macrorhynchos - Synonyms for macrorhynchos

Examples of "macrorhynchos"
"O. macrorhynchos" is of commercial interest to fisheries.
It was formerly considered a subspecies of the Guianan puffbird ("N. macrorhynchos"). The two differ markedly in bill-size ("N. hyperrhynchus" larger-billed than "N. macrorhynchos"), plumage (among other things, "N. hyperrhynchus" has less black to the flanks and more white to the forecrown than "N. macrorhynchos"), and voice. Consequently, the two were separated by SACC in 2004.
The eastern jungle crow ("Corvus macrorhynchos levaillantii") is a bird in the family Corvidae.
The Pacific spadenose shark ("Scoliodon macrorhynchos") is a species of requiem shark, in the family Carcharhinidae. It was once regarded as conspecific to the spadenose shark ("S. laticaudus").
The Guianan puffbird ("Notharchus macrorhynchos") is a species of puffbird in the family Bucconidae. It is found in forest and woodland in north-eastern South America (and named after The Guianas), in far eastern Venezuela, north-eastern Brazil, Guyana, Suriname and French Guiana. It formerly included the white-necked puffbird (now "N. hyperrhynchus") as a subspecies. The two differ markedly in bill size ("N. hyperrhynchus" larger-billed than "N. macrorhynchos"), plumage (among other things, "N. hyperrhynchus" has less black to the flanks and more white to the forecrown than "N. macrorhynchos"), and voice. Consequently, the two were separated by SACC in 2004. As presently defined, the Guianan puffbird is monotypic.
The black-and-red broadbill ("Cymbirhynchus macrorhynchos") is a species of bird in the broadbill family. It is monotypic within the genus Cymbirhynchus.
The jungle crow ("Corvus macrorhynchos"), is a widespread Asian species of crow. It is very adaptable and is able to survive on a wide range of food sources, making it capable of colonizing new areas, due to which it is often considered a nuisance, especially on islands. It has a large bill which is the source of its scientific name "macrorhynchos" (Ancient Greek for "large beak"), and it is sometimes known by the common names large-billed crow or thick-billed crow. It can also be mistaken for a raven. Johann Georg Wagler first described the species from a holotype obtained from Java in the year 1827
The classification of the Asian crows has been in a state of confusion. This species was described as "Corvus culminatus" by Colonel W. H Sykes based on a specimen from Pune. Eugene Oates considered this as a single species "Corvus macrorhynchos" in "The Fauna of British India, Including Ceylon and Burma". (1889), based on what had been concluded by Allan Octavian Hume based on the inability to see consistent differences in the specimens. W. E. Brooks had pointed out that the voice of the Himalayan species differed significantly apart from having longer tail. The second edition of "The Fauna of British India". (1922) by Stuart Baker considered "macrorhynchos" as a form restricted to Java and considered the Indian forms to be made up of three subspecies of the Australian raven "Corvus coronoides". Ernst Hartert looked at the colour of the base of the neck feather and grouped those that had grey bases into one group ("coronoides" ravens) and those that had white bases into the crow (southern) group and the northern forms including the Indian ones into "levaillantii" with nine subspecies. Ernst Mayr reshuffled the group in 1940. Hugh Whistler and Norman Boyd Kinnear decided that the three Indian forms "culminatus", "intermedius" and "macrorhychos" were subspecies "Corvus macrorhynchos". Charles Vaurie made another revision in 1954. Salim Ali and Dillon Ripley in the "Handbook of the Birds of India and Pakistan" used "macrorhynchos" under which they placed four forms "culminatus", "intermedius", "levaillantii" and "tibetosinensis".
Ophisurus macrorhynchos is an eel in the family Ophichthidae (worm/snake eels). It was described by Pieter Bleeker in 1853. It is a marine, temperate water-dwelling eel which is known from the Indo-Western Pacific and Atlantic Ocean. Males can reach a maximum total length of , but more commonly reach a TL of .
The Asian koel is a brood parasite, and lays its single egg in the nests of a variety of birds, including the jungle crow, and house crow. In Sri Lanka before 1880 it was only known to parasitize the jungle crow, later shifting to the house crow. A study in India found 5% of "Corvus splendens" and 0.5% of "Corvus macrorhynchos" nests parasitized.
Spotted nutcrackers are not migratory, but will erupt out of range when a cone crop failure leaves them short of a food supply, the thin-billed eastern race "macrorhynchos" being the more likely to do this. Britain records very sporadic vagrants, but in 1968 over 300 nutcrackers visited Britain as part of a larger irruption into western Europe, probably due to a spell of early cold weather in Siberia.
Flowers are 8 cm long and in pairs, creamy yellow and sweet scented. Pods are about 6.5 x 1.5 cm, flat, cartilaginous, glaucous, transversely veined with undulate margins. They are initially straight but on maturity become twisted with irregular spirals. Seeds are transversely held in the pod, broadly ovate to elliptical, about 4-6 x 3–4 mm. At Kozhikode (Kerala, India), flocks of jungle crow (Corvus macrorhynchos), grey-headed myna (Sturnia malabarica) and red whiskered bulbul (Pycnonotus jocosus) have been observed to feed on the seeds with the aril that are exposed when the pods are split. These birds also probably help in dispersal of seeds.
The predators most affecting the reproductive success of the fairy pitta are snakes, followed by mammals such as macaques, cats and weasels. The raiding of nests by jungle crows ("Corvus macrorhynchos") and cat snakes during breeding season has also been reported frequenelty. During migrations, the bird is exposed to danger from falcons. The rate at which adult fairy pittas return from the wintering grounds appears to be 16-26%; most casualties happening on the bird’s northward migrating and during breeding seasons from May to July. Fewer birds are lost during the autumn migration in October. Another cause of mortality is window strikes. As for many other species of bird, casualties from human-bird interaction are identified as a leading cause of decline in the fairy pitta.
The Indian jungle crow ("Corvus macrorhynchos culminatus") is usually considered a subspecies of jungle crow found in the plains of India where it is very common and readily distinguished from the house crow which has a grey neck. Some authorities consider it to be a distinct species. Often grouped along with other crow species in the region, it differs in its voice from the large-billed crow found in the higher elevations of the Himalayas and the eastern jungle crow ("Corvus levaillantii") overlaps in the eastern part of its range. In appearance it cannot be easily distinguished from either of these species although the plumage tends to be more uniformly glossed in purple and has a longer bill with a fine tip and an arched culmen. The Himalayan species has a slightly wedge-shaped tail unlike the rounded tail of the Indian jungle crow.
Greater coucals are monogamous, and the courtship display involves chases on the ground and the male brings food gifts for the female. The female lowers her tail and droops her wings to signal acceptance. The nest is built mostly by the male over about three to eight days. The nest is a deep cup with a dome in dense vegetation inside tangles of creepers, bamboo clump or "Pandanus" crowns. They can be built as high as 6m above the ground and the typical clutch is 3–5 eggs. The eggs (of size 36–28 mm weighing 14.8 g ) are chalky white with a yellow glaze when laid that wears off. Both the male and the female take part in nest building. They lay 2 to 4 eggs that hatch after 15–16 days of incubation. The chicks take 18–22 days to fledge. A study in southern India found that 77% of the eggs hatched and 67% fledged. Nests with eggs were sometimes abandoned or marauded by the jungle crow "Corvus macrorhynchos".
Eggs are often destroyed at the nest by jungle ("Corvus macrorhynchos") and house crows ("C. splendens"). In Australia, predators of young birds include the dingo ("Canis dingo") and fox ("Vulpes vulpes") while brahminy kites ("Haliastur indus") have been known to take eggs. Removal of eggs by farmers (to reduce crop damage) or children (in play), or by migrant labourers for food or opportunistic egg collection during trips to collect forest resources are prominent causes of egg mortality. Between 31 and 100% of nests with eggs can fail to hatch eggs for these reasons. Chicks are also prone to predation (estimated at about 8%) and collection at the nest, but more than 30% die of unknown reasons. Breeding success (percentage of eggs hatching and surviving to fledging stage) has been estimated at about 20% in Gujarat and 51–58% in south-western Uttar Pradesh. In areas where farmers are tolerant, nests in flooded rice fields and those in wetlands have similar rates of survival. Pairs that nest later in the season have a lower chance of raising chicks successfully, but this improves when territories have more wetlands. Nest success for 96 sarus nests that were protected by locals during 2009–2011 via a payment-for-conservation program was 87%. More pairs are able to raise chicks in years with higher total rainfall, and when territory quality was undisturbed due to increased farming or development. Permanent removal of pairs from the population due to developmental activities caused reduced population viability, and was a far more important factor relative to breeding success due to changes in total annual rainfall.
