Distribution

The distribution of the Chestnut-collared Swallow is southwestern Ecuador and northwestern Peru. In Ecuador, this species occurs in Manabí (north to the area of the Bahía de Caráquez), Guayas, El Oro, and in western Loja (Ridgely and Greenfield 2001a). and western Peru (south to Lima). In Peru, the Chestnut-collared Swallow occurs along the coast of northern and central Peru, from the northern department of Piura south to the southern department of Lima (Schulenberg et al. 2007), in the Cañete river valley (T. Schulenberg and T. A. Parker, sight records).

The elevational distribution of the Chestnut-collared Swallow in Ecuador is from sea level up "to about 2000 m" (Best and Clarke 1991, Bloch et al. 1991, Ridgely and Greenfield 2001b); in Peru, the elevational range is narrower, where it is reported above 1000 m (Schulenberg et al. 2007).

Endemic to the Americas.

The description of the habitat by Nation (1885) remains valid today: "“cultivated lands in the river-districts of the narrow strips of arid country situated between the Pacific and the mouths of the Andean valleys;” see also Ridgely and Greenfield 2001b, Schulenberg et al. 2007.

The distribution in Ecuador appears to be expanding; for example, it now breeds "in substantial numbers" on the Santa Elena peninsula in western Guayas province, although apparently it did not occur at all there in the 1950s (Ridgely and Greenfield 2001a).
