CF2C2855-001Spring has truly arrived and bird migration is in full swing with many breeding birds returning to local nesting sites.  Among the sparrows, the Savannah Sparrows are being seen at Crane Wildlife Management Area on Rt. 151.  From spring to early summer, males perch atop prominent shrubs, tall weeds, or fence posts in agricultural fields, meadows, and salt marshes.  They sing their distinctive songs to stake out their territory.  The Savannah Sparrow is a small sparrow with dark streaking, gray-brown upperparts, white underparts, brown streaks on breast and sides, and distinctive yellow eyebrows.
