Deer Movements in Relation to Food Supplies in the Southern Appalachians We studied seasonal movements of white-tailed deer (Odocoileus virginianus) in northeast Georgia in relation to agricultural food plots during years of varying oak (Quercus spp.) mast production. In total, 2,381 radio telemetry locations were collected from 12 does from 1987 through 1989. Fall and winter home ranges were larger (P < 0.1) during a high oak mast productivity year compared to a low productivity year. There were no differences (P > 0.1) in spring home range sizes under 3 different oak mast conditions. David M. Carlock, K. E. Kammermeyer, L. F. McSwain, E. J. Wentworth

Nutritional Quality and White-tailed Deer Use of Warm-season Forages We evaluated standing crop, nutritional quality, and use of 3 legumes planted to provide forage during summer, which is a nutritional stress period for white-tailed deer (Odocoileus virginianus) in southern Texas. Average standing crop of lablab (Lablab purpureus) from 861 to 2,250 kg/ha exceeded (P ≤ 0.05) that of soybeans (Glycine max) and cowpeas (Vigna sinsensis). Phosphorus (P) of lablab and cowpeas exceeded (P ≤ 0.05) soybeans. Lablab crude protein was not different from cowpeas and soybean crude protein, but soybean was greater (P ≤ 0.05) than cowpea in 1990. Nancy M. Beals, T. E. Fulbright, R. L. Bingham

Food Plots and Deer Home Range Movements in the Southern Coastal Plain Radio-collared white-tailed deer (Odocoileus virginianus; 7 males, 13 females) were tracked from 1984 to 1989 on the Marion County Wildlife Management Area in southern Mississippi. Alternating halves of the study area were planted with 66 0.1-ha and 20 0.4-ha cool-season and 20 0.4-ha summer agronomic forage plots. Mean annual production and utilization (air-dry) of cool-season forages were 1,904 kg/ha (SE = 59) and 1,107 kg/ha (SE = 41), respectively. Summer forage production and utilization were 664 kg/ha (SE = 50) and 586 kg/ha (SE = 48), respectively. Robert E. Vanderhoof, H. A. Jacobson

Comparison of Three Ladino Clovers Used for Food Plots in Northeastern Georgia We compared production, utilization, and protein levels of 3 ladino clovers (Trifolium repens) in northeastern Georgia. Three 0.2-ha clover plots were planted side by side in 2 separate fields on Chestatee Wildlife Management Area. Samples were clipped, weighed, and analyzed monthly for a 26-month period beginning in April 1990. All clovers were utilized very heavily by deer (Odocoileus virginianus) and other wildlife averaging 392 kg/ha per month dry weight totalling 10,210 kg/ha for the study. Kent E. Kammermeyer, W. M.

Habitat Characteristics of Bobcat Core Use Areas in Mississippi Sixteen adult bobcats (11 females, 5 males) (Felis rufus) were monitored using radio-telemetry from 1 January 1989-31 December 1992 in Mississippi to determine habitat components influencing core use area (CUA) location and size. Male bobcat CUA size (x = 26.5 km2, SE = 6.1) was larger (P = 0.047) than females (x = 11.8 km2, SE = 2.8). Habitat components of bobcat CUA's did not differ (P > 0.10) by sex. There was a higher (P < 0.01) proportion of pine plantations and agricultural habitats in CUA's than in random areas.

Techniques to Monitor Relative Abundance of Coyotes in East Tennessee Scent stations, passive hair-snaggers and howl surveys were evaluated as possible survey methods for monitoring relative abundance of coyotes (Canis latrans) in Great Smoky Mountains National Park (GSMNP) prior to the reintroduction of red wolves (Canis rufus) from January 1990 to April 1991. Scent station nights (N = 198), passive hair-snaggers (N = 70), and howl surveys (N = 197) produced 1 (0.5%), 0 (0.0%), and 35 (17.8%) coyote responses, respectively. Scent stations and hair-snaggers proved ineffective for monitoring coyotes at current population levels. Barron A. Crawford, M. R. Pelton, K. G. Johnson

Bobcat Prey Digestibility and Representation in Scats Nine bobcats (Felis rufus) trapped from the Coastal Plain of Georgia in fall 1989 were fed weighed amounts of cotton mice (Peromyscus gossypinus), hispid cotton rats (Sigmodon hispidus), eastern grey squirrels (Sciurus carolinesis), domestic rabbits, a juvenile feral hog (Sus scrofa), and adult white-tailed deer (Odocoileus virginianus) to develop correction factors to convert mass of prey remains in scats to an estimate of mass of prey consumed for different prey types. Dry matter digestibility increased with increasing prey size except for white-tailed deer. Leslie A. Baker, R. J. Warren, W. E. James

Reproductive Biology and Kitten Growth of Captive Bobcats in Mississippi We examined 8 years of data concerning female bobcat (Felis rufus) reproductive characteristics and kitten growth parameters. Estrus in adults occurred in February and March, peaking in February, while yearlings cycled later (Mar to Jul). Two litters/female/year was the maximum observed, although 3 estrous cycles were observed within a single breeding season. Recycling occurred 12-14 days following kitten loss. Gestation length averaged 64 days, with parturition occurring between April and May. Litter size ranged from 1-5 kittens (x = 2.3), with a sex ratio of 1.24 M : 1 F. Elizabeth D. Stys, B. D. Leopold

Territoriality and Pairbonding of Gray Foxes in Mississippi Spatial relationships of radio-monitored gray foxes (Urocyon cinereoargenteus) were examined over a 5-year period. Marginal overlap (<10%) of convex polygon home ranges of same sex adult foxes with adjacent home range boundaries provided evidence for territoriality. Extensive overlap was observed between juveniles and adults of opposite sex. Mean home range overlap of suspected mated pairs was 61% ± 13%, providing evidence of pair bonding between the sexes. Territory size (home range) may provide a useful measure of population density. Randy L. Tucker, H. A. Jacobson, M. R. Spencer

Wood Duck Nest Sites in an Old-growth Longleaf Pine Forest We determined the density and characteristics of natural cavities suitable for wood duck (Aix sponsa) nest sites in an old-growth longleaf pine (Pinus palustris) forest in Thomas County, Georgia, in 1991 and 1992. Of 17 suitable cavities found on the 72-ha study area, 6 had been recently occupied by nesting wood ducks. D. Clay Sisson, R. T. Engstrom

Variable Water Levels and Wood Duck Recruitment in Kentucky Recruitment in prairie duck populations is correlated with annual wetland conditions, but a similar relationship has not been demonstrated for wood ducks (Aix sponsa). Therefore, we studied the influence of variable water levels on wood duck recruitment at Sloughs Wildlife Management Area in western Kentucky during 1988 and 1989. In 1989, when water levels were higher (P < 0.0001), nest initiation was earlier, the nesting season lasted approximately 3 weeks longer, and mean brood sizes were greater (P < 0.05). Mark P.

The Relationship of Wood Duck Brood Density to River Habitat Factors To better understand habitat features on rivers that are important to wood ducks (Aix sponsa), I measured brood density for sections of 12 rivers (329 km) in Tennessee nightlighting during spring 1990 and 1991. Sixteen habitat variables were evaluated for each river and the relationship to brood density was tested. Brood density ranged from 0 to 1.8/km (x = 0.7 on unchannelized rivers). No broods were found on 61 km of channelized rivers.

Winter Foods of American Black Ducks and Mallards in Tennessee Primary foods of American black ducks (Anas rubripes) and mallards (A. platyrhynchos) wintering at Tennessee National Wildlife Refuge were compared by examining esophageal and proventricular contents of ducks collected during winter, 1990-91 and 1991-92. Seeds of natural plants comprised the primary component of the diet of both species. Nodding smartweed {Polygonum lapathifolium), wild millet (Echinochloa crusgalli), lovegrass (Eragrostis hypnoides), and rice cutgrass (Leersia oryzoides) were the most common seeds consumed by both species.

Food Habits of Ring-necked Ducks Wintering in Florida Food habits of wintering ring-necked ducks (Aythya collaris) were determined by examining gullets from 597 birds collected in 3 regions of Florida. Fifty-five of the gullets contained trace amounts of food and 148 contained >1 ml. Forty-one foods were identified. Animal matter, principally snails, chironomids, and dragonflies, occurred in 43.6% of the samples containing food. Plant foods, principally hydrilla {Hydrilla verticillata), waterlilies (Nuphar advena, Nymphaea odorata, Brasenia scherberi), and sawgrass (Cladium jamaicense), occurred in 89.1 % of the samples containing food.

Reproductive Effort and Success in a Declining Wild Turkey Population We monitored reproductive effort and success of a wild turkey (Meleagris gallopavo) population on a public wildlife management area in Mississippi for 9 years using telemetry and other indices. Adult hens (N = 143) had a nesting rate of 72.7% (range 54-100) and was greater (P = 0.0001) than the nesting rate (26.7%) of juvenile hens (N = 15). Annual nest success of 104 nests of adult hens averaged 30.8% (range 0-62) and poult survival to >50 days was 22.7% for 27 broods (N = 203 poults). William E. Palmer, S. R. Priest, R. S. Seiss, P. S.

Habitat Use and Demography of a Wild Turkey Population Subjected to Human-induced Flooding From 1986 to 1988, we studied the demography and habitat use of an eastern wild turkey (Meleagris gallopavo silvestris) population subjected to humaninduced flooding along the Roanoke River, North Carolina. A six-month flood from 22 December 1986 to 22 June 1987 resulted in significant shifts in habitat use. Female home ranges during flooding were significantly larger than those recorded during non-flood periods. During non-flood periods, females used bottomland hardwoods more than other available habitats. David T. Cobb, P. D. Doerr, M. H. Seamster

Wild Turkey Food Habits in Pine Plantations in South Carolina A total of 1,576 wild turkey (Meleagris gallopavo) droppings (650 male and 926 female) was collected from 1 January-31 December 1989 on Westvaco's Oswald Unit located in Jasper County, South Carolina. This Unit is made up of loblolly pine plantations (77%), natural pine stands (10%), hardwood stands (5%), and open, nonforested areas (8%). Fecal analysis was used to determine food habitats. Forty-six food stuffs were identified, and there were no significant differences (P > 0.05) in food items by sex. William M. Baughman, D. C. Guynn, Jr.

Wildlife managers on public hunting areas are accountable for hunter success rates, annual harvest, and wildlife population size. Understanding the effect of changes in numbers of wild turkey gobblers (Meleagris gallopavo) on harvest characteristics is needed. Population size and harvest characteristics were studied for 9 years on a 14,140-ha public hunting area in central Mississippi. Male wild turkey population size averaged 82, hunter effort averaged 455 hunter-days per season, and an average of 35 male turkeys was harvested per season. John R. Lint, G. A. Hurst, K. D.

Mortality Patterns of Female White-tailed Deer in Southwest Florida Eleven of 66 radio-collared white-tailed deer (Odocoileus virginianus) in southwest Florida were killed by bobcats (Felis rufus) and 4 by Florida panthers {Felis concolor coryi). Average doe home range size was 194 ha, and 2 bucks ranged from 454-1,560 ha. There were no differences (P = 0.336) in doe survival rates among seasons. The average annual survival rate for does was 0.813 (95% CI- 0.68, 0.94) and 64% of the annual mortality was attributable to predation. Average neonate mortality rate was 37.8% ±16.1 and appeared to increase with surface water levels. E. Darrell Land, D. S. Mehr, J. C. Roof, J. W. McCown

Warm Season Supplemental Forages for White-tailed Deer in the Pineywoods of East Texas Supplemental forage plantings for white-tailed deer (Odocoileus virginianus) have been aimed primarily at the winter stress period with little or no consideration to supplementing the summer diet. Consequently, there is little information concerning the efficacy of summer plantings. A total of 14 summer cultivated forages was evaluated using 4 criteria: 1) productivity, 2) availability during stress periods, 3) utilization and acceptance by deer, and 4) nutritional quality.

Clinical Blood Profiles of Stressed White-tailed Deer: Drop-net versus Harvest We collected whole blood and serum samples from 50 harvested (unstressed) and 37 live-caught (handling stress in drop-net) adult white-tailed (Odocoileus virginianus) does to evaluate the influence of capture method on clinical blood parameters commonly used to assess nutritional condition of deer. Our study found mean values for HCT, MCV, WBC, lymphocytes, neutrophils, creatinine, cholesterol, total protein, albumin, globulin, Na, LDH, and GGTP to be significantly higher in live-caught than harvested does.

Electrophoretic Comparison of Road-killed Deer and Live-captured Deer Sampled by Muscle Biopsy A safe and effective muscle biopsy procedure that can be used to sample genetic variation in live white-tailed deer (Odocoileus virginianus) is described. The validity of this procedure for estimating genetic variability was confirmed by sampling blood and muscle from 78 road-killed and 57 captured deer at Chickamauga Battlefield National Military Park, Georgia, between June 1991 and June 1992. Six polymorphic loci were detected in muscle tissue and 2 polymorphic loci were found in blood using starch-gel electrophoresis. Mary J. Ratnaswamy, C. L. Rogers, R. J. Warren, M. H. Smith, K. A. K.

Survival Rates and Adult Accompaniment of White-tailed Deer Fawns on Remington Farms During the summer and fall of 1991 and 1992, 48 (21 M:27 F) white-tailed deer (Odocoileus virginianus) fawns were captured and radiocollared (N = 43) on Remington Farms near Chestertown, Maryland. Survival of radio-collared fawns, from 1 week old until the fall hunting season, was 91%. Collared fawn mortality (N = 9) was due to abandonment, tick infestation, infection, and roadkill. Visual locations (N = 1,229) were collected to determine adult accompaniment rates for radio-collared fawns. Brian M. Wickham, R. A. Lancia, M. C. Conner

Renovation of Johnsongrass Communities with Vetch to Benefit Northern Bobwhites Land taken out of cultivation in the Blackland Prairie soils of Alabama and Mississippi frequently reverts to a plant community dominated by Johnsongrass (Sorghum halepense), with co-dominants of marsh elder (Iva annua), verbena (Verbena brasiliensis), and Illinois bundleflower (Desmanthus illinoensis). These plant species are of little value as a food source for the northern bobwhite (Colinus virginianus) and eliminate many desirable quail food plants. Renovation of a Johnsongrass community was attempted by mowing during the fall and overseeding with hairy vetch (Vicia villosa). C. H. Bucciantini, Dale H. Arner, J.C. Jones

Effects of Six Disking Regimens on Quail Foods in Fallowed Fields The effect of disking fallowed agricultural fields was studied in the Piedmont and Coastal Plain of South Carolina. Six combinations of disking frequency and time-of-year and a control were tested. Although plant communities responded by returning to an earlier serai stage, well-established perennials prevented a complete return to Stage 1 succession. The effect of disking frequency proved more influential than that of time-of-year. Treatments were evaluated for their ability to produce food plants for northern bobwhite (Colinus virginianus).

Swamp Rabbit Distribution in Missouri We determined the distribution of swamp rabbits (Sylvilagus aquaticus) and bottomland hardwood forests, potential swamp rabbit habitat, in Missouri during the 1991-92 winter. Presence of swamp rabbits was determined from information gathered from resource managers and by searching habitat for fecal pellets. Most potential swamp rabbit habitat in Missouri is located in the southeast, and we documented 45,218 ha of bottomland hardwood forest there by measuring tracts identified on aerial photos. Thomas V.

Evaluating Micro-habitat Selection by Northern Bobwhite in Virginia We monitored radio-tagged northern bobwhites (Colinus virginianus) from January through July of 1990 and 1991 to determine if preferential habitat use occurred within the covey home range. We generated estimates of percent bare ground, average height of herbaceous vegetation, percent canopy cover of herbaceous vegetation and honeysuckle (Lonicera spp.), proportion of the herbaceous canopy represented by grasses, herbaceous quail foods, and woody vegetation <2 m tall at used and unused sites within 12 covey home ranges.

Response of Ground-level Wildlife Food Plants to Canopy Defoliation by the Gypsy Moth We studied changes in ground-level vegetation (shrubs, herbs, vines, trees) in a deciduous forest before (1984) and after (1987) the initial stages of a gypsy moth (Lymantria dispar) invasion. Seventeen of 18 plant species known to be important wildlife food plants increased in percent cover from 1984 to 1987. Total percent ground cover and plant species richness also increased. At the same time, the number of snags and snag basal area increased but not significantly, implying that the gypsy moth can be used as a management tool to enhance understory vegetation without harvesting trees.

Characteristics of Black Bear Mortality on the Coastal Plain of North Carolina Black bear (Ursus americanus) mortality data were collected in eastern North Carolina from 1976 to 1992. These data included registered harvest totals from mandatory hunter-harvest records, field reports, and tooth samples from bears dying of all causes (N = 1,107 for harvest; N = 350 for vehicle-kill). Increasing trends in harvest corresponded to establishment of seasons in 11 counties beginning in 1986. Vehicle-kills increased until 1990 but declined during 1991-92. Gordon S. Warburton, R. C.

Mercury Concentrations in Alligator Meat in Georgia Tail meat samples from 22 American alligators (Alligator mississippiensis) collected from 10 collection areas in Georgia during 1990 were analyzed for mercury (Hg) concentrations (wet weight basis). Mercury was detected in all samples and ranged from 0.1 ppm to 1.4 ppm (x = 0.48 ppm). No differences in mercury concentration were found between sexes (P = 0.638) or among all collection areas (P = 0.178). Pooled samples from collection sites on the headwaters of the Suwannee River system had higher mercury concentrations (P < 0.005) than those from all other collection sites combined.

Blood Lead Concentrations and Ingested Shot in Ring-necked Ducks at Catahoula Lake, Louisiana We analyzed blood lead concentrations and prevalences of ingested lead and steel shot in 93 ring-necked ducks (Aythya collaris) at Catahoula Lake, Louisiana. Blood lead concentrations were higher for immatures than for adults, but did not differ between sexes or between randomly collected and hunter-shot birds. Blood lead concentrations were elevated (≥ 0.20 ppm) in 18 of 31 immatures (58%) and 13 of 61 adults (21%), and were toxic (≥ 0.50 ppm) in 11 immatures (35%) and 5 adults (8%). Alan D.

Activity and Habitat Utilization of Beaver Colonies in South Carolina Movements, primary use areas, activity periods, and habitat use were evaluated for beaver (Castor canadensis) from 2 adjacent colonies, a stream colony, and a lake colony in the Piedmont of South Carolina. Beaver were monitored from February 1983 through March 1984. Minimum total distance moved by individual beaver ranged from 0.26 to 6.83 km. Distance between extreme locations ranged from 0.08 to 1.86 km. Lake colony beaver movements exceeded those of stream colony beaver. Beaver were more active during fall and winter months. Areas frequented by beaver ranged from 10.95 ha to 14.67 ha. J. Rickie Davis, D. C. Guynn, Jr.

The Wading Bird Protection Initiative: A Conservation Strategy The Florida Game and Fresh Water Fish Commission's Nongame Wildlife Program developed a ranking system to identify and prioritize those taxa within the state most in need of research and conservation efforts in order to focus limited staff and financial resources where they are most needed and can be most effective. Wading birds were identified as a priority group of taxa in need of conservation attention. An innovative plan was developed for addressing the conservation needs of that group. Nancy J. Douglas, M.

History of Cooperative Management of North Carolina's Colony-nesting Waterbirds North Carolina's colony-nesting waterbirds probably existed for thousands of years along nearly 500 km of coastal estuaries and barrier islands. Suffering from the effects of over-harvest by plume hunters and extensive loss of habitat due to coastal development, these birds began to receive notice during the 1970s. Studies of coastal community succession began in 1970 and quickly determined that dredged material islands provide essential habitat for colony-nesting waterbirds. In 1976, coastwide censuses were initiated to survey the 20-22 species suspected to nest in the state.

Effectiveness of Bald Eagle Habitat Protection Guidelines in Florida Aerial overflights were used to assess impacts of the application of habitat management guidelines to 24 experimental and 38 control bald eagle (Haliaeetus leucocephalus) nesting territories. No significant differences in productivity were found between nests where management guidelines had been applied and control nests where no development had occurred. No changes in the minimums called for in the guidelines or their application are indicated at this time. Stephen A. Nesbitt, M. J. Folk, D. A. Wood

Attitudes of Georgians Toward Nongame Wildlife: A Survey In 1988 the Georgia Department of Natural Resources contracted the Survey Research Center of the University of Georgia to conduct a telephone survey of public attitudes toward nongame wildlife. Phone numbers of potential respondents were selected using random digit dialing, a method that allowed all telephone households (97% of all Georgia households) an equal chance of being selected. Respondents were asked a series of 17 questions of which 12 pertained to interest in and support of nongame wildlife and 5 related to demographics. A total of 541 individuals were surveyed. Todd M.

Conservation of Aquatic Critical Habitats in North Carolina North Carolina's State Endangered Species Act for Animals was established in 1987. Since that time, approximately 200 species have been listed as endangered, threatened, or species of special concern. The act, however, provides few ways to prevent take of these species or to conserve the listed species' habitats. Therefore, state regulatory agencies have been establishing procedures for conserving wetland and aquatic endangered and threatened species. John M. Alderman, R. C. Wilson, C. McGrath

Survival and Longevity of Adult Male Florida Grasshopper Sparrows Survival and longevity were estimated for the endangered Florida grasshopper sparrow (Ammodramus savannarum floridanus) from resightings of 48 colorbanded adult males during 1989-1992. Annual survival rate was 0.598 and mean life expectancy was 2.95 years (1.95 years for sparrows >1 year old). The high survival rate and longevity of the subspecies may facilitate the recovery of populations remaining in good breeding habitat. Annual recruitment of 5.4 young per pair is needed to maintain a stable population of grasshopper sparrows on the study area. Michael F. Delany, C. T. Moore, D. R. Progulske

Historical Loss of Whooping Crane Habitat on the Aransas National Wildlife Refuge In October 1989, researchers at the U.S. Army Engineer Waterways Experiment Station (WES) initiated a project to investigate the historical loss of critical whooping crane (Grus americana) habitat on the Aransas National Wildlife Refuge. Vegetation on the area was categorized into 11 habitat types and manually delineated on aerial photos of the area from 1930, 1957, 1986, and 1988. Habitat type maps for each year were digitized into a Geographic Information System (GIS) database that included soils, topography, and National Wetland Inventory data. Darrell E. Evans, M. R. Waring

Distribution and Conservation of the Santa Rosa Beach Mouse The Santa Rosa beach mouse (Peromyscus polionotus leucocephalus) occurs on a single barrier island in northwest Florida, but its distribution on the island is poorly known. In 1991-92 we searched for mouse tracks at 1-km intervals along the 78-ktn island and set traps at 23 locations. Beach mice occurred in beach and interior dune habitats across most (96%) of the undeveloped stretches (57 km) of the island. Beach mice were significantly less common in areas developed for residential or commercial use and tracks were found along just 7 of 21 km of developed land. Jeffery A. Gore, T. L. Schaefer

Productivity of Reintroduced Peregrine Falcons in Western North Carolina Observers monitored a reintroduced peregrine falcon population in western North Carolina from 1987 to 1992. Five of 9 occupied territories produced 19 fledgling peregrines during the study. Productivity for the period was 0.59 young fledged per territory-holding pair per year when using the full data set and 0.79 young fledged per territory-holding pair per year when we dropped marginal territories and 1 adult-subadult pair from the data set. Both estimates of productivity were below that thought necessary for a self-sustaining population.

Do Mountain Lions Exist in Arkansas? Surveys covering over 1,161,140 ha in Arkansas from 1988-1991 revealed abundant sign of several native and domesticated mammal species, but none from the mountain lion (Felis concolor). Because of our intensive methodology and the equivocal nature of previous documentation, we suggest there are no wild, reproducing populations of mountain lions in Arkansas. Extensive forests in the state, however, may provide suitable habitat for mountain lion reintroduction experiments. Roy T. McBride, R. M. McBride, J. L. Cashman, D. S. Maehr

Status of the Green Salamander in South Carolina In 1989 and 1990 a green salamander (Aneides aeneus) habitat study was conducted in the mountains of Oconee, Pickens, and Greenville counties, South Carolina. Based upon the topographic characteristics of 14 known green salamander sites in South Carolina, a list of criteria was developed to identify areas of potential habitat in the state. Twenty-four 7.5' topographic maps containing areas with possible habitat were subdivided into 0.16-km2 sections and evaluated to determine the number of potential green salamander habitat areas.

Gopher Tortoise Response to Large-scale Clearcutting in Northern Florida A previously studied (1981-1987) gopher tortoise (Gopherus polyphemus) population in northern Florida was surveyed during May-June 1992 to determine tortoise response to large-scale timber removal (1988). Two of 3 burrow concentrations were in or near ecotones between the clearcut and older pine stands. Eighteen of 23 (78%) recaptured tortoises were found in the same general location after clearcutting as before. One female had moved 1.3 km from her previous capture location. Only 13% of all previously-marked tortoises were recaptured in 1992. Joan E. Diemer Berish C. T. Moore

How Much Management Emphasis Should Neotropical Migrants Receive in the Southeast? Widespread concern for neotropical migratory birds should be tempered with a review of the status of all landbirds, regardless of migratory status. A relationship exists between the proportion of declining neotropical migrants and temperate migrants, but not residents, among Southeastern physiographic areas. However, within physiographic areas where proportions of declining neotropical migrants are high, proportions of declining temperate migrants and residents are not as high.

Neotropical Migratory Bird Communities in a Developing Pine Plantation Birds were censused annually from 4 250- x 80-m transects in a young pine plantation from age 2 to 17 to assess changes in the bird community. Bird abundance was low and the bird community was the least diverse when the pine plantation was sparsely vegetated at age 2. As the plantation developed rapidly into the shrub stage, the bird community became more abundant and diverse. Bird abundance increased consistently until plantation age 6, but then declined as the pine canopy closed and shaded out lower deciduous vegetation. James G. Dickson, R. M. Conner, J. H. Williamson
