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. This is believed because of the long days of flying in migration the thyroid gland sends out more T 4 which help the body cope with the longer journey.
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 ...
