March is good time of year to be looking out for Hares, as they are particularly active, due to their "boxing" behaviour, which gives them the name of the "Mad March Hare." This is related to courtship and is actually where the female fights off unwanted attentions from males.
They are much larger than rabbits with long black-tipped ears and also have very powerful, long hind legs. They can grow up to 70cm and weigh between 3 - 4 kgs.
Commonly found on farmland in lowland Britain, they spend much of their day sheltering in depressions in long grass, known as a form.
The brown hare's population has seen one of the largest declines for a British mammal species, second only to the water vole. The main reason for this decline is changes in farming practices.
There is little legal protection for this species, but it does have a Biodiversity Action Plan written for it.
