The literature contains numerous studies on Red-winged Blackbird (Agelaius phoeniceus) reproduction. Francis (1971) summarized eight studies dealing with nesting success. These and other studies have also provided information on breeding chronology, clutch sizes, sex ratios, survival rates for eggs and nestlings, reproductive physiology, and other life history aspects of reproduction. With few exceptions, these studies have provided no data on the number of young fledged per female, per territorial male, or per unit area. This is especially true for upland nesting habitats where, at least in the midwestern United States, most Red-wings now nest (Graber and Graber 1963, Dyer et al. 1973). Also insufficient quantitative information is available on the extent and nature of renesting (i.e. nesting more than once in a nesting season) and on movements of adult females during the nesting season.
A better understanding of these aspects of reproduction is critical for the development of an accurate population-dynamics model for the species. Such a model is sorely needed to evaluate the impact and effectiveness of proposed population management strategies in places where blackbirds are deemed a health or safety hazard, or cause damage to agricultural crops (Tosh et al. 1970, Solman 1971, Stone et al. 1972).
This study had three objectives: (1) to determine the distribution, size, and number of Red-winged Blackbird territories for an old-field habitat; (2) to determine the number of nesting females, nesting success, extent of renesting, and number of young fledged for these territories; and (3) to examine movements of female Red-wings during the nesting season.

Ten vyolves (Canis lupus) from 7 packs in the same area were radiotracked before and/or during the same period (703 locations). Deer had winter ranges averaging 26.4 ha. Spring migration took place from 26 March to 23 April and was related to loss of snow cover. Deer generally migrated ENE in straight-line distances of 10.0 to 38.0 km to summer ranges. Two fawns did not migrate. Arrival on summer ranges was between 19 April and 18 May, and summer ranges varied from 48.1 to 410.4 ha. Migration back to the same winter yards took place in early December, coincident with snow accumulation and low temperatures. Social grouping appeared strongest during migration and winter yarding. Survival of the radio-tagged deer was studied through 1 May 1975. Four deer were killed by wolves, one was poached, and one drowned. Mean age of the captured deer was 5.4 years and estimated minimum survival after capture was 2.6 years, giving an estimated total minimum survival of 8.0 years. This unusually high survival rate appeared to be related to the fact that both winter and summer ranges of these deer were situated along wolf-pack territory edges rather than in centers. In addition, most summer ranges of the radio-tagged deer were along major waterways where the deer could escape wolves.

Livers, kidneys, blood, wingbones, and eggs were analyzed for lead by atomic absorption. Necropsy of sacrificed ducks failed to reveal any of the tissue lesions usually associated with lead poisoning in waterfowl. Lead levels in ducks given all-lead shot averaged about twice those in ducks given lead-iron shot, reflecting the amount of lead in the two types of shot. Lead in the blood of ducks dosed with all-lead shot averaged 0.64 ppm, and 0.28 ppm in ducks given lead-iron shot. Lead residues in livers and kidneys of females given all-lead shot were significantly higher than in males. In both dosed groups, lead levels in wingbones of females were about 10 times those in males, and were significantly correlated with the number of eggs laid after dosage. Lead levels in contents and shells of eggs laid by hens dosed with all-lead shot were about twice those in eggs laid by hens dosed with lead-iron shot. Eggshells were found to best reflect levels of lead in the blood. Our results indicate that mallards maintained on a balanced diet and dosed with one lead shot may not accumulate extremely high lead levels in the liver and kidney. However, extremely high lead deposition may result in the bone of laying hens after ingesting sublethal amounts of lead shot as a result of mobilization of calcium from the bone during eggshell formation.","language":"English","publisher":"Springer","doi":"10.1007/BF01685887","usgsCitation":"Finley, M.T., Dieter, M.P., and Locke, L.N., 1976, Lead in tissues of mallard ducks dosed with two types of lead shot: Bulletin of Environmental Contamination and Toxicology, v. 16, no. 3, p. 261-269, https://doi.org/10.1007/BF01685887.","productDescription":"9 p.","startPage":"261","endPage":"269","numberOfPages":"9","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":198404,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"16","issue":"3","noUsgsAuthors":false,"publicationDate":"2013-08-31","publicationStatus":"PW","scienceBaseUri":"4f4e4893e4b07f02db520a30","contributors":{"authors":[{"text":"Finley, M.

Observations by a Z-man team using walkie-talkies revealed that breeding robins obtained essentially all food for themselves and nestlings from unsprayed areas adjacent to the orchards. Invertebrate trapping in sprayed and unsprayed areas showed that these food items were 5 or 6 times more abundant in unsprayed habitat. Worms forced to live in sprayed orchard soil displayed significantly greater mortality than controls. Mean robin clutch sizes in the study orchards were lower than those reported for robins in other studies, perhaps because of food shortage and/or increased foraging distances. Levels of DDT and its analogs in food items from robin foraging areas did not exceed 8 ppm wet weight basis. From late April to July, adult robins showed small but significant increases in DDE levels in all tissues examined, as well as an increase in dieldrin in brains. Pesticides sprayed on the farm had no direct demonstrable adverse effects on the robins; productivity was high and adult mortality low. The situation was in large measure fortuitous, since any changes in orchard management practices which resulted in the presence or availability of invertebrates under orchard trees would be expected to result in robin mortality and/or reduced breeding success.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wilson Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Johnson, E., Mack, G., and Thompson, D., 1976, The effects of orchard pesticide applications on breeding robins: The Wilson Bulletin, v. 88, no. 1, p. 16-35.","productDescription":"16-35","startPage":"16","endPage":"35","numberOfPages":"20","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":18121,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://elibrary.unm.edu/sora/Wilson/v088n01/p0016-p0035.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":199186,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"88","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699d39","contributors":{"authors":[{"text":"Johnson, E.V.","contributorId":39080,"corporation":false,"usgs":true,"family":"Johnson","given":"E.V.","email":"","affiliations":[],"preferred":false,"id":333661,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mack, G.L.","contributorId":36654,"corporation":false,"usgs":true,"family":"Mack","given":"G.L.","email":"","affiliations":[],"preferred":false,"id":333660,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Thompson, D.Q.","contributorId":50991,"corporation":false,"usgs":true,"family":"Thompson","given":"D.Q.","email":"","affiliations":[],"preferred":false,"id":333662,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":5221374,"text":"5221374 - 1976 - Methylmercury: Second generation reproductive and behavioral effects of mallard ducks","interactions":[],"lastModifiedDate":"2020-05-13T21:01:41.484524","indexId":"5221374","displayToPublicDate":"2010-06-16T12:19:14","publicationYear":"1976","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2508,"text":"Journal of Wildlife Management","active":true,"publicationSubtype":{"id":10}},"title":"Methylmercury: Second generation reproductive and behavioral effects of mallard ducks","docAbstract":"Mallard ducks (Anas platyrhynchos) whose parents were fed a diet containing 0.5 ppm mercury (equal to about 0.1 ppm mercury in a natural diet) also were fed a diet containing 0.5 ppm mercury beginning at 9 days of age and continuing through their reproductive season.

There were no significant differences in egg production or hatching success among controls and groups fed mercury. Ducklings from hens fed 3 ppm mercury were less likely to survive to 1 week of age than were controls or ducklings from parents fed 0.5 ppm mercury. There were no significant differences in approach behavior among the offspring of controls and groups fed mercury. In avoidance behavior, ducklings whose parents were fed 3 ppm mercury were hyper-responsive compared with controls and ducklings from parents fed 0.5 ppm mercury.

The collection included 43 big brown bats (Eptesicus fuscus), 43 little brown brown bats (Myotis lucifugus), and 33 eastern pipistrelles (Pipistrellus subflavus). The bats were collected from Round Top Mountain, Washington Co., Md.; Trout Cave, Pendleton Co., W. Va.; Montpelier Barn, Prince Georges Co., Md. Residues of sigmaDDT were highest in carcasses of bats from Round Top Mountain, which is surrounded by apple orchards. Bats from Trout Cave had the lowest residues, a circumstance which probably reflects the absence of agriculture and industry in the area. A polychlorinated biphenyl (PCB) and oxychlordane were highest at Montpelier Barn. Sources of the PCB are unknown, but chlordane is used against termites and in gardening at nearby housing developments. Residues in bats from North East Methodist Church were low except for dieldrin. Among species, little brown bats usually had the highest residue concentrations in their carcasses, whereas big brown bats had the lowest. When DDE in carcass fat of all species was above 60-90 ppm, it became measurable in brain tissue. Above 60-90 ppm, DDE levels in brains rose with increasing levels in carcass lipids. Residues of the PCB tended to respond similarly. Residue levels in brains were greatest in little brown bats; the maximum level of the PCB, 7.9 Ppm, was more than twice that of DDE.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pesticides Monitoring Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Clark, D.R., and Prouty, R.M., 1976, Organochlorine residues in three bat species from four localities in Maryland and West Virginia, 1973: Pesticides Monitoring Journal, v. 10, no. 2, p. 44-53.","productDescription":"44-53","startPage":"44","endPage":"53","numberOfPages":"10","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":197004,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269758,"type":{"id":11,"text":"Document"},"url":"https://biodiversitylibrary.org/page/26096130"}],"volume":"10","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae5e4b07f02db68a72b","contributors":{"authors":[{"text":"Clark, D.

Eleven bats were adult females, and six of these had seven nursing young associated with them....Young bats resembled their parents in microgram amounts of PCB and DDE present in carcasses. However, concentrations of chemicals (expressed as ppm) were significantly higher in young. Brains of three young contained detectable residues of PCB and DDE....Younger adult females contained higher levels of PCB and DDE than did older ones. However, among the oldest females, amounts appeared to begin rising again. This pattern resembles that in free-tailed bats from Bracken Cave, Texas, but differs from the continuous linear decline seen in a Laurel, Maryland population of big brown bats, in which initial levels among younger females were higher than those in the Gaithersburg population....DDE was transferred from female to young more readily than was PCB by nursing. Five of 51 neonate big brown bats from the Laurel population were thought to have been born dead because of residues of PCB that were transferred across the placenta. Present data show that even greater amounts of PCB may be transferred to young by lactation and nursing.","language":"English","publisher":"Springer","doi":"10.1007/BF01686188","usgsCitation":"Clark, D.R., and Lamont, T.G., 1976, Organochlorine residues in females and nursing young of the big brown bat (Eptesicus fuscus): Bulletin of Environmental Contamination and Toxicology, v. 15, no. 1, p. 1-8, https://doi.org/10.1007/BF01686188.","productDescription":"8 p.","startPage":"1","endPage":"8","numberOfPages":"8","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":198457,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae5e4b07f02db68a65e","contributors":{"authors":[{"text":"Clark, D.

The probability of observing a point given its right angle distance (y) from the line is generalized to an arbitrary function g(y). Given only that g(0) = 1, it is shown there are nonparametric approaches to density estimation using the observed right angle distances. The model is then generalized to include sighting distances (r). Let f(y I r) be the conditional distribution of right angle distance given sighting distance. It is shown that nonparametric estimation based only on sighting distances requires we know the transformation of r given by f(0 I r).","language":"English","publisher":"International Biometric Society","doi":"10.2307/2529501","usgsCitation":"Burnham, K., and Anderson, D., 1976, Mathematical models for non-parametric inferences from line transect data: Biometrics, v. 32, no. 2, p. 325-336, https://doi.org/10.2307/2529501.","productDescription":"12 p.","startPage":"325","endPage":"336","numberOfPages":"12","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":194063,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"32","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a27e4b07f02db60fff7","contributors":{"authors":[{"text":"Burnham, K.P.","contributorId":63760,"corporation":false,"usgs":true,"family":"Burnham","given":"K.P.","email":"","affiliations":[],"preferred":false,"id":332837,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Anderson, David R.","contributorId":8413,"corporation":false,"usgs":true,"family":"Anderson","given":"David R.","affiliations":[],"preferred":false,"id":332836,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":5223477,"text":"5223477 - 1976 - Reflective plate glass--a hazard to migrating birds","interactions":[],"lastModifiedDate":"2023-11-05T15:00:38.180955","indexId":"5223477","displayToPublicDate":"2010-06-16T12:19:11","publicationYear":"1976","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":997,"text":"BioScience","active":true,"publicationSubtype":{"id":10}},"title":"Reflective plate glass--a hazard to migrating birds","docAbstract":"No abstract available.

Fish, mostly alewives (Alosa pseudoharengus), comprised the major year-round food items in the wild; alewives were also fed to the caged juveniles. Fish residues averaged around 3 mg/kg of p,p'-DDE, 2 mg/kg p,p'DDT + p,p'-TDE, and 2 mg/kg apparent PCBs. Juvenile body-burdens of DDE and PCBs showed a continual buildup after fledging, then a temporary dynamic equilibrium, related only in part to annual lipid deposition. Maximum body-burdens were reached in both juveniles and adults when winter fat deposits were declining prior to the breeding season?followed by a return to dynamic equilibrium. Residues of DDT and TDE followed closely the annual pattern of lipid deposition in both juveniles and adults. Total body-burdens in both age classes were similar after the buildups to equilibrium in juveniles in their eighth month after fledging. Seasonal variations of residues of DDE and PCBs were characterised by two phases in adults and three in juveniles, which gradually assumed the adult cyclic pattern. The maximum body-burdens attained by caged juveniles fed a diet of Lake Michigan alewives were 290 mg/kg DDE, 19 mg/kg DDT + TDE, and 200 mg/kg apparent PCBs. Residues in wild adults at the same time were 300, 4, and 200 mg/kg of the same residues. Apparent PCBs and DDE were highly accumulative, although DDE levels resulted from dietary DDE, as well as conversion from DDT.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Pollution","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/0013-9327(76)90036-7","usgsCitation":"Anderson, D.W., and Hickey, J., 1976, Dynamics of storage of organochlorine pollutants in herring gulls: Environmental Pollution, v. 10, no. 3, p. 183-200, https://doi.org/10.1016/0013-9327(76)90036-7.","productDescription":"183-200","startPage":"183","endPage":"200","numberOfPages":"18","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":196161,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":18057,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://dx.doi.org/10.1016/0013-9327(76)90036-7","linkFileType":{"id":5,"text":"html"}}],"volume":"10","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a59e4b07f02db62f847","contributors":{"authors":[{"text":"Anderson, D.
