General

Philadelphia Vireo: Medium-sized vireo with olive-green upperparts and yellow-washed to yellow underparts. Head has a gray cap, dark eyes, and white-bordered black eye-line. Wings are olive-green with very faint wing-bars. Undertail coverts yellow. Sexes are similar.

Range and Habitat

Philadelphia Vireo: Breeds in southern Canada and northernmost U.S. Winters in the tropics. Preferred habitats include open second-growth woodlands, old clearings, burned-over areas, and thickets along streams and lakes.

Breeding and Nesting

Philadelphia Vireo: Three to five white eggs with brown and black speckles at larger end are laid in a nest made of grass, moss, lichens, and plant down, and hung by spider silk and insect webbing. Incubation ranges from 12 to 14 days and is carried out by both parents.

Foraging and Feeding

Philadelphia Vireo: Eats mostly insects, some fruits, and berries. Forages slow and deliberately in low to mid-level vegetation, often hanging upside down to pick off insects; sometimes forages while hovering.

Vocalization

Philadelphia Vireo: Song is a high, drawn-out "cherrie-o-witt, cheree, siss-a-wit, tee-o", similar to song of Red-eyed Vireo, but thinner, higher-pitched, and slower. Call is a low, nasal "rreh."

Similar Species

Philadelphia Vireo: Tennessee Warbler has a slender, pointed bill, brighter upperparts, white undertail coverts, indistinct wing-bar, and short tail. Warbling Vireo has olive-gray upperparts and head, pale lores, and lacks wing-bars.

4 and 6 letter alpha codesX

The four letter common name alpha code is is derived from the first two letters of the common first name and the first two letters of common last name. The six letter species name alpha code is derived from the first three letters of the scientific name (genus) and the first three letters of the scientific name (species). See (1) below for the rules used to create the codes..

Four-letter (for English common names) and six-letter (for scientific names) species alpha codes were developed by Pyle and DeSante (2003, North American Bird-Bander 28:64-79) to reflect A.O.U. taxonomy and nomenclature (A.O.U. 1998) as modified by Supplements 42 (Auk 117:847-858, 2000) and 43 (Auk 119:897-906, 2002). The list has been updated by Pyle and DeSante to reflect changes reported by the A.O.U from 2003 through 2006.

ITIS CodesX

The Integrated Taxonomic Information System (ITIS) was established in the mid-1990�s as a cooperative project among several federal agencies to improve and expand upon taxonomic data (known as the NODC Taxonomic Code) maintained by the National Oceanographic Data Center (NODC), National Oceanic and Atmospheric Administration (NOAA).

To find the ITIS page for a bird species go to the ITIS web site advanced search and report page at http://www.itis.gov/advanced_search.html. You can enter the TSN or the common name of the bird. It will return the ITIS page for that bird. Another way to obtain the ITIS page is to use the Google search engine. Enter the string ITIS followed by the taxonomic ID, for example "ITIS 178041" will return the page for the Allen's Hummingbird.
