Whilst out bagging Cetti's at Uskmouth, I snuck up on a randy group of Pochard doing their thing (well who wouldn't?), surely the most acoustically entertaining Aythya in the world. If all you expect of Pochard is the 'grrr-grrr-grrr' flight call, click on the snippet below and prepare for 'wi-wi-wi' whistles and nasal wheezes (with and without 'ricochets') courtesy of displaying males; and the odd soft cluck or two (not sure which sex is emitting this, answers on a postcard/comment). As if that's not enough, there is also a pretty picture to show you what you're hearing from roughly second 17 to 20. PS. Apologies for the wind/anthropogenic background rumble, I had to leave it in or lose some low frequency elements of Poch.
