Comparison of bird migration In the US between peak migration in September and migration in November
Birdcast migration data was used to analyze migration data between September and November. The differences between the two months demonstrate the effects of temperature on migration traffic/migration timing. Taking data from September 22 – 28, and November 9 – 15, average active radars were counted for each night and the two weeks were compared using a 2 sample t-test. The results showed that migration in the September week was significantly (p=0.000201) higher than the November week, which shows how important temperature is as a factor in determining the timing and traffic of migration.
