News - January 2010
After a month we have discovered the rosy-billed pochard family with the fulvous whistling-duck. They have grown and their plumage looks like the adults'. The rosybills are all in female plumage, The juvenile males have not changed into the adult male plumage yet. The fulvous whistling-duck already shows the black line down hindneck and the creamy bars on flanks.
This female rosy-billed pochard has adopted this fulvous whistling-duck. The little whitling-duck clearly differs from her own offspring. Laying eggs every nos and them by birds which normally nest is known as facultative parasitism. Here the host is the rosy-billed pochard. Her duty is not as tedious as that of other hosts since ducks do not feed their ducklings. They only lead them to feeding grounds.
