., Henny, C.J., Meng, H., and Nye, A., 1977, Conservation committee report.

Residues of 10 organochlorine pollutants and 10 heavy metals were found in these eggs. Total organochlorine residues were apparently magnified 23 times from fish to pelican eggs, but interpretation of biomagnification was complicated by the migratory habits of both the pelicans and their chief prey fish. Residues of organochlorine pollutants and heavy metals were also found in tissues of brown pelicans. Dieldrin was probably involved in the death of a pelican that exhibited myocardial necrosis. Other pelicans died from gunshot wounds, various diseases, or unknown causes. From 1969 through 1973, there was a significant decline in residues of p-p'-DDE, p-p'-TDE, p-p'DDT, and dieldrin in eggs of the brown pelican in South Carolina, but the rate of decline was different for each pollutant. PCB's peaked in 1972 and then declined in 1973 to the lowest level in 5 years. In 1973, the first time in many years, South Carolina brown pelicans reproduced very well.

One observer in each of 11 compartments counted marked and unmarked deer during 65-75 minutes at dusk during 3 counts in each of April and November. Use of radio-collars and vinyl collars provided a complete inventory of marked deer in the population prior to the counts. We sighted 54% of the marked deer during April 1987 and 1988, and 43% of the marked deer during November 1987 and 1988. Mean number of deer counted increased from 427 in April 1987 to 582 in April 1991, and increased from 467 in November 1987 to 662 in November 1990. Herd size during April, based on the mark-resight method, increased from approximately 700-1,400 from 1987-1991, whereas the estimates for November indicated an increase from 983 for 1987 to 1,592 for 1990. Given the large proportion of open area and the extensive road system throughout the study area, we concluded that the sighting probability for marked and unmarked deer was fairly similar. We believe that the mark-resight method was better suited to our study than the area-conversion method because deer were not evenly distributed between areas suitable and unsuitable for sighting within open and forested areas. The assumption of equal distribution is required by the area-conversion method. Deer marked for the mark-resight method also helped reduce double counting during the dusk surveys.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Birds","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Robbins, C., 1977, A comparison of 2 techniques for estimating deer density: American Birds, v. 31, no. 4.","startPage":"562","numberOfPages":"562","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":198516,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e48cee4b07f02db54551b","contributors":{"authors":[{"text":"Robbins, C.S.","contributorId":53907,"corporation":false,"usgs":true,"family":"Robbins","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":341935,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Seventeen were fed mealworms (Tenebrio molitor larvae) that contained 166 ppm DDE; the other five were fed uncontaminated mealworms. After 54 days of feeding, six dosed bats were frozen and the remaining 16 were starved to death. In a second experiment, 21 female big brown bats were collected in a house attic in Prince Georges County, Maryland. Sixteen were fed mealworms that contained 9.4 ppm Aroclor 1254 (PCB). After 37 days, two bats had died, four dosed bats were frozen, and the remaining 15 were starved to death. Starvation caused mobilization of stored residues. After the feeding periods, average weights of all four groups (DDE-dosed, DDE control, PCB-dosed, PCB control) had increased. However, weights of DDE-dosed bats had increased significantly more than those of their contols, whereas weights of PCB-dosed bats had increased significantly less than those of their controls. During starvation, PCB-dosed bats lost weight significantly more slowly than controls. Because PCB levels in dosed bats resembled levels found in some free-living big brown bats, PCBs may be slowing metabolic rates of some free-living bats. It is not known how various common organochlorine residues may affect metabolism in hibernating bats. DDE and PCB increased in brains of starving bats as carcass fat was metabolized. Because the tremors and/or convulsions characteristic of neurotoxicity were not observed, we think even the maximum brain levels attained (132 ppm DDE, 20 ppm PCB) were sublethal. However, extrapolation of our DDE data predicted lethal brain levels when fat reserves declined sufficiently. PCB-dosed bats were probably in no danger of neurotoxic poisoning. However, PCB can kill by a nonneurotoxic mode, and this could explain the deaths of two bats on PCB dosage.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Toxicology and Environmental Health","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor and Francis","doi":"10.1080/15287397709529491","usgsCitation":"Clark, D.R., and Prouty, R.M., 1977, Experimental feeding of DDE and PCB to female big brown bats (Eptesicus fuscus): Journal of Toxicology and Environmental Health, v. 2, no. 4, p. 917-928, https://doi.org/10.1080/15287397709529491.","productDescription":"917-928","startPage":"917","endPage":"928","numberOfPages":"12","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":269462,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/15287397709529491"},{"id":198761,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2","issue":"4","noUsgsAuthors":false,"publicationDate":"2009-10-20","publicationStatus":"PW","scienceBaseUri":"4f4e49cbe4b07f02db5d8271","contributors":{"authors":[{"text":"Clark, D.

Treated mealworms (Tenebrio molitor) containing 107 ppm DDE were fed to 17 bats; five other bats were fed untreated mealworms. After 40 days on dosage, during which one dosed bat was killed accidentally, four dosed bats were frozen and the remaining 17 were starved to death. The objective was to elevate brain levels of DDE to lethality and measure these concentrations. After the feeding period, dosed bats weighed less than controls. After starvation, the body condition of dosed bats was poorer than that of controls even though there was no difference in the amounts of carcass fat. During starvation, dosed bats lost weight faster than controls. Also, four dosed bats exhibited the prolonged tremoring that characterizes DDE poisoning. DDE increased in brains of starving bats as fat was metabolized. The estimated mean brain concentration of DDE diagnostic of death was 519 ppm with a range of 458-564 ppm. These values resemble diagnostic levels known for two species of passerine birds, but they exceed published levels for two free-tailed bats from Carlsbad Caverns, New Mexico.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Toxicology and Environmental Health","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor and Francis","doi":"10.1080/15287397709529623","usgsCitation":"Clark, D.R., and Kroll, J., 1977, Effects of DDE on experimentally poisoned free-tailed bats (Tadarida brasiliensis): Lethal brain concentrations: Journal of Toxicology and Environmental Health, v. 3, no. 5-6, p. 893-901, https://doi.org/10.1080/15287397709529623.","productDescription":"893-901","startPage":"893","endPage":"901","numberOfPages":"9","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":269461,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/15287397709529623"},{"id":199099,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"3","issue":"5-6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adce4b07f02db686365","contributors":{"authors":[{"text":"Clark, D.

Research has now shown that efficient production of enhanced images requires full utilization of both computer and photographic enhancement . procedures. Experimental photo-optical enhancement techniques carried out at the EROS Data Center (EDC) for a Landsat-1, 29 August 1972 scene, proved to be more easily interpreted for land classification purposes than the EDC standard color composite. I.f digital processing can be minimized by using photographic enhancement techniques, then costs of enhanced products could be greatly reduced. &nbsp;Perhaps one of the major objectives of computer processing of Landsat data should be to produce high quality cosmetically enhanced (eliminate striping and line drops) data which has a range of digital values that can be completely recorded by film media. If digital processinq can distribute reflectance data throughout the entire recording ranqe of photographic film, then photographic enhancement techniques could be employed cheaply by users familiar with the type of information they wish to extract from the imaqery. &nbsp;Alternatively, if custom enhanced imagery is to be produced for users not having a photographic capability, different enhancements may be tried in an iterative fashion in the photographic laboratory, without having to reprocess digital data in the computer for each iteration.

Researchers used banding, localized studies, aerial surveys, and pesticide analyses to identify factors influencing regional populations.  Declining populations showed extremely poor production, contamination by environmental pollutants (including DDT and its metabolites, dieldrin, and polychlorinated biphenyls) and thin-shelled eggs.  Following the reduced use and eventual ban of DDT and dieldrin, productivity began to improve.  Improvement in affected populations, mainly those along the Atlantic Coast and in the Great Lakes region, began in the late 1960s and is continuing in the 1970s.  Most populations in the South Atlantic region, in Western North America, and in Florida and the Gulf of California appeared to be producing at normal or near-normal rates in the late 1960s and early 1970s.  Although some of the most severely affected populations are still not producing at normal rates, the pattern of improvement and an increase in management activities, including provision of nesting platforms and establishment of Osprey management zones, allow cautious optimism about the future of the species in North America.  With its low recruitment potential, however, recovery will be slow.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"World Conference on Birds of Prey, Vienna, 1-3 October, 1975.

On sampling days, occurring at 2 to 3 week intervals, a formalin solution was applied to thirty O.25m areas in heavjly, commonly, and rarely used woodcock covers (5 samples/type of feedjngcover/study area). The extent of cover usage was based on use of vegetation by 51 radio-equipped woodcock, 1970-73 (605 woodcockdays). A total of 2,546 earthworms of nine species was collected; species and age compositions of collected lumbricids were similar on both study areas. Similarly. number and biomass (dry weight) of earthworms extracted did not differ significantly between study areas. However. the number and biomass of sampled earthworms were directly and significantly related to the intensity to which woodcock used covers. Those diurnal covers most heavily used by woodcock sustained the highest lumbricid populations, ostensibly because these covers provided earthworms with preferred foods (i.e., leaf litters) and optimum soil moisture-temperature conditions. In terms of earthworms and woodcock supported per unit area, management of second-growth hardwoods appears more efficient than attempting to alter coniferous or mixed forests.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of the Sixth Woodcock Symposium, held at Fredericton, New Brunswick, October 4, 5 and 6","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"[University of New Brunswick]","publisherLocation":"[Frederiction, New Brunswick]","collaboration":"OCLC: 37723545","usgsCitation":"Reynolds, J., Krohn, W., and Hordan, G., 1977, Earthworm populations as related to woodcock habitat usage in Central Maine, chap. <i>of</i> Proceedings of the Sixth Woodcock Symposium, held at Fredericton, New Brunswick, October 4, 5 and 6, p. 135-146.","productDescription":"iv, 198","startPage":"135","endPage":"146","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201178,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a50e4b07f02db628ab5","contributors":{"editors":[{"text":"Keppie, Daniel M.","contributorId":112999,"corporation":false,"usgs":true,"family":"Keppie","given":"Daniel","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":506010,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Owen, Ray B.

The multi-factor pollution of Chesapeake Bay has resulted in diminution of submerged aquatic plants and consequent change in food habits of the canvasback duck.  Although dredge-spoil operations can improve wildlife habitat, they often result in its demise.  Pollution of estuaries also affects birds directly, through chemical toxication, which may result in outright mortality or in reproductive impairment.  Lead from industrial sources and roadways enters the estuaries and is accumulated in tissues of birds.  Lead pellets deposited in estuaries as a result of hunting are consumed by ducks with sufficient frequency .to result m large annual die-offs from lead poisoning.  Fish in certain areas, usually near industrial sources, may contain levels of mercury high enough to be hazardous to birds that consume them.  Other heavy metals are present in estuarine birds, but their significance is poorly known.  Oil exerts lethal or sublethal effects on birds by oiling their feathers, oiling eggs and young by contaminated parents, and by ingestion of oil-contaminated food.  Organochlorine chemicals, of both agricultural and industrial origin, travel through the food chains and reach harmful levels in susceptible species of birds in certain estuarine ecosystems.  Both outright mortality and reproductive impairment have occurred.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Estuarine Pollution Control and Assessment,  Proceedings of a Conference held February 11-13, 1975","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"U.

The Moosehorn National Wildlife Refuge contains areas which are characteristic of the abandoned farms now being purchased for recreation or retirement as well as areas suitable for commercial forest management. Woodcock management, beginning in 1973, has centered on rejuvenation of diurnal habitat and creation of summer fields and singing grounds. Strips (10 mwide, 25 to 125 mlong and separated by 40 m) were clear~cut in two alder (Alnus sp.) stands resulting in increased diurnal use in at least one cover, increased singing male use and good alder regeneration. Small clear-cuts (30 X30 m) in a large contiguous woodland (1200 ha) with a history of few singing males resulted in an increased number of singing males despite an overall decrease in the number of singing males throughout the refuge.

Woodcock hens utilized young, second-growth forest stands which were similar in species composition for both nesting and brood rearing. A multi-varIate discriminant function analysis revealed a significant (P< 0.05) difference, however, in habitat structure. Nest habitat was characterized by lower tree density (2176 trees/ha) and basal area (8.6 m2/ha), by being close to forest openings (7 m) and by being situated on dry, relatively well drained sites. In contrast, woodcock broods were located in sites that had nearly twice the tree density (3934 trees/hal and basal area (16.5 m2/ha), was located over twice as far from forest openings (18 m) and generally occurred on damp sites, near (8 m) standing water. Importance of the habitat features to the species and possible management implications are discussed.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of the Sixth Woodcock Symposium, held at Fredericton, New Brunswick, October 4, 5 and 6","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"[University of New Brunswick]","publisherLocation":"[Frederiction, New Brunswick]","collaboration":"OCLC: 37723545","usgsCitation":"Bourgeois, A., 1977, Quantitative analysis of American woodcock nest and brood habitat, chap. <i>of</i> Proceedings of the Sixth Woodcock Symposium, held at Fredericton, New Brunswick, October 4, 5 and 6, p. 109-118.","productDescription":"iv, 198","startPage":"109","endPage":"118","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201185,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b23e4b07f02db6ae04f","contributors":{"editors":[{"text":"Keppie, Daniel M.","contributorId":112999,"corporation":false,"usgs":true,"family":"Keppie","given":"Daniel","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":506017,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Owen, Ray B.

Woodcock were reported in Oklahoma in all seasons and were most Jrequently sighted from 11 October to 10 January.  The peak in fall migration occurred between 11 November and 10 December.  Woodcock were found in 5 major areas across the eastern two-thirds of the state but 57 percent of the birds reported during the study were in the eastern one-third. A total of 148 displaying males were encountered on 25 sites in 15 of 29 counties included roadside singing ground surveys in 1975 and 1976.  The peak number of displaying birds (58) was observed during the second IO-day period in February; displays occurred from January through late March.  Personal observations plus data reported via volunteer survey cards, indicated that the typical site used for diurnal cover by woodcock in Oklahoma is a brushy bottomland with moist loamy soils, vegetated by oaks (Quercus spp.), elms (Ulmus spp,), bluestem grasses (Andropogon spp.), dogwoods (Cornus spp.) and green briars (Smilax spp.).","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of the Sixth Woodcock Symposium, held at Fredericton, New Brunswick, October 4, 5 and 6","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"University of New Brunswick","publisherLocation":"Frederiction, New Brunswick","collaboration":"OCLC: 37723545","usgsCitation":"Barclay, J., and Smith, R., 1977, The status and distribution of woodcock in Oklahoma, <i>in</i> Proceedings of the Sixth Woodcock Symposium, held at Fredericton, New Brunswick, October 4, 5 and 6, p. 39-50.","productDescription":"12 p.","startPage":"39","endPage":"50","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201186,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a5fe4b07f02db63488e","contributors":{"editors":[{"text":"Keppie, Daniel M.","contributorId":113918,"corporation":false,"usgs":true,"family":"Keppie","given":"Daniel M.","affiliations":[],"preferred":false,"id":506019,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Owen, Ray B.
