Unseasonal weather alters bird migration patterns
Unpredictable weather has altered bird migration patterns, with many arriving in parts of the UK weeks earlier than expected, say experts.
The National Wetland Centre in Llanelli said 800 curlews, not normally seen until late August, were early arrivals.
It is believed that the reason for the birds' early arrival might be that some of them failed to breed in other parts of the world.
