Dear all,The questions asked on this forum often send me to check in HANZAB, a most wonderful resource. I've seen gulls behaving like this but not wondered about what they were doing, just guessing that it had something to do with food gathering. Turning to HANZAB, tells me that Silver Gulls will eat just about anything they can get their beaks on! About the foot work it says: "Foot-trembling in soft substrates to bring food to surface" then further - "foot paddling while floating, use feet to bring food to just below surface, then seize prey." So the beach foot-trembling would be to capture small crustaceans, I guess. Regards Shirley Shirley Cook Secretary/Treasurer Birds Australia (Northern NSW) |
