| porphyrins and pheomelanins contribute to the reddish juvenal plumage of black-shouldered kites. | porphyrins are a widespread group of pigments in nature, but, contrary to melanins and carotenoids, their occurrence as plumage colorants seems to be anecdotal and their function, if any, is unknown. using thin-layer chromatography and high pressure liquid chromatography, we have found coproporphyrin iii, the same porphyrin type previously reported in owls, in the plumage of nestling black-shouldered kites (elanus caeruleus). the first plumage grown at the nest in this species includes reddish-b ... | 2009 | 19351566 |
| characterization of the atypical karyotype of the black-winged kite elanus caeruleus (falconiformes: accipitridae) by means of classical and molecular cytogenetic techniques. | the karyotype of the black-winged kite (elanus caeruleus), a small diurnal raptor living in africa, asia and southern europe, was studied with classical (g-, c-, r-banding, and ag-nor staining) and molecular cytogenetic methods, including primed in-situ labelling (prins) and fluorescence in-situ hybridization (fish) with telomeric (ttaggg) and centromeric dna repeats. the study revealed that the genome size, measured by flow cytometry (3.1 pg), is in the normal avian range. however, the black-wi ... | 2003 | 12906130 |
| unilateral lentectomy in a black-shouldered kite. | an extracapsular lentectomy was performed on an adult black-shouldered kite (elanus caeruleus) presented with a history of head trauma resulting in a unilateral cataract and ventro-medial synechia of the right eye. one week post-operatively, the eye contents were clear and the iris appeared normal. the bird was released into a flight cage 3.5 weeks post-operatively. two weeks later it was presented with a ruptured right cornea as a result of trauma and enucleation was recommended. | 1990 | 2286999 |
| frequent detection of anticoagulant rodenticides in raptors sampled in taiwan reflects government rodent control policy. | anticoagulant rodenticides (ars) are known to cause extensive secondary exposure in top predators in europe and north america, but there remains a paucity of data in asia. in this study, we collected 221 liver samples from 21 raptor species in taiwan between 2010 and 2018. most birds were recovered from rescue organizations, but some free-ranging individuals were obtained from bird-strike prevention measures at airports. ars were detected in 10 species and more than half of the total samples. co ... | 2019 | 31326797 |
| morphological and molecular characterization of avian trypanosomes in raptors from thailand. | from september 2012 to may 2018, blood samples from 364 raptors (mostly adults) were collected and screened for trypanosomes and haemosporidians by microscopic examination and nested polymerase chain reactions (pcr). trypanosoma spp. were identified in 15 birds from eight different species. light microscopy revealed 14 cases of infection with trypanosoma cf. corvi, including one each in black-shouldered kite (elanus caeruleus, n = 49), brahminy kite (haliastur indus, n = 50), and spotted owlet ( ... | 2019 | 31230161 |
| quantitative and qualitative characteristics of blood cells in black-shouldered, brahminy, and black kites. | black-shouldered kites (bsk, elanus caeruleus), brahminy kites (brk, haliastur indus), and black kites (bk, milvus migrans govinda) are medium-sized hawks found in thailand, and little is known about the hematology of these three kite species. | 2019 | 30667520 |
| nesting biology of black-shouldered kite (elanus caeruleus) in oil palm landscape in carey island, peninsular malaysia. | black-shouldered kite (elanus caeruleus) is a well-known raptor that inhabits open areas such as oil palm plantation or paddy field. to determine preferable habitat and nesting site of black-shouldered kite in oil palm landscape, we conducted a study on black-shouldered kite's nesting biology in carey island, selangor, malaysia. we divided the island into six types of habitat and conducted road-side count of black-shouldered kite from april 2009 to february 2011. whenever the black-shouldered ki ... | 2018 | 29686514 |
