Description

The Eurasian Teal is the smallest dabbling duck in Europe and a close relative of the North American Green-winged Teal. Males boast a striking chestnut head with a glossy green eye-patch, a barred grayish body, and a distinct vertical white stripe on the shoulder. This particular feather exhibits the delicate, fine gray-and-black vermiculation pattern typical of the adult male's side plumage.

Colour & Pattern

Pale gray base with fine, intricate black vermiculations (wavy lines) characteristic of male teal plumage, coupled with a clean white margin on the edge

Barb Structure

Pennaceous at the distal tip and along the upper margins with tightly interlocked barbs, transitioning to plumulaceous (fluffy) at the base with a prominent downy section

Texture & Surface

Smooth and firm at the pennaceous tip, transitioning to soft and downy at the base; possesses a water-repellent surface typical of waterfowl

Key Features

Delicate fine black and white/gray vermiculations, small size, rounded shape, and soft downy base typical of a small duck's flank or scapular contour feather

Habitat

Shallow wetlands, marshes, flooded agricultural fields, ponds, and slow-moving rivers with abundant emergent vegetation

Geographic Range

Widespread across the Northern Hemisphere, breeding in northern latitudes and wintering further south across Europe, Asia, and North America

Ecological Role

Serves as an important seed disperser for aquatic plants, an integral part of wetland food webs as both consumer and prey, and acts as an ecological indicator of wetland health

Similar Species

Other small dabbling duck species such as the Mallard or Garganey, though the precise scale and fine vermiculation pattern help distinguish Eurasian Teal

Interesting Facts

Teal are exceptionally fast and agile flyers, capable of taking off vertically straight out of the water like smaller passerines rather than running along the surface

Condition Notes

Good condition, clean vane with intact barbs and a minor amount of natural wear at the very edge
