How does a wood stork defend itself?
How do wood storks protect themselves? Wood storks nest in the treetops of cypress or mangrove swamps and, more recently, man-made impoundments. To protect themselves against such predators as raccoons, the birds usually build their nests on islands or in tall trees over water.
Do wood stork have nicknames?
When they are flying they do not tuck their legs up under the bodies like a lot of birds do, but instead will leave then hanging out behind them. The Wood Stork is the generally accepted name for this Floridian wading bird, although due to the appearance of its head and upper neck, you may also hear of it being called “Ironhead” or “Flinthead”.
What is wood stork's predator's?

Despite the myth that Wood Storks mate for life, pairs form at the breeding colony and stay together only for a single breeding season.
What is a group of wood storks called?
They nest above water to prevent predators such as raccoons from feeding on their eggs and young. A group of storks has many collective nouns, including "a clatter of storks", "a filth of storks", "a muster of storks", "a phalanx of storks", and a "swoop of storks."
How many babies do wood storks have?
Reproduction. Wood storks are social animals. They feed in flocks and nest in large rookeries—sometimes several pairs to a single tree. Females lay two to five eggs, which both sexes incubate for about one month.
What do wood storks need to survive?
Tree cover alongside the water provides an ideal spot for colonies of wood storks to build their nests close together. Wood storks are resourceful hunters and will be attracted to sites where they can access the large quantities of fish that they need to survive, such as shallow lakes, mangroves, and tidal creeks.
What do you feed wood storks?

Can wood storks eat bread?
But please don't feed hot dogs or bread to wild birds! It's not good for us and can be deadly to wildlife.) Wood stork PRWC recently admitted a wood stork that had gotten entangled in some recklessly discarded fishing line.
Why is the wood stork important?
The Wood Stork serves as an indicator species for restoration of the Everglades ecosystem. Indicator species serve as excellent messengers of the past, present, and future because their specific habitat requirements are so closely associated with one particular environment.
Do wood storks eat hot dogs?
The three-year study discovered that despite a narrowly evolved diet of fish, wood storks will subsidize their meal plan with fast food favorites such as chicken wings, hot dogs and cold cuts when traditional fare is scarce. The lanky birds also had a taste for penne pasta, chicken nuggets and pollywogs.
Are storks aggressive?
As pairs are formed in the colony there is much aggressive and sexual posturing, although this behavior is not as elaborate or ritualized as in some species of storks. Pair formation behavior serves to stimulate the birds for breeding and synchronize the colony.
How do storks sleep?
Other birds, such as flamingos and storks, can also sleep standing up. Even more impressive is their ability to do so standing on only one leg.
Is a heron the same as a stork?

How big is a wood stork?
The Wood Stork ( Mycteria americana) is a large, bald-headed wading bird that stands more than 3 feet (0.9 meters) tall, has a 5 foot (1.5 meter) wing spread, and weighs 4 to 6 pounds (1.8 to 2.7 kg). It is the only stork breeding in the United States and was placed on the Federal Endangered Species list in 1984. The species was downlisted from endangered to threatened in June 2014, reflecting a successful conservation and recovery effort spanning three decades.
Why are wood storks important?
The Wood Stork serves as an indicator species for restoration of the Everglades ecosystem. Indicator species serve as excellent messengers of the past, present, and future because their specific habitat requirements are so closely associated with one particular environment.
What is the role of wood storks in the Everglades?
The indicator role of the Wood Stork is supported by the total number of all species of wading birds nesting in mainland colonies within the Everglades, which also has declined during the same time period. Since the 1930s, the number of breeding pairs of all wading birds has declined by 90 percent. Clearly, the southern Everglades ecosystem has been incapable of supporting viable populations of Wood Storks and other wading birds for several decades. In addition to documenting the deterioration of the ecosystem, the Wood Stork data provide information that is needed for successful restoration of the ecosystem. Knowledge of the habitat requirements of Wood Storks makes it possible to revise water-management practices to restore suitable feeding conditions for wading birds. The challenge, however, is to implement these improved water-management programs in the face of the rapidly growing human demands for water and space in south Florida.
How to identify wood storks?
A Wood Stork is easy to identify by its black, bald head. The Everglades of the 1930s, largely undrained and without complex water-control structures, supported a nesting of population of 5,000 to 15,000 pairs of Wood Storks. Modern water-control programs in south Florida have so greatly changed the flooding and drying patterns ...
How do storks find food?
A stork locates food -- mostly small, freshwater fish -- not by sight but by tactolocation, or groping with its bill in shallow water. Often the water is muddy and full of plants, conditions that obscure prey from sight. The stork sweeps its submerged bill from side to side as it walks slowly forward.
Why are wood storks so abundant in Florida?
The Wood Stork used to thrive in south Florida because it is a specialized species that prefers tropical and subtropical habitats with distinct wet and dry seasons.
How many pounds of fish do storks need to breed?
Each breeding pair of these large birds requires about 440 pounds (200 kg) of fish per breeding season.
How do wood storks live?
The wood stork's habitat can vary, but it must have a tropical or subtropical climate with fluctuating water levels. The one-metre-diameter (3.3-foot) nest is found in trees, especially mangroves and those of the genus Taxodium, usually surrounded by water or over water. The wood stork nests colonially. The nest itself is made from sticks and greenery. During the breeding season, which is initiated when the water levels decline and can occur anytime between November and August, a single clutch of three to five eggs is laid. These are incubated for around 30 days, and the chicks hatch underdeveloped, or altricial, requiring support from their parents. They fledge 60 to 65 days after hatching, although only about 31% of nests fledge a chick in any given year, with most chicks dying during their first two weeks, despite being watched by an adult during that time. The chicks are fed fish of increasing size. The diet of the adult changes throughout the year. During the dry season, fish and insects are eaten, compared to the addition of frogs and crabs during the wet season. Because it forages by touch, it needs shallow water to effectively catch food. This is also the reason why the wood stork breeds when water levels start to fall.
How big is a wood stork?

How do storks fly?
When it is not sufficiently warm and clear, such as in the late afternoon or on cloudy days, this stork alternates between flapping its wings and gliding for short periods of time. When it is warm and clear, this bird glides after it gains an altitude of at least 610 metres (2,000 ft) through continuously flapping its wings. It can then glide for distances ranging from 16 to 24 kilometres (9.9 to 14.9 mi). It does not have to flap its wings during this time because the warm thermals are strong enough to support its weight. Because of the energy that is conserved by soaring, this stork usually uses this method to fly to more distant areas. It flies with its neck outstretched and its legs and feet trailing behind it.

What do wood storks eat?
Wood Storks primarily eat fish and other aquatic invertebrates, but sometimes take seeds, amphibians, nestlings, and reptiles. They walk slowly through wetlands with their bill in the water, feeling for prey. When they feel something on their bill, they quickly snap it closed, swallowing the prey whole. To find prey they also push their feet up and down in the water or flick their wings to startle prey. Storks also visually search for prey, but more frequently use their bill to feel for it, especially in muddy waters.
How long does it take for a wood stork to build a nest?
Nest building typically takes 2–3 days, but the pair continues to make improvements throughout the nesting period. Creamy white. Nestlings are covered in fine white down except on the head. Wood Storks are social birds that forage in groups and nest in colonies.
Why are wood storks vulnerable to water?
Wood Stork populations are vulnerable to changes in water levels. During dry years or in years when extensive water diversion projects reduce the amount of standing water below nest trees, a colony may forgo nesting. Low water levels can also increase nest predation from terrestrial predators such as raccoons.
How do storks find prey?
To find prey they also push their feet up and down in the water or flick their wings to startle prey. Storks also visually search for prey, but more frequently use their bill to feel for it, especially in muddy waters.

The wood stork was first formally given its binomial name Mycteria americana by Linnaeus in 1758. Linnaeus based his name on a misplaced account and illustration in Historia Naturalis Brasiliae (1648) of the jabiru-guacu. Linnaeus also described Tantalus loculator, which was proven to also apply to the jabiru-guacu, after M. americana based on a 1731 illustration of the wood stork by Mark Catesby under the name of wood pelican. Since these binomials referred to the same speci…
