Comparison of the Oxygen Diffusing Capacity of the Picui Ground Dove (Columbina picui) with Other Doves of Chile
We studied the respiratory surface density and the thickness of the air-blood barrier in the Picui Ground Dove (Columbina picui), and compared it with Eared Dove (Zenaida auriculata) and Blacked-winged Ground Dove (Metropelia melanoptera), two larger species. As expected, Columbina picui BMR and VO2...
