“When in my residence in Carolina and Florida, I have seen vast flights of the house swallow (hirundo pelasgia) and bank martin (hirundo riparia) passing onward northward toward Pennsylvania, where they breed in the spring, about the middle of March, and likewise in the autumn in September or October, and large flights on their return southward. And it is observable that they always avail themselves of the advantage of high and favouralbe winds, which likewise do all birds of passage.”
