The scientist is unreliable because he was supposed to be collecting data on why the birds are dying not why people think they are dying. Also the data (as useless as it already is) would be very biased because he is asking people if they think they are contributing to the problem. Its like if you asked cigarette companies if cigarettes were harmful rather than testing to see if they were.
