121. How do you know? Bird identification (29:18)

Date:
1958
Summary:
Bird identification has escaped the laboratory stage in the past 20 years. Frequently the identification of living things down to the species, depends upon features not really observable. But naming a bird (in some cases even to a subspecies) can now be done quite accurately through a system of field identification. Perfected by outstanding field observers like Ludlow Agrisom and Roger T. Peterson and put into book form and general circulation by Peterson, this system has created a hobby full of leisure for many people. This program will introduce the elements of knowing a bird when you see it, alive and in its environment. Graphic art and film will illustrate how you look for stance, pattern, habits and combinations of marking to identify a bird. Betty Sears, “Discovery’s” artist, appears on this program with the sketch book she uses on birding watching expeditions.
