few weeks ago, we see two individuals brent goose (Branta bernicla ) Txingudi the Bay, particularly in Beltzenia (Hendaye) and Itzaberri (Plaiaundi). This is an accidental species, whose appearance is almost always related with leaks of seasoning. Probably the origin of these individuals is the wintering population of the Bay of Arcachon (France), where the species now exceeds 15,000 individuals. In Txingudi Marshes, usually settle isolated individuals or small groups within the subspecies Branta bernicla bernicla . Food requirements of the brent goose, based on foraging in meadows of sea silk ( Zostera sp) and other halophytes, found no positive response Txingudi Marshes.
Greetings.
