vireo,

small, migratory songbird of the New World. Some species nest in the United States, but the majority are tropical. Vireos (also called greenlets) range from 4 to 6 1/2 in. (10.2–16.5 cm) in length; they are greenish above and white or yellowish below and have either stripes above or rings around the eyes. They search methodically through vegetation for insects. Vireos are known for their loud, persistent call and for their cup-shaped nest that is suspended in the fork of a tree limb. American vireos include the red-eyed, white-eyed, warbling, Philadelphia, yellow-throated, and blue-headed, or solitary, vireos. Vireos are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.

Those species that commonly breed in cooler, more northerly, mainly coniferous forests, such as Blue-headed Vireo, Winter Wren, Magnolia Warbler, Black-throated Green Warbler, Blackburnian Warbler, Canada Warbler, Dark-eyed Junco, and Purple Finch, were found in pine plantations, mixed pine-deciduous woods, and the hemlock-deciduous forests in the gorges and ravines of the Pierson Creek and Stebbins Run watersheds.
Unfortunately it hid its grey body, with a neat black cap and rusty undertail in thick gorse, leaving the vast majority frustrated, but keen-eyed observers then spotted a rare red eyed vireo just a few hundred yards away
