American Wigeon on the Kamo River

　Having finished an early morning request for travel support, I was strolling along the Kamo River when I spotted a particularly striking cream-coloured head amidst the usual flock of Eurasian wigeons. It was an American Wigeon, which breeds in North America and winters in Mexico and northern South America.

　Japan lies outside its breeding range, so it was quite a rare bird when I was a child, but sightings have increased recently. Still, it remains unusual. Upon checking, I learned it has been wintering on the Kamogawa since last year.

　The beauty of the Kamogawa is that even rare birds can be observed at a truly accessible distance. I hadn’t brought my camera as I was on my way home from work, but even with my smartphone, I could get this close.

　Ducks are particularly prone to hybridisation between species. In Japan, hybrids between this American Wigeon and the Eurasian wigeon are frequently seen. In North America, where Eurasian wigeons are absent, hybrids with Mallards, Gadwalls, Northern Shovelers, and Green-winged teals  have also been confirmed. It’s a truly remarkable bird.
