The parents are very protective so it is very difficult to get close. I'm thinking I will try again tomorrow with a zoom lens. We have had this pair of Canadians for several years. This is the first year that they have had more than one gosling survive. I "think" we have had 5 previous babies. The first two flew away after they were grown - presumably to find mates. The other three are still here although one of them flies away from time to time but always seems to come back.
