Range and Habitat

Sedge Warbler: Summer breeder found throughout the UK & Ireland. Range extends east across much of Europe to western Siberia. Birds can be seen from spring until autumn when they leave for sub-Saharan Africa. Prefered habitat is comprised of wetland areas, particularly those with reedbeds.

Breeding and Nesting

Sedge Warbler: Monogamous. Nest is a cup on the ground, often in reedbeds near water, but may be well-hidden in bushes away from water. Female builds nest and is primarily responsible for incubating the five to six eggs for 13 to 15 days, although the male helps. Both parents care for young.

Foraging and Feeding

Sedge Warbler: Usually feeds at dusk or dawn in low, dense vegetation, like reeds or rushes. Mainly feeds on insects like mayflies, dragonflies, grasshoppers, moths and beetles. In autumn and winter it will eat plant material like buds and berries.


Sedge Warbler: Very complex song that combines both pleasant as well as harsh notes - "chit-chit-tuk-tuk-tuk-chit-ter-we-terwee-tit-tit-twee-twee-tit-it-it-it-cherwee." Call is a sharp "tuk" or a soft "churr."

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.
