    • Why can't ostriches fly?

      Q: Why can't ostriches fly?

      A: Ostriches lack the ability to fly because their wings are far too small to generate sufficient lift for their 200-pound bodies. This is the same reason that their relatives, called the ratites, lack the capacity for flight. To cope with such an apparent competitive disadvantage, these birds have evolved large size and great speed. All ratites live in the Southern Hemisphere, and scientists believe that they share a common ancestor.

    • What are the differences between male and female canaries?

      Q: What are the differences between male and female canaries?

      A: There are three ways to differentiate between male and female canaries: genital inspection, color appearance and early song. Breeder Sebastian Vallelunga considers inspecting a sexually mature canary to be a virtually foolproof method, the male having a pseudo-penis that protrudes from his vent, while a female has a round dome protruding above the vent. Females ready to breed have an even, torpedo-shaped belly that narrows at one end.
