GOMEZ, Viviana E.. Birds in the General San Martín Park (Mendoza): Distribution and characteristics. Multequina [online]. 2006, vol.15, n.2, pp.81-95. ISSN 1852-7329.

Birds of General San Martín Park (Mendoza-Argentina) were surveyed. Their zones of action were defined, seasonal changes in composition and structure were analyzed, and observations on ecology and behaviour of birds were made. The work was carried out between January 2000 and January 2004. For the surveys, the 420 ha of the park were divided into 11 areas, called ornithological areas, according to the principal avenues and floristic differences. Four areas were studied on a daily basis, staying for 30 minutes in each one during three days a week. Behaviours, action areas, and daily and seasonal abundance were recorded. Sixty-three bird species were recorded belonging to 25 families and 14 orders. Passeriforms was the most representative order and Tyrannidae the most diverse family. The highest daily abundance coincided with sunny days after a rain. The period of highest abundance coincided with the arrival of migratory species. The most diverse area was characterized by its variation in exotic and native plant species.
