already provided with nests, as those which 
were before used, with a little trimming 
and dressing, answer the same purpose 
for several years; it is also not unusual to 
see them regularlyvisited, and even re- 
• paired in autumn. The great difficulty of 
building lies upon the younger birds, who 
have had no nest before; after their young 
have taken wing, they forsake their nest- 
trees, but return to them again in October 
to roost; but as winter comes on seek the 
more sheltered lodging of some neigh- 
bouring wood ; but generally first assemble 
at some usual place, and then fly off to- 
gether. 
It appears that every distinct colony of 
Rooks has its appropriate territory, or as 
a fox-hunter would term it its country, 
and that these bounds are carefully ob- 
served. It appears also, that very nearly 
the same range or beat is traversed by 
them every day, allowing for such devi- 
ations as arise from having their haunts 
molested, and their ordinary course inter- 
rupted by guns and Crow-keepers.
