LOBOS, GABRIEL; BOBADILLA, PATRICIO; ALZAMORA, ALEJANDRA  y  THOMSON, ROBERTO F. Abundance and activity-pattern of birds at a landfill in central Chile. Rev. chil. hist. nat. [online]. 2011, vol.84, n.1, pp. 107-113. ISSN 0716-078X.

Landfills are considered an attractive habitat for several bird species; however, implications of this condition have not yet been explored in the country. We monitored birds' activity patterns that use a landfill located in the vicinity of Santiago, Chile's capital. Main birds recorded in the area were, Kelp gull (Larus dominicanus Lichtenstein), Chimango caracara (Milvago chimango Vieillot), Cattle egret (Buculbus ibis Linnaeus) and Black Chested Eagle (Geranoaetus melanoleucus Swann). Kelp Gull was the most abundant species, (with values between 358 to 1950 individuals per day) and that also displayed a bimodal behavior linked directly to the landfill operation levels. In the case of Black Chested Eagle, we observed a kleptoparasitic behavior over Chimango Caracara which selected organic offal (fishes, innards, meat) for its feeding and that are stolen by the eagle. Finally we highlight simple management activities that should decrease the number of birds in these kinds of facilities.
