Koel
The true koels, ''Eudynamys'', are a genus of cuckoos from Asia, Australia and the Pacific. They are large sexually dimorphic cuckoos that eat fruits and insects and have loud distinctive calls. They are brood parasites, laying their eggs in the nests of other species. Taxonomy The genus ''Eudynamys'' was introduced in 1827 by the English naturalists Nicholas Vigors and Thomas Horsfield. The name combines the Ancient Greek ''eu'' meaning "fine" with ''dunamis'' meaning "power" or "strength". The type species was designated as the Pacific koel by George Robert Gray in 1840. A molecular genetic study by Sorenson and Payne (2005) found that the closest relative of ''Eudynamys'' is the dwarf koel (''Microdynamis parva''), and beyond that the thick-billed cuckoo (''Pachycoccyx audeberti''). They found that the long-tailed cuckoo (''Urodynamis taitensis'') of New Zealand and the Pacific, which had earlier been placed in ''Eudynamys'' as ''E. taitensis'' and sometimes called the ...

Eudynamys Scolopaceus
The Asian koel (''Eudynamys scolopaceus'') is a member of the cuckoo order of birds, the Cuculiformes. It is found in the Indian Subcontinent, China, and Southeast Asia. It forms a superspecies with the closely related black-billed koels, and Pacific koels which are sometimes treated as subspecies. The Asian koel like many of its related cuckoo kin is a brood parasite that lays its eggs in the nests of crows and other hosts, who raise its young. They are unusual among the cuckoos in being largely frugivorous as adults. The name ''koel'' is echoic in origin with several language variants. The bird is a widely used symbol in Indian and Nepali poetry. Taxonomy In 1747 the English naturalist George Edwards included an illustration and a description of the Asian koel in the second volume of his ''A Natural History of Uncommon Birds''. He used the English name "The Brown and Spotted Indian Cuckow". Edwards based his hand-coloured etching on a specimen from Bengal that belonged ...

Pacific Koel
The Pacific koel (''Eudynamys orientalis''), also known as the eastern koel or formerly Common Koel, is a species of cuckoo in the family Cuculidae. In Australia, it is colloquially known as the ''rainbird'' or ''stormbird'', as its call is usually more prevalent before or during stormy weather. Taxonomy It has often been considered conspecific with the Asian koel, Asian and black-billed koels, but they are increasingly treated as a separate species. Alternatively, the population breeding in Australia has been considered a separate species, the Australian Koel (''Eudynamys cyanocephalus''), with the remaining taxa then considered subspecies of the Asian koel. Distribution and habitat The Pacific koel is found in forest, woodland, plantations and gardens from Wallacea east to the Solomon Islands and south to northern and eastern Australia. The Pacific koel has not been rated by IUCN, but the Australian Koel (here included in the Pacific koel) is considered to be of Least Concern. ...

Cuckoo
Cuckoos are birds in the Cuculidae family, the sole taxon in the order Cuculiformes . The cuckoo family includes the common or European cuckoo, roadrunners, koels, malkohas, couas, coucals and anis. The coucals and anis are sometimes separated as distinct families, the Centropodidae and Crotophagidae respectively. The cuckoo order Cuculiformes is one of three that make up the Otidimorphae, the other two being the turacos and the bustards. The family Cuculidae contains 150 species which are divided into 33 genera. The cuckoos are generally medium-sized slender birds. Most species live in trees, though a sizeable minority are ground-dwelling. The family has a cosmopolitan distribution; the majority of species are tropical. Some species are migratory. The cuckoos feed on insects, insect larvae and a variety of other animals, as well as fruit. Some species are brood parasites, laying their eggs in the nests of other species and giving rise to the metaphor ''cuckoo's egg' ...

Eudynamys Melanorhynchus
The black-billed koel (''Eudynamys melanorhynchus'') is a species of cuckoo in the family Cuculidae. It is endemic to forest and woodland on the Indonesian islands of Sulawesi, Sula, Banggai, Togian and other smaller nearby islands. It has often been considered conspecific with '' E. scolopaceus'', but they are increasingly treated as separate species. Unlike the black-billed koel, all other members of the common koel complex have a pale bill. The black billed koel voice a typical "koel!" call, or a short series of rising and falling "woo" notes.

Thick-billed Cuckoo
The thick-billed cuckoo (''Pachycoccyx audeberti'') is a species of cuckoo in the family Cuculidae. It is monotypic within the genus ''Pachycoccyx''. It can easily be distinguished from other brood parasitic cuckoo species by its very thick bill, which is shaped in a rather hawk-like fashion. Taxonomy In a molecular genetic study by Sorenson and Payne (2005), the thick-billed cuckoo appeared to be most closely related to the koels, consisting of the dwarf koel (''Microdynamis parva'') and the true koels (''Eudynamys''), although the evidence was not very strong and further research was required. Range and habitat The thick-billed cuckoo is found in humid to subhumid woodlands and gallery forests from Guinea in the northwest to Mozambique in the southeast, though it is absent from large areas of the Congo Basin.Paul Johnsgard, Johnsgard, Paul A.; ''The Avian Brood Parasites: Deception at the Nest''; pp. 159-161 It formerly occurred in the rainforests of northeastern Madagascar, b ...

Pacific Long-tailed Cuckoo
The Pacific long-tailed cuckoo (''Urodynamis taitensis''), also known as the long-tailed cuckoo, long-tailed koel, sparrow hawk, home owl, screecher, screamer or in Māori, is a species of the Cuculidae bird family (the cuckoos). It is a migratory bird that spends spring and summer in New Zealand, its only breeding place, and spends winter in the Pacific islands. It is a brood parasite, laying its eggs in the nests of other bird species and leaving them to raise its chicks. Taxonomy ''Urodynamis taitensis'' is most closely related to the channel-billed cuckoo (''Scythrops novaehollandiae''), which lives in Australia, Papua New Guinea and Indonesia, according to Sorenson and Payne (2005). Accordingly, it is not part of the ''Eudynamys'' genus (the true koels), with which it has previously been placed. Description The long-tailed cuckoo has a length of approximately 40–42 cm; wingspan of approximately 47–52 cm and weighs about 120 grams. Large cuckoo with broad po ...

Brood Parasite
Brood parasites are animals that rely on others to raise their young. The strategy appears among birds, insects and fish. The brood parasite manipulates a host, either of the same or of another species, to raise its young as if it were its own, usually using egg mimicry, with eggs that resemble the host's. The evolutionary strategy relieves the parasitic parents from the investment of rearing young. This benefit comes at the cost of provoking an evolutionary arms race between parasite and host as they coevolve: many hosts have developed strong defenses against brood parasitism, such as recognizing and ejecting parasitic eggs, or abandoning parasitized nests and starting over. It is less obvious why most hosts do care for parasite nestlings, given that for example cuckoo chicks differ markedly from host chicks in size and appearance. One explanation, the mafia hypothesis, proposes that parasitic adults retaliate by destroying host nests where rejection has occurred; th ...

White-crowned Cuckoo
The white-crowned cuckoo or white-crowned koel (''Cacomantis leucolophus'') is a species of cuckoo in the family Cuculidae. It was originally described by Salomon Müller as ''Cuculus leucolophus''. It was later placed in the monotypic genus ''Caliechthrus'', but most taxonomists place it the genus ''Cacomantis'' because it has a similar song to other cuckoos in this genus and it is genetically similar to the pallid cuckoo (''Cacomantis pallidus'').Payne, Robert B. (2005) ''The Cuckoos'', Oxford University Press. It is found in New Guinea and neighbouring Salawati Salawati is one of the four major islands in the Raja Ampat Islands in Southwest Papua (formerly West Papua), Indonesia. Its area is 1,623 km2.

Robert B
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be ...
