Behavior of bird: |
At the initial sighting, this bird was drinking from a small fountain that is on the rail of the deck. At that point, I had a clear, unobstructed view from 10 feet away without binoculars. The bird was outdoors while I remained indoors. He was in company of a female Baltimore Oriole [Icterus galbula] that had bright orange underparts from chin to undertail coverts. Both birds then moved to a flowering Abutilon pictum that was about 4 feet from the fountain. There, they drank nectar from the orange, bell-shaped flowers. After approximately 3 minutes, the Bullock’s Oriole flew to a seen-better-days Magnolia grandiflora that hosts a mature Trumpet Creeper Campsis radicans. In the tree, he pecked holes in Trumpet Creeper flowers. After a couple of minutes, a different female oriole flew into the same tree. Her plumage was a paler orange, with a pale grayish belly. I never got an unobscured view of her, so I cannot speculate upon her species. The Bullock’s Oriole moved back to the Abutilon pictum
after about 5 minutes with the paler female.
For the next 5 or so minutes, both of those birds moved around in the
shrub, but they stayed mostly deep within foliage and a clear view was not
possible at that point. I did not see
any of the orioles leave, but at some point, I lost all from view. |
Description: |
The salient field marks are that the head, neck, and upper
breast are very bright orange. A extensive
blackish 'goatee' extended from under the chin to the edge of the
breast. His crown, nape, and back are black. An orange supercilium
extends from the bill to the nape, bordering a distinct black eye line that
extends to the nape. Below the eye
line the face is bright orange. Except
for the ‘goatee’, all underparts are bright
orange. The wings are blackish with a
large white patch. The inner rectrices are black while the outer ones are bright
orange. This bird is roughly 8 1/4 inches long, with a slender Icterid shape. The
eye is dark and the sharply pointed Icterid bill
grayish. |
Voice: |
not heard. |
Similar species: |
This bird
exhibited all of the field mark of an adult male Bullock’s
Oriole. While they can appear
similar to Baltimore Orioles in other plumages, the adult male shows the
black ‘goatee’ and eye line, large white patches on the wings while the adult
male Baltimore Oriole has a complete black hood

Previous experience with
this species: |
I have seen a few dozen adult Bullock’s Orioles while
birding out west over the years. I’ve also
seen 8-10 adult male Bullock’s Orioles in Louisiana, plus a number of females
or probable Bullock’s females. In the
early 1980s, I hosted an adult male Bullock’s for the better part of a
winter. |
