cold front draped across the country from Nevada to the Ottawa, Canada marked the southern boundary of moderate to heavy migration down into the midsection of the U.S. this morning. High pressure over the Southeastern U.S. also allowed birds to move south but migration densities were much more diffuse. Migration was also evident across the western U.S. all the way to the Pacific Coast. Birders along the aforementioned front this morning should be on the lookout for high densities of birds locally.
