The Most


Stellar Jay


mart, gregarious


and handsome, the


Steller’s jay lives


year-round in the


western half of North America,


frequenting campgrounds,


picnic grounds and yards.


From a distance, the Steller’s,


which is related to the blue jay,


may look like just a dark crested


bird. A closer view reveals its


striking dark head and shoulders


contrasted with its deep blue


body and tail.


Jeff Black, a Department of


Wildlife professor at Humboldt


State University based in Arcata,


California, has been studying


Steller’s jays since 1998. These


brightly colored jays belong to the


corvid family, known to be among


the most intelligent in the avian


world. That, along with the birds’


sociable nature, makes it easy to


observe them.


“Here in Arcata, California,


jay pairs stake claim to our yards,


both front and back, and they stay


all day and all year,” Jeff says.


Researchers fit the birds with leg


bands, each with a different color


combination to identify them.


“Jay pairs readily come to bird


feeders, so we can see who’s who


and who they are hanging out with


or chasing off,” Jeff says.


To attract Steller’s to your own


feeder, offer peanuts, black oil


sunflower seeds, suet or fruit. Pine


and oak trees are alluring cover


S


THE FEED


and provide additional food and


nesting sites.


Steller’s are opportunistic birds,


eating any leftovers people may


leave behind, insects, berries,


nuts, bird eggs and even small


animals such as lizards. As winter


approaches, they hide food for later


retrieval, gathering nuts and seeds


in their throats and stuffing the


nourishment into nooks and other


hiding spots for later in the year.


These clever and social jays


communicate with other birds


in a variety of ways. Jeff says,


“They have dozens of call types


conveying different information.”


These include harsh rattles and


melodious notes.


“Steller’s jays also imitate calls


made by hawk species they live


with,” he says. In winter, they use


those calls to scare other birds


away from feeders so all the food


is left to them. Using their voices


in another way, they team up to


scold and chase away predators,


including the great horned owl, in a


group behavior that ornithologists


call mobbing.


Adults likely mate for life. They


engage in courtship feeding and


show off by throwing their crests


and vibrant blue feathers around.


During the breeding season, a


pair gathers pine needles, twigs,


grasses and mud to construct a


cup-shaped nest where the female


incubates up to six blue-green eggs


with dark brown spots.


FIRST CLASSIFIED


Steller’s jays are named after


German naturalist Georg


Steller. He first documented


them on an expedition to


an Alaskan island in 1741.


Steller’s are one


of my favorite birds


to watch. I love


their dusty blue


color against the


deep green pines


in the mountains


of New Mexico.”

BIRDS OF A


DIFFERENT FEATHER


These jays are found in


a variety of environments


from Alaska to Nicaragua.


There are many subspecies,


differing mainly in the pattern


of white or blue markings


on the head.


Attract bold and witty Steller’s jays to your


yard and experience their playful antics.
