. Wild neighbors: out-door studies in the United States. Animal behavior. 78 11 VLB XEIGHB OKS it exists perfectly in the quaint little sea-horse (Hippocampus), which is a poor swimmer, and rests by hooking its tail around a bit of sea- weed or coral, or through a hole in a broken shell, thus an- choring itself securely. A service of the same nature is per- formed by the tail of many birds that are accustomed to climb about the trunks of trees, and cling to upright rocks, etc., in- stead of walking on the ground or perch- ing upon the branches. Familiar examples are the woodpeckers, nut- hatches, creeping- wrens (Certhiadae), and swifts. Whenever these birds rest a moment they press the tail hard against the bark or other surface to which they cling with muscular toes, and lean upon it. Such a leverage is very important to enable the woodpeckers and nut- hatches to deliver their sturdy and repeated blows ; and without such a support the swift could hardly hold itself, as it does for long periods, at rest. ^-•rr -\\ Prehensile Tail of the 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 Ingersoll, Ernest, 1852-1946.
