No, speed is not a vector. Velocity is a vector (speed in a direction). Since speed does not need a direction to describe it, it is irrelevant which direction the bird is flying. The only factors are distance and time.

Can a car driving backwards have a positive acceleration?
Yes, it just depends on how you define which way is "positive". If you define the "backwards" direction to be the positive direction, acceleration will be positive when going "backwards". Note that if we define the axes like this, going "forwards" will give the car a negative acceleration.
Does a hummingbird fly backwards and sideways?
Many birds can fly backwards by flapping their wings just right. It is a myth that only hummingbirds can hover and fly backwards. I have seen small to large hawks hover in still air, and the smaller ones like kestrels have been seen to fly backwards.

Why are batteries negative and positive?
Because of negative charges and positive charges. And because in an electric circuit electrons flow from negative to positive and if the battery wasn't marked you wouldn't know which way to put it in. If put in backwards it would be like trying to drive your car down a one way street filled with traffic, not very good.

Do you mean as in why is there no such thing as negative time? Then it is because time is always positive, signifying a continuos movement of time. A negative time representation would mean time is backtracking, or going backwards, which would be nonsensical for a representation of time.
