having the top of the head and nape of the neck chestnut^ the 
cheeks purer white, and the eyebrows white. The females 
are not to be distinguished from those of that species. 
162. Passer salicicolus, Vieillot. The Spanish Sparrow. 
This is another of the chestnut-headed Sparrows/ and is 
local in distribution on both sides of the Straits. It is in 
some places very abundant; and, as is well known, they 
often build under the nests of the larger birds of prey. I

The females resemble those of the common Sparrow. The 
adult males have the upper part of the plumage much marked 
with black.

nesting in May in holes of rocks. 
The adult male has a yellow crescent on the throat ; in the 
female this mark is much fainter.

" Found near Tangier as a common resident ; others 
migrate in immense flights, which pass north in February and 
March, returning in October and November.^^ — Favier. 
This species, another of our common British birds, is extremely 
abundant on both sides of the Straits. Many are resident, 
nesting during the month of May ; and hundreds are caught 
in August and September and brought into the markets, 
where they are exposed for sale in large bunches. The 
Greenfinch is also a very common cage-bird ; for sometimes 
I have seen as many as twenty, each in a separate cage, 
hanging outside the wall of a house. What its merits as a
