Very quiet first thing. A large number of Gulls on adjacent field, nearly all Black-headed Gulls, but also a few Lesser Black-backed Gulls, Common Gulls, and two Herring Gulls. Whilst scanning through, I also noticed a bevy of twenty Red-legged Partridges at the back of the field.
The partially leucistic Blackbird was also seen in flight. As well as a white head it also has a white rump/upper-tail coverts.
Shepreth at dusk was virtually birdless apart from a few flyover Redwings.
