Hirundo Rustica, 1st-winter - Pak Thale, Thailand
The bird genus ''Hirundo'' is a group of passerines in the family Hirundinidae (swallows and martins). The genus name is Latin for a swallow. These are the typical swallows, including the widespread barn swallow. Many of this group have blue backs, red on the face and sometimes the rump or nape, and whitish or rufous underparts. With fifteen species this genus is the largest in its family. Taxonomy The genus ''Hirundo'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The genus name is the Latin word for a swallow. Linnaeus included eight species in the genus and of these William Swainson designated the barn swallow (''Hirundo rustica'') as the type species. Extant species The genus contains fifteen species. The linear sequence is based on two molecular phylogenetic studies published in 2005 and 2018. Extinct species There are at least two fossil species included in this genus: *†''Hirundo gracilis'' (late Mioce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leech
Leeches are segmented parasitic or predatory worms that comprise the subclass Hirudinea within the phylum Annelida. They are closely related to the oligochaetes, which include the earthworm, and like them have soft, muscular segmented bodies that can lengthen and contract. Both groups are hermaphrodites and have a clitellum, but leeches typically differ from the oligochaetes in having suckers at both ends and in having ring markings that do not correspond with their internal segmentation. The body is muscular and relatively solid, and the coelom, the spacious body cavity found in other annelids, is reduced to small channels. The majority of leeches live in freshwater habitats, while some species can be found in terrestrial or marine environments. The best-known species, such as the medicinal leech, ''Hirudo medicinalis'', are hematophagous, attaching themselves to a host with a sucker and feeding on blood, having first secreted the peptide hirudin to prevent the blood from c ...

Pied-winged Swallow (Hirundo Leucosoma)
The pied-winged swallow (''Hirundo leucosoma'') is a species of bird in the family Hirundinidae. It has distinctive steel-blue upperparts with white wing patches. It is native to parts of West Africa. Taxonomy The pied-winged swallow was described by the English ornithologist William Swainson in 1837 who introduced its current binomial name ''Hirundo leucosoma''. The specific epithet combines the Ancient Greek words ''leukos'', "white" and ''sōma, sōmatos'', "body". The species is monotypic. Evolutionarily, the pied-winged swallow occupies a basal position within the clade of ''Hirundo'' swallows and is most closely related to the pearl-breasted swallow (''Hirundo dimidiata''). Description The pied-winged swallow is about long with glossy steel-blue wings and head. Most of the underside of the bird is white, with additional white patches found on special wing feathers. The tail is also steel-blue, but has green reflections. Females and juveniles typically have shorter ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-throated Swallow
The white-throated swallow (''Hirundo albigularis'') is a small bird in the swallow family. It is a common species, found in southern Africa, which has benefited from the increased nesting opportunities presented by the construction of bridges and dams. Description The white-throated swallow is 14–17 cm long. It has glossy dark blue upperparts and a bright chestnut crown. A dark blue-black breast band separates the white throat from the greyish white underparts and underwing coverts. The upper wings, underwing flight feathers and forked tail are blackish-blue, but the undertail has white patches near the feather tips. The white throat and blackish breast band are distinctions from similar ''Hirundo'' species. The outer feathers are slightly longer in the male than the female. Juveniles are duller than the adult, with shorter outer tail feathers and a browner crown. The call is a mix of warbles and twitters. Distribution and habitat The swallow breeds in southern Africa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Welcome Swallow
The welcome swallow (''Hirundo neoxena'') is a small passerine bird in the swallow family. It is a species native to Australia and nearby islands, and self-introduced into New Zealand in the middle of the twentieth century. It is very similar to the Pacific swallow with which it is often considered conspecific. This species breeds in southern and eastern Australia in a variety of habitats, mostly in open areas, man-made clearings or urban environments, but not desert or dense forest. Eastern populations are largely migratory, wintering in northern Australia. Western birds and those in New Zealand are mainly sedentary. Taxonomy The welcome swallow was first described by John Gould in ''The Birds of Australia'' as a member of the genus ''Hirundo'', but the first publication is often incorrectly given as in the ''Proceedings of the Zoological Society of London''. Both its species name and common name refer to people welcoming its return as a herald of spring in southern parts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hill Swallow
The hill swallow (''Hirundo domicola'') is a small passerine bird in the swallow family. It breeds in southern India and Sri Lanka. It is resident apart from some local seasonal movements. This bird is associated with coasts, but is increasingly spreading to forested uplands. It was formerly considered to be a subspecies of the Pacific swallow. Description This species is a small swallow at . It has a blue back with browner wings and tail, a red face and throat, and dusky underparts. It differs from the barn swallow and the closely related welcome swallow in its shorter and less forked tail. Behaviour Reproduction The hill swallow builds a neat cup-shaped nest, constructed with mud pellets collected in the beak, under a cliff ledge or on man-made structures such as a building, bridge or tunnel. The nest is lined with softer material, and the clutch is up to four eggs. Detailed studies on the breeding ecology of the species were conducted in Silent Valley National Park ...

Pacific Swallow
The Pacific swallow (''Hirundo tahitica'') is a small passerine bird in the swallow family. It breeds in tropical southern Asia and the islands of the south Pacific. It is resident apart from some local seasonal movements. This bird is associated with coasts, but is increasingly spreading to forested uplands. The hill swallow and the welcome swallow were formerly considered conspecific. This species is a small swallow at 13 cm. It has a blue-black back and crown with browner wings and tail, a red face and throat, and dusky underparts. It differs from the barn swallow and the closely related welcome swallow in its shorter and less forked tail. The Pacific swallow builds a neat cup-shaped nest, constructed with mud pellets collected in the beak, under a cliff ledge or on man-made structures such as a building, bridge or tunnel. The nest is lined with softer material, and the clutch is two to three eggs. It is similar in behaviour to other aerial insectivores, such as other s ...

Pearl-breasted Swallow
The pearl-breasted swallow (''Hirundo dimidiata'') is a small swallow. Description The pearl-breasted swallow is 13–14 cm long. It has glossy blue upperparts and grey-white underparts. The upper wings, underwing flight feathers and forked tail are blackish-blue. The underwing coverts are a darker shade of grey-white. The lack of white in the tail is a distinction from similar ''Hirundo'' species. The outer feathers are slightly longer in the male than the female. Juveniles are duller and browner than the adult, with shorter outer tail feathers. The northern subspecies, ''H. d. marwitzi'' is darker and smaller than nominate ''H. d. dimidiata'', but the differences are small, and the species may be monotypic. Distribution and habitat The pearl-breasted swallow breeds in southern Africa from Angola, southern Congo and Tanzania southwards. It is sparsely distributed, but can be locally common. It is partially migratory with many birds from the southwest of South Africa winter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
