The study started in the spring of 1950 with 2 male and 4 female pilgrim geese which were mated together in two breeding pens. [15] The geese were bred progressively for 5 years and by 1954, there were 16 breeding pens each with 1 gander and 5 females. [15] All the geese were trap-nested 7 days a week for the duration of the laying season.
Canada geese leave the winter grounds more quickly than the summer grounds. Elevated thyroid hormones, such as T 3 and T 4, have been measured in geese just after a big migration.

[3] [5] As most domestic geese display little sexual dimorphism, sexing is based primarily on physical characteristics and behaviour. Males are typically taller and larger than females, and have longer ...

Snow geese are visitors to the British Isles where they are seen regularly among flocks of brant, barnacle goose, and greater white-fronted goose. There is also a feral population in Scotland from which many vagrant birds in Britain seem to derive. Around 2015, a small group of 3–5 snow geese landed on the north shore of O'ahu. They were seen ...
