The differences that Great Egrets display between males and females are extremely subtle and can be challenging to discern without close observation. In terms of plumage coloration, male and female Great Egrets are generally similar. Males have a slightly longer bill and neck than females, but this difference is often challenging to detect in the field without direct comparison.
To determine the sex of a Great Egret with more certainty, researchers and ornithologists often rely on genetic testing or other specialized techniques as these birds show little to no sexual dimorphism even in their behavior and vocalization. However, there are some subtle differences and roles that you can observe during the breeding season.
- Feet Color: As the breeding season approaches, the legs and feet of the male Great Egrets may transition from their usual black color to a more vivid, neon-green shade. This transformation is brought about by changes in the pigments of the skin on their legs.
- Courtship Displays: Males are often more active in initiating courtship displays. They may present twigs to the female, engage in mutual bill-poking, and engage in mutual preening to strengthen their pair bond.
- Incubation: Females tend to spend more time incubating the eggs than males. However, males will also take turns incubating the eggs, especially during short breaks when the female leaves the nest to forage.
- Feeding: Males are often responsible for bringing food to the female while she is incubating the eggs. This helps the female conserve energy and ensures that she can continue to incubate the eggs without the need to leave the nest frequently.
Range And Habitat

The Great Egret is a widespread bird species with a broad range that spans various continents. Its natural range includes North and South America, Europe, Asia, Africa, and Australasia.
They are highly adaptable birds and can be found in a variety of wetland habitats across their extensive range. Here are some of the key types of habitats where you can commonly find Great Egrets.
- Freshwater Wetlands: Great Egrets are mostly associated with freshwater wetlands, including marshes, swamps, and lakes. You can see them wading in shallow water, patiently hunting for fish, amphibians, and other aquatic prey.
- Coastal Habitats: Coastal areas, such as estuaries, tidal flats, and lagoons, are prime habitats for Great Egrets. They forage along the shoreline, taking advantage of the rich diversity of marine life found in these areas.
- Rice Fields: In some regions, Great Egrets are attracted to rice fields, especially during the planting and harvesting seasons when they can easily access small aquatic prey in flooded paddies.
- Islands: On some coastal and inland islands, Great Egrets establish breeding colonies, often in the company of other wading bird species.
- Urban and Suburban Areas: Great Egrets are adaptable and can be found in more developed areas, including golf course ponds, retention basins, and other bodies of water near human settlements.
Dietary Habits

These Egrets are primarily carnivorous birds with a varied diet, and their dietary preferences consist of a wide range of entities.
- Fish: Fish is a staple in the diet of Great Egrets. They are skilled anglers and use their long, sharp bills to capture a variety of fish species, often wading in shallow water or stalking fish near the water’s edge.
- Amphibians: Great Egrets also consume amphibians, including frogs and toads. They wait patiently near the water’s edge and strike quickly when amphibians come within reach.
- Crustaceans: Crustaceans such as crabs, crayfish, and shrimp are commonly on the menu for Great Egrets.
- Insects: They often snatch aquatic insects from the water’s surface or from vegetation near the water.
- Reptiles: While less common, Great Egrets will also feed on reptiles, including small snakes and lizards. They are opportunistic and will take advantage of available prey.
- Small Birds: On occasion, Great Egrets capture small birds, such as chicks and nestlings, particularly in breeding colonies.
Vocalization
Great Egrets are relatively quiet birds, however, they do produce a few distinctive sounds and calls. Let’s check out some of the vocalizations and sounds that Great Egrets make.
- Guttural Croaks: During the breeding season, they produce a series of guttural, low-pitched croaks. These croaks are often part of their courtship and nesting communication.
- Alarm Calls: In response to potential threats, they emit a series of harsh squawks or high-pitched calls. These alarm calls serve as a warning to other members of the colony and can indicate distress or disturbance.
- Contact Calls: When communicating with their mate or young, they use soft, low-frequency contact calls. These are quieter and less intense than the alarm calls.
Breeding Habits

The breeding cycle of Great Egrets is influenced by environmental factors, such as location and climate. However, in general, their nesting behavior follows these stages.
Pair Formation
Courtship activities begin in late winter or early spring as Great Egrets return to their breeding colonies. Males initiate courtship displays, which can include bill-poking, twig offerings, and mutual preening. Pair formation occurs as males and females select mates for the breeding season. Once pairs are established, they work together to build or refurbish a nest.
Nest Building
Nest building is a cooperative effort by both male and female Great Egrets. They build a platform of sticks in tall trees or reed beds near water. The nest-building process typically takes several weeks, with both partners collecting materials and arranging them to create a suitable nesting site.
Egg Laying
After the nest is prepared, the female begins to lay a clutch of eggs. Great Egrets usually lay one to six eggs, with the typical clutch size being three to four eggs. The eggs are usually laid a few days apart, and incubation starts after the first egg is laid. The eggs are pale blue or greenish in color.
Incubation
Both the male and female take turns incubating the eggs. The incubation period lasts for approximately 23 to 27 days. During incubation, one adult will remain in the nest while the other forages for food. They switch roles periodically.
Hatching and Rearing
Once the eggs hatch, both parents are responsible for feeding and caring for the chicks. They are covered in white down feathers, and their eyes are initially closed. As they grow, their down is gradually replaced by juvenile plumage.
Fledging
After about 45 to 55 days, the chicks are ready to leave the nest. At this point, they develop their flight feathers and are capable of short flights. After they leave the nest the young birds learn to forage on their own.
At the end of the breeding season, Great Egrets sometimes disperse from their breeding colonies and begin their migration to wintering grounds. The timing of this post-breeding movement depends on location and environmental conditions.
Here I’ve compiled a simplified chart summarizing the nesting information for Great Egrets.
Number of Broods | One per season |
Clutch Size | 1 to 6 eggs, typically 3 to 4 |
Egg Length | 5.2 cm (2 in) |
Egg Description | Pale blue or greenish |
Incubation | 23 to 27 days |
Fledging | 45 to 55 days |
Hatchlings’ Weight | 30 to 35 g (1.1 to 1.2 oz) |
Behavior
Great Egrets exhibit a range of behaviors that are characteristic of their wading bird lifestyle and social interactions. Let’s read about some key behaviors associated with Great Egrets.
- Wading: Great Egrets are expert waders. They slowly and stealthily move through shallow water, hunting for fish, amphibians, and other aquatic prey. Their slow and deliberate steps minimize water disturbance, making it easier to capture prey.
- Hunting: They employ a patient hunting strategy. Great Egrets stand still for extended periods, waiting for prey to come within striking distance. When a suitable target is detected, they use their sharp bills to quickly grasp it.
- Flight: In flight, Great Egrets display grace and elegance. Their wings are broad, and they typically fly with slow, steady wingbeats. They extend their necks during flight, creating a distinctive S shape.
- Social Behavior: Great Egrets often congregate in colonies during the breeding season. These colonies can consist of various wading bird species. Within these colonies, they engage in behaviors such as courtship displays, mutual bill-poking, and mutual preening.
- Migration: They are migratory birds in many regions and undertake seasonal migrations to find suitable foraging and breeding habitats.
- Self-Grooming: Like most birds, Great Egrets engage in self-grooming to keep their plumage in good condition. They use their bills to clean and preen their feathers.
- Regurgitation: Great Egrets use regurgitation to feed their young. They partially digest food and then regurgitate it into the mouths of their chicks.
Physical Adaptations
Great Egrets possess a range of adaptations that enable them to thrive in their wetland habitats and fulfill their ecological niche as wading birds. Here are some unique adaptations of these Egrets.
- Long Legs and Neck: Their exceptionally long legs and necks are essential for wading in shallow water and reaching their prey with precision.
- Slender Bill: Their long, slender bill allows for efficient striking and capturing of fish and other aquatic prey.
- Webbed Feet: Their feet are webbed, which aids in swimming and provides stability when wading in the water.
