Implication

Randomized trial investigates the influence of elevation and land cover on migratory bird abundance in the Andes, suggesting key habitat types for conservation.

Key Points

This research examines how elevation and land cover affect migratory bird abundance in the Colombian Andes.
Conducted 1,606 distance-sampling point counts in the Colombian Andes at elevations from 253 to 3,708 m.
Utilized multispecies hierarchical modeling to analyze effects of elevation, land cover, and precipitation on bird abundance.
Considered observer and time of day effects on detectability during analysis.
Elevations and land cover strongly influenced migratory bird abundance, with a peak observed at mid-elevations.
Highest mean abundance found in shade coffee plantations, secondary forests, and mature forests.
No significant community-level response to precipitation, with only a weak tendency for birds selecting intermediate precipitation areas.
