NOTE: The forms of the Snow Goose are often referred to as "phases"; i.e. "I saw a blue phase Snow Goose". The definition of phase: a particular appearance or state in a regularly recurring cycle of changes. A Snow Goose does not change forms, however - it is either blue or white and will remain that way throughout its life. Stable forms such as in this species, or the Rough-legged Hawk, are correctly termed "morphs". Morph means: "Each of several variant forms of an animal or plant."
Ohio lies between major flyways for the Snow Goose and we don't get very many. Singles or small flocks are the rule, with occasional exceptions. The exception of all exceptions occurred on October 25, 1952 in Mahoning County. On that date, stunned observers tallied massive flocks totalling some 150,000 birds within a two hour period.
