Comportamento

The purple quail-dove forages on the ground, singly or in pairs. Its diet has not been documented but it probably eats seeds and small invertebrates like other quail-doves.<p>A male purple quail-dove with enlarged testes was taken in Ecuador in June, but no other information about its breeding phenology is known.<p>The purple quail-dove's song is "a sustained series of soft, hollow coos, 'whot, WHOO-OO-OIT'."
