He would go from town to town, "travelling up and down as a stranger in the earth, which way the Lord inclined my heart; taking a chamber to myself in the town where I came, and tarrying sometimes a month, more or less, in a place"; and the reason he gives for this migratory habit is that he was "afraid both of professor and profane, lest, being a tender young man, he should be hurt by conversing much with either."
The song and insectivorous birds - thrushes, flycatchers, vireos and woodpeckers - of this latitude, are well represented, and the high plateaus (particularly the Pocono plateau) have especial ornithological interest as the tarrying-places, during the migratory seasons, of many species of birds whose natural breeding ground is much farther north.

Partridges, woodcock, snipe, &c., are among the game-birds; but all kinds of small birds are also shot for food, and their number is thus kept down, while many members of the migratory species are caught by traps in the foothills on the south side of the Alps, especially near the Lake of Como, on their passage.

In the south-east farmers are often compelled to retire with their flocks and herds before the thousands of huge, migratory vampires, which descend suddenly on the pastures and are able in one night to bleed the strongest animal to death.
The insect fauna of Mexico covers a very wide range of genera and species which, like the other forms of animal life, is largely made up of migratory types.
When any combination of circumstances has occasioned an increase of the numbers of the lemmings in their ordinary dwelling-places, impelled by the restless or migratory instinct possessed in a less developed degree by so many of their congeners, a movement takes place at the edge of the elevated plateau, and a migration towards the lower-lying land begins.
Where the movement was really of a migratory character it may generally be ascribed to external pressure, in particular from the Huns and the Avars.
Further, that the tribes were not normally of a migratory character, as Strabo seems to imply, is shown by the existence of sanctuaries of immemorial age and by frontier ramparts such as that raised by the Angrivarii against the Cherusci.

It seems probable, therefore, that marine animals found migratory conditions between these regions, probably by way of northern islands.
The birds of Canada are mostly migratory, and are those common to the northern and central states of the United States.
The general results of the two movements in Europe have been thus summarised by Dr Sundbarg: Differences tend to be smoothened out, of course, in dealing with a population so large and varied as that of a continent, but the figures suffice to show the contrast between the early part of the century and the period following the great migratory movements to the new goldfields.
For "fig-pecker"), a small migratory bird of the warbler (Sylviidae) family, which frequents fig-trees and vineyards, and, when fattened, is considered a great delicacy.
