Description
Tolmomyias flatbills are robust small birds with broad beaks. The grey-crowned flatbill is about 12 cm (4.7 in) 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. The grey-crowned flatbill's song is a series of whistles rising in pitch with the final whistle trembling – "tuee? tuee? TUEE? tuEEuEE? tuEEuEE?". The only other similar song in the genus is that of the yellow-margined flatbill (Tolmomyias assimilis) which has a more rasping quality; flatbills in this genus are difficult to tell apart and the voice is usually the best means of recognition. The stance of this species is more horizontal than other members of the genus, and it sometimes cocks its tail.

Feeding Habits
Grey-crowned Flatbill primarily consumes bugs and beetles, particularly Hemiptera and Curculionidae. They forage alone or in pairs within mixed-species flocks, adopting a unique high-level perching and tail-cocking behavior, and utilize upward-strike and hover-gleaning techniques for insect capture.
Habitat
Grey-crowned Flatbill typically inhabits tropical regions, favoring humid environments such as the middle and upper canopy levels of terra firme and várzea rainforests. This species also thrives at forest edges, river valleys, and in areas with tall secondary growth. Beyond the dense forest, grey-crowned Flatbill can be found in wooded sand ridges, coffee plantations, and garden landscapes within the savanna. Generally residing at elevations below 600 meters, grey-crowned Flatbill is also known to occupy regions up to 1000 meters above sea level.

General Info
Distribution Area
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 (3,300 ft) 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.
Species 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".
