Mallard Iridescence

The mallard is so common in the UK, such a successful survivor, that I often overlook it when taking photographs. But it really is a rather beautiful bird.

Particularly striking is the iridescence (surfaces that appear to gradually change colour as the angle of view or the angle of illumination changes) in the head and neck of the male. This was particularly apparent at WWT Slimbridge recently, with the colours on full show for the breeding season, and the sun still quite low on an April afternoon.

The male appears sometimes green, sometime blue, and colours in between.

Because of the easy availability of food, mallards are very tame at Slimbridge, so you can get close. These shots are of the female, also attractive but more by patterning than by colour.

  1. You’re right, they are beautiful – and plentiful. We have a pair swimming around in our backyard at the moment; we back onto the St. John River and we’re at the height (I hope) of a record spring flood.
