There is one major difference between the Black-whiskered Vireo and the Tropical Mockingbird both of which were both found on the same day at Sabine Woods. One species is known to be highly migratory while the other is not known to migrate at all. With a steady stream of oil tankers chugging from Campeche up to the Texas City, there is a ready conduit for transportation of nonmigratory Mexican species to the Texas coast. These could also include Double-toothed Kite, Yucatan Vireo and Greenish Elaenia, all accepted by TBRC for some reason. The bottom line is: If it feels good, count it! Dan Jones, Weslaco
