El chochín de Munchique (Henicorhina negreti) es un pequeño chochín de cola rechoncha endémico de los Andes occidentales de Colombia. Tiene una ceja larga y blanca y la cara estriada. Es muy similar al chochín pechigrís, pero tiene un barrado muy tenue en el vientre. Esto es muy difícil de ver en el campo, y por lo general la voz es la mejor manera de separarlos. El canto del chochín de Munchique es ligeramente más bajo y las notas son más planas y menos chirriantes. Habita en el sotobosque del bosque nuboso, generalmente en elevaciones más altas que el pechigrís, pero con cierto solapamiento.
Hábitats y distribución
The Munchique Wood-Wren inhabits montane cloud forests of the Western Andes in Colombia. These forests are characterized by high humidity, dense vegetation, and a canopy that is typically shrouded in mist. The species thrives at elevations ranging from 2,200 to 3,100 meters above sea level, where it prefers the thick understory of mature forests with ample mosses, ferns, and other epiphytes. Geographically, the distribution of the Munchique Wood-Wren is extremely limited, confined to the Munchique National Natural Park and its immediate surroundings. This narrow range makes the bird particularly vulnerable to habitat loss due to deforestation and other human activities. The restricted range combined with specific habitat requirements highlights the importance of conservation efforts within these montane cloud forests.
Comportamiento y reproducción
The Munchique Wood-Wren exhibits monogamous mating behavior, typically forming long-term pair bonds. During the breeding season, males sing complex, melodious songs to attract females and defend their territory from rivals. Both parents are involved in nest building, which usually consists of a dome-shaped structure constructed from moss and leaves, situated low in dense vegetation for camouflage. Their social structure largely revolves around the breeding pair and their offspring, with little evidence of cooperative breeding or large family groups. Unique reproductive strategies include synchronous hatching, where eggs hatch around the same time to ensure equal feeding opportunities for all chicks, enhancing survival rates. These strategies reflect the species' adaptation to their montane forest habitat, where resources can be scattered and conditions harsh.

Estado y esfuerzos de conservación
The Munchique Wood-Wren is currently listed as endangered, with its population estimated to contain fewer than 2,500 mature individuals. The population is believed to be in decline primarily due to habitat destruction and degradation. Key threats include deforestation for agricultural expansion, logging, and human settlement, all of which reduce the montane cloud forests that this species relies on. Conservation efforts for the Munchique Wood-Wren focus on habitat protection and restoration. Significant measures include the establishment and management of protected areas, such as the creation of the Munchique National Park, which aims to preserve intact forest ecosystems. Additionally, conservation initiatives involve working with local communities to promote sustainable land use practices that minimize forest loss, alongside research and monitoring programs to better understand the species' ecology and population dynamics. These efforts are crucial to prevent further decline and to promote the recovery of this elusive bird.
