TAILOR BIRD.
There is one thing worthy of consideration, however, in studying the Birds as a whole, before taking up individuals; and that is their wonderful intelligence in the building of their nests and the care of their young. It is difficult to understand this intelligence as exhibited in Birds. In the Mammals, whose organization approaches nearer to our own, we are enabled partly to comprehend their joys and griefs, but in the case of Birds it is difficult to understand their sensations.
To explain this mystery a word has been invented which proves generally satisfactory. Thus we call the sentiment which leads the Birds to perform so many admirable actions, instinct. The tenderness of the mother for her young for instance—a tenderness so full of delicacy and foresight, is, we say, only the result of instinct. It is agreed, however, that this instinct singularly resembles the intelligence called reason.
Take the intelligence that is shown in the majority of Birds in the nest building. The Tailor bird—an East Indian Bird related to the Warblers—shows rare intelligence in constructing its nest by stitching together the leaves of plants; and as we study the individuals of the different families of Birds we will find numerous instances of this marvellous quality commonly known as instinct.
Birds have been arranged in groups and families in various ways by different Naturalists, but the most satisfactory classification is the division into six great families. First, the Raptores, or Birds of Prey; second, the Natatores, or Swimming Birds; third, the Grallatores, or Wading Birds; fourth, the Scransores, or Climbing Birds; fifth, the Gallinaceae, or Domestic Birds; sixth, the Passerines, or the Sparrow Family.
BIRDS OF PREY.
The numerous Birds classified as Raptores, or Birds of Prey, are divided into two great families—the Owls or Nocturnal Birds of Prey, who hunt and kill their prey during the night; and the Diurnal Birds of Prey, including the Falcons, Eagles and the Vultures, who seek their food during the day.
All the different Birds belonging to this order are characterized by a strong, hooked and sharp-edged bill, strong legs covered with feathers, four toes, three in front and one behind, which are usually very flexible, and provided with strong talons. As their name indicates, they live by plunder and blood-shedding. They correspond in the class of Birds with the Carnivora among Mammals. Like them, they live on animals, either dead or living; like them, too, they possess the strength and cunning which are necessary to secure their victims.
The Birds of Prey do not possess any of the graces and power of song which characterize other races of Birds. Their only utterance consists of harsh cries or strange and plaintive sounds, and it is very seldom that their plumage is gay or attractive. Destruction is the sole object of their existence, and they are the terror of the rest of the feathered creation.
They are found over the whole surface of the globe. The larger species inhabit lofty mountains, or seek a hiding place in solitary cliffs.
