could crouch so low and at tlie same time make such good 
running. 
About Casa Vieja a few Bustards are to be found near the 
banks of the rivers Barbate and Celemin, where, from the 
nature of the ground, which is intersected by the windings 
and branches of these rivers, which are nearly dry in August, 
it is sometimes possible to stalk them under cover of the 
banks ; and it is very good ground to have them driven over ; 
but the Spaniards there cannot be made to understand such 
work. 
The Great Bustard nests in corn or grass early in May, 
laying two olive-brown eggs marked with spots and blotches 
of dark brown. They have been supposed to be polygamous; 
but I do not think such is the case ; the Little Bustard un- 
doubtedly pairs. The gular pouch, which always exists in the 
old males or Barbones, is sometimes very large and necked in 
the middle, somewhat like an hour-glass, the lower part being 
the largest ; this shape is not constant. Perhaps it is the 
result of extreme age. 
Average length of a male 45 inches, of a female 36.

'' The Little Bustard is abundant in the vicinity of Tangier 
in small flocks, which are very wild and wary. They migrate 
to the north during the months of April and May, returning 
in October and November. In addition to these migratory 
birds, great numbers are resident during the nesting-season. 
The males do not attain the full breeding-plumage until their 
third year, and by October regain the dress of the females.^^ —

My experience of the breeding-plumage of the Little Bus- 
tard is rather different from the above ; for, as far as I have 
been able to ascertain, the males lose the black markings of 
their nuptial dress by the end of August, if not before. I 
could not make out the exact period ; but I never saw a black- 
marked male which had been killed after the middle of August.
