Wood Stork

Identification

The wood stork is a large wading bird standing 83 to 115 cm (33–45 in) tall with a wingspan of 140 to 180 cm (55–71 in). Males typically weigh 2.5 to 3.3 kg (5.5–7.3 lb), while females are slightly lighter at 2.0 to 2.8 kg (4.4–6.2 lb). The most distinctive feature is its bare head and neck covered in dark grey, scaly skin. The long, downward-curved bill is black and notably wide at the base. Plumage is predominantly white, with black primaries, secondaries, and tail feathers that display an iridescent greenish and purplish sheen. Legs and feet are dark, with pink or beige-coloured toes that become brighter pink during breeding season. The sexes are similar in appearance. Fledged juveniles resemble adults but retain a feathered head and yellow bill.

Range & Habitat

The wood stork is native to the subtropics and tropics of the Americas, making it the only stork species that breeds in North America. Its range extends from the southeastern United States through Mexico, Central America, Cuba, and into South America as far south as northern Argentina. Within the United States, small breeding populations occur in Florida, Georgia, and the Carolinas, with post-breeding birds reaching as far west as Alabama and Mississippi. In Mexico, breeding colonies are restricted to the Pacific coast, particularly in Oaxaca and Colima. Cuba hosts the only known Caribbean breeding locations in the Zapata Swamp and Sabana-Camaguey Archipelago. South American populations concentrate in the Pantanal wetland and northern coastal regions of Brazil, with some birds dispersing south to Argentina after breeding.

The wood stork thrives in tropical and subtropical wetland habitats with fluctuating water levels, which trigger breeding activity. It nests in trees situated over water or surrounded by water, preferring Taxodium forests in freshwater habitats and mangrove forests in estuaries. For feeding, the species uses freshwater marshes, brackish waters, and lake, stream, and river edges depending on local vegetation and water conditions.

Behaviour & Diet

Wood storks are colonial breeders that build large, one-metre-diameter nests in trees, with up to 25 nests occasionally occupying a single tree. In freshwater habitats, they prefer larger-diameter trees and typically nest near the top branches of Taxodium trees, 18 to 24 metres above ground. In mangrove forests, nests are positioned at more variable heights between 2.5 and 6.5 metres, selected at forks of large limbs or where multiple branches cross. The specific feeding behaviour and diet of the wood stork are not detailed in available sources, but as a wading bird, it hunts in shallow wetland waters typical of its habitat.

Best Time & Places to See It

The wood stork is a resident breeder in lowland wetlands across its range, making it potentially visible year-round in suitable habitats. The Florida Everglades and other southeastern United States wetlands offer reliable viewing opportunities, though the species was historically concentrated in Florida. The Pantanal wetland in Brazil and the coastal regions of Mexico provide excellent opportunities for observing this species in its tropical range. Colonial nesting sites in spring and early summer offer the best chances to observe multiple individuals and breeding behaviour.

Photography Tips

The wood stork's distinctive bare head, neck, and striking black-and-white plumage make it visually striking to photograph. Its large size and colonial nesting behaviour provide opportunities for both individual portraits and group compositions. Photograph nesting colonies from a respectful distance to avoid disturbing breeding birds. The bird's dark plumage contrasts sharply with wetland backgrounds, so position yourself with water or vegetation behind the subject for optimal separation. Telephoto lenses are essential for capturing detail of the bare head and bill without approaching nesting sites. Early morning and late afternoon light will enhance the subtle greenish-purplish iridescence visible on the black wing and tail feathers.
