List three examples of stimuli that a bird responds to

Stimuli refer to a thing or event that arouses the energy or give reaction to something or to someone.
Now, let’s give 3 examples of stimuli that a bird responds to:
=>  Weather Condition – When something bad weather is coming, birds are flying to a different direction that’s away from the bad weather of typhoon.
=> temperature – Birds are not going to stay on a place with too cold and too hot temperature.
=> food availability – birds will always look for a place with abundant food. If there’s no longer food available  to the place they’re in, they’re going to transfer to another place.

Used to water and cool climates, probably not thick coated or fluffy. they most likely have thin coats and have to survive to find food. sorry if this wasn't the answer you were looking for..: )
