Two types of pigmentary abnormalities in the Andean Coot Fulica ardesiaca (Rallidae) living in the San Pablo Lagoon, Imbabura-Ecuador, are presented. Several adult individuals show a variety of feather depigmentation patterns, which may be classified as partial leucism and progressive graying due to age. Whereas the first one is caused by lack of melanin and is hereditary, the second one is a progressive loss of pigment and is not necessarily hereditary. This is the first case of such pigmentary abnormalities within one meta-population in Ecuador.Se presenta dos tipos de anomalías pigmentarias en individuos de la focha andina Fulica ardesiaca (Rallidae),que habita el lago San Pablo del cantón Otavalo, provincia de Imbabura, Ecuador.
