Le motmot des Andes (Momotus aequatorialis) est un oiseau coloré, proche d'un passereau, que l'on trouve du nord de la Colombie à l'ouest de la Bolivie. Il est en général typique de sa famille : C'est un grand oiseau avec un bec noir et robuste et une longue queue avec un bout en forme de raquette. Il mesure de 46 à 48 cm de long et pèse de 143 à 202 g. Il réside dans les Andes, de la Colombie au département de La Paz, dans le nord-ouest de la Bolivie, en passant par l'Équateur et le Pérou. En Colombie, il est présent dans les trois principales cordillères, mais en Équateur, au Pérou et en Bolivie, on ne le trouve que sur le versant oriental des Andes. En Colombie, son altitude varie de 1 500 à 3 100 m, en Équateur de 1 000 à 2 100 m, au Pérou de 1 000 à 2 400 m et en Bolivie de 1 600 à 1 900 m.
Habitats et répartition
The Andean Motmot primarily inhabits subtropical and tropical montane forests, as well as forests' edges and secondary growth areas. It thrives at elevations ranging from 700 to 3,500 meters, favoring environments with dense understory vegetation that provides ample cover and feeding opportunities. These birds are often found near water sources, such as rivers and streams, which support a rich array of insect prey. Geographically, the Andean Motmot's range extends along the Andean mountain range from northern Colombia and Venezuela through Ecuador and into northern Peru. This distribution covers a breadth of diverse ecological zones, allowing the species to adapt to various microhabitats within these montane regions. They are particularly common in cloud forests, which offer the humidity and dense foliage essential for their foraging and nesting behaviors.
Comportements et reproduction
The Andean Motmot exhibits intriguing reproductive behavior that aligns with their monogamous mating system. During the breeding season, which typically occurs from March to July, pairs engage in elaborate courtship displays involving synchronized wing beats and tail flicks to strengthen pair bonds. They often nest in burrows that the pair excavates in earthen banks or soft ground, showing a strong partnership as they share the responsibility of incubating eggs and feeding the chicks. These burrows can be surprisingly deep, sometimes reaching up to 2 meters in length. In terms of social structure, the Andean Motmot is generally seen alone or in pairs, emphasizing their focus on pair bonding over group dynamics. They are territorial during the breeding season, actively defending their nesting sites from intruders. Uniquely, they have a delayed reproductive strategy, with young birds often staying close to their parents' territory for an extended period, possibly assisting with future broods or learning vital survival skills before establishing their own territories. This approach likely enhances the survival rates of their offspring in the diverse and sometimes harsh environments of the Andes.

Il est connu pour son cri unique et sa capacité à rester immobile pendant de longues périodes.
Statut de conservation et efforts
The Andean Motmot (Momotus aequatorialis) is currently classified as Least Concern by the IUCN, indicating it is not immediately at risk. The species has a relatively stable population trend, although local declines have been noted due to habitat loss. Primary threats include deforestation for agriculture, urban expansion, and infrastructure development, which reduce the availability of suitable nesting and feeding sites. Conservation efforts for the Andean Motmot focus on habitat protection and restoration. This includes the establishment and management of protected areas within the Andean regions where the bird resides. Additionally, local and international organizations are engaged in reforestation programs and promoting sustainable agricultural practices to mitigate habitat destruction. Public awareness campaigns and ecotourism initiatives are also instrumental in fostering community support for conserving this vibrant species and its habitat.
