"The bearded reedling (Panurus biarmicus) is a small, sexually dimorphic reed-bed passerine bird. It is frequently known as
the bearded tit, due to some similarities to the long-tailed tit, or the bearded parrotbill.

This is a small orange-brown bird with a long tail and an undulating flight. The male has a grey head and black moustaches
(not a beard). Flocks often betray their presence in a reedbed by their characteristic "ping" call.

This species is a wetland specialist, breeding colonially in large reed beds by lakes or swamps. It eats reed aphids in summer,
and reed seeds in winter, its digestive system changing to cope with the very different seasonal diets." [Wikipedia]
