Puna Ibis vs White-faced Ibis

Puna Ibis

Plegadis ridgwayi

Large579 gWetland

The puna ibis is a medium-sized waterbird, weighing 478–608 g (16.9–21.4 oz) and about 56–61 cm (22–24 in) tall. They can be identified by their dark purple-brown bodies, long neck, and red downward-curved bill. Their plumage has iridescence to it, offering a purple or green sheen. While there is little sexual dimorphism between male and females, a breeding adult can be recognized by its dark chestnut head and neck, with a red face and, and nonbreeding or immature individuals have white streaks on their head and neck, with a duller face. Males are also larger than females. Voice: Usually quite quiet, when disturbed puna ibis vocalize with a call that sounds like a "wut" or "cwurk". Juveniles are known to give a whispering call. The glossy ibis, plegadis falcinellus, vocalize when greeting their mates during nest relief, as well as when chicks are food-begging.

White-faced Ibis

Plegadis chihi

Large617 gWetland

In its non-breeding plumage, the white-faced ibis is very similar to the glossy ibis except that it tends to be slightly smaller and its plumage has a somewhat warmer color. Breeding adults have a pink, bare face bordered with white feathers (rather than a bluish bare face with no bordering feathers), a grey bill, and brighter-colored, redder legs. Adults have red eyes year-round, whereas glossy ibises have dark eyes. Juveniles of the two species are nearly identical. Measurements: Length: 18.1-22.1 in (46-56 cm) Weight: 15.9-18.5 oz (450-525 g) Wingspan: 35.4-36.6 in (90-93 cm)
