Field Guide 1966 - Birds - Bufflehead page finished. Awkward waddling ex-nest users...

Habitat

Buffleheads are migratory, and spend the winter in inland waters or protected coastal waters such as shallow bays, sheltered coves, harbors, coastal lagoons, and estuaries, and breed in wooded lakes and ponds in northern taiga habitats. They nest in cavities of aspens or poplars close to small lakes or permanent freshwater ponds and marshes, and have been known to nest in priaries when trees and water are nearby. Their small size allows Buffleheads to use the nesting cavities left by Northern Flickers, and their habitats coincide.

Field Guide 1966 - Mammals - Virginia Opossum page finished. More defenses than just "playing possum."

Habitat

The Virginia Opossum is native to the southeastern United States, and was introduced into the West during the 1930s as a food source. The Virginia Opossum has been successful inhabiting the Pacific coast, and is expanding its range into Canada.

It lives in a variety of habitats such as deciduous forests, prairies, marshes, swamps, farmlands, and even cities, and prefers areas near water. The Virginia Opossum is equally at home on the ground and in trees, and prefer dens in hollow logs, tree cavities, woodpiles, rock piles, crevices, under buildings, in attics, and in underground burrows left by other mammals.

Field Guide 1966 - Birds - Northern Harrier page finished. Check out that bit about kleptoparasitism!

Habitat

Northern Harriers prefer open wetlands, meadows, pastures, prairies, plains, sloughs, marshlands, swamps, grasslands, croplands, shrublands, savannas, desert steppes, and riparian woodlands. Large forest clearings serve as preferred hunting grounds, and they prefer low perches such as stumps or fence posts.

They make their nests on the ground, usually near water, or in tall grass. Occasionally Northern Harriers will make their nest on the water, using a foundation of sticks, willow, or sedge.

Field Guide 1966 - Arthropods - Goldenrod Crab Spider page finished. Who knew they had such interesting camouflage abilities?

Habitat

The goldenrod crab spider can be found all over the Northern Hemisphere, and it gets its name from the goldenrod sprays in which it hunts during the autumn. Other hunting grounds for this spider include spotted joe-pye weed, ox-eye, spotted jewelweed, evergreen blackberry, common milkweed, queen anne's lace, common dandelion, black-eyed susan, bird-foot violet, bushy aster, swamp rose mallow, and common mullein.

Goldenrod crab spiders can range from yellow to white, depending on their current flower, and can change their color to blend in with their current flower species. This spider does not use a web to capture its prey, but does produce webbing as a safety line, and also for creating egg sacs.

Field Guide 1966 - Mammals - Elk page finished.

Habitat

Elk, or wapiti, thrive in forest-edge habitat. Elk prefer open woodlands over dense forests, but can also be found in coniferous swamps, clear cuts, and hardwood forests. They migrate to higher altitudes in the spring, and lower altitudes in the fall. In the winter, wooded areas with plenty of tree bark and valleys sheltered from the wind are sought by the elk. Elk enjoy a home range of up to 600 square miles.

Once found extensively throughout the Northern Hemisphere, hunting and habitat loss have restricted elk populations to a fraction of their former range.
