Justification of Red List category
This species is classified as Near Threatened because its small population is suspected to be declining slowly owing to habitat loss.

Population justification
The species is described as 'rare' (Stotz et al. 1996). Based on the population density of Bucco macrodactylus (2 individuals/km²) and an area of suitable habitat of c. 6,000 km², the population is inferred to number c.12,000 individuals (Renjifo et al. 2014), which roughly equates to 8,000 mature individuals.

The subpopulation structure has not been formally assessed. Based on the spatial spread of observational records within the range (eBird 2021) and the species's resident nature (Rasmussen et al. 2020), it is conceivable that the species forms at least ten subpopulations. It is tentatively suspected that no subpopulation numbers more than 1,000 mature individuals.

Trend justification
The population is suspected to be in decline owing to ongoing habitat destruction. Forest within the range has been lost at a rate of <5% over three generations (Renjifo et al. 2014; Global Forest Watch 2021) and habitat is largely degraded (P. Salaman in litt. 2020). Population declines are here tentatively placed in the band 1-9% over three generations (10.8 years).

This species has a moderate-sized range in west Colombia, from the west side of the Gulf of Urabá, south through Chocó, and from west Antioquia to the río San Juan delta. The species is common in Los Katíos National Park, Chocó (P. G. W. Salaman in litt. 1998, 1999, F. G. Stiles in litt. 1999).

The species inhabits humid forest, secondary growth and occasionally adjacent non-forest areas in flat lowland areas below 100 m (Hilty and Brown 1986; F. G. Stiles in litt. 1999). It is an inconspicuous species, perching motionless on open branches for long periods before stooping on large insects in the understory foliage (P. G. W. Salaman in litt. 1998, 1999).

Logging and conversion to banana and oil palm plantations are causing considerable rates of deforestation, with human settlement, infrastructure development, cattle ranching and other agricultural land use also significant threats (Dinerstein et al. 1995, Wege and Long 1995, P. G. W. Salaman in litt. 1998, 1999).

Conservation Actions Underway
The species is common in Los Katíos National Park, Chocó (P. G. W. Salaman in litt. 1998, 1999, F. G. Stiles in litt. 1999). It is further present in Ensenada de Utría.

Conservation Actions Proposed
Conduct surveys to assess its status (Hilty and Brown 1986). Effectively protect national parks where the species occurs.
