If the owl is a sober and wise bird he forgets all about it when he woos his mate. Such awkward dancing and foolish boo-hoo-ing is never seen except when the owl is trying to choose a mate for life. But he makes up for his awkwardness when there are eggs to sit upon, for the owl is the best husband a bird ever had. When there is room in the old hollow where the nest is he will sit on the eggs with his wife and help her hatch the puffy little owl children. Owls are the best of parents, too, for they will risk their own lives freely to protect their young. If their nests are robbed and the old birds can find where their young ones are caged they will come daily with food for them though they are in great danger in doing so. They lay their eggs earlier than other birds, and often the falling snow covers the back of the sitting bird. The warmth of her body melts it so that water runs gently down through the nest and forms icicles that hang below and glisten in the sunshine to tell of the faithful conduct of the mother owl. Small birds, as a rule, hate owls, and they delight in getting round these great awkward fellows whenever they can catch them by day and doing all they can to hurt their feelings. Bird-catchers sometimes catch small birds because they are so fond of teasing owls. An owl is caught and tied to a tree. The tree is covered with sticky stuff called bird lime. As soon as a little bird sees the owl in the tree he cries to his friends and they come in great crowds to tease the owl. But the small birds find their desire to torment ends in their own capture, for they cannot get away from the bird lime until the trapper comes along and gathers all the little birds that are hanging to the sticky limbs and twigs about the big bird they were trying to tease. THE DUCK MOLE. We are indebted to Dr. George Bennett for the first good description of the duck mole (_Ornithorhynchus anatinus_) which was an object of wonder to naturalists long after its discovery. This enthusiastic investigator traveled to Australia for the sole purpose of observing the animal. Up to that time little was known of it. We simply knew that the duck mole lives in the water and was persistently hunted by the natives, as it yielded a savory flesh and laid eggs. The latter discovery was made by Caldwell in 1884.
