performance and much upset by even a slight breeze. Their cries are harsh and 
incessant. All authorities testify to the habit of several birds laying in a common nest, 
_ which is usually placed against the trunk of a tree a few feet from the ground ; it is 
composed of a collection of sticks and twigs and partly filled with dead leaves, amongst 
which the eggs are placed. These vary in number, and in one nest Mr. Newton found 
at one time as many as fourteen. ‘The eggs are oval, of a greenish-blue colour, and 
overspread when fresh with a soft cretaceous coating, which shows plainly every 
scratch of the claws of the birds.
