Over 350 species of birds make up the order Psittaciformes; many of these are maintained in captive environments. Malnutrition is commonly diagnosed in captive psittacine birds; therefore, providing nutritionally adequate diets must be a primary concern. This review integrates quantitative information on the dietary habits and nutritional requirements of psittacine birds to facilitate the formu...

Quantifying a relationship between heart rate (f(H)) and rate of oxygen consumption (V(O(2))) allows the estimation of V(O(2)) from f(H) recordings in free-ranging birds. It has been proposed that this relationship may vary throughout an animal's annual cycle, due to changes in physiological status. Barnacle geese, Branta leucopsis, provide an ideal model to test this hypothesis, as they exhibi...

The loss of biodiversity following fragmentation and degradation of habitat is a major issue in conservation biology. As competition for resources increases following habitat loss and fragmentation, severe population declines may occur even in common, highly mobile species; such demographic decline may cause changes within the population structure of the species. The regent honeyeater, Anthocha...

Abstract We measured fatty acids, minerals, and fat-soluble nutrients in liver tissues from greater prairie-chickens Tympanuchus cupido pinnatus as an ecological dietary surrogate for endangered Attwater's T. c. attwateri investigated differences associated with captive (nonreleased raised; n = 4), wild (n 12), combination (released 5) diets. In general, we found more variability across all aci...

Avian mycobacteriosis is an important disease which affects companion, captive exotic, wild and domestic birds. The disease is most commonly caused by Mycobacterium avium and Mycobacterium genavense. Lesions are typically found in the liver and gastrointestinal tract, although many other organ systems can potentially be affected. The authors review those species of Mycobacterium reported to aff...

OBJECTIVE To report the first Ilheus arboviruses isolated from wild birds and analyze its public health impact. METHODS Wild birds and mammals were captured using mist nets and Tomahawk traps, respectively. Blood samples were drawn from these animals and inoculated intracerebrally in Swiss suckling mice found in the Parque Ecológico do Tietê, Brazil. The isolates were identified by serologica...

Aroclor 1248 was fed to captive screech owls (Otus asio) at the rate of three ppm in the diet to determine if reproductive effects such as fewer eggs per clutch, lower hatchability, malformation of the chicks, or higher mortality rates of chicks would appear in this raptorial species as they did in chickens. There were no effects on eggshell thickness, number of eggs laid, young hatched, and yo...

Accepted: 19/02/2015 Abstract Aspergillosis is an infectious, non-contagious fungal disease of wild and domestic birds caused by fungus Aspergillus species. It is characterized by primary involvement of respiratory tract, formation of yellow cheesy plaques and hard nodular masses in the lungs and air sacs, though other organs may also be generally involved. This fungal disease is of economic im...

Further to releases of blue ducks into Egmont National Park in 1987, 1989 and 1991, a continuation of efforts to establish a population in the Park has begun. Eleven captive-raised and four wild-caught birds were translocated to the park in December 1999 and January 2000. All birds were fitted with harness transmitters, and survival and dispersal was monitored. In addition, data was collected o...

The first survey on the incidence of beak and feather disease virus (BFDV) and avian polyomavirus (APV) among the captive psittacine birds in Poland was presented in this study. Samples were collected between 2006 and 2009. A total number of 751 symptom–free birds from 31 genera and 59 species were tested for BFDV and APV by means of a PCR assay. BFDV was found in 25.3% and APV in 22.24% of the...
