Why Don't Ruby-throated Hummingbirds Visit Ken's Garden in Winter?

What could be a testable hypothesis that Ken could make to explain the winter absence of the hummingbirds?

A. Where do ruby-throated hummingbirds go in the winter?

B. Do ruby-throated hummingbirds like cold weather?

C. Ruby-throated hummingbirds do not like being cold.

D. Ruby-throated hummingbirds hibernate during the winter.

Answer: Ruby-throated hummingbirds hibernate during the winter.

Ken enjoys bird watching and notices that every summer, he sees many ruby-throated hummingbirds in his garden. However, during the winter, he never sees any ruby-throated hummingbirds. To explain this winter absence, Ken could make a testable hypothesis that ruby-throated hummingbirds hibernate during the winter.

Hibernation is a strategy used by some animals to survive the winter months when food is scarce and temperatures are cold. By hibernating, animals can conserve energy and avoid harsh winter conditions. If the hummingbirds are not seen in the winter, it is possible that they migrate to a warmer location or hibernate to survive the winter months.

By hypothesizing that ruby-throated hummingbirds hibernate during the winter, Ken can conduct further research to test this hypothesis. He can observe other bird species in his garden during the winter, gather information about hummingbird behavior in colder months, or consult with experts in bird migration and hibernation.
