Yellow-margined Flatbill
The yellow-margined flatbill or Zimmer's flatbill (''Tolmomyias assimilis'') is a species of bird in the tyrant flycatcher family Tyrannidae. It is found in every mainland South American country except Argentina, Chile, Paraguay, and Uruguay. Taxonomy and systematics The yellow-margined flatbill has a complicated taxonomic history. It was originally described as ''Rhynchocyclus assimilis''. In the early twentieth century it was treated as a subspecies of the yellow-olive flatbill (now ''T. sulphurescens'') but was separated by most authors starting in about 1940. As of 2025 it has eight subspecies. However, what is now the yellow-winged flatbill (''T. flavotectus'') was previously a ninth subspecies. It was separated starting in 2016 but the process continued until 2024. Confusingly, for a time ''T. flavotectus'' was called the yellow-margined flatbill.Remsen, J. V., Jr., J. I. Areta, E.

Remiges
Flight feathers (''Pennae volatus'') are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (), singular remex (), while those on the tail are called rectrices ( or ), singular rectrix (). The primary function of the flight feathers is to aid in the generation of both thrust and lift, thereby enabling flight. The flight feathers of some birds perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extra-stiff rectrices of woodpeckers help them to brace against tree trunks as they hammer on them. Even flightless birds still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
