Eurasian Swift (J. Sanz)I'm really into Swifts and I'm quite alarmed about their demise in numbers over the years - down by 47% according to figures released by the RSPB. Over the years, I have actually noticed a slump in numbers. Far less birds are to be found swooping low over the grassland at Wormwood Scrubs than in previous years. I remember tons more Swifts flying around on hot summer days when I was a teenager at school.
And the reason for the decline? A lack of nest sites. We are building structures without the crevices that these birds so love. I just hope that the architects who design new buildings wake up to the opportunity that they have to help hole nesters survive and prosper.
They have enough dangers to face on their long migrations. Let's get out there and make some holes!
