Ave aquática enorme, de pernas compridas, preta e branca, mais ou menos do tamanho da garça-real. O bico é mais grosso e mais curvo do que o das garças. Alimenta-se principalmente de peixes, movendo o bico aberto através da água até sentir a presa. Encontra-se em zonas húmidas, particularmente em pântanos inundados e lagoas pouco profundas.
Habitats e distribuição
The Wood Stork primarily inhabits wetlands, including freshwater and brackish wetlands such as swamps, marshes, and mangroves. It favors environments with shallow water where it can easily forage for fish, amphibians, and other aquatic prey. These birds are often found nesting in large trees or shrubs that are situated near water bodies, providing a strategic advantage for both feeding and protection from predators. Geographically, the Wood Stork's range extends across the southeastern United States, primarily in Florida, Georgia, and South Carolina, as well as in tropical and subtropical regions of Central and South America. In the U.S., their presence is more prominent during the breeding season, while some populations migrate to South America for the winter. Key countries in its non-U.S. range include Mexico, Cuba, Argentina, and Brazil, where they inhabit similar wetland and swamp areas.
Comportamentos e reprodução
Wood Storks exhibit social nesting behavior, often forming large breeding colonies in trees or shrubs near water bodies. These birds engage in monogamous relationships during the breeding season, with pairs cooperating in nest-building and chick rearing. Courtship includes mutual preening and bill-clattering displays, which strengthen pair bonds. Females typically lay 2 to 5 eggs, and both parents participate in incubation, which lasts around 30 days. Post-hatching, the parents take turns feeding the chicks regurgitated food until they fledge at approximately 8 weeks old. The species employs a unique reproductive strategy related to the timing of nesting; they usually begin to breed in the dry season when falling water levels concentrate fish in dwindling pools, making it easier to feed their young. This adaptive strategy ensures a higher rate of chick survival, as food resources become more accessible. Their social structure not only aids in protection against predators but also enhances the efficiency of locating food sources through communal foraging.
Dieta
Peixes, anfíbios, répteis, pequenos mamíferos
Cores
Corpo branco com penas de voo pretas. Os adultos têm a cabeça careca e enrugada e o bico bastante escuro; os juvenis têm o bico mais pálido e as penas da cabeça e do pescoço mais desordenadas.
Factos divertidos
Voa frequentemente, por vezes com os abutres. Na América Central e do Sul, comparar com o Jabiru, que é ainda maior do que a cegonha-da-madeira e tem as asas totalmente brancas.
Estado de conservação e esforços
The Wood Stork (Mycteria americana) has seen significant fluctuations in its conservation status over recent decades. Once listed as endangered in the United States due to declining populations, primarily in Florida, its status was downlisted to "threatened" in 2014 following population increases and improved nesting success. Despite this positive trend, the Wood Stork still faces numerous threats, including habitat loss due to wetland drainage, changes in water management practices, and climate change impacts. Conservation efforts for the Wood Stork focus on habitat protection and restoration, particularly in key wetland areas in the Southeastern United States. Measures include preserving and restoring hydrological conditions in the Everglades and other wetlands, ensuring these areas maintain the water levels necessary for stork feeding and nesting. Additionally, conservation organizations and government agencies are working to protect nesting sites from disturbance and to implement programs that monitor population trends. These efforts have contributed to a slow but steady recovery of the species, highlighting the importance of maintaining and enhancing wetland ecosystems.
