January 13: Grenadier Pond in
High Park; on this unusually warm January day squirrels,
Canadian geese, wild ducks could be seen everywhere throughout the park

January 20 (a week later): Grenadier Pond froze, causing some confusion

January 20: it was -10 Celsius, but sunny and calm

January 21: frozen Grenadier Pond; skating started; no squirrels - probably went into hibernation; wild ducks and
Canadian geese moved couple hundred meters southbound to Lake Ontario; or they flew South?
