As mid June arrives and the longest days of the year are upon us here in western Massachusetts breeding activity rapidly reaches its peak.  Loads of species are on nest, feeding nestlings or feeding nestlings.  The next few weeks will bring more of the same as the next generation of many species head out into the big (and at times cruel) world.  A highlight for me today was seeing a Cerulean Warbler nest at Skinner SP being tended by two males and a female (cooperative breeding with this species is extremely rare).
