| trypanosomes of some sub-saharan birds. | linear measurements and derived indices from striated trypanosomes in nine species of sub-saharan birds representing seven families of the passeriformes, were compared. the dimensions of the striated trypomastigotes from the carduelinae, estrildidae, nectarinidae, passeridae, pycnonotidae, turdinae and zosteropidae were similar to each other as well as to those of the striated trypanosomes from the boreal owl (strigidae). all these trypanosomes were considered to be trypanosoma avium danilewsky, ... | 1994 | 7596580 |
| Comparative analysis of mineralocorticoid receptor expression among vocal learners (Bengalese finch and budgerigar) and non-vocal learners (quail and ring dove) has implications for the evolution of avian vocal learning. | Mineralocorticoid receptor is the receptor for corticosteroids such as corticosterone or aldosterone. Previously, we found that mineralocorticoid receptor was highly expressed in song nuclei of a songbird, Bengalese finch (Lonchura striata var. domestica). Here, to examine the relationship between mineralocorticoid receptor expression and avian vocal learning, we analyzed mineralocorticoid receptor expression in the developing brain of another vocal learner, budgerigar (Melopsittacus undulatus) ... | 2011 | 22010640 |

| avian thermoregulation in the heat: efficient evaporative cooling allows for extreme heat tolerance in four southern hemisphere columbids. | birds show phylogenetic variation in the relative importance of respiratory versus cutaneous evaporation, but the consequences for heat tolerance and evaporative cooling capacity remain unclear. we measured evaporative water loss (ewl), resting metabolic rate (rmr) and body temperature (tb) in four arid-zone columbids from southern africa [namaqua dove (oena capensis, ∼37 g), laughing dove (spilopelia senegalensis, ∼89 g) and cape turtle dove (streptopelia capicola, ∼148 g)] and australia [crest ... | 2016 | 27207640 |
| osteosarcoma of the tibiotarsus with possible pulmonary metastasis in a ring-necked dove (streptopelia risoria). | an unknown-age, adult female ring-necked dove (streptopelia risoria) was presented with an ulcerated mass on the medial side of the right tibiotarsus. radiographs revealed severe boney lysis with proliferative periosteal reaction. surgical amputation was performed at the level of the mid femur and histopathologic examination of the mass identified an osteosarcoma. at the 6-month recheck, the bird was in good condition with no evidence of tumor regrowth or metastasis; however, at 8 months, the do ... | 2014 | 24881154 |
| male territorial vocalizations and responses are decoupled in an avian hybrid zone. | a core area of speciation research concerns the coevolution of species-specific signals and the selective sensitivity to such signals. signals and responses to them should be tuned to each other, to be effective in intraspecific communication. hybrid zones are ideal to study the presence of such 'behavioural coupling' and the mechanisms governing it, and this has rarely been done. our study examines acoustic signals of males and their response to them in the context of territorial interactions i ... | 2008 | 18508751 |
| gastrointestinal disease associated with non-albicans candida species in six birds. | a non-albicans candida species was identified in 6 birds exhibiting clinical signs associated with gastrointestinal disease. the clinical disease signs noted in these 6 birds included diarrhea, regurgitation, and melena, and were considered concurrent or identified secondary to other comorbidities. candida glabrata was identified in a yellow-naped amazon parrot (amazona auropalliata), a ring-necked dove (streptopelia capicola), a blue-and-gold macaw (ara ararauna), and 2 cockatiels (nymphicus ho ... | 2019 | 31833310 |
