Brown Diving Beetle

The Brown Diving Beetle (Agabus brunneus) is a species in the genus Agabus. It is currently classified as Extinct on the IUCN Red List. Typically found in virtually all terrestrial and freshwater habitats.

Collared Antshrike

<em>Thamnophilus bernardi</em>, the Collared Antshrike, is a passerine bird in the family Thamnophilidae, a group of antbirds found in the Neotropics. This species is assessed as Least Concern on the IUCN Red List. It is documented in Ecuador, where it inhabits scrub, thickets, and dry woodlands in the western lowlands and foothills. Members of the genus <em>Thamnophilus</em> are typically sexually dimorphic, with males often displaying strongly patterned plumage and females more cryptically colored. Antbirds in this family are known to glean insects and other arthropods from vegetation. The Collared Antshrike occupies aerial, terrestrial, and associated environmental zones within its range. Diet information, population estimates, and biological measurements such as average length, weight, and lifespan are not specified in available records. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern status indicates that populations are currently stable, though continued pressure on dry forest habitats in western Ecuador may warrant monitoring.
