More about swimming hares

Nick Carter’s observation of a swimming hare, White Admiral 64, reminded me of September 2001 when I was given permission to walk the whole of the long shingle spit that includes Orford Ness. I started at North Weir Point opposite Shingle Street and eventually ended up at Slaughden. During this day’s walk I counted 24 hares, easily my highest day total. I tried very hard not to count any twice and consider this an accurate number. Obviously these hares had to cross from the mainland at some time. A friend has told me that in his younger and fitter days he actually allowed the tidal flow to carry him across to the shingle spit with a minimum of effort, but I imagine a fine sense of judgement. Perhaps the pioneer hares did the same. The more I thought about it, the more I concluded that this was a good habitat for hares. There are few predators, including humans, there is an abundance of well established mats of vegetation to eat, enough dew and moisture to drink and, by using the troughs and hollows between the storm-created shingle banks, protection from extremes of weather in what is otherwise a very exposed habitat.

Scratching the surface

While walking along the beach at Shingle Street, on Friday 26th May 2006, we noticed a largish animal, which ran over the crest of the beach and headed towards the sea. We were some way off to identify positively what type of creature it was, but having seen a brown hare (Lepus europaeus) a little way back we suspected that it might have been of that species. As far as we are aware, it did not enter the sea. A little while later, an animal was seen on the beach, some ten metres away from the sea. It was clearly a hare. What it was doing on a beach we were unsure of, until it turned on its back and began to writhe around. Initially we were puzzled by this behaviour but then suspected that it may have been scratching its back and that the shingle on the beach was the most effective ‘tool’ with which to do so. It may have been attempting to rid itself of its winter pelage. Harris et al (1991) state that the spring moult commences in March and is usually finished by June and that the moult begins at the nape, mid-back and head and spreads downwards and backwards. The weather in spring had been particularly cool in March and snow had fallen in the south-east of England on 9th and 10th of April. This was a month in which no maximum was recorded above 20°C since 1986 (Branson, 2006), so perhaps the inclement weather delayed the moult a little? Hares in southern Britain would probably experience their moult before those of the north.

Autumn flowering Horse Chestnut

Whilst driving along the A1214 London Road in Ipswich near Chantry Park on September 27th
I noticed two Horse Chestnut trees on the central reservation with some fresh new leaves and flowers. Otherwise they were almost completely leafless. I have been told that in eastern Europe, where the horse chestnut leaf miner Cameraria ohridella has been around for a long time, trees that are defoliated early in the year will attempt to recover be producing a second crop of leaves and flowers, presumably that is the case here. I gather that this further weakens the tree and it soon dies. It will be interesting to see what these trees do next Spring.
