First Social Flycatcher in the US?

This week I visited The Research Museum at the Acopian Center for Ornithology at Muhlenberg College in Allentown, Pennsylvania. Their bird collection was in storage for many years, but in going through and curating their collection, they found this Social Flycatcher, collected in Brownsville, Texas in February 1887. This should represent the first Social Flycatcher record north of Mexico. Unfortunately there isn't a lot of data associated with some of these old specimens, but the record has been submitted to the Texas Bird Records Committee.
