MIGRATION.

visited daily in this way, as well as favourite roosting- 
places: Woodpeckers will even go so far as to dig out 
sleeping holes, where there are none ready to hand, or 
make themselves at home in strange domiciles : take, for 
instance, the case of a Green Woodpecker, which used 
to roost every winter in our Starling box. 
This style of roaming is undoubtedly the pleasantest of 
the three different classes of migration, as may be easily 
imagined, while observing birds or listening to their 
joyous strains. Their food is within reach, and they 
experience all the pleasures of change without feeling 
the bitter pangs of home-sickness ; they have shelter,— 
what more do they require ? The Yellowhammers, Chaf¬ 
finches and Sparrows that frequent our farmyards in 
winter are not such objects of pity as some good souls 
would think, though this pity does not in reality come 
amiss, for it tends to check the detestable love of 
destruction, and secures to these pretty creatures some 
amount of protection. 
From what we have said it will be seen that all birds 
are subject to this last kind of limited migration,— 
both true birds of passage and migrants of the second 
class, at home as well as abroad. Finally, thoroughly to 
understand the meaning of this last migratory movement, 
it only remains for us to consider those birds which are 
neither true migrants nor belong to the second class, 
but only roam in the manner aforesaid, if they ever 
quit the place of their birth. Of these we may mention 
the following, which are natives of Germany:—the 
Golden Eagle, Long-eared Owl, Eagle Owl, TengmalnTs 
Owl, Barn Owl, Kingfisher, Baven, Carrion Crow, Magpie, 
Green, Gray-headed and Pied Woodpeckers, Nuthatch, 
Tree- and Wall-creepers, Green Finch, Tree-sparrow,
