Objective: This investigation had as objective to describe the tropic activities of the heron family Ardeidae) in units of Vegetation and Environment (EVU) of the coastal wetland Buenavista (CBH), La Guajira (Colombia). Methods: The CBH was divided into four sampling stations and five EVU's: beach (B), aquatic vegetation (VA), quagmire (Q), sand bank (SB) and open water (WO). The observations were carried out through censuses in points 25 fixed radio m., during 30 min. Findings: 340 individuals were sighted, of which the majority is found in the Q by the conditions of the place for food. The 71% of the individuals were found foraging, a fact that is given when the bird enters its peak or more than half on the substrate in search of food and 29% feeding activity; it is considered that the bird captures with his beak the dam and engullirla achieved. Application: The diversity of the herons was low, it was determined that the abundance of some species is due to the resources that offers this habitat and anthropogenic activities.
