Conservation Description


The Balearic Shearwater has a very small breeding range that is limited to the Balearic Islands, Spain. Non-breeding birds range widely in the central and western parts of the Mediterranean Sea, and in the northeastern Atlantic Ocean. It breeds in caves on cliffs and small islands, and forages on the open ocean, often in the vicinity of fishing boats. This shearwater has an estimated population of anywhere from 10,000 to 30,000 individuals and is evaluated as critically endangered on the IUCN Red List due to an extremely sharp decline in its numbers. The reasons for its decrease are numerous and include predation by cats, rats, and genets on its breeding grounds, disturbance caused by urbanization near breeding areas, mortality from drowning after taking bait on fish hooks set out by long line fishing boats, and a reduction in the numbers of small pelagic fish that are an important food source.

SUMMARY

Overview

Balearic Shearwater: Medium-sized seabird with rather pointed wings and slender bill. Dark brown above, dark brown and white on underparts, and white wing linings. Light eye ring and grey bill. In flight, has heavy looking belly and toes that project beyond short tail. Critically endangered.


Range and Habitat

Balearic Shearwater: Summer visitor to areas of south England, western Wales, and the east coast from July through September. Migrates to the south of France and Balearic islands for breeding in summer. Can be seen plunge-diving for food or resting on the surface of the water in coastal areas.

SONGS AND CALLS

Voice Text

Generally silent, at nesting colonies makes coughing and "aii-ah-eech" calls.

INTERESTING FACTS

  • The Balearic Shearwater was long considered to be a subspecies of the Manx Shearwater.
  • They nest in burrows which are only visited at night to avoid predation by large gulls.
  • While silent at sea, breeding colonies are filled with loud coughing and cackling calls at night.
  • A group of shearwaters are collectively known as an "improbability" of shearwaters.

BIRDS AND BIRDING

.
PelagicX
The pelagic is a type of bird whose habitat is on the open ocean rather than in a coastal region or on inland bodies of water (lakes, rivers). An example of a pelagic bird is the blacklegged kittiwake.
UnderpartsX

Belly, undertail coverts, chest, flanks, and foreneck.

BellyX
The ventral part of the bird, or the area between the flanks on each side and the crissum and breast. Flight muscles are located between the belly and the breast.
Eye ringX
The circle around the eye formed of feathers that are a different color from the rest of the face.
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.
