Bird watching is a popular activity and one where there are few barriers to participation. Both young and old can participate and from any geographic location; you can watch birds in your backyard through kitchen windows or venture out to more wild areas. With this ready access to living birds, what role do bird collections play?
One of the greatest advantages is that specimens allow for up close inspection, for as long as desired. This can be particularly helpful when you want to study a species that is difficult to find in its habitat, when you’re just learning how to identify a species, or when you want to compare features from different individuals.

Bird collections are used for all sorts of research. For instance, museum oology collections were used to identify the effects of DDT on bird egg shells, which lead to banning the use of this hazardous substance. Specimens are used to track changes in a species’ range – check out the range maps the next time you open an identification book; data from museum collections are often used in the creation of these maps.

Specimens that are taxidermied in a behavioral posture are utilized frequently for exhibits. These specimens help illustrate behavior and bring them to visitors who may not have the opportunity to see them first hand in the wild. In order to successfully convey the true nature of an animal, taxidermists need an understanding of how musculature works, but also have an understanding of the animal. Extensive observation of living animals aides in the understanding of a particular species’ behavior, how an animal moves and balances as its walks, and how it interacts with other animals.

The next time you visit the Nature Museum, take a little extra time to study the specimens on display. Note their particular features – the shape of their beaks, the differences in the shape of their feet, the coloration of their feathers. What can you impart from these features about their diet or their activities? Through this observation, you may gain a more thorough understanding of the animals living in this urban nature environment and even spot them more easily in their natural habitat.
