The taxonomic treatment [3] (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the accompanying bird lists adheres to the conventions of the AOS's (2019) Check-list of North American Birds, the recognized scientific authority on the taxonomy and nomenclature of North America birds.
These diving birds forage underwater. They prefer water depths of 1.2–4.5 m (3.9–14.8 ft). [8] In freshwater habitats, they eat primarily insects, and in saltwater, they feed predominantly on crustaceans and mollusks. Aquatic plants and fish eggs can often become locally important food items, as well.
It is found in the southern tip of the United States, most of Mexico, parts of Central America, the Caribbean islands and northwestern South America.

It is estimated that about 60% of the American bird population found North of the Mexican border nests in the boreal forest ...
The mountain habitat was consistent with that found on the breeding area. In March the population on the breeding area increased again, with most birds in groups of four to eight. [14] The average winter covey size for scaled quail is around 30 birds, although coveys of up to 150 birds have been reported. [17]
