Current Research Projects:

The Bird Phenology Program is currently looking at Barn Swallow data to explore it’s quality and characteristics. After this is assessed, the BPP will analyze more specific information with this data set such as the cycle of arrival dates over time, the association of spring temperatures, and latitudes and longitudes throughout North America.
