The echolocation calls they make, similar to clicking noises, bounce off objects and this echo is processed by the bat to get the information they need. In strong wind, Snowy Owls may seek shelter by crouching on the ground behind a windbreak, such as a pile of stones, snowdrift, or bale of hay. Unlike seals and sea lions, the Sea Otter has little body fat to help it survive in the cold ocean water. This not only helps keep them warm, but also hides them from predators.

Both terms are from the Latin: Bonasa means good when roasted and umbellus, a sunshade. This refers to the ruff or dark-coloured neck feathers that are particularly large in the male. Nests are shallow depressions in the leaf litter, often at the base of a tree, stump or bush, and normally located in second growth hardwoods. It has large, triangular flippers, or pectoral fins. The table below lists the 14 families of marine birds and the approximate number of species in each (the exact number of species is continually being revised as genetic research reveals that some very similar-looking birds are so different in their genetic makeup that they constitute different species). When they are ready to mate, hens are attracted by a drummer and will mate with him. Their long forked tail and pointed wings also make them easily recognizable. Revised edition. Though good fliers, grouse seldom fly more than a couple hundred yards before either landing in a tree or on the ground to run into a thicket to hide. Unique characteristics. Bent, A.C., editor. Like other reptiles, they are ectothermic, or “cold-blooded”, meaning that their internal temperature matches that of their surroundings. The established birds are secure because they have obtained a place that will provide food and shelter from weather and predation. The hen leaves the nest with her brood of young within a day after they have hatched. Non-parasitic lamprey feed on organic material and detritus in the water column. Studies suggest that the early mortality may be largely due to the type of eggs produced by the hen. Like belugas, they have a small head, a stocky body and short, round flippers. The Giant Pacific Octopus is the largest species of octopus in the world. Males also have a concealed neck ruff (hence the name "ruffed grouse") that they display during courtship. Other older and established grouse are deeper within the forest, where hunters have less success. Dense and relatively stable grouse populations seem to occur most frequently in forests on rich soils. Scientific name: Bonasa umbellus. Anatomy of the Giant Pacific Octopus' head, Common Raven showing its hackles and large beak, North American Lobster Showing Its Different claws, Northern Giant Pacific Octopus (30 seconds), Northern Giant Pacific Octopus (15 seconds), Sharp-shinned Hawk, Cooper's Hawk, and Northern Goshawk, Boreal Chorus Frog (left), Western Chorus Frog (right), can hover and make complete turns in the air when flying through thick bush, attracts females and warns off other males by making a drumming sound with his wings, does not migrate, living all its life within a few hectares, can spread its toes to help it travel over deep, soft snow. Back to top. The male establishes himself among other male grouse by drumming and fighting. The gulls are a family of birds that live mainly at sea, either along the shore, or out in the ocean itself. The displaced grouse, usually young, are forced into habitat where food and cover are inadequate, and more of them die in winter. However, habitats are deteriorating for bobwhite quail and grouse which are dependent upon early successional conditions. When hare populations are high, predator populations increase too. A raven may live up to 21 years in the wild, making it one of the species with the longest lifespan in all passerine birds. It can fly from very close to the ground or water to more than 30 m heights. Catkins and the buds of such broad-leaved trees as poplars, birch, hop-hornbeam, and alders are its staple winter food. Color phases range from gray to chestnut. Its exact colour varies between individuals and seems to depend on its habitat in order to camouflage, or blend in: when there’s lots of algae around, a cod can be reddish to greenish in colour, while a paler grey colour is more common closer to the sandy bottom of the ocean. This line is actually a sensory organ that helps fish detect vibrations in the water. Food is then brought to the first of the lobster’s two stomachs, which is just inside its mouth! Both Pacific and Atlantic Cod have a white line on each side of their bodies from the gills to their tails, or pectoral fins. The scientific name for the Ruffed Grouse is Bonasa umbellus. Females tend to be slightly larger than males but are otherwise identical. The deciduous forest habitat of the Ruffed Grouse occurs right across Canada from east to west, and from Alaska in the north to northern Georgia in the south. Lampreys are an amazing group of ancient fish species which first appeared around 360 million years ago. Signs and sounds The Semipalmated Sandpiper’s voice is a single note chit or cheh. Grouse can often be seen along the sides of gravel roads near these young forest thickets where they pick up grit (small stones) to aid in digestion. Similar in appearance, male grouse are slightly larger than females (hens) possessing long, shiny, black neck feathers. There are two species of chorus frogs here in Canada: the Boreal Chorus Frog (Pseudacris maculata) and the Western Chorus Frog (Pseudacris triseriata). But while it is average-sized, it’s far from average-looking! Some birds, however, exhibit a combination of both colors. Description. In winter, ruffed grouse have comb-like fringes on their toes that, like snowshoes, allow for easy travel on snow. The size of an adult raven may also vary according to its habitat, as subspecies from colder areas are often larger. Its body is divided in two parts: the cephalothorax (its head and body) and its abdomen, or tail. Ruffed Grouse can digest bitter, often toxic plants that many birds can’t handle. The Cooper’s Hawk is intermediate in size; the male Cooper’s is easily confused with the female Sharp-shinned Hawk, and the female Cooper’s Hawk is almost as large as the male Northern Goshawk.

Hunting by humans has little effect on numbers. Adults tend to live only for one year, but some have lived as many as three years. The young of the year are smaller than the adults and have grey plumage, pinkish beaks with black tips, and pink legs and feet. Unlike other cetaceans –the order which comprises all whales–, narwhals have convex tail flukes, or tail fins. In autumn, when the young are almost fully grown, there is another period of relatively intense activity. Its name in French is more straightforward; baleine noire, the black whale. The Cornell Lab will send you updates about birds, birding, and opportunities to help bird conservation. (2000). The fish have hooked jaws and sharp teeth. The change to the greyish-brown fall-winter plumage usually starts on the breeding grounds and is completed after arrival on the non-breeding area. The Ruffed Grouse (pronunciation: ruft growz) is a North American grouse that hovers through the woodlands, and are hard to locate. Ruffed Grouse’s popularity as a game bird led to some of North America’s earliest game management efforts: New York had a closed season (no hunting in part of the year) on Ruffed Grouse starting in 1708. Considering its weight, it’s fairly short, giving it a stocky, rotund appearance. Ruffed grouse come in two basic color phases.
