On Ofimmenfal Aviaries. 105 



nine months in the year. I have had many generations born 

 in my aviary : they require an abundance of snails and worms 

 during the breeding season. The most beautiful are the 



Turdus Viscivorus Missel Thrush 



— — Musicus Song Thrush 



Merula Blackbird 



Torquatus Ring Ouzel — the three 



first are the only ones 1 possessed. 



Of the genus loxia, I have kept only the 



Loxia Curvirostra Cross Beak 



Pyrrhula Bullfinch 



Chloris Greenfinch ; 



but they may all be kept with great facility. The loxia cur- 

 virostra, the cross beak, is very ornamental and amusing ; but 

 their beak is an instrument of great mischief, and they com- 

 mit much havoc by barking the trees, and destroying the wood- 

 work of the aviary. The other members of the genus are 

 easily kept, and the loxia pyrrhula, or common bullfinch, is 

 one of the most beautiful of the inmates of the aviary. It is 

 scarcely possible, however, to keep more than one pair, unless 

 the aviary be very large, as they fight during the season of 

 love with most unrelenting pertinacity. The genus emberiza 

 are easily kept; but I have only had one species, viz., embe- 

 riza citrinella, or yellow hammer, a very pretty bird, although 

 its note is rather unpleasant. The genus fringilla is the chief 

 ornament of the aviary : of these I have kept specimens of the 

 following, without any difficulty, for a very long time, viz., 



Fringilla Domestica House Sparrow 



Montana Tree Sparrow 



Coelebs Chaffinch 



Montifringilla Mountain Finch 



These birds all breed in the aviary, and by their familiarity
