The martins have returned to the Snake River Colony in Pine City, MN!  Last year was the first year for this site; it hosted three SY (second-year; hatched the previous year) pairs.  Two of the pairs successfully fledged four young each.  The third pair's nest was infested with Blowflies and all of the nestlings died.  An ASY (after second-year; an adult) male and female have returned.  This year, I hope to have at least five pair at this second year colony.
