Join Natural Areas field trip leaders in searching for the avian nesters which call the cool hemlock and yellow birch groves their home within the Blakeslee/Barrows preserve. The songs and call notes of the rare boreal nesters such as Yellow-bellied Sapsucker, Winter Wren, Hermit Thrush, Magnolia Warbler, Black-throated Green Warbler, Black and White Warbler and Dark-eyed Junco will help to define localities being used for rearing young.
