Question
1. In one or two sentences, summarize the information provided in each graph or table
2. For each graph or table, provide a title and a summary of the results
3. Based on the data and where you live,
a) what do you think the impact of a wind farm in your area would be on bird and bat mortality?
b) If a wind farm were installed, what recommendations could you make to reduce bird and bat mortality?
Make sure to discuss your answer in relation to each of the graphs/table.

1.
Graph A represent bat call's frequency at different time.
Graph B accounts for the bat fatalities per turbine search and it also represent the percentage of time per night spent in rain or storm.
Graph C shows causes of birds casualties and their reason
Table 1 represent the bat carcasses picked from different cities in 15 days from 1-15 May to 1-15 Nov.
2.
Graph A represent bat call's frequency at different time, 21:00 hours being the most populated time for bat frequency of around 750 calls.
Graph B accounts for the bat fatalities per turbine search with Site one dominating till 8/23/04 and Site two after that apart from this it also represent the percentage of time per night spent in rain or storm which is continuously incresing from 7/30/04 to 9/16/04.
Graph C shows causes of birds casualties and their reason with windows acoounts for more than 900 milliion casualties, Feral cats comes next with 500 milliion casualties, High tension wires are third with around 200 milliion casualties and other reasons like pesticides, cars, communication towers, hunting, oil waste pits, wind turbines, Electrocution, oil spills and fishing by nets have less then 100 milliion casualties in each(casualties decreasing from pesticides to fishing by nets).
Table 1 represent the bat carcasses picked from different cities in 15 days from 1-15 May to 1-15 Nov, with Auf 1-15 being the most populated day and May 1-15 beaing the least and Buffalo Ridge, MN is the place where most number of casualties are taking place.
3.
a) There are positive as well as negative the impact of a wind farm over bird and bat mortality in an area, positive is they provide shelter during storm and neagtive because bat and birds will crash with the turbine and this will increas the mortality.
b) Light electromagnetic radiation can be applied near a wind farm so that birds and bats can analyse this E-M radiation and divert their path and during storms this E-M radiation can be stopped so that they can take shelter under these farms.
