Yes, there are several species of egrets that can be found in the Philippines. Egrets are medium to large sized waterbirds that belong to the heron family Ardeidae. The most notable egret species in the Philippines include the Great Egret, Intermediate Egret, Little Egret, Chinese Egret, and Cattle Egret. These graceful white birds frequent wetlands across the archipelago and are a familiar sight in flooded rice fields, fish ponds, marshes, and along riverbanks.
Egrets are migratory birds that breed in the Philippines primarily during the dry season from October to April. Some egret species like the Great Egret and Intermediate Egret are widespread across the main Philippine islands of Luzon, Visayas, and Mindanao. Meanwhile the range of other species like the Chinese Egret is limited to parts of Luzon. The Philippines provides important wetland habitats for egret feeding and nesting sites during their breeding season and migration through Southeast Asia.
Great Egret
The Great Egret (Ardea alba) is the largest and most widely distributed egret species in the Philippines. It is an elegant white waterbird reaching 80-100 cm in height with a wingspan of 131-170 cm. It has all white plumage, a long neck, black legs and bill, and black facial skin extending behind the eyes during the breeding season.
Great Egrets occur throughout the Philippines in a wide variety of wetland habitats. They are found along the coasts, in rice fields, marshes, rivers, ponds, lakes, swamps, and fish pens. Great Egrets typically forage in shallow water stalking prey which includes small fish, amphibians, reptiles, and invertebrates.
These egrets breed in mixed colonies with other waterbirds like herons, cormorants, and egrets. Breeding peaks from November to March in the Philippines. Great Egrets build platform stick nests high up in trees near water. The female lays 3-5 bluish-green eggs which hatch after about 25 days.
Great Egrets are classified as Least Concern on the IUCN Red List but face threats from habitat loss and degradation throughout their range. They are protected under the Philippine Wildlife Act and international agreements like the Convention on Migratory Species (CMS) which the Philippines is party to.
Population and Distribution
Great Egrets are resident and migrant birds found across the Philippines including the major islands of Luzon, Visayas, and Mindanao. Their population is estimated at 10,000-100,000 mature individuals in the Philippines. Great Egrets likely have a stable population trend although their status requires better monitoring.
Threats
Great Egrets face threats from:
- Wetland loss and degradation from conversion to agriculture, aquaculture, pollution, urbanization
- Disturbance of nesting colonies
- Hunting and poaching for decorative plumes
Conservation
Conservation actions needed to protect Great Egrets include:
- Preserve wetlands through protected areas and sustainable management
- Community education programs
- Anti-poaching enforcement
- Monitor population trends
Intermediate Egret
The Intermediate Egret (Mesophoyx intermedia) is a medium-sized all white egret that inhabits wetlands across the Philippines. Adults reach 56–66 cm in height with a wingspan of 88–106 cm.
Distinguishing features include an all white plumage, yellow bill that has a dark tip during breeding season, black legs, and lores (region between eye and bill). The Intermediate Egret is smaller than the Great Egret.
This species frequents marshes, flooded fields, rivers, lakes, fish ponds, and other wetlands. It feeds mainly on fish, frogs, crustaceans, and insects which it spears with its bill.
Intermediate Egrets breed January-April, forming colonies with other waterbirds. Their nests are stick platforms built in trees or reedbeds. The female lays 3-5 eggs which incubate for around 23 days.
Their population status in the Philippines is not well known but likely stable. The species faces similar threats and conservation needs as the Great Egret.

The Chinese Egret (Egretta eulophotes) is a medium-sized egret endemic to East Asia. In the Philippines, it is restricted to Luzon island, particularly wetlands in the Candaba area.
The Chinese Egret measures 55–65 cm in height with a wingspan of 95–105 cm. Distinctive features include a slim black bill, long white neck with two long white plumes extending from the lower neck during breeding season, black legs and yellow facial skin.
This species frequents marshes, ponds, flooded fields and rivers. It feeds on fish, frogs, small vertebrates and invertebrates. Chinese Egrets breed January-April in mixed colonies with other waterbirds. The nest is a platform of sticks in trees or reedbeds.
The Chinese Egret has a small global population estimated at just 2,500-10,000 mature individuals. In the Philippines, its population is estimated at less than 1,000 birds. The species is classified as Vulnerable and threatened by habitat loss. Strict protection of wetlands like Candaba is needed for its survival.
Population and Distribution
Most of the Philippine population is concentrated in the Candaba wetlands in north-central Luzon. Smaller numbers occur at other wetlands on Luzon. The total Philippine population likely numbers less than 1,000 individuals.
Threats
Major threats include:
- Habitat degradation at key wetlands
- Drainage for agriculture and development
- Disturbance from fishermen and farmers
- Pesticide pollution
Conservation
Conservation priorities for the Chinese Egret are:
