survey of pathogens in threatened wild red-tailed amazon parrot (amazona brasiliensis) nestlings in rasa island, brazil.the red-tailed amazon parrot (amazona brasiliensis) is a threatened species of psittacine bird that inhabit coastal regions of brazil. in view of the threat of this species, the aim of this study was to perform a health evaluation in wild nestlings in rasa island, determining the prevalence of enterobacteria and infectious agents according to type of nest. blood samples were collected from 64 birds and evaluated for antibodies of chlamydia psittaci by commercial dot-blot elisa. cloacal and oroph ...201728629971
annual pattern of fecal corticoid excretion in captive red-tailed parrots (amazona brasiliensis).annual patterns of fecal corticoid excretion were analyzed in the threatened red-tailed parrot (amazona brasiliensis) in captivity. corticoid concentration over the 15 months of the study (mean +/- standard error, 12.6 +/- 0.32 ng g(-1), n = 585) was lowest around may (the southern fall), and greatest around september (late winter), just prior to their normal breeding period. corticoid excretion follows a seasonal pattern best explained by reproductive cycles rather than climate, although climat ...200818180929
hematologic and total plasma protein values in free-living red-tailed amazon parrot nestlings (amazona brasiliensis) in paraná state, brazil.the red-tailed amazon parrot (amazona brasiliensis) is an endangered psittacid species that is endemic in the south and southeast brazilian atlantic coastal region. hematologic evaluation is important to monitor the health of these birds, and information about laboratory values for this species is scarce. hematologic and total plasma protein profiles were determined for 33 free-living nestling parrots in paraná state, brazil. parrots were temporarily removed from the nest and manually restrained ...201526378664
polymorphic dna microsatellite markers for forensic individual identification and parentage analyses of seven threatened species of parrots (family psittacidae).the parrot family represents one of the bird group with the largest number of endangered species, as a result of habitat destruction and illegal trade. this illicit traffic involves the smuggling of eggs and animals, and the laundering through captive breeding facilities of wild-caught animals. despite the huge potential of wildlife dna forensics to determine with conclusive evidence illegal trade, current usage of dna profiling approaches in parrots has been limited by the lack of suitable mole ...201627688959
hematologic and biochemical reference intervals of free-living red-tailed amazon parrot (amazona brasiliensis) nestlings on rasa island, paraná, brazil.the red-tailed amazon parrot (amazona brasiliensis) is an endangered species of the psittaciformes. there is little information about hematologic and biochemical variables of this species.201627701767
hematologic and biochemical values of wild red-tailed amazon parrot (amazona brasiliensis) nestlings with abnormal clinical examination in rasa island, brazil.the red-tailed amazon parrot (amazona brasiliensis) is an endangered psittacine species, but little information is available about abnormal clinical findings and hematologic and biochemical values of this species, which are important for monitoring the health of this population. to determine hematologic and biochemical values for wild red-tailed parrot nestlings exhibiting abnormal clinical findings, 31 nestlings from the rasa island (paraná state, southern brazil) were physically restrained for ...201628107063
survey of toxoplasma gondii, neospora caninum and sarcocystis neurona antibodies in wild red-tailed amazon parrots (amazona brasiliensis).toxoplasma gondii, neospora caninum and sarcocystis neurona are obligate intracellular parasites within the phylum apicomplexa. the red-tailed amazon parrot (amazona brasiliensis) is a near-threatened species of psittacine that is endemic to the atlantic forest of brazil and has been designated as a bioindicator because of its sensitivity to environmental qualitative status and changes. the aim of this study was to evaluate the presence of antibodies against t. gondii, n. caninum and s. neurona ...202032049146
