dc.description.abstract |
The construction of an electronic surveillance system that can be used to count night-flying birds passing through a 2-D window is presented. The surveillance system has been designed primarily to estimate the number of bats (although they are not birds) flying in or flying out of a cave. In addition to counting bats, this detector can be used to study the population, seasonal variations and the habits of bats and how they react to environmental changes. |
