in March, seldom making any stay near Tangier ; they pass 
on to the large lakes and rivers." 
On the Spanish side of the Straits the Grey Lag Goose is 
found in winter at the Laguna de la Janda and in the various 
lagoons of the marismas of the Guadalquivir in enormous 
numbers. They generally arrive at tlie former place about 
the 20th of November, the earliest that I noticed in two 
consecutive years being on the 8th of November and the 
25th of October. Commencing their departure about the 
14th of February, they are all gone by the first week in 
March, and seem for the most part to migrate by day. 
Although, like Ducks, they " flight " at night (though, 
as a rule, rather later in the evening and later in the 
morning), they affect particular favourite spots and pools 
without any. apparent reason for their likes and dislikes, 
some places never being frequented by them. 
The Grey Lag Goose can always be easily distinguished at 
some distance on the wing by the ash-grey of the shoulders, 
which colour, when they are flying, is very apparent. They 
make a creaking noise, caused by the stiff primaries, some- 
what resembling the rattling together of dry reeds, which can 
be heard only when they pass very close ; and a very joyous 
sound it is for the sportsman to hear,

On the Spanish side of the Straits this species is much less 
numerous than the Grey Lag Goose ; and it was some time 
before I could succeed in obtaining a specimen for iden- 
tification. As far as my experience goes, I should say the 
present species occurs in the proportion of one to every two 
hundred of the Grey Lag ; but as Favier considers both kinds 
equally common in Morocco, perhaps in some seasons the 
present species may be more abundant than in others. 
The White-fi'onted Goose [Anser albifrons) and the Pink- 
footed Goose [A. brachyrhynchus) I never met with on either 
side of the Straits. As it is possible they may occasionally 
occur, I give the distinctive marks and relative measurements
