Winter is finally upon us and snow is swirling everywhere. Over the past couple of weeks, my VIPKID students have been sharing photos of the snowmen they have built and I have lamented that we have nothing but rain here on the Oregon coast. On President’s Day, however, we woke up to a light dusting of snow and intermittent snowfall throughout the day. What fun!

Oregon Nature Quiz #3: Winter Wonderland Edition

It’s been a while since my last nature quiz — and the new snow has brought inspiration. Here are five of the photos showing evidence of wildlife action in the depth of winter (albeit not all in the snow). Can you identify the wildlife represented here?

Answers:

1. When we lived in Redding, one of our most anticipated nature outings was our annual ladybug hike. It was always fascinating to see the ladybugs hibernating – hundreds of thousands of ladybugs all gathered in one place. Ladybirds hibernate through the winter as adult insects. Different species will usually hibernate in different places; some shelter under tree bark, others sleep under leaf litter, etc. Have you oberseved ladybugs hibernating in a similar fashion? Some will even gather around window crevices, buildling siding, and wooden structures.

2. The cone of a Pinus ponderosa that has been broken apart by a squirrel for the nuts. Most recently, my daughter has given the art of taxidermy a try. A squirrel was her first specimen – results have not yet been reported.

3. Pictured here is a cougar (Puma concolor) track in the mud. Native to Oregon, cougars range throughout the state, the highest densities occur in the Blue Mountains in the northeastern part of the state and in the southwestern Cascade Mountains. This photo was taken in the coastal range while we were hanging buckets for sugaring time. Cougars are territorial animals and maintain home ranges of up to 100 miles. Most active at dawn and dusk, cougars are lone hunters. They are generally solitary animals, except for mothers who remain with kittens for about two years.

4. There were no other nearby tracks so I am not certain, but I believe these bird tracks may be eagle simply due to their size. What do you think? When we lived in Redding, we loved to watch the resident eagles near the Sundial Bridge. The bald eagle (Haliaeetus leucocephalus), our national bird, is the only eagle unique to North America. It’s scientific name signifies a sea (halo) eagle (aeetos) with a white (leukos) head. At one time, the word “bald” meant “white,” not hairless. Bald eagles are found throughout most of North America, from Alaska and Canada to northern Mexico – with about half living in Alaska. The northwest coast is by far their greatest stronghold for bald eagles. They flourish here in part because of the salmon. Dead or dying fish are an important food source for all bald eagles.

Read my earlier post on Exploring Animal Tracks and learn how to use tracks to tell a story. Make animal track stencils and get out fabric paints to decorate t-shirts.

5. Did you guess rabbit? Six species of rabbit like mammals (these include, rabbits, pikas, and hares) can be found in various habitats throughout central Oregon where this photograph was taken. These small mammals feed primarily on grasses and forbs, have at least two litters per year, and are usually found where there are good amounts of concealing cover available. The shrubs under which they take cover are an important food source and conversely, they serve as the primary prey for many carnivores.

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.

Here are five of the photos my son selected to submit to his Scoutmaster. Can you identify the wildlife represented here?

Answers:

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. Learn more in my post, The Industrious Beaver: Nature’s Engineers.

I have always loved the outdoors and enjoy sharing my passion for nature study with others. I’ve recently completed my coursework to become a certified Oregon Master Naturalist.

To celebrate, I thought it would be fun to create a little quiz to help you get to know Oregon a little better. My vision is to create a new quiz every quarter.

Oregon Nature Quiz #1

How Well Do You Know Oregon?

Here are five photos of plants and animals that are found on the Oregon Coast. Can you identify them? (Hint: All of these photos were taken on the Oregon coast)

What kind of rodent is this?

2. What is this creepy looking black thing?

3. Can you name this flower?

4. Is this cutie a lizard or amphibian? Can you identify the genus?

5. This invertebrate is a common sight along the trails and even in our gardens. What is it?

Answers:

1. The California ground squirrel (Otospermophilus beeches) is pictured here on the rocky shoreline in Depoe Bay. The squirrel’s upper parts are mottled, the fur containing a mixture of gray, light brown and dusky hairs; the underside is lighter, buff or grayish yellow. The fur around the eyes is whitish, while that around the ears is black. Head and body are about 30 cm long and the tail an additional 15 cm. As is typical for ground squirrels, California ground squirrels live in burrows which they excavate themselves. Some burrows are occupied communally but each individual squirrel has its own entrance. They commonly feed on seeds, such as oats, but also eat insects such as crickets and grasshoppers as well as various fruits.

2. It is rather common in the maritime Pacific Northwest, Frog Pelt Lichen (Peltigera neopolydactyla) can range in color from bluish green to olive brown. It is found growing on both rocks and dead wood, in shady, open forests at varying altitudes. A large, loosely appressed leaf lichen, the lobes are broad, 10-25 mm wide, and the upper surface hairless. Often bearing brownish, tooth-like fruiting bodies on raised lobes along the lobe margins, the lower surface is whitish, cottony, bearing low, broad, brownish or blackish veins and long, slender holdfasts (rhizines).

3. Trillium (sometimes called Wakerobin) is a genus of perennial flowering plants native to temperate regions of North America. Growing from rhizomes, they produce scapes (similar to a stem) which are erect and straight in most species but lack true, above ground leaves. Three large photosynthetic bracts (modified leaves) are arranged in a whorl about the scape. The flower has three green or reddish sepals and usually three petals in shades of red, purple, pink, white, yellow, or green.

4. Rough-skinned Newts are amphibious and are often seen moving to breeding sites during the breeding season. Migration to and from breeding sites varies among populations. Some newts spend the dry summer in moist habitats under woody debris, rocks, or animal burrows with adults emerging after the fall rains. In some populations, adults remain in the ponds and lakes throughout the summer and migrate back onto land in the fall when the rain starts. Often they will form large aggregates of thousands of newts in the water.

Poisonous skin secretions containing the powerful neurotoxin tetrodotoxin repel most predators. The poison is widespread throughout the skin, muscles, and blood, and can cause death in many animals, including humans, if eaten in sufficient quantity. Populations in Crater Lake have been shown to lack this neurotoxin. In most locations the Common Gartersnake, Thamnophis sirtalis, is the only predator of the newt.

5. The infamous banana slug is the common name for three North American species of terrestrial slug in the genus Ariolimax. These slugs are often yellow in color and are sometimes spotted with brown, like a ripe banana. These shell-less mollusks are detritivores or decomposers. They process leaves, animal droppings, moss, and dead plant material, and then recycle them into soil humus.

SCORING:
5 points: You must be a nature docent!
4 points: You are at home on the coast.
3 points: You think the coastal forest is beautiful, but would never spend the summer here.
2 points: You guessed randomly, right?
1 or 0 points: You’d really rather stay indoors.
