White-winged Doves and Saguaro Cactuses

White-winged Doves are common throughout Central America, the Caribbean, and North America’s Desert Southwest. Like the closely related Mourning Doves, they primarily eat seeds and grains. But in the Sonoran Desert, White-winged Doves time their migration to sync up with the Saguaros’ reproductive cycle – to the benefit of both species. The cacti provide doves with a crucial source of water in the driest part of the Sonoran summer. The doves sustain the saguaros as pollinators and seed dispersers. It’s a classic case of mutualistic symbiosis.
