May BOTM: Orioles

 

 . . . they chatter like blackbirds; the fire bursts forth on their backs when they lift their wings.

- Thoreau, The Journal, 1852

We have two oriole species which breed in California in the summer, and both can be attracted to feeders. Hooded Orioles and Bullock's Orioles arrive beginning in late March and depart between August and September. They will enjoy the same nectar solution used to feed hummingbirds, although if putting out a dedicated feeder for orioles, we recommend using a slightly less concentrated nectar solution of a 6-to-1 water-to-sugar ratio (we recommend 4-to-1 for hummingbirds).
      Orioles also enjoy jelly; most normal grape jellies work fine, or use our special BirdBerry Jelly, which uses a mix of grape and blackberry and comes in an easy to use squeeze bottle. Orioles may also eat mealworms (particularly attractive when feeding young birds) or fruit (grapes and others), but sugar water and jelly appear to be the clear favorites in our area. While orioles can use some hummingbird feeders, a specialty oriole feeder such as the one shown to right has some advantages: wider ports to accommodate their beaks, larger size perches, and jelly-holding cups in the lid in addition to the main sugar water basin.

Hooded Oriole Nest

  • Hooded Orioles winter in Mexico, arriving in Northern California from late March. Their Bay Area breeding habitat is entirely suburban.
  • Hooded Orioles have undertaken a dramatic northward expansion in California: their summer range was limited to southern California until the 1930s
  • This expansion was dependent on the planting of fan palms in residential areas and parks; palm fibers are the essential building material for their nests, and the palms are generally themselves the nest sites. Oriole's preferred palm is the California fan palm (Washingtonia filifera), native to southern California, but they will occasionally use other non-native palms as nest sites
  • Hooded Orioles are among the most interesting of nest builders, actually sewing filaments through leaves to achieve a nest which hangs like a hammock. Photo to left by Neil Solomon.

Some hummingbird feeders, such as this feeder by First Nature, have feeding ports that are wide enough for orioles to access. Some do not.

Bullock's Oriole: black cap and eyeline

  • Oriole nests collected in the late 1800s, before the age of the automobile, were made almost exclusively of horsehair. Now they use a combination of plant fibers and a wide range of artificial materials, readily employing fishing line, string, yarn, and plastic Easter grass. Male Bullock's Oriole
  • Bullock's Orioles nest in a variety of trees, including native oaks and willows, but the distribution of breeding orioles in Marin seems to have increased significantly as a result of planted eucalyptus groves, which supply both nesting sites and nectar (Marin County Breeding Bird Atlas).
  • Nesting Bullock's Orioles are most often encountered in riparian (streamside) areas.
  • Most Bullock’s Orioles spend their winters in central and southern Mexico, with a few staying along the coast of southern California.
  • The Baltimore Oriole, found in the east, and the western Bullock’s Oriole were once considered to be the same species under the name Northern Oriole. While they do inter-breed in areas where their ranges overlap, genetic studies have shown them to be two distinct species.
  • Orioles' closest relatives include blackbirds, meadowlarks, grackles, and cowbirds.

Oriole IDFemale Bullock's Oriole

Male Hooded Orioles are easily differentiated from male Bullock's Orioles: Hoodeds have an golden body with a black throat, wings, and tail, while Bullock's have a black eyeline, cap, and central tail feathers. Females are a little more difficult, but remember that Hoodeds have longer, slightly downcurved beaks in all plumages. Female Bullock's (pictured) have a very white belly in contrast to the dull yellow of the Female Hoodeds.
