Canada geese landing at winter night

It was already dark at 16:40, Jan. 1, 2024. Lots of Canada geese flied in and landed on the shallow water at Park Rapids, Montreal, Canada. They were going to spend another winter night here.

Some of them have taken permanent residence in the northern states.

Yes. It's interesting. Some probably will live always in the south (USA). If this is true, Canada geese will differentiate eventually into 3 sub-species: southern (non-migratory), central (migratory), and northern (non-migratory).
