Information, images and range maps on over 1,000 birds of North America, including sub-species, vagrants, introduced birds and possibilities


Species: The Bullock's Oriole (Icterus bullockii) is the second sub-species member of the Northern Oriole. It is found in the central USA northern states and up into southwestern Canada. Similar to other orioles, the Bullock's Oriole weaves its nest into the shape of hanging baskets. These birds are attracted to birdfeeders that entice them with fruits, jellies and nectar-type juices.

Distinctions: Sexually dimorphic, the male has a black crown and eyeline, black wings and tail feathers, large area of white coverts on wings, strong orange supercilium, back and body. The female has a light orange body, yellowish supercilium and whitish flanks and underbody, some white wing edging and black wings. Juveniles appear more like the females with maybe slightly brown coloured wings.

Voice: Musical whistles, some similarity to the Northern Oriole.

Nesting: Four to five whitish to whitish-grey eggs, with squiggles of brown and black lines. Nest built from grass, plant fibre, tree bark and string, woven into the shape of a basket and attached to branches high up in the crown of trees.

References to Other Bird Sites:

Avibase - the world bird database This site provides the user with a complete list of bird species, broken down per country, or in the example of the US or Canada, per state and province. Here, bird species names are available in other languages, a great asset to be used as a translation of foreign bird names.

ABA - American Birding Association This site represents an organization that maintains official records of all birds species that have been proven to have been seen inside the perimeters of the North American Continent and the surrounding bodies of water. Regular revised versions are posted to keep the bird list current at all times. This is the list used by all serious birders over their lifetime. You may be aware of the movie called the "Big Year". It was with this list that all the competing birders used in an attempt to set a new record as to how many bird species that could be seen by an individual birder in one calendar year.

I hope you will take advantage of these suggested websites. I have used each of them, in one way or another, throughout the years in my quest to better identify and understand our fine feathered friends.
