So we have a dataset with birdspecies (factor, 4 levels) and activity time (in minutes after sunrise). We want to know if the birds have a heterogeneous use of time. So do they come into our garden at all times of the morning (after sunrise-12pm), or do they have certain peaks. Our histogram shows for some birds that they are active around 1-2 hours after sunrise, but others do not. Is there an actual easy test to check this? The Kolmogorov-Smirnov was suggested, but in a one-sample test, it checks our distribution against a normal distribution. But is there a uniform continuous distribution to check against?
Thanks in advance!
