BEWICK’S SWAN RE­SEARCH

The Field - - News -

Re­searchers from around the world are meet­ing in Es­to­nia from 16-19 Oc­to­ber to dis­cuss the plight of the Bewick’s swan. The pop­u­la­tion fell by 40% be­tween 1995 and 2010.

The Wild­fowl & Wet­land Trust (WWT) has com­pared the body weight of swans it has caught over 50 years to see whether in­ten­si­fi­ca­tion in farm­ing might have led to food short­ages. “There’s no ev­i­dence that the swans are any­thing other than well fed while they’re here,” said WWT’S Dr Kevin Wood.

Re­searchers are look­ing at whether poi­son­ing, col­li­sions, habi­tat loss or il­le­gal hunt­ing are re­spon­si­ble for the de­cline.
