Opossum in daylight. Watercolor and ink. Usually seen squished or flattened on roads and highways across the country, these nocturnal critters are...well they are still ugly in a cute kind of way. The Virginia opossum has more teeth than any other North American Mammal - 50, to be exact.
Gerbil family. Watercolor, pencil and ink. Gerbils, although nocturnal actually go through several cycles of activity each night. Gerbils need a nest box to feel secure."Thumping" is an interesting gerbil behavior. The gerbil will pound both hind legs on the ground when he is excited or stressed. Young gerbils tend to thump even when not stressed. If you have multiple gerbils, they will all join in on thumping behavior.
Green bottle fly. Gouache and ink on watercolor paper. For the Oklahoma Museum of Natural History. The name of the bottle fly derives from the shiny, metallic appearance of the fly.

Sunlit wolf. Watercolor and pencil. Immense power is concentrated in a wolf’s jaw. It has a crushing pressure of nearly 1,500 pounds per square inch (compared with around 750 for a large dog). A hungry wolf can eat 20 pounds of meat in a single meal, which is akin to a human eating one hundred hamburgers. The North American gray wolf population in 1600 was 2 million. Today the population in North America is approximately 65,000.
Rabbit. Watercolor, pencil and ink.
During warmer seasons, rabbits will eat weeds, grasses, clover, wildflowers, and flower and vegetable plants. When the weather turns cold, rabbits will munch on twigs, buds, bark, conifer needles, and any remaining green plants. When being chased, rabbits will run in zigzag formations to confuse, rather than outrun, their predators.
Squirrel. Watercolor, pencil and ink. Squirrels are fascinating creatures; they can leap ten times their body length. They can also turn their ankles 180 degrees to face any direction when climbing. They’ve got excellent vision, and they learn by swiftly copying other animals.
Nesting seabirds. Watercolor and pencil. Illustration for interpretive panels at Coquille Point-- Oregon Islands National Wildlife Refuge. From the panel: "Common murres crowd together by the thousands, while pigeon guillemots nest further apart in cavities. Colonies tend to be larger when food is abundant. Puffins, storm-petrels, and auklets use their beaks and feet to dig burrows in grassy slopes. Pigeon guillemots prefer rock crevices or holes. Brandt’s cormorants build nests of grass and seaweed on flat or gently sloping ledges, while pelagic cormorants build seaweed nests—glued together with guano— on narrow ledges."
Sandhill Crane. Watercolor and pencil. Cranes are among the oldest living birds on the planet. For the Muleshoe National Wildlife Refuge in North Texas. National Park Service. Did you ever wonder how cranes stay warm while standing for hours in near-freezing water? They can reduce the amount of blood that has to be warmed by constricting blood vessels in their feet.
Roadrunner for a day/night scene at Clark County Wetlands Park Nature Center in Las Vegas Nevada. Watercolor and pencil. Roadrunners are also called earth-cuckoos, chaparral cocks, snake killers and ground cuckoos. While they are generally solitary birds or are found in pairs, a flock of roadrunners can be called a marathon or race. Go figure.
Estuary. Watercolor and pencil. An estuary is created where freshwater from a river meets saltwater from the sea. Tides deliver fresh nutrients to the estuary twice a day.
Coquille home. Watercolor and pencil. This area has long been home to the Coquille Indians. A wealth of natural resources from the ocean, river, estuary and forest provided all they needed for food, shelter, clothing, tools and transportation.
Suburban cougar. Watercolor and pencil. Oregon Zoo. Cougars are shy and solitary creatures, typically going out of their way to avoid humans. But in recent years, the number of big cats showing up in backyards and city parks has grown.

Sketchbook rendering of a Sea Cucumber for the Oregon Zoo. Watercolor and pencil. 6" x 6".
Sea cucumbers do not have a brain. Their senses are also poorly developed. They breathe via their anus. They are able to modulate the shape of their body when needed so they can pass through tight spaces. In other words, they could become great politicians.
Field note sketchbook rendering of a Limpet for the Oregon Zoo. Watercolor and pencil. 6" x 6". At low tide, to avoid drying out, limpets trap some water inside their shells. They create their own tide pools right inside their shells.
Harbor seals. Watercolor and pencil. Illustration for interpretive panels at Coquille Point-- Oregon Islands National Wildlife Refuge. From the panel: "Harbor seals may be seen at haul-out sites with other sea mammals, such as Steller’s and California sea lions. Harbor seals are small with spotted gray fur. Unlike sea lions, harbor seals are “true seals”; they have stout, round bodies, no external ear flaps, and cannot rotate their flippers under their bodies."
Sketchbook rendering of a Kelp Crab for the Oregon Zoo. Watercolor and pencil. 6" x 6". Kelp crabs, as their name implies, are typically associated with species of kelp, and they are colored much like them. They are also common, especially younger individuals, in the low intertidal in beds of other algae and eelgrass.

Pacific Gray Whales. Watercolor and pencil. Illustration for interpretive panels at Coquille Point-- Oregon Islands National Wildlife Refuge. From the panel: "North Pacific gray whales migrate between summer
feeding grounds in the arctic to winter breeding areas
in Baja. Whaling almost wiped out gray whales and by
1970 the species was endangered. Soon after, Mexico
began protecting calving grounds and whaling was
banned. The gray whale recovered and was removed
from the endangered species list in 1994."
Field note sketchbook rendering of an Ochre Sea Star for species identifier panels at the Oregon Zoo. Watercolor and pencil. 6" x 6". Ochre Sea Stars are relatively large sea stars, with five arms and a rough surface. Most of them are either orange (ochre) or purple, quite a dramatic difference, and there is still no good way to explain this.

The China rockfish has a distinctive appearance, with a dark blue or black body crossed by a patchy but obvious yellow stripe and may be covered with small whitish or yellowish spots.

Carpenter ant. Gouache and ink on watercolor paper. For the Oklahoma Museum of Natural History. Carpenter ants are neat-freaks. Very hygienic, carpenter ants remove all deteriorated foods and deceased ants from their nests. They even create their own disinfectant. Now don't you feel bad for stepping on them?
Cockroach. Gouache. No, a cockroach cannot survive a nuclear blast. This is one of the most common myths to be quoted as a fact. The truth is that a cockroach can withstand 10 times more radiation than a person, but they would not survive a nuclear event. However, there are much easier ways of getting rid of them.
Mouse tail. Gouache. Mice can squeeze through tiny gaps. By flattening out their bodies, mice are able to squeeze through gaps as small as 6mm. That’s roughly the size of a pencil.
