Exciting new discovery.  Fish eating Goosanders weaned off fish for a diet of bread.  If only !!!.
Spot the Goosanders at Llandrindod Lake fighting over who gets the bread. Get within ten feet of one and experience the feeding habits at close range.  When they appear on your local river they may not, at first be too apprehensive at your approach.  Have a shotgun to ensure they don't get a second chance.
Eight or so drakes overwintering here with attendant females. At a location near you soon.
