below the eye, chin, throat and breast, bright yellow; abdomen 

 and under tail-coverts duller yellow ; sides of body yellowish 

 green streaked with brown ; ear-coverts and moustachial streaks 

 olive-green; lesser and median wing-coverts olive-green; 

 greater wing-coverts, brown tipped and margined with yellow; 

 quills, brown; outer webs margined with olive-green. Total 

 length 4^4 inches, tail ifs inches. The hens in both species are 

 lighter in colour. The young C. tibctana were very much 

 darker than the young C . spinoidcs, the hen in particular 

 showing very little yellow. The Goldfinch hybrids in shape 

 resemble their father, but are slightly larger. In colour they 

 are a pale grey, streaked on both breast and back with a darker 

 shade of the same colour. Two bars of black, and two of 

 huffish yellow, across the wings, give them quite a pretty 

 appearance, especially when viewed from above. 



The first nest was built on the top of a conifer in the 

 month of July ,and being close to the wire roof it was impossible 

 to get a photo of either it or the young ones. The second nest 

 was more accessible as the accompanying photo shows. Two 

 young were reared from the first, and three from the second 

 nest, and I think that when they are in full plumage they should 

 be very pretty birds.

.Sparrows. — This group are very interesting aviary birds, 

 and though some of the species are noisy and self-assertive, I 

 have not found them to interfere materially with the other 

 occupants of the aviary. The species which come within the 

 scope of this article are : 



* Yellow Sparrow ( Pass-cr lutcits). 

 Grey-headed Sparrow (P. diffiisus). 

 Cinnamon Tree Sparrow (P. cinnamomcus). 



* House Sparrow (P. doviesticus). 



* Tree Sparrow {P. montamis).
