The members of this family afford an excellent, opportunity for 

 niip:ration notes. They ai-e generally known, and any careful person 

 can make the observations. Their movements are greatly regulated 

 by Treather. 



There is a favorite region two miles south of my home where Whip- 

 poor-wills and Brown Thrashers may be found from two days to two 

 weeks earlier than they reach me. For several years dates have been 

 kept that establish this. Mr. 0. M. Meyncke reports hearing the un- 

 mistakable voice of the Whip-poor-will in Highland Township March 

 2, 1897. The unprecedented warm weather of the previous few days, 

 resulting in unusual storms, may have induced its exceedingly early 

 appearance (The Osprey, Vol. T., May, 1897, p. 123).

In sixteen years, the earliest date of first arrival at Brookville was 

 in 1893, as given, and the latest, April 26, 1881. In the southern 

 half of the State it is generally common between April 5 and 20; in 

 the northern half, between April 17 and May 5. They mate soon after 

 arriving. I noted them mating April 25, 1887. Eggs are usually 

 found from May 1-10, at Brookville. The two eggs are usually laid on
