Random Sampling of hunter data, when performed objectively, is the most accepted form of determining trends.
Aerial Surveys: -Audubon samples bird trends in a similar way, by placing capture nets in the same place(comparable to flight paths), for a specified time period(like 6:00 AM-12:00 AM) and maintain the exact routine for years.
