2012-01-28 What bird has the longest tongue relative to body size?
Wrynecks have the longest tongue. It is two-thirds
of its body length excluding the tail. The Wrynecks
- genus Jynx - are a small but
distinctive group of small Old World Woodpeckers. They have large heads, long
tongues which they use to extract their insect prey and have two toes pointing
forward, and two backwards. Zygodactyl feet. Their diet is mainly made up of ants
and occasionally insects, which they find in decaying wood or almost bare soil.
There are two species, the Eurasian
Wryneck and the Red-throated Wryneck.
The Eurasian Wryneck - Jynx torquilla - is small sparrow-sized birds, appearing greyish
overall, with brown and buff mottling. They have a contrasting dark band
running down from the back of the head onto the back. They feed almost
exclusively on ants and unlike other woodpeckers, are seen mainly on the
ground, and do not often climb up vertical trunks or branches.
The Red-throated Wryneck - Jynx ruficollis – has
populations scattered across sub-Saharan Africa, including one confined to South Africa and Swaziland. It is highly
specialized, living only in grassland and feeding exclusively on ants and
termites. This bird’s long tongue is capable of extending more than 60 mm past
the tip of the bill and covered with a sticky mucus secretion from the
salivary glands. This weapon is flicked out at amazing speed to
gather beakfuls of ants.
