ABSTRACT
Like other areas of technology, software and hardware for observational research have advanced rapidly in the last few years. The software possibilities for researchers to enter observations, range from homemade freeware programs developed by other researchers for use in their labs, to polished commercial packages costing thousands of dollars. Smart phones, tablet computers and Netbooks have lowered the costs and expanded the choices of software and hardware. Digital video recording is available as inexpensive stand alone equipment and on most cell phones.
