To finish up his Second Class rank requirements for Boy Scouts recently, I was helping my little man find photographs of wildlife that he has observed. As we dug through our photo archives, I was reminded of a fun little Oregon Nature Quiz: Early Summer Edition that I posted several months ago. I had posted it with the intention of making it a quarterly series but sadly, life distracted me and I let it slip my mind.
Oregon Nature Quiz #2: Wildlife Edition
How Well Do You Know Oregon?
1. North American Raccoon tracks along the banks of a river
In the wild, raccoons often dabble for underwater food near the shore-line. They then often pick up the food item with their front paws to examine it and rub the item, sometimes to remove unwanted parts. This gives the appearance of the raccoon “washing” the food.
Originally, raccoon habitats were solely deciduous and mixed forests, but due to their adaptability they have extended their range to mountainous areas, coastal marshes, and even urban areas. Though previously thought to be solitary, there is now evidence that raccoons engage in gender-specific social behavior. Related females often share a common area, while unrelated males live together in groups of up to four animals to maintain their positions against foreign males during the mating season, and other potential invaders.

2. Pacific Tree Frog
Pacific tree frogs are common on the Pacific coast of Oregon and Washington. They occur in shades of greens or browns and can change colors over periods of hours and weeks. They occur in shades of greens or browns and can change colors over periods of hours and weeks. Eggs of the Pacific tree frog may be consumed by the rough-skinned newt and other amphibians.
They are found upland in ponds, streams, lakes and sometimes even further away from water. The Pacific tree frog makes its home in riparian habitat, as well as woodlands, grassland, chaparral, pasture land, and even urban areas including back yard ponds.
3. Black Bear claw marks and Acorn Woodpecker holes on the trunk of an apple tree
In the early fall, when the apples are ripe, it is not uncommon to see claw marks on apple trees, particularly in old pioneer orchards that have been abandoned. Brown and American black bears are generally diurnal, meaning that they are active for the most part during the day, though they may also forage at night.
Most bears have diets of more plant than animal matter and are completely opportunistic omnivores. Knowing when plants are ripe for eating is a learned behavior. Bears may mark territory by rubbing against trees and other objects which may serve to spread their scent. This is usually accompanied by clawing and biting the object.

4. Golden Mantle Ground Squirrel
Scientists classify the golden-mantled ground squirrel as a true ground squirrel, though it will climb trees to reach seeds. Its genus name Spermophilus is Greek for “seed loving.” Like other ground squirrels, the golden-mantle packs seeds and fruit in its cheek pouches and stores the food in burrows, puts on a thick layer of fat, and hibernates in winter. Golden-mantled ground squirrels eat their stored food in early spring, when seeds and fruit are scarce. In addition to seeds and fruit, the omnivorous ground squirrel eats fungi, insects, bird eggs, small vertebrates, and carrion.
Though the golden-mantled ground squirrel can vocalize, it remains silent most of the time. When alarmed, it chirps and squeals. Though not especially aggressive, it growls when fighting with other ground squirrels. Though tempting, it’s not a good idea to feed these or any other wild animals; it distracts them from searching for natural foods, which they must eat in large quantities to survive. Unlike most other ground squirrels, the golden mantle is a loner. It only spends time with others of its kind as a youngster with its mother and siblings.
5. North American Beaver teeth marks on the trunk of an oak tree
Beaver (Castor Canadensis) are known for building dams, canals, and lodges (homes). Their colonies create one or more dams to provide still, deep water to protect against predators, and to float food and building material. While they don’t generally use trees of the size pictured here in their dams, it is fascinating to watch the process of a beaver dam under construction which play a critical role in the ecology of our streams.
