Otters

Every year, otters are seen in the Lambrok right the way up into Southwick village. They hunt swan mussels in the stream in the reserve and fish in the moat at Southwick Court. Here are some things you may not have known about this species.

The winter thrushes

Fieldfare (Turdus pilarus) and redwing (Turdus musicus), migratory thrushes from mainland Europe, are common winter visitors to the park. They are easily confused; here is a video to help you distinguish the two species.

Migration changes

Analysis of records kept since 1964 has found that some species of European migratory birds are spending up to 60 days less each year in their sub-Saharan wintering grounds. Over the most recent 27-year period, migratory birds, including the whitethroats commonly seen in our reserve, were found to have increased their time in Europe by an average of 16 days. It has even been suggested that some species may stop flying south for the winter altogether.

Earthworms

Charles Darwin calculated that there would be 53,000 earthworms in an acre of soil. That number has been adjusted upwards over the years and at the moment stands anywhere between 500,000 and a million. The reserve covers about 140 acres so, even at the lowest of modern estimates, there are 70 million earthworms in the park.

Kingfisher

This is the time of year when the summer’s brood of fledgling kingfishers are driven away from the home territory by their parents, and set off to look for good fishing grounds of their own.
