THE MIGRATION OF BIRHS. - 
Alost New Jersey birds migrate to the south in the fall and return 
north in the spring. There is only a small proportion of our birds 
that remain with us all the year, yet we have quite a number o 
species present during the winter, as a great number come from 
the north to remain with us. The number of our summer birds 
that remain here during the winter depends much on the winter 
weather, yet there are some species that are always with us. 
Ornithologists group birds of any locality under four heads, ac¬ 
cording to the character of their migration, viz., residents, summei 
residents, transient visitants and winter visitants. 
Residents, are those remaining throughout the year. 
Summer Residents, are those coming from the south in the 
spring, breed in the locality and again return south in the' fall. 
Transient Visitants, are those passing through a locality, breed 
farther north and pass hack again on their return south in the fall. 
Winter Visitants, are those coming from the north in the fall, 
remaining during the winter and return north in the spring.
