Macareux à gorge rousse

Hypnelus ruficollis

Oiseau trapu, au bec robuste et souvent très voyant, que l'on trouve principalement dans les forêts sèches et semi-humides au nord et à l'ouest des Andes. Notez le dessin orné de la face, la gorge chamoisée et la bande noire unique sur la poitrine. Les couples se perchent souvent à découvert sur des branches exposées, des fils ou des clôtures, d'où ils s'élancent pour attraper une grande variété de proies. Le chant est une longue série de sifflements ou de gloussements. Le mâle et la femelle chantent souvent ensemble dans un duo bruyant et chaotique.

Habitats et répartition

The Russet-throated Puffbird inhabits a variety of lowland environments, primarily favoring dry forests, open woodlands, and scrubby areas. It can also be found in more humid forest edges and secondary growth, often near streams or other water sources. This preference for diverse habitats allows the puffbird to exploit a range of ecological niches, from dense canopy cover to more open, sunlit areas. Geographically, this species is distributed across northern South America, particularly in northern Colombia and northwestern Venezuela. In these regions, it is relatively common and can adapt to a variety of environmental conditions, contributing to its widespread presence. The bird is particularly well-suited to tropical and subtropical climates within its range, where it finds ample food sources and suitable nesting sites.

Comportements et reproduction

The Russet-throated Puffbird exhibits a relatively modest and unassuming social structure, often seen in pairs or small family groups. These monogamous birds engage in cooperative breeding, where offspring from previous broods may assist in caring for the next set of chicks. During courtship, males perform a series of calls and displays to attract females, often involving puffing their throats and showcasing their vibrant russet coloring. Reproduction typically takes place in cavities excavated in termitaries, trees, or earthen banks. Both parents share the responsibilities of incubating the eggs, which generally number between two to three per clutch, and feeding the chicks once they hatch. The altricial young are cared for intensively until they fledge, after which they may continue to rely on parental support for an extended period. This cooperative behavior enhances the survival rate of the offspring in their native habitats.

Régime alimentaire

Il se nourrit principalement d'insectes, mais aussi de petits vertébrés comme les lézards et de quelques fruits.

Couleurs

La face est principalement blanche avec un grand œil jaune. Les parties supérieures sont brunes avec des taches blanchâtres et l'extrémité des ailes blanches.

Faits amusants

Semblable à l'oiseau à deux bandes, que l'on trouve surtout à l'est des Andes, mais qui n'a jamais plus d'une bande.

Statut de conservation et efforts

The Russet-throated Puffbird (Hypnelus ruficollis) is currently classified as Least Concern by the IUCN. Its population is considered stable, and the species is relatively widespread within its range, which includes regions in Colombia and Venezuela. Although specific population numbers are not well-documented, there is no evidence of a rapid decline that would warrant a more threatened status. Primary threats to the Russet-throated Puffbird include habitat loss due to deforestation and agricultural expansion. Despite these pressures, the bird's adaptability to degraded habitats has somewhat mitigated the impact. Conservation efforts focus on habitat protection and environmental education to curb deforestation rates. Additionally, several protected areas within the bird's range offer some degree of habitat security, promoting long-term population stability.
