Birds of Panama - large bird photo gallery
The Yellow-faced Grassquit (Tiaris olivaceus) is a passerine bird from the Central American tropics and surrounding regions. This species feeds mainly on grass seeds, but also takes other seeds, berries and some insects. Food is typically plucked from the inflorescences directly, or gathered from the ground. Animal prey is hunted among foliage in a New World warbler-like fashion. For more details from Wikipedia about the Yellow Faced Grassquit please see this page here.
