The white fish catching bird is most likely referring to the Great Egret. The Great Egret is a large, white wading bird that can often be seen standing patiently in shallow water waiting to catch small fish with its long, pointed bill. Great Egrets are skilled hunters and fascinating birds to observe.
What does the Great Egret look like?
The Great Egret is an elegant, statuesque bird that is entirely white in color. Its plumage is long and fluffy, with long, shaggy plumes extending from the back during the breeding season. The bill of the Great Egret is long, straight, and yellow in color. The legs are black and very long, allowing the bird to wade through deep water while hunting. In flight, the Great Egret’s black legs extend past the end of the tail and the long neck is tucked back.
Great Egrets are very large birds, standing over 3 feet tall with a wingspan over 4 feet wide. The male and female Great Egrets look identical. Immature birds look similar to adults but have greenish-black bills and greenish legs instead of yellow and black.
Where does the Great Egret live?
The Great Egret has a very wide range and can be found on every continent except Antarctica. In North America, they breed predominantly in the southeastern United States and down into South America. They can be found along the Atlantic and Pacific coasts, as well as near inland wetlands. During the winter, they migrate south and can be found throughout Central America and the Caribbean.
Great Egrets inhabit shallow wetland areas including marshes, streams, ponds, and swamps. They nest in trees or shrubs near water. Outside of the breeding season, Great Egrets are solitary birds but may gather in large feeding groups of 30 birds or more.
What does the Great Egret eat?
Great Egrets are carnivores that feed mainly on small fish such as minnows, sunfish, shad, and perch. They also prey on amphibians like frogs, salamanders, and newts as well as small reptiles and mammals like voles, mice, shrews, and moles. Aquatic invertebrates including crustaceans and insects may also be taken.
They hunt by standing motionless in shallow water, often with one foot stirred lightly to attract prey. When prey approaches within striking distance, they will spear it with a rapid thrust of their long bill. They may also pursue prey while wading through the water. Great Egrets typically swallow their prey whole.
How does the Great Egret catch fish?
Great Egrets have a number of physical and behavioral adaptations that make them highly effective at catching fish:
- Long, pointed bill – Their bill is narrow, sharp, and over 5 inches long. This allows them to quickly snap up prey.
- Long legs and neck – Their long legs allow them to wade in deeper water than other herons while their S-shaped neck can strike swiftly.
- Stealthy walking – Great Egrets walk slowly and methodically, placing each foot carefully to avoid splashing and scaring fish.
- Standing still – Great Egrets often stand completely motionless, waiting patiently for prey to come near.
- Shading water – Their white plumage will shade and darken the water below, hiding their silhouette from fish below.
- Flapping wings – Great Egrets may use their wings to stir up the water, luring curious fish within striking range.
- Quick reflexes – Once prey is in range, Great Egrets can strike extremely quickly with their bill.
With these adaptations, Great Egrets are well equipped to patiently and methodically hunt fish in shallow waters.
When do Great Egrets breed?
The breeding season for Great Egrets varies across their widespread range:
- Southern populations may breed year round.
- In the United States, they typically breed from March to July.
- Further north such as Canada, they breed May through August.
Nesting peaks from April to June. They typically have only one brood per year. The timing ensures young have the best access to abundant food sources like amphibians and fish that are active in warmer weather.
How do Great Egrets make their nests?
Great Egrets build platform nests high up in trees, often over water. The nests are bulky structures made from a base of sticks and twigs, then lined with softer vegetation. Great Egret nests are typically:
- Located 10 to 30 feet high in trees or shrubs.
- Positioned near the trunk or amongst dense branches for support.
- Made of a loose platform of sticks and twigs.
- Lined with softer grasses, lichens, and moss.
- 1.5 to 4 feet wide.
Both the male and female participate in constructing the nest. Nest sites are typically in trees or shrubs near wetland feeding areas. Nests are often reused and expanded each breeding season.
How many eggs does the Great Egret lay?
A typical Great Egret clutch contains 3 to 5 eggs. The eggs are oval shaped with a blue-green color and measure about 2 x 1.5 inches. The female lays one egg every 1-2 days, and full clutches are completed within a week. Both parents incubate the eggs for approximately 3 weeks before they hatch.
Great Egret Clutch Size
Clutch Size | Frequency |
---|---|
3 eggs | 35% of clutches |
4 eggs | 55% of clutches |
5 eggs | 10% of clutches |
Having 3-5 eggs improves the chances that at least a few eggs will successfully hatch. More eggs buffer the parents against infertility, predators, or damage to individual eggs. 4 eggs is the most common and productive clutch size.
How do baby Great Egrets grow?
Newly hatched Great Egrets are helpless, with their eyes closed and covered in white downy feathers. Both parents feed the chicks by regurgitating food directly into their mouths. The chicks grow quickly on the protein-rich diet of fish, amphibians, and invertebrates.
Within 2-3 weeks, the chicks open their eyes and their wings and bills begin to grow and develop. By 4 weeks old the chicks may stand up in the nest and start to explore. They will fledge and leave the nest at around 6 weeks old but remain dependent on parental care for another 4-6 weeks as they learn to hunt successfully.
The young birds lack the long plumes and instead have yellow-orange bills with a black tip. Their plumage turns fully white by about 14 months old. Great Egrets reach sexual maturity and begin breeding between 1-2 years old.
What are some cool facts about Great Egrets?
- Their yellow slippers! Great Egrets have bright yellow feet unlike the black feet of other white herons.
- That fluffy breeding plumage! In spring, long filmy back plumes grow to attract mates.
- Acrobatic fishing style! Great Egrets may dance, run, leap, or flap wings to corral fish.
- Adaptable habitat use – They forage in both freshwater and saltwater environments.
- Long lifespan – Great Egrets may live 15 years or more in the wild.
- Formerly hunted for plumes – Their decorative plumes were a target of the millinery trade in the late 1800s.
Why are Great Egrets white?
There are a few key reasons why Great Egrets evolved bright white plumage:
- Camouflage – Their white coloration allows Great Egrets to blend into the pale sky when seen from below. This helps disguise them from potential prey.
- Vision – Having dark skin underneath white feathers improves vision by reducing glare while hunting.
- Temperature – White feathers reflect light and heat, keeping Great Egrets cooler while wading in sunny wetlands.
- Breeding – The white color helps Great Egrets identify their own species and may attract a mate.
The white plumage gives Great Egrets several advantages as a wading bird that are worth the tradeoff of being highly visible to predators. Their impressive size also helps deter potential predators.
How does pollution affect Great Egrets?
Great Egrets can be vulnerable to several forms of pollution due to their wetland habitat and fish diet:
- Oil spills – Oil spills directly coat and poison Great Egrets at affected sites.
- Pesticides – Chemical runoff accumulates up the food chain, harming egrets.
- Mercury – Mercury in fish can reduce egret reproduction.
- Plastics – Egrets may ingest plastic debris when catching prey.
Pollution can cause direct mortality of Great Egrets through poisoning. It also reduces the quantity and quality of their food supply and breeding habitat. Maintaining good water quality is important to support Great Egret populations.
How can we help protect Great Egrets?
Here are some ways to preserve Great Egrets and their wetland habitats:
- Conserve wetlands – Support wetland protections and restoration programs.
- Reduce pesticide use – Limit chemical runoff into waterways.
- Trash clean-ups – Clear plastics that can be ingested from shorelines.
