Birds in SpaceTrivia brain teasers have some element of trivia in them, but they are not just pure trivia questions.
When NASA was considering animals to experiment on in space, they picked birds, because of the low maintenance. Although NASA was aware that most birds require gravity to swallow and would not survive the weightlessness of space, they did manage to find two types of bird that would survive the trip.
Which birds were they?
AnswerDoves and Pigeons.
Since most birds swallow water by tilting their heads back and using gravity to let the water run down their throats, they would dehydrate in space. Doves and Pigeons are the only birds that can drink without tilting their heads back.
