Greater Scythebill

The greater scythebill (Drymotoxeres pucheranii) is a species of suboscine passerine bird in the subfamily Dendrocolaptinae of the ovenbird family Furnariidae. It is found in Colombia, Ecuador, and Peru. == Taxonomy and systematics == The greater scythebill was long included in genus Campylorhamphus with most other scythebills, but the discovery of its closer affinities with the scimitar-billed woodcreeper (Drymornis bridgesii) resulted in the creation of the new genus Drymotoxeres for the greater scythebill. The two are genetically more closely related to each other than to the other scythebills and woodcreepers. The greater scythebill is the only member of its genus and is monotypic: no subspecies are recognized. == Description == The greater scythebill is 24 to 30 cm (9.4 to 12 in) long and weighs 63 to 78 g (2.2 to 2.8 oz). It is the largest and heaviest scythebill with a shorter, stouter, and less curved bill than the others. The sexes have the same plumage.
