The White Winged Dove has a special partnership with the saguaro cactus. The birds time their migration to the Sonoran Desert to coincide with the blooming of the Saguaro Cacti. The doves rely on saguaros for water and nutrients during breeding season.
On the other hand the cacti rely on the doves for pollination as they go from flower to flower sipping nectar. When the flowers turn to fruit, about the end of June, they are filled with thousands of small saguaro cactus seeds which the doves help to spread as they regurgitate food to their young and spread the seeds through their droppings.
