| 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 |
| the endocast of the night parrot (pezoporus occidentalis) reveals insights into its sensory ecology and the evolution of nocturnality in birds. | the night parrot (pezoporus occidentalis) is a rare, nocturnal parrot species that has largely escaped scientific investigation due to its behaviour and habitat preferences. recent field studies have revealed some insights into night parrot behaviour, but nothing is known of its sensory abilities. here, we used μct scans of an intact night parrot specimen to determine if its visual system shares similarities with other nocturnal species. the endocast of the night parrot revealed relatively small ... | 2020 | 32518353 |
| detection of ground parrot vocalisation: a multiple instance learning approach. | ground parrot vocalisation can be considered as an audio event. test-based diverse density multiple instance learning (tb-dd-mil) is proposed for detecting this event in audio files recorded in the field. the proposed method is motivated by the advantages of multiple instance learning from incomplete training data. spectral features suitable for encoding the vocal source information of the ground parrot vocalization are also investigated. the proposed method was benchmarked against a dataset col ... | 2017 | 28964088 |
