Great woodswallow
The great woodswallow (''Artamus maximus''), also known as the greater woodswallow, giant woodswallow or New Guinea woodswallow is a species of bird in the Artamidae family. As its name implies, it is the largest member of the genus ''Artamus'', averaging in length and in mass.〔McNab, Brian K.; “Ecological Energetics of Birds in New Guinea”; in ''Bulletin of Florida Museum of Natural History'', vol. 52(2); pp. 96-159〕 In appearance the great woodswallow is very similar to the more widespread white-breasted woodswallow but can be distinguished by its darker black upper side plumage and by the presence of a semi-oval black patch below the throat.〔Coates, Brian J.; ''The Birds of Papua New Guinea Including the Bismarck Archipelago and Bougainville: Volume 2 - Passerines''; pp. 373-375. ISBN 0959025715〕
==Distribution and habitat==
The great woodswallow occurs naturally in tropical moist montane forest, usually amongst clearings with dead trees, most typically dead emergents above the canopy of primary rainforest. Although the species has been known to be common ever since the first Western explorers of New Guinea,〔Sclater, P.L.; “On Recent Ornithological Progress in New Guinea”; in ''Ibis'' Volume 18, Issue 2 (April 1876), pp. 243–259〕 it has adapted very well to human manipulation of the landscape and is especially common near Highland towns such as Mount Hagen and Goroka.〔 Great woodswallows are found as high as , but are most abundant between and . Unlike the Australian dusky woodswallow,〔Maddocks, Tracy A. and Geiser, Fritz; “Heterothermy in an Australian passerine, the Dusky Woodswallow (''Artamus cyanopterus'')”; in ''Journal of Ornithology'', Volume 148, Issue 4(October 2007); pp. 571-577〕 great woodswallows do not reduce their body temperature on cool nights.〔
