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."

feeding grounds in the arctic to winter breeding areas
in Baja. Whaling almost wiped out gray whales and by

banned. The gray whale recovered and was removed
from the endangered species list in 1994."

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.
