A Calhandra (Sipia palliata) é uma ave de tamanho médio, de cauda curta e com um olho vermelho vivo. A cabeça e o peito são cinzentos-ardósia, a garganta é preta, o ventre e as partes superiores são castanhos e as asas são pontilhadas de branco. A fêmea é semelhante, mas tem a garganta barrada de branco e as asas com pintas esbranquiçadas. Não há sobreposição com os pássaros semelhantes de cabeça chata ou de Esmeraldas. Frequentemente encontrados em pares, tipicamente em ravinas rochosas sombreadas ao longo de riachos no sopé das montanhas. Muitas vezes bastante vocal; o canto é uma série de notas fortes e relativamente agudas "fee-feet-feet-FEET-feteu-feek!", e o chamamento é um "FEeuh" áspero.
Habitats e distribuição
The Magdalena Antbird inhabits subtropical or tropical moist lowland forests, favoring dense undergrowth and forest edges where it can forage among leaf litter and tangled vegetation. It thrives in areas with plenty of cover, often near water sources such as rivers and streams, which provide both food and shelter. Geographically, this bird is found primarily in Colombia, specifically within the Magdalena River Valley. Its range extends to nearby regions, predominantly in the northern and central parts of the country. The species relies on the continuity of its habitat, making deforestation and habitat degradation significant threats to its population stability.
Comportamentos e reprodução
The Magdalena Antbird exhibits a monogamous mating system, with pairs forming stable, long-term bonds. The pair cooperatively defends their territory against intruders and participates in joint parenting duties. Nesting typically occurs in dense underbrush or low vegetation, where the female lays a clutch of two to three eggs. Both parents share the responsibilities of incubation and feeding the chicks until they fledge, which ensures a high survival rate for their offspring. Socially, Magdalena Antbirds are known for their strong pair bonds and territoriality. They communicate through a complex system of vocalizations to maintain their territory and coordinate parenting activities. Unique to their reproductive strategy is the use of duets—a series of coordinated calls between the male and female—which not only strengthens their pair bond but also serves as a deterrent to potential rivals and predators, thus enhancing the protection of their offspring.

Estado de conservação e esforços
The conservation status of the Magdalena Antbird (Sipia palliata) is classified as Near Threatened by the IUCN. The species is experiencing a decline in population primarily due to habitat loss and degradation, driven by deforestation for agricultural expansion, logging, and infrastructure development. Fragmentation of its habitat in the tropical forests of Colombia poses a significant threat to its survival, as it limits the bird's natural range and affects its ability to thrive. Conservation efforts for the Magdalena Antbird focus on habitat protection and management. Various protected areas have been established within its range to safeguard crucial habitats, such as the creation of national parks and nature reserves. Additionally, there are initiatives to promote sustainable agricultural practices and reforest degraded areas to restore and expand suitable habitats. Conservation organizations are also working to raise awareness among local communities about the importance of maintaining the bird's habitat and biodiversity, thereby fostering community-led conservation actions.
