| sampling and isolation of cryptococcus neoformans from indoor air with the aid of the reuter centrifugal sampler (rcs) and guizotia abyssinica creatinine agar. a contribution to the mycological-epidemiological control of cr. neoformans in the fecal matter of caged birds. | in february and march 1984, cryptococcus neoformans was detected in the manure and ambient air of a volery in the berlin zoo in which a palm cockatoo (probosciger aterrimus) was kept. both times, 5 colony-forming units of cr. neoformans could be isolated on the differential medium, guizotia abyssinica creatinine agar, from 40 1 of air aspirated by the reuter centrifugal sampler (rcs). the absence of a concurrent growth of moulds was found to be of special importance for the optimal isolation of ... | 1985 | 3895777 |
| feather mites of the genera <i>dubininia</i> and <i>cacatualges</i> (acari: xolalgidae) associated with parrots (aves: psittaciformes) of the old world. | this paper gives a systematic revision of feather mites of the genera dubininia vassilev, 1958 and cacatualges dabert, badek and skoracki, 2007 (xolalgidae: ingrassiinae) associated with parrots (aves: psittaciformes) of the old world. five new species are described: cacatualges probosciger sp. n. from probosciger aterrimus (gmelin) (cacatuidae) from new guinea, dubininia charmosynae sp. n. from charmosyna pulchella gray gr (psittaculidae) from new guinea, d. micropsittae sp. n. from micropsitta ... | 2017 | 28610269 |
| tool-assisted rhythmic drumming in palm cockatoos shares key elements of human instrumental music. | all human societies have music with a rhythmic "beat," typically produced with percussive instruments such as drums. the set of capacities that allows humans to produce and perceive music appears to be deeply rooted in human biology, but an understanding of its evolutionary origins requires cross-taxa comparisons. we show that drumming by palm cockatoos (probosciger aterrimus) shares the key rudiments of human instrumental music, including manufacture of a sound tool, performance in a consistent ... | 2017 | 28782005 |
| the genome sequence of parrot bornavirus 5. | although several new avian bornaviruses have recently been described, information on their evolution, virulence, and sequence are often limited. here we report the complete genome sequence of parrot bornavirus 5 (pabv-5) isolated from a case of proventricular dilatation disease in a palm cockatoo (probosciger aterrimus). the complete genome consists of 8842 nucleotides with distinct 5' and 3' end sequences. this virus shares nucleotide sequence identities of 69-74 % with other bornaviruses in th ... | 2015 | 26403158 |
| ultrastructural, protein composition, and antigenic comparison of psittacine beak and feather disease virus purified from four genera of psittacine birds. | psittacine beak and feather disease (pbfd) virus, was purified from diseased tissues of a lesser sulphur-crested cockatoo (cacatua sulphurea), a black palm cockatoo (probosiger aterrimus), a red-lored amazon parrot (amazona autumnalis), and a peach-faced lovebird (agapornis roseicollis). the histopathology of diseased feathers and follicular epithelium from the different species was compared; basophilic intranuclear inclusion bodies were identified in the follicular epithelium and intracytoplasm ... | 1990 | 2338723 |
| cryptococcus neoformans in fecal matter of birds kept in cages--control of cr. neoformans habitats. | the occurrence of cryptococcosis in predamaged persons in whom the fecal matter of caged birds had been suspected as the source of infection has led to the present investigation. in the excreta of only four out of a total of 142 bird species kept by the berlin zoological gardens, cryptococcus neoformans could be demonstrated with the aid of guizotia abyssinica creatinine agar: twany frogmouth (podargus strigoides, g. eulenschwalm); palm cockatoo (probosciger aterrimus, g. arakakadu); military ma ... | 1984 | 6377755 |
| the evolutionary history of cockatoos (aves: psittaciformes: cacatuidae). | cockatoos are the distinctive family cacatuidae, a major lineage of the order of parrots (psittaciformes) and distributed throughout the australasian region of the world. however, the evolutionary history of cockatoos is not well understood. we investigated the phylogeny of cockatoos based on three mitochondrial and three nuclear dna genes obtained from 16 of 21 species of cacatuidae. in addition, five novel mitochondrial genomes were used to estimate time of divergence and our estimates indicat ... | 2011 | 21419232 |
| molecular techniques for sex identification of captive birds. | many avian species are considered sexually monomorphic. in monomorphic bird species, especially in young birds, sex is difficult to identify based on an analysis of their external morphology. accurate sex identification is essential for avian captive breeding and evolutionary studies. methods with varying degrees of invasiveness such as vent sexing, laparoscopic surgery, steroid sexing, and chromosome inspection (karyotyping) are used for sex identification in monomorphic birds. this study aimed ... | 2019 | 31749589 |
| unrewarded object combinations in captive parrots. | in primates, complex object combinations during play are often regarded as precursors of functional behavior. here we investigate combinatory behaviors during unrewarded object manipulation in seven parrot species, including kea, african grey parrots and goffin cockatoos, three species previously used as model species for technical problem solving. we further examine a habitually tool using species, the black palm cockatoo. moreover, we incorporate three neotropical species, the yellow- and the ... | 2014 | 25984564 |
| quill mites of the family syringophilidae (acariformes: prostigmata) associated with cockatoos (psittaciformes: cacatuidae). | quill mites of the family syringophilidae (acariformes: prostigmata: cheyletoidea) parasitizing cockatoos (psittaciformes: cacatuidae) are reviewed. three new species are described: neoaulobia cacatui sp. nov. from the yellow-tailed black-cockatoo calyptorhynchus funereus (type host) in australia and the palm cockatoo probosciger aterrimus in papua new guinea, lawrencipicobia calyptorhyncha sp. nov. from the glossy black-cockatoo calyptorhynchus lathami in australia, and lawrencipicobia sulphure ... | 2019 | 31716476 |
