Had a check for passage waders today, but I ended up stint-less and not getting wood.
However, a northbound flock of 7 black-tailed godwits was a small compensation. They scoped out Freeman's Pools but resisted its charms and headed on.
Swifts and house martins were in good supply, with around 45 and 15 respectively.
It's tempting to think that they're all foragers from nearby civilisation (and the Marsh estate), but two fly-through sand martins were evidence that some passage is still ongoing.
