Interesting Facts

 The Bay-breasted Warbler is closely related to the Blackpoll Warbler, and hybrids between the two species are known. They are also known to hybridize with Yellow-rumped and Blackburnian warblers.

 In contrast to the more stable populations of other warblers, their numbers go up and down depending on outbreaks of the spruce budworm. They are abundant during infestations, but decline or even disappear from some areas a few years later.

 Eighty-two percent of the global population of Bay-breasted Warbler nests in the boreal forest of North America.

 A group of warblers has many collective nouns, including a "bouquet", "confusion", "fall", and "wrench" of warblers.

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.

Flight Pattern

Weak flight on rapidly beating wings.

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.
