In Kanes' own words:
"Most of the birds I catch are in the water - so am on my hands/knees when catching - however some birds do wander out of the water and will feed at your feet. They seem to be more confident when the weather gets cold and natural food dries up - I've found November and December to be my most productive months. Also they seem to be more confident when larger wildfowl such as Mute Swan / Canada Goose are surrounding them."
Birds are aged on leg colour (adults have bright yellow, orange or even red on the side of the leg, juveniles have dull legs with the sides grey gradually becoming yellow/orange), breast colour (adults have a black breast and juveniles have white streaks on the breast) iris colour (reddish in adults and brownish in juveniles) and the size of the frontal shield (smaller in juveniles).
