one-half, and depth one and one-quarter inches. The single egg 

 remaining is entirely similar to those described, as far as color 

 goes, and measures .91 X .64 inches. 



Nest No. 3. June 17, 1884. Mesquite, ten feet from ground. 

 Contained three young, just hatched. Saddled very securely on 

 a limb four inches in diameter ; it is very like Nest No. 2, only 

 that it is rather smaller and deeper. The materials are the same, 

 and the gluing with saliva is very apparent. 



Nest No. 4. June 21, 1S84. Oak, ten feet from ground. 

 Contained three eggs, partly incubated. These differ from those 

 already described in having the ground color greenish white, un- 

 spotted for the half toward the smaller end, and in lacking almost 

 totally the faint lilac spotting, and further in having the dark 

 umber markings almost confined to a circular band passing wreath- 

 like around the larger end. They measure .88X.70, .90X.70, 

 and .SS X -6S inches, respectively. The nest does not differ mate- 

 rially from those already spoken of, but is placed in a fork so that 

 two branches support it, while it rests partially on a third limb. 



Nest No. 5. June 21, 1S84. Mesquite, ten feet from ground. 

 Contains two eggs about to hatch. Is identical in material and 

 position with No. 4, being placed in a fork of the limbs which 

 support it. The eggs are not to be distinguished from those of 

 nest No. 1. 



Nest No. 6. June 29, 1S84. Sycamore, forty feet from ground. 

 Contained two young, half-grown. Is a loosely made structure, 

 like No. 1, and is built on and attached to four rather small limbs 

 where they branch. 



This is not the only nest of this species which I have observed 

 at a considerable height from the ground, at least three more 

 being noted last year, but as they are built invariably, so far as I 

 know, in such cases near the extremity of the branch, they are 

 often unattainable. 



The number of eggs would seem to be quite as frequently three 

 as two; and it will be noticed that considerable latitude in choice 

 is manifested as to the kind of tree built in, the height from the 

 ground, and the position and method of placing the structure on 

 the limb or in the forks of a branch.
