Teacher: “What is the difference between a bird and fly?”
Student: “Well…a bird can fly…..but a fly can’t bird.”
Interesting Fact: Unlike humans, birds can see ultraviolet light. This enables kestrels to make out the trails of urine that voles, a common prey mammal, leave as they run along the ground. Like neon diner signs, these bright paths may highlight the way to a meal—as has been observed in the Eurasian Kestrel, a close relative.
