A challenge

Try to identify them

Clearings in the reinforest such as the wide expanse of the Iguazu river, are the habitat for some of the more agile winged hunters.

Several species of swallows are to be found over this stretch of river though some migrate in winter.

How many can you identify ?

But don't confuse them with swifts.
