Hi there, I'm hoping to get some help on which statistical test would be appropriate for the data I'm trying to sort out. I am looking at the abundances of birds which are either "Migrants" or "Residents" over three time periods in the spring. I'm hoping to see if there is a significant difference between the number of Migrants and the number of Residents, as a function of the time period. My data are as such (for example):

Time Period Migrant Count Resident Count

Early 1 3

Early 2 4

Mid 0 2

Mid 3

Late
