Reproduction
A. anhinga is believed to reach sexual maturity around two years of age. Breeding occurs seasonally in North America. In sub-tropical or tropical latitudes, breeding can occur throughout the year, or be triggered by wet or dry seasons. A. anhinga is monogamous and pairs may reuse nests from year to year. The male begins courtship by soaring and gliding, followed by marking a possible nest location with leafy twigs. Then it performs behavioral displays to attract the female. Once the pair is formed, the male gathers nesting material, while the female builds a platform nest, which is usually on a branch overhanging water or in open areas in the tops of trees. The female constructs the nest by weaving sticks together and padding it with live twigs and green leaves.

The pair copulate on the nest, the male holding onto a stick or the female's bill with his bill. The female lays one egg every one to three days, until she has a clutch anywhere from two to six eggs. Average clutch size is four eggs. The oval-shaped eggs are bluish-white or pale green, sometimes occurring with brown speckles. The parents share in incubating the eggs for 25 to 30 days.
