swamps. The finfoot feeds on aquatic invertebrates, including both adults and larval mayflies, dragonflies, crustaceans, also snails, fish and amphibians. They are thought to be highly opportunistic and take some of their prey directly off the waters surface. They are adept out of water and will forage on the banks as well, unlike the grebes, which they resemble but are not related to. Finfoots are usually seen singly or in pairs. They are very secretive. Even experienced ornithologists see them very rarely, making them a prized sighting for birders and twitchers. Because they are so elusive, it is not known if they spend most of their time in the water, where they are almost always seen, or on land. Their time of breeding varies by area, usually coinciding with the
