BLACK-AND-WHITE WARBLER 



A few Black-and-white Warblers winter in Southern Florida, so that 

 the only way of knowing the beginnings of spring migration in that dis- 

 trict is from the records of the striking of the birds at the lighthouses. 

 Both at Alligator Reef and at Sombrero Key lighthouses in Southern 

 Florida, this species begins to strike early in March. Thence, northward 

 the progress is so slow — an average of twenty miles per day — that it is the 

 middle of May before the species has reached the Gulf of St. Lawrence.
