fir-trees, twelve feet from the ground ; eggs three, dull 

 yellowish-brown, with dark reddish-brown blotches." 



A single egg before me, kindly loaned for descriptions 

 and figure by George A. Boardman of Milltown, Me., is of 

 the above color. It is admirably figured, fig. 1, plate I., 

 in this volume. It is a trifle more pointed than the eggs 

 of rapacious birds usually are, and measures 1.50 inch in 

 length, and 1.14 inch at its greatest breadth.
