Cornell:
“A bird true to its name, the Pine Warbler is common in many eastern pine forests and is rarely seen away from pines. These yellowish warblers are hard to spot as they move along high branches to prod clumps of needles with their sturdy bills. If you don’t see them, listen for their steady, musical trill, which sounds very like a Chipping Sparrow or Dark-eyed Junco, which are also common piney-woods sounds through much of the year.”
