This one has a loud, strident whistle which I can hear.
I used to have an electric one which whistled as it switched itself off. Unfortunately the element gave up. When I replaced it the new one tainted the water with a strong 'plastic' taste, even after several boilings, so I went back to the type I could use on a gas ring.
The second copper of the week - a Small Copper Butterfly.


Since the very cold blast we suffered earlier in the year I haven't seen many butterflies, let alone those which stayed still long enough to photograph.
