Over the past several decades, widespread road construction in Japan has resulted in an increase in birds being killed by collisions with vehicles. In addition, during more recent years a spurt in construction of high rise buildings has also contributed to bird deaths through collisions. Based on 45 years of data, it can be estimated than an average of 100,000 birds are killed in Japan each year by collisions with vehicles, structures and utility lines and poles. The carcasses of these birds can be utilized to obtain scientific data for research, as well as for specimens to be used in environmental education. Various body measurements can be taken, and the birds can be analyzed for stomach contents, parasites and environmental chemicals such as dioxins. Preservation can be by formalin or stuffing. If stuffing is difficult, the feathers can be preserved as specimens for use in museums, schools and other education programs.
