1008 KEPOKT OF STATE GEOLOGIST. 



Koy Hathaway took a nest containing six well incubated eggs at "Red 

 Key, April 28, 1895. The nest was on the limb of an apple tree in 

 an old orchard, twenty feet up. It was composed of sticks, straws, 

 grasses, weed stems, rags, twine, pieces of cornstalks; lined with 

 chicken feathers. It was also used by the pair in 1894. Messrs. L. 

 A. and C. D. Test found nearly fully fledged young at Lafayette, May 

 15, 1890. They note some six or seven pairs breeding within three 

 or four square miles adjoining that city that same spring. Prof. B. 

 W. Evermann notes a set of six eggs taken at Pittsburg, May 10, 1884. 

 Near Kichmond, a set of eggs was taken June 22, 1888 (H. N. Mc- 

 Coy), and another, containing fresh eggs, June 6, 1890 (L. A. and C. 

 D. Test). 



Mr. L. T. Meyer, in remarking that they are prolific layers, says 

 in the spring of 1886, in Lake County, the first laying of one of these 

 birds was accidentally broken. It built another nest near by, and 

 some boys broke the eggs. The third time it built in an orchard, 

 and reared its young by the last of July. Early in August they begin 

 to wander away from their breeding places, and frequently disappear 

 from well known haunts in September. They have usually left the 

 northern part of the State in October and most of the southern por- 

 tion by November 1 to 15.
