but I found six Wilson's, three Mourning, and two Connecticut 

 Warblers. These three species are rare here as a rule, but this

 and departure, and it will be seen that most of the latter dates are 

 later than any previous records for this region. In the appended 

 list I have given the earliest dates on Avhich most of our spring 

 migrants were observed here this year.
