1/10 ounce is the weight of a hummingbird (like the weight of a penny!)
2 eggs are generally laid in a hummingbird nest.
1-½ inches in diameter is a typically hummingbird nest (about the size of a golf ball)
2 times their body weight is the amount of nectar hummingbirds will drink every day (most birds only eat ¼ - ½ their body weight).
12 times per second that a hummingbird tongue can move in and out while lapping up nectar.
80 times per SECOND is how fast hummingbird wings can beat!
50 beats per minute that a Ruby-throated Hummingbird heart will slow down to during periods of energy-saving torpor. It usually beats 1,200 times per minute!
