Notes

(v; ph ML 68427311 ) M New record. Initially, five individuals were observed on 11 February 2011 and then a group of eight was photographed on 10 January 2013, at Hacienda el Escobal ( 900 m a. s. l.). In the Municipality of Ibagué Initially, five individuals were observed on 11 February 2011. Later, a group of eight was photographed on 10 January 2013 at Hacienda El Escobal ( 900 m a. s. l.) in the Municipality of Ibagué (Fig. 4 a View Figure 4 a ). The individuals were observed on the water mirror in groups comprising females and non-reproductive males, located with native species of ducks ( Anatidae ) and cormorants. The records coincide with other observations made on those days in Bogotá ( Colombia), suggesting an unusual migration route of this species during some seasons. These records are the first for this migratory species in the Upper Magdalena Valley. These observations, like those for other migratory ducks that arrive sporadically in the Municipality of Ibagué, suggest an alternative route for this species.
