Birders have long explored the Amazon River and its tributaries, as theses waterways are home to a diverse collection of avian species, many of which are rarely glimpsed outside of the region. Although the Amazon River basin boasts more than 1,500 unique species of birds (roughly one-third of the world's population), many travelers on IE's Amazon River cruises have become entranced by the vast collection of marsh birds that have been known to populate the region.

One of the more beautiful species inhabiting the marshes of the Amazon is the white-headed marsh-tyrant. At only 12.7 centimeters in length, the small birds may be easy to miss, but as the sole representative of the Arundicola genus, birders will want to make the effort to spot the cute flycatcher.

If vacationers would prefer to spy wading birds, the green ibis is a large, stunning bird that can typically be seen walking alone through the boggy areas of the river. These birds have a bit of a bad reputation, as they have been recorded as harassing sunbitterns who nest in their vicinity.

Other marsh birds that have been spotted in the area include oriole blackbirds, yellow-headed caracaras and the black-capped donacobis.
