Tree Sparrows Return to the Western Isles
Thanks to warm winds, tree sparrows have begun to breed on the island of Lewis in the Scottish Western Isles for the first time in almost 25 years. RSPB Scotland officer Martin Scott came across the birds while carrying out a survey of bees. Mr Scott says that southerly winds in spring 2011 may have enticed the sparrows further north than normal. The RSPB states that the population of tree sparrows suffered a large decline in the last thirty years – but that recent data suggested that numbers may finally be on the increase again.
