Mating Behaviour (4 of 5)
There were a number of Red-breasted Mergansers in Portland Harbour this weekend. Towards the end of the day, this pair separated from the others and starting to exhibit behaviour that I had not seen before. The male courtship is often seen at this time of year, but this was different, in that the female was looking very submissive with her tail pointing up. Typical mating behaviour but surely not in December. Anyway as this series of images show it was clear was a mating attempt or pair bonding.
