Steller’s Jay (Cyanocitta stelleri)

The Steller’s Jay (Cyanocitta stelleri) is the largest jay in North America measuring in at 12-13 inches. Like many humans, this bird knows it never hurts to have a few tricks up your sleeve. They have a few unique skills that might surprise you.

The Steller’s Jay is related to the Blue Jay but has a slimmer bill and longer legs. It is also the only western jay with a crest. The front part of this jay is black while the back, wings and tail are dark blue. This coloring helps the Steller’s Jay easily blend in with the evergreen forests of the mountainous West where it is typically found, although this bird is also known to frequent campgrounds, parks, and backyards.

This bird is very intelligent and opportunistic. Steller’s Jays usually travel in pairs or family groups. They have a complex social and communication system, with a variety of calls, postures and displays. For instance, a spread wing shows submission, and a raised crest might mean attack. Steller’s Jays may also mimic the screams of hawks and Golden Eagles. This bird feeds mainly on acorns and pine seeds, but will raid other bird’s nests for eggs and nestlings. They will also eat small reptiles, nuts, berries, fruits, and insects.  Curiously, these jays have distendable esophagi that they are able to use to carry acorns and nuts. These foods are often cached for the winter or saved for eating at a later time. What unique skills do you have up your sleeve?

Locals and visitors alike marvel at the iconic image of the Douglas-fir. Did you know this tree provides for much more than good pictures?

This tree is highly revered, not only for its beauty, but usefulness. It has  played an important role in the history of Oregon, as well as the United States. Impress your next visitors by sharing new knowledge about this interesting species.

Naming

Scottish physician Archibald Menzies first documented the tree on Vancouver Island in 1791. A rival botanist, David Douglas named the tree over 30 years later. 

David Douglas, a botanist who described the tree in 1825 was the first person able to grow this tree in England. 

Not a fir

The Douglas-fir is not what it seems and the scientific name gives a clue (Pseudo = false, tsuga = fir). It is not a fir, but an evergreen conifer that is part of the pine family.

This tree is very long lived and tall. It can reach 330 feet tall and have a life expectancy of 1,000 years. It grows taller and faster in the coastal rainforests where there is good drainage.

State Tree

More than a century later in 1939 the Douglas-fir was designated Oregon’s State tree in recognition of the significant role it has played in the state’s economic development.

Economics

In addition to being beloved by Oregonians, the Douglas-fir is well-known across the country. Today, Douglas-fir is the country’s top source of lumber and accounts for nearly half of the Christmas trees grown in the United States.

Utility

Douglas-fir was also extensively used by Native Americans for building, basketry, and medicinal purposes. The wood was used for railroad ties, and telephone and telegraph poles as the nation expanded west.

Keep an eye out for this important species next time you explore the Oregon Coast!

California sea lion (Zalophus californianus)

California sea lions are members of the “eared seal” family Otariidae. These pinnipeds live along the rocky Pacific Ocean coastlines of western North America.

They are very social animals and form groups of several hundred individuals onshore. In many areas they have become quite invasive and obnoxious. 

California sea lions are the most recognized pinniped species because they are commonly seen doing acrobatic tricks in shows at zoos and aquariums. While they are known for their intelligence and playfulness, these animals also quite athletic.

In the wild, the California sea lion swims up to 25 miles per hour, which is faster than any other sea lion or seal. This superb speed is related to how they use their front flippers.

Quick Diver

This animal is also an avid diver. When diving deep, California sea lions slow their heart rates to allow them to remain underwater for nearly 10 minutes before surfacing to breathe. This ability gives them an edge in the pursuit of the fish, squid, and shellfish that make up their primary diet.

California sea lions have color vision. They don’t see all colors, however, but are limited to blue-greens of the color spectrum.
