Red-fronted Coot is a scares bird in the Sanctuary. Only 30 birds are present here (and in Peru). It is possible to confuse this bird with Andean Coots shoving a red front shield. But Red-fronted Coot has a more flat front shield and more white at the tail than the Andean Coot. It is also smaller than this species. The colour of the bill and the upperparts also distinguishes Red-fronted Coot from Common Moorhen.
