Appearance
"Tolmomyias" flatbills are robust small birds with broad beaks. The grey-crowned flatbill is about 12 cm long and has a generally yellowish-green plumage, a grey cap and nape, and a yellowish throat marked with grey. The iris is usually a pale colour and the mandible has a dark tip. Several species of flatbill overlap in their range and are easily confused with each other visually, but their songs are mostly distinctive.
Distribution
The grey-crowned flatbill is native to the Amazon region of South America. Its range includes Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname and Venezuela. Its maximum altitudinal range extends to 1,000 m or locally higher. It generally inhabits the middle and upper canopy of the rainforest as well as forest edges, river valleys and tall secondary forest growth. The nest is shaped like a bag and has a tubular entrance near the base; it is often hung near a wasp nest.Status
The grey-crowned flatbill has a very wide range in the Amazon rainforest and on the lower slopes on the eastern side of the Andes. It is said to be a fairly common species and its population trend may be declining slightly but not at a rate that would cause concern, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".References:
