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.
The duck mole is about two feet in length, six inches of which are included in the tail. The males are larger than the females. The legs are very small, all four feet being five-toed and webbed. All the toes are very strong, blunt, and excellently adapted for digging. The middle toes are the longest. The tail is flat and is broad at the end, the extremity being formed by long hairs. It is abruptly cut off, and in old animals is either entirely naked beneath or covered with a few coarse hairs. In young animals it is quite hairy. The adult animal has only four horny teeth in its two jaws, of which the upper front tooth is broad and flat and resembles a grinder.
The fur of the duck mole consists of a coarse outer coat of a dark brown color with a silvery-white surface tinge, and a very soft, grayish inner fur, similar to that of the seal and the otter. A peculiar fish-like odor is given forth by the fur, especially when it is wet. The Australians, however, are very fond of the flesh of the animal in spite of its disgusting odor. The duck mole is said to be fondest of calm spots in rivers filled with aquatic plants and the banks of which are shaded by the dense foliage of trees; and it constructs more or less complicated burrows in the banks. A tunnel about eighteen feet long terminates in a large chamber, both the chamber and its approaches being strewn with dry aquatic plants. The chamber usually has two entrances, one below the surface of the water, and the other about twelve inches above.
The duck moles are seen at all times in the rivers of Australia, especially during the spring and summer. They emerge from their retreats at dusk, though they sometimes also appear in the day time, searching for food. When the water is clear, the observer can follow with the eye the movements of the animal as it dives and reappears above the surface. It likes to stay near the shore, amidst the mud, searching for its food between the roots of the plants, where insects abound. The mollusks which it captures in its forays it stores temporarily in its cheek-pouches and then consumes them at greater leisure.
