Our Avian Fellow-Traveler, the House Sparrow

By Ted. R. Anderson

The House Sparrow originally inhabited a broad geographic region stretching across Europe and North Africa and throughout most of Asia except mainland China. It lived in close association with people in both rural and urban communities and is now often referred to as an “obligate commensal” of human beings, meaning that it is dependent on its human neighbors.

When large numbers of people fled Europe in the mid-19th century to live on other continents, many missed their familiar avian neighbors, including the House Sparrow. In the mid-1800s, 100 sparrows were brought to the United States from England aboard the Europa and released in Central Park. With the help of subsequent introductions, the species spread across the continent, making their way to the Pacific coast by 1915. Similar introductions followed in Australia, Argentina and South Africa. Range expansions increased widely from each of these sites so that today the House Sparrow is widely distributed on every continent except Antarctica.

The House Sparrow is not common on the the Samarkand campus, but a lone male does spend much of each day repeatedly chirping near the entrance to our Smith Health Center, hoping, no doubt, to attract a female to his chosen nest site. My favorite place for sparrow-watching, however, is Renaud’s. Carol and I each order one of their fabulous pastries and a cup of coffee and sit in the outdoor patio. There I watch the sparrows hop around under the
tables picking up crumbs that fall to the ground as patrons eat their pastries. Clearly sparrows have good taste!

Celebrating California Oaks

Californians love to brag about their trees. We will tell you that we have the tallest, most massive and the oldest trees in the world – the coast redwood, the Sequoia redwood growing in the midSierra and the bristlecone pine which is found in a small area of the White Mountains east of the Sierra.


In my view, we should save our bragging rights for our native oaks – the 20 species (40 if you count the hybrids). some of which only grow in our state. I give my vote to our coastal live oak. This evergreen oak is only found along the coast from Mendocino County to Baja California. The nutritious acorn was the staple food for the Chumash. The women ground the acorns in their stone mortars and rinsed out the bitter tannins in running water. (Now that I’ve found a source of acorn flour, I’m going to try my hand at baking acorn bread).


The coast live oak is the commonest tree species on our campus with three individuals distinguished by their size. One tree, 50 feet wide, spreads across the Life Center courtyard with a luxuriant canopy of small leaves; a second is located in the large lawn below Westview and Northview; and the third, the largest, is next to the Rose Garden with an 80-foot-wide canopy and a stout trunk measuring ten and half feet in circumference. Most often, the oaks are sprouted from an acorn buried by a scrub jay and then forgotten about.


Thank you, Jesus and Pedro for measuring the circumference of the three largest oaks!
