Spring migration really got going this week, with the reserve's first blackcap, several common sandpipers and a few more house martins among the large flocks of swallows and sand martins. But the highlights were the raptors, with Osprey seen most days, Red Kite, Peregrine, Kestrel and Short-eared Owl.
Several of the Ospreys were photographed and shared on social media, enabling Rob Hughes to spot that at least two - and quite possibly more - birds were involved. Here's just one of the images, of an Osprey hovering over the estuary, by Matthew Boa.
