Garden Warbler: Large, plump warbler with brown upperparts that become more grey-brown towards the end of the breeding season. Underparts are buff. There is a faint suggestion of a pale eyebrow and a small patch of grey on the side of the neck. Grey bill is thick and short, legs and feet are grey. Sexes are similar. Juvenile is more olive.

Range and Habitat

Garden Warbler: Common in Wales, England and southern Scotland; in Ireland and northern Scotland it is scarce. Found in mixed and deciduous forests, woodland edges, clearings, and hedgerows. Spends much of its time skulking in undergrowth and shrubs. Spends the winter in southern and central Africa.

Breeding and Nesting

Garden Warbler: Three to five white to buff eggs with grey or purple-brown spots are laid in a cup-shaped nest of grass, twigs and leaves built low in a small tree or bush. Both sexes incubate the eggs for 11 to 13 days, chicks fledge 9 to 12 days later. They are dependent for another 10 to 14 days.

Foraging and Feeding

Garden Warbler: Feeds primarily on invertebrates, such as beetles, spiders, caterpillars, aphids, flies and worms. In the fall eats fruit and berries. Forages in trees and undergrowth.


Garden Warbler: Alarm call is a harsh "tacc, tacc, tacc," song is a repetitive, rapid series of musical phrases.

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.


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 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.
