Ornithologists will not fail to observe how beautifully the 

 present bird represents in Australia the well-known Kestrel 

 of the British Islands, which it closely resembles in many of 

 its actions and in much of its economy ; it flies over the whole 

 of the southern parts of Australia, and that it extends far 

 towards the northern portion of the country is proved by 

 Gilbert having found it, as well as its eggs, during Leichardt's 

 expedition from Moreton Bay to Port Essington. 



Mr. Caley states that it is a migratory species, but I am

 cured in New South Wales in May and June, while mine were 

 obtained at the opposite season of December, when it was 

 breeding in many of the large gum-trees on the rivers Mokai 

 and Namoi ; probably some districts are deserted for a short 

 time and such others resorted to as may furnish it with a more
