At Bentsen Rio Grande there were a few of these "smudgy" Altamira Orioles that did not have teh defined black throat of most Altamiras. Some were saying that they were Audubon x Altamira hybrids - but I'm not sure?
Anyways I hope you enjoy the image.

Top shot Glen - I like the diagonal pose here, good exposure and fine detail. The yellow lichen complements the same tone of the bird and the 2 clumps of lighter toned lichen balances the composition nicely. Well executed!!
