Le pic brun (Picumnus granadensis) est propre à la Colombie et se reconnaît à son aspect tacheté. C'est une petite espèce de pic que l'on trouve dans les forêts. Il a un plumage brun grisâtre avec des motifs complexes, un bec court et une queue raide. Il se nourrit sur les troncs d'arbres, à la recherche d'insectes et de larves. Pic minuscule ressemblant un peu à une sittelle. Son bec est court et ciselé et sa queue est courte. Dessus gris-brun uni et dessous légèrement plus pâle, sans stries ; noter la couronne foncée avec de petites taches blanches. On le trouve dans une grande variété d'habitats forestiers, même autour des lisières et des repousses. Se faufile autour des petites branches et des lianes, souvent suspendu à l'envers. Les sexes sont semblables ; les mâles ont une tache jaune sur la couronne (pas seulement blanche).
Habitats et répartition
The Grayish Piculet inhabits subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is also found in heavily degraded former forests, indicating some adaptability to human-altered landscapes. These environments provide the dense vegetation and plentiful insect life that the species relies on for feeding and nesting. Geographically, the Grayish Piculet is primarily found in the northern Andes of Colombia and Venezuela. Its range extends across the slopes of these mountains, where it occupies both primary and secondary growth forests. This bird is typically seen at altitudes ranging from 500 to 2,500 meters, with a preference for lower elevation forests.
Comportements et reproduction
Grayish Piculets engage in monogamous mating habits, where pairs form stable bonds that often last for multiple breeding seasons. They generally build their nests in tree cavities, which they excavate themselves, usually choosing soft or decayed wood for ease of drilling. Nesting duties are shared between both partners, from the excavation process to incubation and feeding of the young. Socially, these birds are relatively shy and tend to be seen either alone or in pairs, seldom forming large flocks. During the breeding season, they become particularly territorial and may engage in vocal displays to ward off rivals. Their reproductive strategy involves laying a small clutch of eggs, typically two to four, ensuring that both parents can provide adequate care and food for the fledglings, enhancing the offspring's survival rate.

Statut de conservation et efforts
The Grayish Piculet (Picumnus granadensis), listed as Near Threatened on the IUCN Red List, has seen its population trend decline mainly due to habitat loss. This bird, endemic to the subtropical forests of Colombia, faces significant threats from deforestation driven by agricultural expansion, logging, and human settlement. These activities result in the fragmentation of its habitat, reducing viable living and breeding spaces. Conservation efforts for the Grayish Piculet include habitat preservation and restoration initiatives. Protected areas have been established to safeguard critical habitats, and reforestation projects aim to reconnect fragmented forests. Organizations are also working with local communities to promote sustainable land use practices, thereby reducing the pressure on the species' natural habitats. Environmental education campaigns are underway to raise awareness about the bird's plight, encouraging community-driven conservation actions.
