crows break off live camphor twigs: an avian disturbance effect on plants. | birds are usually considered beneficial partners for plants, acting as predators on herbivorous insects, pollinators and seed dispersal agents. however, in an urban area of central japan, birds break off large quantities of live camphor tree (cinnamomum camphora) twigs in winter. this loss of vegetative parts was examined quantitatively to estimate the impact on the trees. i also observed bird foraging behaviour to determine the species involved and the possible reasons underlying this destructi ... | 2009 | 19796368 |

ganglion cell density and oil droplet distribution in the retina of brown-eared bulbul (hypsipetes amaurotis) [corrected]. | this study was intended to determine the number and density of both retinal ganglion cells and the oil droplets of cone photoreceptor cells in brown-eared bulbul (hypsipetes amaurotis). for this study birds were killed with proper dose of anesthetic (pentobarbital, 30 mg/kg), and the eyes were removed from the orbital cavity to isolate the retina. for the ganglion cell study retinal whole-mount specimens were prepared and stained with 0.1% cresyl violet. the different types of oil droplets were ... | 2008 | 19159352 |
morphological and histochemical study of the nasal cavity and fused olfactory bulb of the brown-eared bulbul, hysipetes amaurotis. | the brown-eared bulbul (hysipetes amaurotis) is commonly found in japan where it is regarded as a harmful bird that causes damage to agricultural products. few studies have investigated the sensory apparatus of this bird, and consequently little is known of the sensory modalities it uses. here we analyzed the anatomical and histological properties of the nasal cavity and olfactory bulb (ob) of the bulbul in order to investigate the functional level of olfaction in this species. although both ant ... | 2009 | 19832684 |
origin of japanese white-eyes and brown-eared bulbuls on the volcano islands. | the ogasawara archipelago comprises two groups of oceanic islands: the bonin islands, formed in the paleogene, and the volcano islands, formed in the quaternary. these groups are located within a moderate distance (ca. 160-270 km) of one another; thus, most land bird species are not distinguished as different subspecies. two land birds, however, show unusual distribution. the japanese white-eyes zosterops japonicus originally inhabited only the volcano islands, but has been introduced to the bon ... | 2016 | 27032679 |
genetic identification for prey birds of the endangered peregrine falcon (falco peregrinus). | to reveal the dietary ecology of the peregrine falcon (falco peregrinus), we conducted a molecular analysis for mitochondrial genes (coi and cytb) to identify the prey species collected from a feeding place found on sasu island, south korea. the results from noninvasive genetic analysis showed that the sequences obtained came from nine species of birds (cuculus canorus, eurystomus orientalis, limosa limosa, microscelis amaurotis, oriolus chinensis, phasianus colchicus, sterna hirundo, streptopel ... | 2017 | 28071972 |
susceptibility of wild passerines to subtype h5n1 highly pathogenic avian influenza viruses. | highly pathogenic avian influenza (hpai) viruses of the h5n1 subtype have spread throughout many areas of asia, europe and africa, and numerous cases of hpai outbreaks in domestic and wild birds have been reported. although recent studies suggest that the dissemination of h5n1 viruses is closely linked to the migration of wild birds, information on the potential for viral infection in species other than poultry and waterfowl is relatively limited. to investigate the susceptibility of terrestrial ... | 2015 | 26274569 |

isolation and genomic characterization of a novel orthoreovirus from a brown-eared bulbul (hypsipetes amaurotis) in japan. | five species, mammalian orthoreovirus, avian orthoreovirus (arv), nelson bay orthoreovirus (nbv), baboon orthoreovirus and reptilian orthoreovirus, have been identified in the genus orthoreovirus. their genomes each consist of 10 dsrna segments. a novel orthoreovirus was isolated from the haemorrhagic intestine of a dead brown-eared bulbul (hypsipetes amaurotis) in japan. the virus formed syncytia in caco-2 and vero cells. electron microscopy revealed non-enveloped capsids of ~70 nm diameter, wh ... | 2015 | 25740958 |

phylogenetic comparison of leucocytozoon spp. from wild birds of japan. | eight species of japanese birds were found to be infected with leucocytozoon species using microscopic analysis. we used pcr and sequence analysis of the mitochondrial cytochrome b gene (cyt b) to compare the genetic background among these detected protozoa species. in 20 individuals of 22 samples, a single amplified band was detected from 6 of 8 bird species; 9 japanese rock ptarmigans (lagopus mutus japonicus), 4 large-billed crows (corvus macrorhynchos), 2 carrion crows (c. corone), 2 scops o ... | 2007 | 17283401 |

determination of temperate bird-flower interactions as entangled mutualistic and antagonistic sub-networks: characterization at the network and species levels. | most network studies on biological interactions consider only a single interaction type. however, individual species are simultaneously positioned in various types of interactions. the ways in which different network types are merged and entangled, and the variations in network structures between different sympatric networks, require full elucidation. incorporating interaction types and disentangling complex networks is crucial, because the integration of various network architectures has the po ... | 2014 | 24372171 |
