A Tale of Two Ducks

Back to Arnot Hill Park and the duck pond again, with two interesting ducks.

One is the Mandarin drake. He wasn’t about last visit, and on the visit before that it was so dull I couldn’t get a good shot.

We have a population of around 2,300 breeding pairs in the UK, with more in Dublin and mainland Europe. In winter there can be as many as 7,000 individuals, including migrants from Europe. All were introduced, either deliberately or from accidental escapes. ┬áIn its normal range habitat destruction has reduced the population to around a 1,000 in China, and about the same in Russia. The only stable population is Japan, with 5,000 pairs. It is listed as “declining” worldwide, but is still a species of Least Concern.

The one I saw today, though small, is quite capable of holding his own against Coots and Mallards, two species that are currently getting a bit lively as the breeding season approaches.

 

The other duck caught my eye amongst the various Mallard hybrids is a pleasantly coloured individual with a longish tail that resembles a Pintail. The shape of the neck ring, from certain angles, also resembles a Pintail.

I looked up hybrid ducks and found several records that look like this, plus an analysis of how they happen. Mallards have a bit of a reputation for overly enthusiastic mating and this is one of the results.

The photograph of the duck lacking head was a mistake, but is the only one showing the green speculum which is a feature of this cross-breed.

It’s amazing what you can learn from looking at a duck pond.
