Audubon's Oriole
Icterus graduacauda
The Audubon's Oriole (Icterus graduacauda) is essentially a Mexican species, which reaches extreme south Texas at the northern edge of its range. In Mexico, it may be found as far south as Oaxaca. I would never describe it is "common" in south Texas, but it is regularly encountered, especially in parts of Starr and Hidalgo Counties. The adult shown in the first three shots here was near Edinburg, Hidalgo Co., Texas in December, 2005. The photos were taken with a Canon EOS 1D Mark II and an EF 600mm F/4 L IS lens. In the first and third shot the bird has a sunflower seed in its bill.
The Audubon's Oriole shown here was near Rio Grande City, Starr Co., Texas, in December, 2007. This shot was taken with a Canon EOS 1D Mark III and EF 600mm F/4 L IS lens and 1.4X extender.
The next three shots of Audubon's Oriole show an immature male in Starr Co., Texas, in February, 1998. These shotswere taken on Fuji Velvia film with a Canon T-90.
