A brown-feathered Eurasian teal was recently spotted at the East Lake of Chenshan Botanical Garden in Songjiang District.

This unexpected visitor caught people’s attention when Botanic Garden staff were scavenging weeds on the lake and noticed a metallic green wing-flapping duck, which was later identified as a rare teal.

The small duck species lives in different parts of the northern hemisphere and is usually less than 30 centimeters long. It gets its name “green wing” from the feathered area on its fenders that reflects a metallic green sheen, sometimes referred to as “side mirrors”.

Female Eurasian teals have darker bodies, while males have green stripes extending from their eyes, making them more beautiful and eye-catching.

In recent years the Botanical Garden has been visited by wild ducks such as gadwalls and tufted ducks, but this is the first time a teal has been sighted there.

These ducks have seasonal migration habits and typically migrate north from their southern wintering grounds each spring and return south in September or October. The Yangtze River estuary is one of their wintering grounds.
