| bacterial cholecystitis with cardiac and pulmonary dissemination in a blue-naped mousebird (urocolius macrourus). | a blue-naped mousebird (urocolius macrourus) was diagnosed by gross necropsy and histopathology as having a chronic, fibrosing bacterial cholecystitis. acute, severe, necrotizing pneumonia and myocarditis also were present with intralesional gram-negative bacteria. the bacteria within the lungs and heart were suspected to have spread from the biliary tract because of the pattern of distribution and similar gram-staining characteristics. enterobacter sp. and escherichia coli were cultured from th ... | 2000 | 10879929 |
| role of akt signaling pathway regulation in the speckled mousebird (colius striatus) during torpor displays tissue specific responses. | pronounced heterothermic responses are relatively rare among birds. along with taxa such as hummingbirds and caprimulgids, the order coliiformes (mousebirds) is known to possess the physiological capacity for torpor. during torpor, body temperature is greatly reduced and a bird becomes unresponsive to external stimuli until ambient temperatures return to more favorable conditions. under such conditions, these birds are forced to rely only on their internal fuel storage for energy and show great ... | 2020 | 32871209 |
| a new genus of quill mites of the family syringophilidae (acari: cheyletoidea) associated with mousebirds (aves: coliiformes). | a new monotypic genus colisyringophilus n. g. is established for c. tanzanicus n. sp., quill mites parasitising two mouse bird species from tanzania, colius striatus gmelin and urocolius macrourus (linnaeus). this new genus is closely related to neoaulobia fain, bochkov & mironov, 2000, but differs from it by the following features: the stylophore is rounded posteriorly, the propodonotal shield is reduced to triangular sclerite bearing bases of setae vi and ve, the hysteronotal shield is absent, ... | 2013 | 23793495 |
| effects of tannins on fruit selection in three southern african frugivorous birds. | tannins are common secondary compounds in plant material and are known for their ability to bind to protein which reduces nitrogen availability in the diet. in fruits, these compounds are responsible for their astringency which is thought to result in reduced food intake. in this study, the repellent effects of tannins were examined in three species of frugivorous birds: red-winged starlings onychognathus morio, speckled mousebirds colius striatus and cape white-eyes zosterops virens. birds were ... | 2015 | 25522953 |
| digestive efficiencies of cape white-eyes (zosterops virens), red-winged starlings (onychognathus morio) and speckled mousebirds (colius striatus) fed varying concentrations of equicaloric glucose or sucrose artificial fruit diets. | digestive physiology is important for understanding the feeding behaviour of organisms. specifically, studies on the digestive physiology of frugivorous and nectarivorous birds are important for elucidating their preference patterns in the wild and the selective pressures they exert on fruit pulp and nectar. in this study, digesta transit times and digestive efficiencies of three species of birds, the cape white-eyes (zosterops virens), red-winged starlings (onychognathus morio) and speckled mou ... | 2016 | 27174647 |
| heterothermic responses in the speckled mousebird (colius striatus). | we investigated normothermic thermoregulation and heterothermic responses to restricted food in the speckled mousebird colius striatus, in the context of the widely accepted distinction between normothermia, rest-phase hypothermia, and torpor. normothermic thermoregulation differed from typical endothermic patterns in that rest-phase body temperature (tb) was not maintained with respect to a constant setpoint. instead, tb decreased during the course of the rest-phase, with the highest cooling ra ... | 2001 | 11585263 |
