SITUATION - On a 1" in diameter horizontal 

 limb about 15' from the ground and 3' from the 

 trunk of the 25* Walnut in what appeared to be 

 an old pasture, was the exquisite nest of this 

 little bird. The nest was well camouflaged and

 soft plant down and covered with lichens. It 

 was skillfully and beautifully bound to the 

 limb which supported it and to its component 

 parts with silken fibers and spidersilk. The

The four bluish white, oval eggs 

 had a few reddish brown spots and dots dis- 

 tributed fairly evenly except for the larger 

 ends which were more numerous and tended to be 

 wreathed. When I blew the eggs later, they 

 were found to have been incubated approximatel 

 one-fifth.
