Wading Birds

Western Cattle Egret

Western Cattle Egret
The Cattle Egret (Bubulcus ibis) is a small, white heron native to Africa. This bird is known for its symbiotic relationship with large grazing animals, most commonly cattle, from which it gets its name.
Cattle egrets are distinctive due to their short necks and sturdy build compared to other egrets. Adults are predominantly white with yellow bills and legs, though, during the breeding season, they develop buff-colored plumage on their heads, necks, and backs. They typically stand 46 to 56 cm (18 to 22 inches) tall with a wingspan of around 88 to 96 cm (35 to 38 inches).
Cattle egrets are often seen following grazing animals and farm equipment. Some may stand on top of a cow or horse. They are insectivorous birds, feeding on insects such as grasshoppers, crickets, flies, and other small creatures stirred up by the movement of these animals and machines. They occasionally consume frogs, birds, small mammals, and other prey when available.
Cattle egrets typically breed in colonies, often alongside other heron species. They construct their nests near water on top of the outer branches of shrubs or trees. The nests are made from sticks and other plant material, and the female lays 3 to 5 pale blue or green eggs. Both parents participate in incubating the eggs and feeding the young.
The cattle egret’s symbiotic relationship with grazing animals makes it a unique ecosystem species. By feeding on insects and pests, it helps reduce parasitic loads on livestock and promotes healthier grazing environments.

Tri-colored heron

Tri-colored Heron (Egretta tricolor) is a sleek and slender bird with a daggerlike bill. They have a long thin neck that curves up to their small head. The Tri-colored heron is a medium size bird that measures up to 23.6-27.6 inches with a wingspan of 37.4 inches and weighs about 14.6 oz. It is a colorful bird with a mixture of blue-gray, lavender, and white. Unlike other dark herons, they have a white belly.
On the Atlantic coast, they will migrate south, whereas on the gulf coast, they remain year-round, though some may migrate further south. Tri-colored Herons can be found in coastal areas and freshwater marshes, lake edges, canals, and ditches during the non-breeding seasons. During breeding seasons, they will use coastal estuaries, salt marshes, mangroves, and lagoons, though they typically breed on islands with small trees or shrubs. Breeding birds have small white plumes extending from the back of the head, a bright blue patch of skin around the bill, and pink legs. Nonbreeding birds lack the colors of breeding birds and have yellow legs. Juveniles have rusty necks and rusty-edged feathers.
These birds forage for small fish, such as topminnows and killifishes, in open or semi-open brackish wetlands. To capture these small fish, they will stalk, chase, and stand and wait. Unlike other heron species, the Tri-colored Heron foraging style is much more active as they will chase after fish with wings flapping. They usually forage alone or at the edge of flocks of wading birds. Despite being solitary foragers, they do nest in colonies, often with other herons and egrets.
Males are aggressive if others come close to their nest site, though females can enter during courtship. Once paired, they formed a monogamous bond for the breeding season and perhaps longer. Males collect twigs for the female, who will rearrange them for the best, making it a bulkier platform. There will typically be about 3-5 eggs in a clutch though only one young typically hatch. Eggs are pale greenish blue. The incubation period is about 21-24 days. Young can leave the nest after 17-21 days after hatching.
Tri-colored Herons are common with a stable population from 1966 to 2015, according to the North American Breeding Bird Survey, though the status of this species differs by state and region. In the central Everglades in Florida, the number of breeding pairs decreased by 75% from 1996 to 2002 and 2007 to 2010, listing the Tricolored Heron as a state threatened by the Florida Fish and Wildlife Conservation Commission. Reduced freshwater flows in the Everglades are likely responsible for population declines there. In other areas, habitat loss may be contributing to declines but increases in aquaculture farming along the coast can also place Tricolored Herons at greater risk of being shot or falling victim to bird repelling techniques. Still, in other areas, increases in artificial wetland habitat through dredging may benefit Tricolored Herons by providing additional nesting locations.

Little Blue Heron

The Little Blue Heron (Egretta caerulea) is a native species of Florida. They are relatively common in peninsular Florida, though they are rare in the panhandle. They can be found in fresh, salt, brackish, swamps, ponds, lakes, and rivers. They can measure 22.1-29.1 inches with a wingspan of 39.4-41.3 inches and weigh up to 10.4-14.5 oz. Juveniles look different from adults; they are white all over, with the exception of their outer wing feathers (outer primaries) which can have some dusky tips. Juveniles molting into adult plumage will be patchy with colorations of blue and white. The adults are dark all over, their head and neck are maroon in color during the breeding season, and during the non-breeding season, it has a purplish head and neck. Their body is a dark slate blue. They have yellow eyes and greenish legs, and the base of their bill is pale blue with a black tip.
The Little Blue Heron is a stand-and-wait predator. They watch the water for prey, changing location by strolling or flying to a completely different site. Their diet consists of fish, insects, shrimp, and amphibians. They are solitary predators preferring to hunt alone, along freshwater systems, and on floating vegetation. However, they nest in colonies on trees among other nesting herons and wading birds. Nests are built out of sticks and are placed in trees and shrubs and will lay up to three to five blue-green eggs that will hatch in 20 to 24 days. The young can leave the nests and fly (fledged) at 28 days of age.
The little blue heron’s current threats are not well understood. Still, they may include coastal development, disturbance at foraging and breeding sites, environmental issues, degradation of feeding habitat, reduced prey availability, and predators. Other threats may include exposure such as pesticides, toxins, and parasite infection. The U.S. Migratory Bird Treaty Act protects this species. Florida’s Endangered and Threatened Species Rule lists them as a state-threatened species.

Wood Stork

The Wood Stork (Mycteria americana) is a large, long-legged wading bird that can reach lengths up to 35-45 inches with a wingspan of 60-65 inches. They are completely white all over with the exception of their black flight feather and tail. The head has no feathers and is essentially bald, the skin is gray, rough, and scaly. They have black bills and black legs with pink toes. Adults are voiceless and are capable of only making hissing sounds.
Wood Storks feed in groups, and their head will be down feeling for prey in open wetlands. Prey consists of small to medium-sized fish, crayfish, amphibians, and reptiles. They have a unique hunting technique, where they will move their partially opened bill through the water, snapping up prey when prey comes in contact with the bill. They fly with their head and legs outstretched, soaring in a similar fashion to a raptor or vulture.
The Wood Stork is the only species of stork that breeds in the U.S. They breed in Florida, Georgia, South Carolina, and North Carolina. They have very social nesting habits and are often seen nesting in large colonies of 100-150 nests. The nests are primarily built in trees that stand in water.
In Florida, Wood Storks can lay eggs from October to June. Two to five eggs are laid in a single clutch per season. The incubation period can last up to 30 days, and young storks can fly at 10-12 weeks. Non-breeding wood storks have a large range throughout North America, to northern Argentina in South America.
The South Florida population has declined due to agriculture expansion and altered hydro cycles. Normal flooding is important to increase the prey population for wood storks, and successful breeding depends on normal hydro cycles. The drainage of cypress stands prevents wood storks from nesting, and it promotes predation from raccoons. The wood stork is protected by the U.S. Migratory Bird Treaty Act and is listed as a threatened species by the Federal Endangered Species Act. Florida’s Endangered and Threatened Species Rule listed the wood stork as a Federally designated Threatened species.

Snowy Egret

The Snowy Egret, Egretta thula, is a medium-sized heron that is smaller than a Great Egret. They have a black bill, a patch of yellow skin on their face, and vibrant yellow feet. They are year-round residents in Florida.
Look for Snowy Egrets near the coast, in wetlands, along rivers and lakes, and in agricultural fields that are wet. Their diet consists of fish, insects, crustaceans, frogs, and worms. They often use their yellow feet to stir up mud to make food accessible. You may find them eating while paddling, walking, running, or standing. They often forage in groups with other species including herons, egrets, ibises, and Roseate Spoonbills.
During the breeding season, Snowy Egrets grow long billowy plumes on their backs and heads. Their feet become a bright yellowish-orange and the skin on their face becomes reddish in color. Male Snowy egrets provide quite a display of courtship that includes loud noises and incredible aerial displays. They will fight to defend their breeding territory.
Nesting occurs at the top of a tree or a shrub at a site chosen by the male. They often nest in colonies with other egrets, herons, Roseate Spoonbills, and ibises. The male builds the foundation of the nest and then supplies materials such as sticks, grasses, and Spanish moss so the female can make it comfortable. The female lays 2-6 eggs that hatch in 24–25 days. They take turns incubating the eggs and both care for the hatchlings for 20-24 days. The pair will defend their young who may be preyed upon by owls, alligators, and crows.
Before plume hunting of Snowy Egrets was stopped in 1910, the population of this beautiful bird was severely compromised. Today the population is stable. However, the massive destruction and degradation of wetlands that have occurred in the last 200+ years put them at risk for food insecurity. For the sake of Snowy Egrets and all wading birds, we must advocate for the preservation and restoration of wetlands and the food sources that lie within them.

Great Egret

The Great Egret, Ardea alba, is a year-round resident in Florida’s wetlands. It is a regal bird that struts proudly while showing off its a long yellow beak and bright white plumage atop ebony legs. In flight, the Great Egret boasts a wingspan of up to 57 inches and gracefully cruises through the sky at 25 miles per hour.
Great Egrets primarily hunt while standing or wading in freshwater, brackish water, or saltwater. Small fish make up most of their diet but they snack on reptiles, amphibians, shrimp, dragonflies, birds, and small mammals.
During the breeding season, you will find colonies of Great Egrets nesting in treetops near water. Males will begin building the nest before pairing with a female. During this time, a green neon patch of skin appears on the Great Egret’s face and long billowy white plumes emerge from its back in anticipation of courtship.
The monogamous couple will complete the nest and the female will produce a clutch of 1-6 eggs. Hatchlings appear in 23-27 days and remain in the nest for up to 25 days. Not all of the chicks will survive the sibling rivalry in the nest as the dominant chick may stab the weaker ones.
More than 95% of Great Egrets were killed when hunted for their plumes. In 1910, plume-hunting was banned and the US population is now considered stable.
Current threats include habitat loss and degradation as well as runoff from sewage and farms. Together, we can advocate for the protection and preservation of the wild spaces where Great Egrets thrive.

Great White Heron

The Great White Heron, Ardea herodias occidentalis, is a wading bird that can only be found in South Florida and The Florida Keys. It is the largest heron. Whether the Great White Heron is a color morph, a subspecies of the Great Blue Heron, or a new species is a topic that is still being researched. However, it has been commonly accepted that this Florida native bird is a subspecies of the Great Blue Heron. Both birds share similar characteristics. The Great White Heron is a larger bird with solid white feathers and yellow legs, while the Great Blue Heron is a smaller bird with blue-gray feathers and black legs. Great White Herons can be distinguished from the Great White Egrets by their larger size, yellow legs vs black legs of the Great White Egret, thicker bills, and coiled neck when flying.
The nesting habitat of the Great White Heron is primarily located in the Great White Heron National Wildlife Refuge and Key West National Wildlife Refuge. About 800–1,300 pairs of Great White Herons breed in the mangrove islands, shoals, and mudflats of Florida Bay and the Florida Keys. Breeding rarely takes place on the mainland of Florida. Nesting occurs throughout the year and peaks between December to February.
Great White Herons forage in turtle grass beds. The tidal cycle limits their access to food because they can only reach it at low tide. The Great White Heron’s habitat has also been negatively impacted by boat traffic through these seagrass beds. Because they inhabit a small geographic area, pollution of their home range and habitat loss caused by human activities, as well as climate change contribute to the ongoing threats to Great White Herons.

Glossy Ibis

The Glossy Ibis, Plegadis falcinellus, is a native wading bird found year-round in Florida. Look for them in freshwater and saltwater marshes, swamps, ponds, lakes, mangroves, and flooded fields. Ibises wade in shallow water where they probe the mud for prey with their long beaks or snatch insects from the water’s surface. Food consists of dragonflies, crayfish, snails, crabs, fish, frogs, lizards, snakes, and more.
Glossy Ibises nest in colonies low in willows and other shrubs, on the ground, or in trees and shrubs near marshes or mangroves. The couple builds the nest and the female lays 3 – 4 eggs. The parents feed the young by regurgitation.
From a distance, Glossy Ibises appear dark. The sunlight will bring out the bronze, metallic green, and purple shades in the plumage.

Great Blue Heron

Great Blue Herons, Ardea herodias, are one of the most recognizable birds in Florida. The heron’s height and beautiful blue-gray plumage are hard to miss. They can reach 54 inches from head to tail, have a wingspan up to 75 inches, but weigh a mere 5-6 pounds.

You will most often find a Great Blue Heron standing alone at the water’s edge in saltwater or freshwater habitats. Fish, turtles, frogs, insects, birds, and rodents that pass within the area of the heron’s long neck are quickly snatched up by its powerful, long beak. Herons will also forage in fields or grasslands for frogs, birds, and small rodents.

During the breeding season, Great Blue Herons and their mates become part of a breeding colony that can include hundreds of pairs. Breeding colonies of Great Blue Herons are most often found in trees that are within 2-4 miles of their feeding areas. They may also be seen in mangroves, bushes, or on the ground. Males court females who lay 2-6 eggs. The couple shares the responsibility of incubating the eggs for up to a month and feeding the hatchlings for up to 3 months.

While Great Blue Heron’s remain mostly monogamous and enjoy the protection of the colony during the breeding season, for the rest of the year, they are solitary birds and will aggressively defend their feeding territory.

Yellow-crowned Night-Heron

Yellow-crowned Night-Herons, Nyctanassa violacea, with their purplish-gray body, black-and-white face, and striking yellow plumes can be found in wet fields or shallow wetlands. They may be seen foraging any time during the day or night. You will most often discover this bird alone, although, at times, they may appear in groups.

Watch as they stand still or walk slowly with their necks extended in search of their favorite dinner of crustaceans. They may also eat frogs, small fish mussels, and water beetles.

Keep a keen eye out for this hard-to-find bird. While they are most common in barrier islands, coastal marshes, and mangroves, you may also find them inland near rivers, on golf courses, or even in your wet yard.

Yellow-crowned Night-Herons have been around for a long time. The oldest recorded fossil was discovered in Sarasota, Florida, and is 2–2.5 million years old.

Sadly, the Yellow-crowned Night-Heron has been designated a Species of Concern by Florida Rare and Endangered Plants and Animals.

Reddish Egrets

Reddish Egrets, (Egretta rufescens), can be found running and jumping in the shallow saltwater of Florida coasts. Estuaries, lagoons, and waters near mangroves provide a variety of small fish that are brought to the surface by the egret’s intricate dance of jumps, spins, and footwork with wings of 46-48 inches spread open.

A dark Reddish Egret is pictured here. You may also discover a white morph that has a mostly white body. They both have a black-tipped pink bill and blue feet and legs.

Reddish Egrets breed in mainland Florida between February and June. Breeding in the Keys and Florida Bay occurs from November to May. Both the male and female incubate three to four eggs for 26 days. The young leave the nest within 45-49 days after hatching.

Plume trading nearly wiped out the Reddish Egrets. The Reddish Egret is currently State designated as Threatened and is protected by the U.S. Migratory
Bird Treaty Act.

Today, the Reddish Egret population may be in decline once again. Development, degradation of habitat, loss of genetic diversity, human disturbance, and predators are cause for concern.

You can be their voice. Advocate for clean water and the protection of land where Reddish Egrets call home. Respect their right to share our state with us. Give them space, observe from afar, and be mindful of where you hike, boat, and play.

Flamingo (American)

American Flamingo

The American Flamingo (Phoenicopterus ruber) stands 3-5 feet tall with a wingspan of up to 50 inches. The bright pink color comes from a diet of snails, crustaceans, crabs, and algae. Without this specific diet, they would turn gray.

The most unusual thing about Flamingos is their tongues. The tongue is encased in the lower jaw and does not move. It squeezes mud through structures in the bill called lamellae. Lamellae act as a strainer to extract insects, brine shrimp, algae, and other small prey.

There has been some debate on whether or not Flamingos are native to Florida. If they are spotted, they are usually considered escapees from captive flocks. During the 1800s, flamingos were considered native to Florida. John James Audubon came explicitly to see Flamingos on his 1830 visit to Florida. By the 1900s, Flamingos had almost completely vanished. They were hunted for food, skin, and feathers.

Flamingos are wading birds and can be found around a water source. They have very long, thin necks and legs. Their heads are small, and their bills are large, heavy, and have a crook. Young flamingos have straight bills, but the crook develops as they age.

The Flamingo stands on one leg to conserve heat as their legs have no feathers. Conserving heat is also why they bury their heads in their feathers. It also makes it easier to stand on one leg and reach down into the water with their bills to catch prey.

American Flamingos are monogamous. The flock will mate simultaneously so the eggs will hatch collectively. The flock protects the young from predators. The mated pair will make a mound of mud, and the female will lay one egg, which is between 3 to 3 1/2 inches long. It hatches in 27 to 31 days. Hatchlings are born white and turn pink within two years. Both parents produce a crop of milk in their upper digestive tract, which they feed to the young until they begin to eat solid food.
Florida has removed Flamingos from the non-native list. Hopefully, flamingos will regain their native species’ status and become subject to federal and state protections.

Conservation efforts to protect Flamingos will be necessary to ensure these birds continue to survive even as they face increasing threats from habitat loss, pollution, and invasive predators. This historical population is in the very beginnings of a recovery. When we work together, we will ensure American Flamingos will not become extinct.

Green Heron

The Green Heron (Butorides virescens) is a solitary, secretive bird. They inhabit coastal areas, mangrove swamps, freshwater ponds, and wetlands.

Green Herons stand with their bodies stretched and horizontal, ready to thrust their bill into prey. They use twigs, berries, and feathers as bait. They drop the bait into the water and wait for it to attract prey. Fish are the primary food, but they also eat aquatic frogs, crustaceans, insects, grasshoppers, snakes, and rodents.

Nests are constructed near water. The male begins building the nest, and the female finishes it. The female lays 3-5 eggs, and both Mom and Dad incubate the eggs for 19-21 days. Once hatched, both will feed the young with regurgitated food. The young learn to fly at about 23 days, but both parents will continue to feed the young until they fledge at about 30 days.

The Green Heron is a dark-colored, stocky bird. They have a dark neck, gray belly, and a greenish, blue back. The upper part of the bill is dark, and the legs are bright orange. Green Heron populations seem to be stable but accurate numbers are difficult because of its secretive nature.

For the Green Heron, the protection of wetlands is especially important.

Roseate Spoonbill

The Roseate Spoonbill (Ajaia Ajaja) is a dramatic comeback bird. Plume hunters had reduced the bird to just 25 in 1901. With the banning of the plume-hunting trade, Florida set a national example for preservation. By the late 1970s, there were nearly 1300 nests. This is an elegant, rose-colored, wading bird with a shovel-like beak. Spoonbills can be found in mangrove swamps, tidal ponds, saltwater lagoons, or other brackish water sources. The bird is 30 to 36 inches tall with a wingspread approaching 3 to 4 feet. Spoonbills have a white neck with pink or rose feathers covering much of its body. The feathers on their wings are bright red to magenta, depending on the age of the bird. The legs are pinkish red. The irises of the eyes of adult birds are bright red.A Spoonbill’s most distinctive feature is the greenish-gray, spoon-shaped beak. On the beak, the nostrils are located near the head, allowing the bird to breathe even with much of its beak underwater. Water must be present for feeding because they can not feed on land. They open their beaks slightly and begin to swing their heads back and forth in the water. This creates small whirlpools, and the vibrations of escaping prey are felt by sensors in the beak. The beak then snaps shut, not allowing the prey to escape. Their prey includes shrimp, crawfish, small fish, insects, and other small mammals. Their red color comes from the red algae ingested along with the crustaceans.

Males are slightly larger than females, but their coloration is identical. March through June is mating season. Spoonbills form mating pairs for the season but not for life. Females attract males by shaking branches with their beaks. The male approaches while nodding his head and attempts to perch next to her. Six days after mating, 2 to 4 eggs are deposited in the nest. Both males and females help incubate the nest and feed the young. The young Spoonbills leave the nest at 8 weeks. They reach maturity at 3 years.

“How can hope be denied when there is always the possibility of an American flamingo or a roseate spoonbill floating down from the sky like pink rose petals?”

White Ibis (American)

The American White Ibis is a very common bird. You may have seen a group of them passing through your yard using their beak to probe for insects. The males tend to be larger with longer beaks. They breed along the Gulf Coast, and when not breeding, they drift further inland and to the Caribbean. These birds are monogamous, and both parents help to take care of the young. Aside from garbage, the larges threat to these birds is methylmercury that leaks into the environment. This alters the hormones in the birds and interferes with their reproduction and breeding. Methylmercury concentrations are increased when waste and fossil fuels are burned. Reservoir flooding can also cause an increase. This chemical is neurotoxic and also inhibits part of the endocrine system. It prevents males from producing sex hormones that would lead to courtship behaviors. Courtship behaviors are significant in most birds. Without these behaviors, the females will not find an interest in the males, and reproduction will not occur. It can also lead to females abandoning their nests and reduced foraging.

Other threats include harvesting their food sources such as crayfish, hunting, habitat degradation, and other chemical uses. If you see these birds passing through, know that they will help your yard by removing pest insects. If you see smaller brown ibis, those are juveniles.
