Osbahr, Karin | 2006-07
At the present time the wetland system at the Sabana de Bogotá (Colombia) ineludes only remaining fragments. One of them, the Guaymaral wetland at the northern border of the city, is also affected by pollution, water drainage and filling for urban and agricultural purposes. Observations of the avifauna were done during one year including the register of activities such as foraging, resting, singing and cleaning at the western, eastern northern and southem zone of the wetland. Characterization of the vegetation was made additionally for each zone. 21 families of birds distributed in eleven orders and 49 species were identified. The analysis of the activity data in relationship with the vegetation at each zone showed higher habitat use at the western part. Foraging at the western and northern part of the wetland has shown higher mean valúes with statistical differences. The use of stratified vegetation was also important at the eastern and northern zone, even the relative abundance of the plants is determinant for habitat use expressed in terms of the analyzed activities.
