Flamingo males are both loving husbands and attentive fathers. They congregate in flocks that can number in the hundreds of thousands, but flamingos generally remain monogamous for life. A male dutifully follow his spouse's lead in selecting a nesting site and then aids in the construction of the mud nest. Both take turns incubating their single egg and defending the nest, and both share duties in rearing the hatchling.
