604 ^Ii"- I)- A. Baniierman on the 



had four eggs on the 1 Ith of that month. Another nest in the 

 same garden contained only one e^^ on Febrnarv 19th^ but 

 hv the 2rth of the mouth four eggs were laid. 



On ^Nlarch 14th of the same year I found a Chiffcliafi'^s 

 nest built on the ground : it was placed at the foot of a small 

 bush in an exposed position ; the nest was composed of grass 

 and lined thickly with feathers and harmonised perfectly 

 with the dead grass around. It contained four eggs. 

 Dr. Tristram never heard of a nest placed on or near the 

 groundj those which he found were almost always in the 

 crowns of palm-trees and once in a laurel-tree. The 

 colouring of the eggs of this species varies considerably, the 

 red spots differing in size to a great extent. In one clutch 

 which I took the spots were very minute and numerous, 

 predominating at the larger end, and in another clutch were 

 much larger and more scanty. 



Yon Thanner mentions having procured Chiffchaffs here 

 which had '' light plumage and pale yellow tail-feathers."' 

 At the time of my visit to this spot in February 1912, Chiff- 

 chaffs were remarkably scarce. The only specimen that I 

 procured here certainly did not shew any marked differences 

 from those obtained in the north of the island. At the 

 beginning of June of this year Chiffchaffs appeared more 

 plentiful in the private gardens of Las Palmas than I had 

 ever noticed them.
