Massive rivers and kettles of raptors are migrating over the Texas A&M University-Kingsville campus. Tens of thousands of birds swirling like black clouds. Swainson’s hawks, broadwings, black vultures and other unknowns are mixed in the groups. One of the most incredible migratory spectacles I’ve ever seen. They are headed down the raptor river, a corridor that passes along the east coast of Mexico, funneling migratory raptors and many other species down into Central and South America. The groups of raptors I saw had moved a mile or two within fifteen minutes. They circled slowly heading towards the border of Mexico to the south. They will all move between the Sierra Madre Oriental and Gulf of Mexico after they hit the border, crossing through the states of Tamaulipas, San Luis Potosi, and Veracruz. Some will stop in Mexico’s Yucatan Peninsula, while others may continue as far as Bolivia.
