There are unconfirmed reports of an extraordinarily rare wild nesting pair of Caeli Albens at an undisclosed location near to Dorking, Surrey. This is the first such sighting in the UK since 1932. Although there is considerable scientific interest in how the non-native species came to settle in the area, there is also concern about the potential impact on native fauna. Paul Walton of the RSPB said
The impact of invasive non-native species is one of the principal drivers of global biodiversity loss and environmental degradation, but is also one of the least understood and appreciated. Therefore, developing an appropriate response is a very significant challenge to policy makers.
Despite the longer term concerns, the opportunity to observe these magnificent creatures close up is bound to add considerably to the currently sparse information about their behaviour in the wild.
