This is the second Black-whiskered Vireo that I've seen on a Texas trip, the first being back in April 2006 at Smith Oaks in High Island. That was then about the 25th state record and others have occurred since, sometimes with several individuals in a spring. The burning question is which subspecies is involved - the Florida race V. a. barbatulus or the northern Caribbean subspecies V. a. bonairensis ? The latter is, apparently, notably longer billed than the Florida race and has occurred as a vagrant in Florida and Louisiana.
Black-whiskered Vireo - Sabine Woods, TOS Sanctuary, Jefferson County, TX. April 18th, 2012. Some of our group saw the same individual on April 21st when we returned to search for the Tropical Mockingbird featured in the previous post.
