Swifts : fast & low : RSPB Otmoor

The common swift (Apus apus) is probably one of the most challenging #birds I've tried to film; not surprising given their amazing speed and manoeuvrability.
I had a great time attempting to follow these birds as they hunted insects low over the lake and reedbeds at RSPB Otmoor (Oxfordshire, UK) recently. The vast majority of the footage ended up on the digital equivalent of the cutting room floor, but I was pleased that a few clips were - whilst not exactly top quality - at least usable as a demonstration of the birds' little-seen feeding behaviour.
Filmed on an #iPhoneXs attached to a spotting-scope (technique known commonly as phonescoping).
