A carriça-de-peito-branco (Henicorhina leucosticta) é uma carriça muito pequena, de cauda atarracada, das florestas tropicais húmidas de planície. Prefere o sub-bosque da floresta, onde normalmente se encontra perto ou no chão. Ouve-se muito mais frequentemente do que se vê, e é notavelmente esquiva, mesmo em sub-bosques bastante abertos. O chamamento comum é um "peenk" metálico, parecido com o de uma rã e difícil de localizar. Os vários cantos assobiados são bastante curtos, geralmente introduzidos com um silvo silencioso. De notar a face fortemente listada, o babete branco, as partes superiores castanhas escuras e a cauda curta. A carriça de peito cinzento ocorre nas terras altas.
Habitats e distribuição
The White-breasted Wood-Wren inhabits tropical and subtropical forests, favoring dense undergrowth in both primary and secondary forests. It thrives in moist environments, often near streams and rivers, and can be found at elevations ranging from sea level up to 1,500 meters. This bird is highly adaptable, also occupying forest edges, overgrown plantations, and gardens. Geographically, the White-breasted Wood-Wren's range extends from southern Mexico through Central America, including Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, and Panama, down into northern South America in Colombia, Venezuela, Ecuador, Peru, and Bolivia. Its presence in varied regions emphasizes its adaptability to different tropical and subtropical environments.
Comportamentos e reprodução
White-breasted Wood-Wrens exhibit a monogamous mating system, with pairs forming long-term bonds that often last for multiple breeding seasons. These birds are highly territorial and invest considerable effort in defending their space from intruders. Their courtship involves intricate duets, where male and female partners sing in a synchronized manner, strengthening their bond and warding off rivals. They typically construct their nests close to the ground, hidden in dense vegetation, which provides concealment from predators. The reproductive strategy of White-breasted Wood-Wrens includes laying 2 to 3 eggs per clutch, with both parents sharing the responsibilities of incubation and feeding the nestlings. They can be fiercely protective of their offspring and will engage in deceptive behaviors, such as feigning injury, to draw potential threats away from the nest. The social structure is primarily based around the mated pair and their current brood, with limited interaction outside the immediate family unit, ensuring focused care and protection for their young.

Estado de conservação e esforços
The conservation status of the White-breasted Wood-Wren (Henicorhina leucosticta) is currently listed as Least Concern by the IUCN. Its population is considered stable, with no immediate widespread threats that would cause significant declines. However, localized threats such as deforestation and habitat fragmentation pose risks to its preferred tropical and subtropical humid forest habitats. The bird is relatively resilient owing to its wide distribution in Central and South America. Conservation efforts focus primarily on habitat preservation and restoration. Protected areas and national parks in countries including Mexico, Costa Rica, and Colombia help safeguard critical habitats for this species. Additionally, reforestation projects and sustainable land-use practices aim to mitigate the impact of habitat loss. Community awareness programs also play a role in promoting the importance of forest conservation for maintaining healthy populations of birds like the White-breasted Wood-Wren.
