| studies of endoparasites of the mourning dove (zenaida macroura) in the southeast united states. | from september, 1973, through november, 1974, 255 mourning doves (zenaida macroura) were collected in the southeastern united states and examined for endoparasites. thirteen species of endoparasites were found and included six species of protozoans, one trematode, two cestodes, and four nematodes. new host records included sarcocystis sp., echinostoma revolutum, hymenolepis sp., aproctella stoddardi, ascaridia columbae, and dispharynx nasuta. | 1977 | 402483 |
| comparison of direct and modified direct complement-fixation and agar-gel precipitin methods in detecting chlamydial antibody in wild birds. | detection of chlamydial antibody in serums of wild birds was compared for the following methods: direct complement-fixation (dcf), modified dcf (mdcf), and agar-gel precipitin (agp). the birds species used were great-tailed grackles (cassidix mexicanus), common grackles (quiscalus quiscula), brown-headed cowbirds (molothrus ater), bronzed cowbirds (tangavius aeneus), and mourning doves (zenaida macroura). the birds were either inoculated with an isolate of chlamydia psittaci obtained originally ... | 1978 | 100098 |
| the culex pipiens complex in the mississippi river basin: identification, distribution, and bloodmeal hosts. | members of the culex pipiens complex are the primary vectors of st. louis encephalitis virus and west nile virus in the mississippi river basin (mrb). the cx. pipiens complex in the mrb is composed of 4 taxa: cx. p. pipiens form pipiens, cx. p. quinquefasciatus, hybrids between cx. p. pipiens f. pipiens and cx. p. quinquefasciatus, and cx. p. pipiens form molestus. three studies on bloodmeal hosts with large sample sizes have been conducted on members of the cx. pipiens complex in the mrb includ ... | 2012 | 23401948 |
| vector-host interactions of culex pipiens complex in northeastern and southwestern usa. | studies on the vector-host interactions of culex pipiens complex mosquitoes by sequencing portions of mitochondrial cytochrome b gene indicate that cx. p. pipiens f. pipiens predominantly feed on avian hosts (93.1%), and focus feeding activity on several key bird species, in particular the american robin, the gray catbird, and the house sparrow in connecticut. however, cx. p. quinquefasciatus indiscriminately feed on both birds and mammals. culex p. quinquefasciatus in harris county - texas and ... | 2012 | 23401953 |
| condition-specific competition governs the geographic distribution and diversity of ectoparasites. | understanding how environmental parameters interact to govern species distributions is a shared goal of ecology and biogeography. biotic and abiotic conditions can change distributions by affecting the nature of interspecific interactions. although documented in free-living systems, this context dependency has been neglected in parasite interactions. we investigated the influence of condition-specific competition on the specificity of two species of feather lice (phthiraptera: ischnocera) that s ... | 2011 | 21460573 |
| retinal ganglion cell topography of five species of ground-foraging birds. | birds that forage on the ground have been studied extensively in relation to behavioral trade-offs between foraging and scanning for predators; however, we know little about the topography of their retinas, which can influence how they gather visual information. we characterized the density of retinal ganglion cells across the retina and estimated visual acuity of four passeriformes (european starling sturnus vulgaris, brown-headed cowbird molothrus ater, house sparrow passer domesticus, house f ... | 2010 | 20516656 |
| pathophysiological responses to a schistosome infection in a wild population of mourning doves (zenaida macroura). | the blood trematode gigantobilharzia huronensis typically infects passerine birds and has not been reported in other orders of wild birds. however, in the summer of 2011 in tempe, arizona, usa, mourning doves (zenaida macroura; order: columbiformes) were collected with infections of g. huronensis. this is the first report of a natural schistosome infection found in wild populations of doves. we sought to determine if g. huronensis infections alter the general body condition and physiology of dov ... | 2015 | 26265584 |
| identification of bloodmeals in anopheles quadrimaculatus and anopheles punctipennis from eastern equine encephalitis virus foci in northeastern u.s.a. | the host-feeding patterns of anopheles quadrimaculatus say and anopheles punctipennis (say) were examined in order to evaluate their potential contributions to the transmission of eastern equine encephalitis virus (eeev) and other arboviruses in the northeastern u.s.a. engorged mosquitoes of the two species were collected from eeev foci in central new york (ny) and throughout new jersey (nj), and their bloodmeals were identified using a polymerase chain reaction (pcr)-based assay and sequencing ... | 2009 | 19941600 |
| association between agricultural land use and west nile virus antibody prevalence in iowa birds. | in the plains states of the central united states, research suggests that the prevalence of west nile virus (wnv) disease in humans is higher in agricultural areas than in nonagricultural areas. in contrast, there is limited information about wnv exposure in birds, the primary amplifying host of wnv, in agriculturally dominated landscapes. we evaluated whether exposure to wnv in peridomestic birds sampled in central iowa varied with the proportion of land use devoted to agriculture. over the sum ... | 2013 | 24502714 |
| management of fat reserves in tufted titmice baelophus bicolor in relation to risk of predation. | fat reserves are an important energy source for animals wintering in temperate zones. long nights, low ambient temperature and often unpredictable food all increase the probability of death from starvation, and to survive, animals carry energy reserves as fat. based on the assumption that extra weight makes birds more vulnerable to diurnal predators, it has been hypothesized that predation risk places an upper limit on avian fat reserves. the hypothesis leads to the prediction that birds should ... | 1998 | 9710461 |
| 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 |
| probabilistic model for estimating field mortality of target and non-target bird populations when simultaneously exposed to avicide bait. | a probabilistic model was developed to estimate target and non-target avian mortality associated with the application of the avicide cpth (3-chloro-p-toluidine hydrochloride) to minimize sprouting rice damage in the southern usa. cpth exposures for individual birds were predicted by random sampling from species-specific non-parametric distributions of bait seed consumption and cpth residues detected on individual bait seeds. mortality was predicted from the species-specific exposure versus morta ... | 2005 | 15747324 |
| blood plasma chemistries from wild mourning doves held in captivity. | despite the extensive amount of research conducted on mourning doves (zenaida macroura), no biochemical reference values exist for this species. our objective, therefore, was to establish base line clinical chemistry reference values for mourning doves to assist with establishing clinical diagnoses. wild mourning doves were captured 19 march 1996 to 8 august 1996, and 6 february 1998 to 12 may 1998; blood samples were collected from 382 mourning doves. plasma biochemical values were established ... | 2000 | 10941741 |
| mourning dove (zenaida macroura) wing-whistles may contain threat-related information for con- and hetero-specifics. | distinct acoustic whistles are associated with the wing-beats of many doves, and are especially noticeable when doves ascend from the ground when startled. i thus hypothesized that these sounds may be used by flock-mates as cues of potential danger. to test this hypothesis, i compared the responses of mourning doves (zenaida macroura), northern cardinals (cardinalis cardinalis), and house sparrows (passer domesticus) to audio playbacks of dove 'startle wing-whistles', cardinal alarm calls, dove ... | 2008 | 18551267 |
| concentration of contaminants in breeding bird eggs from the colorado river delta, mexico. | organic contaminants (organochlorine [oc], organophosphorus [op] pesticides and polychlorinated biphenyls [pcbs]), and metals (as, cd, hg, pb, and se) are a concern to avian health in the colorado river delta, mexico. we determined concentrations of contaminants in eggs of three breeding species of birds from the delta (mourning doves [zenaida macroura], burrowing owls [athene cunicularia], and marsh wrens [cistothorus palustris]). we collected 27 eggs of mourning doves, eight eggs of burrowing ... | 2006 | 16764484 |
| avian thermoregulation in the heat: resting metabolism, evaporative cooling and heat tolerance in sonoran desert doves and quail. | birds in subtropical deserts face significant thermoregulatory challenges because environmental temperatures regularly exceed avian body temperature. to understand the differing susceptibility of desert birds to increasing temperatures, we examined thermoregulatory performance and estimated heat tolerance limits (htls) for three sonoran desert nesting bird species - gambel's quail, mourning doves and white-winged doves. using flow-through respirometry we measured daytime resting metabolism, evap ... | 2015 | 26582934 |
