GENUS AQUILA BBISSON. 



B. 39. R. 449. C. 532. G. 211. U. 349. 



128. Aquila chrysaetos (LINN.). Golden Eagle. Resident; rare. I am in- 

 formed by Dr. G. K. Rumsey that a pair nested for several years in the south- 

 eastern part of Comanche county, on a high gypsum ledge, and as proof that 

 he was not mistaken, says that the legs of a young bird captured were feathered 

 to the toes. The late rapid settlement of the county has put a stop to their 

 breeding there. Begin laying about the middle of March. Nest usually on 

 the shelves of high, steep rocky cliffs. May 5th, 1884, I found at Julian, Cali- 

 fornia, a nest placed in and near the top of a tall pine tree a huge platform 

 structure composed of sticks and twigs, and lined sparingly with grass, moss, 

 and a few feathers. Eggs, two or three; 2.90x2.25; white, occasionally un- 

 marked, but usually spotted and blotched with various shades of drab to red- 

 dish brown, and a few faint purple shell markings; in form broadly subspher- 

 ical.
