I’m celebrating 30 years of writing “Feathered Friends” by looking back at some older columns. This week I’ve combined columns first written in 2006 and 2016 into a new feature focused on orioles.

In May of 2006, I made my second trip to the Utah, also known as the “Beehive State.” I’d made my first visit in October of 2003. The contrast between the two visits could not have been more extreme. My 2003 visit took place when Salt Lake City and the surrounding area had been in the grip of an extensive drought. Mountainsides looked dull brown and gray and reservoirs had almost dried up. When I returned in the spring of 2006, green greeted me everywhere I looked. The drought had broken and Salt Lake City didn’t look quite so bleak.

I saw many species of blackbirds and their close kin, including Brewer’s blackbird, Western meadowlark, yellow-headed blackbird, red-winged blackbird, common grackle and Bullock’s oriole. Most of these birds were extremely abundant and surprisingly tame. I didn’t know it at the time, but birds in the western United States are generally tamer and more approachable than birds in the eastern half of the country. There are various factors to explain this difference in behavior, including the rugged terrain and the fact that many western areas have only been settled for a couple of centuries compared to nearly 500 years of settlement in the eastern United States.

The Bullock’s oriole proved one of the tamest of all the new birds that I saw on my trip. Trees and shrubs bordering walking and biking trails along the Jordan River popped with small flocks of these colorful, noisy orioles. As my visit took place in May, it’s quite possible these orioles comprised a “fallout” of migrants so occupied with feeding after a long flight that my presence didn’t rank high in their priorities.

Regardless, I found the Bullock’s orioles gregarious and sometimes comical as they chirped from willows and other shrubs close to the river. Close to home, I count myself lucky to see a single Baltimore oriole at a time. Even when I do succeed in sighting one, the Baltimore oriole is often high in the treetops and not easily observed. Such fleeting and infrequent observations of Baltimore orioles are a sharp contrast to seeing flocks of the equally colorful Bullock’s oriole in Utah.

The bird is named for William Bullock, an English traveler, collector of natural history specimens and a bit of a showman. In 1822 and 1827, he visited Mexico, which is perhaps where he first encountered the oriole named for him. He also visited the United States in 1827. He established some museums, including one he called Piccadilly Egyptian Hall, that featured some unusual artifacts. Among the collections was Napoleon’s carriage that had been captured at the Battle of Waterloo.

Bullock’s oriole and Baltimore oriole were, for a time, considered a single species. The American Ornithologists’ Union lumped the two birds together from 1973 to 1995 as a species known as the “Northern oriole.” It’s easy to see similarities. Both the Bullock’s oriole and the Baltimore oriole sport vibrant orange plumage accented by white and black in the case of Bullock’s oriole and black in the case of the Baltimore oriole.

Despite their bright plumage , they are related to blackbirds such as red-winged blackbird and common grackles. Icterids, or New World blackbirds, make up a family known as the icteridae that consists of small to medium-sized songbirds. In his book titled “Birds of Forest, Yard, and Thicket,” John Eastman notes that there are 26 species in the genus, eight of which nest in the United States. In the eastern United States, there are only two orioles — the Baltimore oriole and its smaller relative, the orchard oriole. The western half of the nation is home to a half dozen orioles, including Bullock’s oriole, Scott’s oriole, Audubon’s oriole, hooded oriole and Altamira oriole.

In Northeast Tennessee, tall trees are an essential part of the Baltimore oriole’s favored habitat. Baltimore orioles are well-known for their colorful appearance, but their fame also rests with a sack-like nest that Eastman describes as a “durable marvel of tight-woven plant fibers” in his informational book. The Bullock’s oriole is also known for building these impressive sack nests.

Orioles are present in the United States from April to October, generally retreating to the American tropics for the cold months of winter. There they may live on plantations that produce such much-coveted crops as bananas, coffee and cacao, which is the essential ingredient for chocolate.

Those who are fortunate enough to have a Bullock’s oriole or a Baltimore oriole as a neighbor should know that it isn’t only the bright coloration and elaborate nest building that recommend these birds. They’re also some of the few birds willing to eat the hairy tent caterpillars that are often a blight on the landscape. Back in the late 1990s, I observed a male Baltimore oriole visiting a large caterpillar tent in the branches of a cherry tree. The bird methodically plucked the caterpillars from the silken tent, eating them one after the other. While many birds avoid some of the spiny and hairy caterpillars, these two orioles actively seek them out and do a great service of reducing the damage these hungry caterpillars can inflict on the environment. They will also apparently eat Gypsy moth caterpillars and fall webworms.

On a handful of occasions, Bullock’s orioles have strayed into the Volunteer State. Some documented recent vagrant Bullock’s oriole visits have occurred near Nashville and Chattanooga.

I will always count myself fortunate to have been in the right place at the right time to enjoy my “fallout” of Bullock’s oriole near the Jordan River in 2003 during my Utah trip. The moment remains one of my most memorable birding experiences.
