AMAZILIA. 295 
Marias Islands between 1865 and 1867; and Mr. Alphonse Forrer also found it when 
at the same islands in March 1881. Two skins, a male and a female, from the last- 
named collector are now before us, and confirm the characters set forth by Mr. Lawrence 
when describing Grayson’s birds. 
Grayson says that birds of this species are very abundant on the islands, where they 
seem to be constantly at war with one another. Sometimes combats between them 
become of a desperate nature. One day, while watching a number of them in active 
motion around some tobacco-flowers, of which they are very fond, he saw two fine males 
after darting at each other for some time at length come to a deadly struggle high 
above his head; they finally clinched each other, each having one of the mandibles of 
the other in his mouth, at the same time scratching with their claws and using their 
wings with the greatest force. Whilst in this situation they wheeled round and round 
and fell to the ground. He then caught both under his hat, but even then, when 
held apart, they showed a desire to continue the struggle. 
Grayson also says that he frequently saw birds of this species dart from their perch 
upon diminutive flies after the manner of a real Flycatcher, and their gizzards when 
examined were always full of minute insects.
