For example, the U.S. Biological Survey and the U.S. Fish and Wildlife Service obtained records for more than 250,000 stomach sample records for some 400 North American bird species.  While that represents a lot of dead birds, this earlier literature continues to be of importance to our understanding of the geographic distribution and seasonality of foraging in birds.

While that may be a lot of dead birds, what has been far more destructive is habitat loss & degradation, yes?  I imagine that the loss of these test birds was inconsequential in the scheme of things, given populations at that time.
