Sieve trap: B, common coal sieve, set with one edge raised by stick A, to which is attached the string C, one end of which is held by the bird-catcher at a distance. When the bird, attracted by the bait, goes under the sieve, the stick is jerked out and the sieve falls. Ever-ready bird-trap: D, body of trap made of netting F and A, hoops supporting netting. A, ring to which are attached the wires C, which point backwards. The bait is placed within the body of the trap and scattered through the ring B. Then the bird enters at the entrance A, goes through the ring B, so on past the wires C, which are arranged in a circle to prevent his egress. The bird is removed through an orifice in the back, drawn together with a string at F. Skinning-knife: The handle of this knife should be round, and the blade does not close. Skull of bird (side view): Dotted line from A to B shows cut to Skull of bird, under side: Dotted lines A, A, A, show cuts to be made in removing a triangular piece of bone and muscle, to which the whole or a portion of the brain will adhere. Dissection of a song sparrow, showing male organs of reproduction: 1 and 2, lungs; 3, 3, testicles. The four organs below these are the kidneys. Dissection of a song sparrow, showing female organs of reproduction: 4, lungs; 1, 1, small yellow glands, present in both sexes; 2, ovaries; 3, oviduct. These last four figures are merely diagrams, only sufficiently accurate in outline to convey an idea of the position of the parts indicated. Tweezers for making skins, mounting, etc.: Several sizes are used, but as a rule the points should be longer than those given in the cut. Drying forms fastened to a board, D, skin in the form. I now use these forms detached. See text. Also, see page 54 for a better method of making skins which I now practise. Form of a skin of an oriole: I now use the long label given on page 58. A skin should not be made too full; a dead bird laid on its Straight-nosed pliers: Used for bending wires in mounting. Cutting-pliers: Used for cutting wires in mounting. Body of a bird: E, neck-wire, which should be as long as the neck and tongue in order to reach into the upper mandible. This wire should be wrapped in cotton. B, wire before clinching; G, C, wire clinched; F, tail wire bent in the form of a T at H, a leg wire going through tarsus along dotted line to D. Roughly-drawn skeleton of a pinnated grouse, only sufficiently accurate to indicate the different bones: A, skull; B, B, B, vertebrÆ; furcula of neck and back, or wishing-bone; D, forearm; F, carpus, showing hollow in bone through which the wire is to be passed in wiring the wing; G, end of furcula; H, tip of keel; I, indentations in posterior border of stemma; J, femur; K, tarsus; L, heel; M, pelvis; N, cocyx; O, crest of keel; P, side of keel; X, wire used in mounting skeleton; A, B, ribs. Outline figure of grouse showing external parts: A, back; B, rump; C, upper tail coverts; D, under tail coverts; E, ventral region; F, tibra; G, tarsus; H, breast; I, side; J, throat; N, chin; L, abdomen; M, feet. Outline drawing of a mounted bird: A, A, dotted line to Lower portion of bolt used in mounting large mammals |
