never goes far inland; returns to the Southern States as soon as the young are able to travel.
11. The Green Heron. Ar elect virescens. Resident in the Floridas; dis- perses over the Union; goes far inland; the greater number return at the approach of winter to the Southern States. 12. The Least Bittern. Ardea exilis. Resident in the Floridas; mi- grates as far as Maine, and throughout the Western Country, far up the Missouri; returns early in autumn to the Southern States. You will see from the above statement, that the Herons are almost similar to our Pigeons in respect to the extent of their migrations, which must appear the more remarkable on account of their comparative size, Ardea Herodias and A. virescens corresponding in a great degree to the Columbct migratoria and C. carolinensis.
