EXTERNAL STRUCTURAL ADAPTATIONS TO CLtRSORIAL HABITS. Functional radiation is developed to so remarkable a degree in the Class of Birds, that we find representatives of many orders which have become more or less specially adapted to a terrestrial, cursorial life. Examples of these are the Tinamous, almost all the members of the Order Gallinac, the Cranes, the secretary-bird among the Hawks, the road-runner among the Cuckoos, and the Larks among the Perching Birds. Yet in all of these birds, ter- restrial locomotion is indulged in only as an alternative of the power of flight; and, except in the Tinamous, and to a less de- gree among the Gallinae, life on the ground has had no apprecia- ble effect in lessening the wing Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New York Zoological Society.
