| salmonella enteritidis infection in two species of psittaciformes. | in 1990, salmonella enteritidis phage type 4 was recovered from two young (less than 20-week-old) lilac-crowned amazon parrots (amazona finschi schlater), one in tennessee and one in kansas. the parrot from tennessee was treated for a plugged naris and anorexia before the s. enteritidis infection was discovered. the parrot from kansas exhibited signs of septicemia and died within 24 hours of examination. an apparently healthy green-cheeked conure (pyrrhura molinae) on the same premises as the pa ... | 1992 | 1417612 |
| contextual flexibility in the vocal repertoire of an amazon parrot. | understanding the role of avian vocal communication in social organisation requires knowledge of the vocal repertoire used to convey information. parrots use acoustic signals in a variety of social contexts, but no studies have evaluated cross-functional use of acoustic signals by parrots, or whether these conform to signal design rules for different behavioural contexts. we statistically characterised the vocal repertoire of 61 free-living lilac-crowned amazons (amazona finschi) in nine behavio ... | 2016 | 27570534 |
| fatty acid profiles of crop contents of free-living psittacine nestlings and of commercial hand-feeding formulas. | research on psittacine nutrition is limited, and nestling requirements are poorly understood. this study analysed fatty acid (fa) profiles of crop contents of free-living scarlet macaws (ara macao, n = 18), red-and-green macaws (ara chloropterus, n = 5), cuban parrots (amazona leucocephala bahamensis, n = 27), lilac-crowned amazons (amazona finschi, n = 33) and thick-billed parrots (rhynchopsitta pachyrhyncha, n = 32). the same analysis was carried out on 15 commercial parrot hand-feeding formul ... | 2020 | 32974980 |
