| observations on the involvement of wildlife in an epornitic of chlamydiosis in domestic turkeys. | in an investigation of potential wildlife reservoirs of chlamydia psittaci at the site of an acute, highly fatal epornitic of chlamydiosis in domestic turkeys in texas, various species of wild birds and rodents were captured and tested for chlamydial serum antibodies and chlamydiae in their tissues. thirteen (65%) of 20 blackbirds (agelaius sp), 4 (44%) of 9 killdeer (oxyechus vociferus), 3 (27%) of 11 sparrows (passer sp) and 1 of 4 mourning doves (zenaidura macroura) were seropositive, but chl ... | 1976 | 988009 |
| black-tailed prairie dogs and the structure of avian communities on the shortgrass plains. | we tested the hypothesis that black-tailed prairie dogs (cynomys ludovicianus) influence avian community structure on the shortgrass prairie. we surveyed 36 prairie dog towns and 36 paired sites without prairie dogs during summer and fall of 1997, 1998, and 1999 in the oklahoma panhandle. our surveys totaled 9,040 individual observations for 73 avian species. significantly distinct avian communities were present on prairie dog towns when compared to sites within four different macrohabitats of t ... | 2004 | 14685848 |
| helminth parasites in six species of shorebirds (charadrii) from the coast of belize. | thirteen species of helminth parasites were recovered from six species of charadriid shorebirds (aves: charadriiformes) from belize: the ruddy turnstone, arenaria interpres, the snowy plover, charadrius alexandrinus, the semipalmated plover, c. semipalmatus, the killdeer, c. vociferus, the white-rumped sandpiper, calidris fuscicollis, and the black-bellied plover, pluvialis squatarola. cestode species were predominant (n = 8), followed by trematode species (n = 3) and acanthocephala (n = 2). the ... | 2001 | 11562710 |
| a review of the mite subfamily harpirhynchinae (acariformes: harpirhynchidae)--parasites of new world birds (aves: neognathae). | mites of the subfamily harpirhynchinae (acariformes: cheyletoidea: harpirhynchidae) associated with neognathous birds (aves: neognathae) in the new world are revised. in all, 68 species in 8 genera are recorded. among them, 27 new species and 1 new genus are described as new for science: harpyrhynchoides gallowayi bochkov, oconnor and klompen sp. nov. from columba livia (columbiformes: columbidae) from canada (manitoba), h. zenaida bochkov, oconnor and klompen sp. nov. from zenaida macroura (col ... | 2015 | 26624161 |
| avian vacuolar myelinopathy outbreaks at a southeastern reservoir. | avian vacuolar myelinopathy (avm) is a neurologic disease of unknown etiology that affects bald eagles (haliaeetus leucocephalus), american coots (fulica americana), and several species of waterfowl. an unidentified neurotoxin is suspected as the cause of avm, which has been documented at several reservoirs in the southeastern united states. we conducted diagnostic and epidemiologic studies annually during october-march from 1998-2004 at clarks hill/strom thurmond lake on the georgia/south carol ... | 2006 | 17092880 |
| variable effects of climate change on six species of north american birds. | many recent studies have shown that birds are advancing their laying date in response to long-term increases in spring temperatures. these studies have been conducted primarily in europe and at local scales. if climate change is a large-scale phenomenon, then we should see responses at larger scales and in other regions. we examined the effects of long-term temperature change on the laying dates and clutch sizes of six ecologically diverse species of north american birds using 50 years of nest r ... | 2005 | 16096849 |
| associations of grassland bird communities with black-tailed prairie dogs in the north american great plains. | colonial burrowing herbivores can modify vegetation structure, create belowground refugia, and generate landscape heterogeneity, thereby affecting the distribution and abundance of associated species. black-tailed prairie dogs (cynomys ludovicianus) are such a species, and they may strongly affect the abundance and composition of grassland bird communities. we examined how prairie dog colonies in the north american great plains affect bird species and community composition. areas occupied by pra ... | 2013 | 23330695 |
| use of aquaculture ponds and other habitats by autumn migrating shorebirds along the lower mississippi river. | populations of many shorebird species are declining; habitat loss and degradation are among the leading causes for these declines. shorebirds use a variety of habitats along interior migratory routes including managed moist soil units, natural wetlands, sandbars, and agricultural lands such as harvested rice fields. less well known is shorebird use of freshwater aquaculture facilities, such as commercial cat- and crayfish ponds. we compared shorebird habitat use at drained aquaculture ponds, moi ... | 2013 | 23733250 |

| incidental kill of dunlin and killdeer by strychnine. | strychnine poisoning of 36 dunlin (calidris alpina) and two killdeer (charadrius vociferus) in yolo county, california (usa) was documented from 11 to 17 december 1990. birds were found dead on a field containing treated wheat seeds (337 micrograms strychnine/g seed) in postures consistent with the known physiopathology of strychnine poisoning: rapid rigor mortis, wings folded over backs, straightened toes, and fecal material extruding from vents. five dunlin and two killdeer were necropsied, an ... | 1995 | 8592394 |
| composition and diversity of avian communities using a new urban habitat: green roofs. | green roofs on buildings are becoming popular and represent a new component of the urban landscape. public benefits of green roof projects include reduced stormwater runoff, improved air quality, reduced urban heat island effects, and aesthetic values. as part of a city-wide plan, several green roofs have been constructed at chicago's o'hare international airport (ord). like some other landscaping features, green roofs on or near an airport might attract wildlife and thus increase the risk of bi ... | 2016 | 26956765 |
| foraging ecology of fall-migrating shorebirds in the illinois river valley. | populations of many shorebird species appear to be declining in north america, and food resources at stopover habitats may limit migratory bird populations. we investigated body condition of, and foraging habitat and diet selection by 4 species of shorebirds in the central illinois river valley during fall migrations 2007 and 2008 (killdeer [charadrius vociferus], least sandpiper [calidris minutilla], pectoral sandpiper [calidris melanotos], and lesser yellowlegs [tringa flavipes]). all species ... | 2012 | 23028795 |
| restoring fire to grasslands is critical for migrating shorebird populations. | fire is a disturbance process that maintains the structure and function of grassland ecosystems while sustaining grassland biodiversity. conversion of grasslands to other land uses coupled with altered disturbance regimes has greatly diminished the habitat available to many grassland-dependent species. these changes have been linked to declines in breeding bird populations, but may also be critical for migrating bird populations such as those shorebird species that depend on mesic grasslands dur ... | 2017 | 28464361 |
| incubation temperature and pcb-126 exposure interactively impair shorebird embryo and post-hatch development. | in oviparous wildlife, many critical physiological and behavioural components are strongly influenced by the embryonic and early post-hatch developmental environment. as such, early life stages in these species are highly vulnerable to both natural and anthropogenic stressors. for example, in birds, incubation temperature may influence the rate of egg development while also affecting contaminant metabolism and absorption in body tissues, resulting in potentially multiplicative impacts on embryon ... | 2020 | 32590146 |
| minerals in the human body: erionite and offretite from the killdeer mountains, dunn county, north dakota, u.s.a. | the carcinogenic potential of erionite has sparked concern about human exposure in areas where it is present in regional bedrock. the arikaree formation in western north dakota contains altered tuffaceous units with authigenic zeolites. we sampled stratigraphic profiles in the killdeer mountains, dunn county, north dakota, to determine the distribution and chemical composition of zeolites. powder x-ray diffraction, sem/eds and electron microprobe analyses were carried out on sample concentrates. ... | 2014 | 30542213 |
| reference genomes from distantly related species can be used for discovery of single nucleotide polymorphisms to inform conservation management. | threatened species recovery programmes benefit from incorporating genomic data into conservation management strategies to enhance species recovery. however, a lack of readily available genomic resources, including conspecific reference genomes, often limits the inclusion of genomic data. here, we investigate the utility of closely related high-quality reference genomes for single nucleotide polymorphism (snp) discovery using the critically endangered kakī/black stilt (himantopusnovaezelandiae) a ... | 2018 | 30583569 |
| embryonic brain growth in two shorebirds: charadrius vociferus and gallinago gallinago. | the sizes of six brain regions and of the whole brain were measured for a series of embryonic killdeer, charadrius vociferus, and common snipe, gallinago gallinago, to examine (1) the allometric relationship between whole brain and body mass through ontogeny, (2) whether the longer incubation period of the killdeer corresponds to a larger brain at hatch, (3) whether different brain regions grow independently in size through ontogeny, and (4) whether relative size of particular brain regions rela ... | 1996 | 8828861 |
| chemical defense in the plant bug lopidea robiniae (uhler). | secretions from the metathoracic glands (mtg) of the black locust bug, lopidea robiniae (uhler) (heteroptera: miridae) contained six major compounds, including (e)-2-hexenal, (e)-2-hexen-1-ol, (e)-2-octenal, (e)-2-octen-1-ol (e)-2-heptenal, and (z)-3-octen-1-ol. males and females did not differ significantly in the relative compositions of identified compounds. in feeding trials, six bird species [robin (turdus migratorious), blue jay (cyanocitta cristata), brown thrasher (toxostoma rufum), kill ... | 2002 | 11944836 |
| long-distance dispersal of seeds by retention in digestive tract of birds. | viable seeds of celtis, convolvulus, malva, and rhus were regurgitated from the digestive tract of kill-deer (charadrius vociferus) after 160, 144, 152, and 340 hours, respectively; seeds were recovered in the same way, after long-time retention, from least sandpipers (erolia minutilla). most other birds do not retain seeds as long. there is evidence that seeds of many species can remain viable in the intestinal tract of some shorebirds long enough to be transported several thousand miles. | 2014 | 4230509 |
