The posture of these two white-faced whistling-ducks is a common image in this species. They are preening one another, that is they are allopreening. Preening is a common behaviour in all the species, but allopreening is only observed in those species with strong social ties like the white-faced whistling-duck. With no apparent reason one bird approaches another, directs its bill to the neck and begins preening. The other one reacts doing the same thing. Either adult-adult or adult-juvenile indulge in this activity. Beyond the benefits of preening, keep free from parasites and with tidy feathers, allopreening reinforces the bonds in the group
