A, Foot of Yellow Wagtail; B, Foot of Water-ouzel: C, Conirostral beak (Hawfinch); D, Dentirostral beak (Shrike) ; E, Tenuirostral beak (Humming-bird); F, Fissirostral beak (Swift). In accordance with the form of the beak, the Insessores have been divided into four great sections or sub-orders, known as the Conirostres, Dentirostres, Tenuirostres, and Fissirostres. Sub-order i. Conirostres.—In this section of the Insessores the beak is strong and on the whole conical, broad at the base and tapering with considerable rapidity to the apex (fig. 195, C). The upper mandible is not markedly toothed at its lower margin. Good examples of the Conirostral type of beak are to be found in the common Sparrow, Hawfinch, or Bullfinch. The greater number of the Conirostres are omnivorous; the remainder are granivorous, or feed on seeds and grains. The sub-order includes the families of the Horn-bills (Buceridce), the Starlings (Sturnidm), the Crows {Corvidce), the Cross-bills (Loxiadce), and the Finches and Larks {Fringillidcs:). In the Horn-bills the conirostral shape of the beak is masked, partly by its being of very great size, and partly by the fact that above the upper mandible is placed a hollow appendage.
