Premise: The Mus??e Camargais at Albaron gives a glimpse of the traditional lifestyle of the area, and sets you off on a 3.5-km (2-mile) guided walk through the marshland, and the Parc Ornithologique at Pont de Gau allows you to watch a number of bird species without long hikes into the interior.

Hypothesis: There are no birds in the Parc Ornithologique.
Relation: contradiction
