202 Management of Cages 



The height within is 10 feet to the point from 

 where the roof springs ; the two outside flights are 

 10 feet, with a flat roof of wire meshing reaching 

 to the broad eaves, underneath which the height is 

 increased. The middle pen has a semi-circular dome, 

 reaching as far as these eaves, and is 14 feet at its 

 highest point. 



In this pen are some glossy ibises, small waders, 

 such as knots, and also plovers. 



On either side of them are, in one flight, the 

 parakeets, larger finches, and a few foreign pigeons ; 

 whilst on the other are smaller finches and insectivorous 

 birds, such as Pekin and blue robins, Australian 

 finches, &c. 



The basin in the concrete floor is larger and deeper 

 for the ibises than it is for the smaller birds. 



When broad eaves are built, the food can be placed 

 under their shelter instead of inside the roosting- 

 houses. 



The birds come in and out through open windows, 

 which can be closed in very cold weather, and still, of 

 course, admit the light. 



The aviaries are built upon ground that slopes to- 

 wards the south and west ; and by a wood, on rising 

 ground immediately behind them, are sheltered from 

 easterly and northerly winds. It is a mistake to over- 

 crowd, because many birds of various kinds are sure to 

 disturb each other, and give less satisfaction in the 

 end ; for one of the chief pleasures is to suddenly 

 come across a row of four or five plump young 

 parakeets of some kind or another seated on a perch
