Photos by Dr. C . William Beebe Iguanas in Mexico can be approached closely by a person on horse back, from which position this was photographed. They show how flight may have been initiated in birds by leaping, sprawled out flat, from high trees. Their flesh is more tender and sweet than chicken meat (see also page 545). The nests of giant tropical orioles, orcaciques, inMexico are pendant structures 3and 4feet inlength. They, areusually built out on the very tips of slender branches, sothat they areprotected from the attacks of arboreal beasts ofprey. Often, asintheabove photo graph, there is a littlesubsidiary chamber atthesummit, which isused by the male bird as aroosting place when hismate issitting onthe eggs below.
