領蚋鷯

<em>Microbates collaris</em>, the Collared Gnatwren, is a small insectivorous bird in the family Polioptilidae. This species is assessed as Least Concern on the IUCN Red List. It is documented in Colombia, Ecuador, and Venezuela, inhabiting the understory of humid tropical forests in lowland and foothill areas. The genus <em>Microbates</em> comprises the gnatwrens, small, wren-like birds that creep through dense undergrowth searching for insects and other arthropods. The Collared Gnatwren is named for the dark collar visible on its throat and breast, which contrasts with its white underparts. It tends to remain low in the forest understory and can be difficult to observe despite being heard more readily. Diet, population estimates, population trend, and biological measurements including average length, weight, and lifespan are not specified in the available records. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern status indicates that populations are currently stable within its northern South American range.
