How many species of herons are there in the world?
There are about 60 species of herons distributed throughout most of the world, except in the extreme northern and southern regions. Herons are most common in the tropics. Herons, bitterns and egrets are closely related, belonging to the family Ardeidae of the order Pelecaniformes. The term “heron” is used sometimes to embrace the family group. Other close avian relatives include ibises and spoonbills. Herons are wading birds with long, slender legs, long necks and long, heavy bills tapering to a sharp point. Their wings are broad and rounded, their tails short. Most herons, especially the larger ones, are graceful in form and movement.
What kind of herons breed in Pennsylvania?
The following herons and allies, which breed in Pennsylvania, are covered in this Wildlife Note: American bittern, least bittern, great blue heron, great egret, green heron, black-crowned night-heron, yellow-crowned night-heron. For more detailed information about these listed species, please see the agency’s endangered species web page. All of these herons are migratory, generally breeding in northern areas and migrating south in autumn. Some species migrate in flocks, some in small bands, and some individually.
Why are herons important to Pennsylvania?
Herons, and many other species of wildlife, benefit from Pennsylvania Game Commission waterfowl projects and habitat preservation and enhancement work on State Game Lands. Wildlife Management Areas such as Pymatuning, Middle Creek and Shohola Lake (SGL 180) provide many acres of excellent marsh and habitat. Propagation areas within these waterfowl management areas restrict public access which provides greater protection to waterfowl, herons and other wildlife, especially during the breeding season. These protected spaces are critical to many bird species, particularly endangered species and species of conservation concern, which are most sensitive during nesting, brooding and raising young. Also, the Game Commission owns and manages some of the largest wetlands in the state which are critical nesting and foraging areas for herons and other birds that require that habitat. Several of these wetlands and larger heron colonies have been selected as state Important Bird Areas. Heron nesting colonies are especially important to protect because they concentrate a population into a small area. Herons literally put all their eggs in one basket, so it is important to protect each “basket.” Therefore, heron colonies are protected through the Natural Heritage Program and the Environmental Review process. These colonies are monitored through the Game Commission’s colonial waterbird program. The American bittern, least bittern, and great egret are considered endangered in the state due to their rarity and the vulnerability of their colonies.
What do green herons eat?
Its call is a sharp, descending skeow, sometimes given in flight. The green heron feeds on small fish, frogs, insects, worms, lizards and salamanders, hunting early in the morning and late in the afternoon. Herons employ some 36 feeding behaviors and the green heron is one of the few birds to use tools among its hunting techniques. While foraging, it may lure prey in by dropping a twig, feather, worm, insect or other bait onto the surface of the water. It then waits motionless, with head and neck retracted and ready to strike, until fish or other prey comes to the bait. This heron also slowly stalks shallow water and stream banks; nudges prey into a more favorable position with its feet; waits perfectly still in ambush; and dives into water from an overhanging perch.
Why are herons endangered?
At one time herons were killed for their plumage, which was used to decorate women’s hats and other clothing. Today, habitat loss is the primary human-influenced threat to herons, especially loss of wetland, riparian and coastal habitats. Degraded and acidic rivers also negatively affect heron populations. All migratory birds are protected under the federal Migratory Bird Treaty Act of 1918.
What do herons do when their parents regurgitate their food?
Later, they bring partly digested food, and finally whole fish, frogs, snakes and other items. A growing heron or bittern will grasp the base of its parent’s bill in a scissors-grip and wrestle with it. This triggers an impulse in the adult either to drop or regurgitate the food.
How do herons adapt to water?
Certain adaptations help a heron wade about and catch prey in shallow water. The most obvious is its legs, which elevate the bird above the water’s surface. The toes are long and flexible for walking or standing on soft ground. The bill is sharp-tipped, and is used mostly for grasping, but is sometimes used to impale prey. The long, muscular neck delivers a lightning-quick blow, with plenty of force to penetrate the water and seize a fish.
