Eurasian Penduline-Tit Remiz pendulinus

A very small inhabitant of the wooded borders of marshes where it builds distinctive pouch-shaped nests, often over water. Sharp and pointed bill, rusty-brown back, and black mask (narrow in the female) make it look like a miniature shrike. Juvenile uniform brown and lacks the mask. Often most easily found by listening for its high-pitched whistled call.
