Bay-breasted Warbler

Bay-breasted Warbler: Medium-sized warbler with dark-streaked gray upperparts and buff underparts with chestnut-brown patches on the chin, throat, breast and flanks. The head has a dark brown crown and black mask. Wings are black with two white bars. It is one of the largest warblers.

● Song: "tees teesi teesi teesi teesi teesi"

● Foraging & Feeding: Bay-breasted Warbler: Eats caterpillars, beetles, flies, moths, mayflies, ants, lacewings, and canker worms. Generally gleans prey from mid-level, inner part of conifers, particularly on lichen-covered limbs with little foliage, but readily forages at other heights within the tree and in broad-leaved foliage.

● Breeding & nesting: Bay-breasted Warbler: Four to six brown or purple marked, white, green or blue eggs are laid in a loosely built, hair-lined nest made of twigs, grass, and needles set in a conifer as much as 50 feet above the ground. Incubation ranges from 12 to 13 days and is carried out by the female.

● Similar species: Bay-breasted Warbler: Chestnut-sided Warbler has yellow crown and white throat. In winter, Blackpoll Warbler has yellow legs, white undertail coverts, and more streaks on breast. Pine Warbler lacks black streaks on the back and has yellow on throat and breast.

4 and 6 letter alpha codes

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.
