2. Why Bird Poop Is White?
The answer is that birds, unlike mammals, don’t produce urine. Instead they excrete nitrogenous wastes in the form of uric acid, which emerges as a white paste. Owners of red cars, look out! A study in England found that red cars are most likely to be the target of bird droppings.
3. What colours birds can see?
There are two types of colour vision in birds: violet sensitive (VS) and ultraviolet sensitive (UVS).

8. Why Are Moths Drawn to Artificial Lights?
