The Turquoise Jay occurs in the Andes from southern Colombia south to northwestern Peru. In Colombia it is known from both slopes of the Andes of Nariño, and possibly occurs north to Parque Nacional Puracé in Cauca (Hilty and Brown 1986). It also occurs on both slopes of the Andes in Ecuador, where there are a few remnant populations found on the slopes above the central valley (Ridgely and Greenfield 2001a). In Peru it is found on both slopes of the western Andes in Piura and Cajamarca, north and west of the Río Marañón.
The elevational range of the Turquoise Jay in Colombia is at least 2600-3000 m (but "prob[ably] lower and higher"; Hilty and Brown 1986); in Ecuador it is "most numerous from 2000 to 3000 m" but occasionally occurs up to 35oo m (Ridgely and Greenfield 2001a); and in Peru it has been reported at 2400-3000 m (Schulenberg et al. 2007). Fjeldså and Krabbe (1990) give the elevational distribution, across the entire range of the species, as 1850-3200 m.
