Knot

Knot

The knot is a medium-sized wader that migrates to the Thames Estuary in large numbers during the winter months. In their winter plumage, knots are pale grey above and white below, while their breeding plumage features a vibrant reddish-brown chest and upperparts. These birds are highly social, often forming dense flocks that perform synchronized flights, creating a mesmerizing display. Knots feed on bivalves, worms, and other small invertebrates, which they find by probing the mudflats with their short, sturdy bills. 


The Thames Estuary is an important stopover for knots during their migration, as it provides rich feeding grounds to sustain them. While they can be harder to spot individually, their large flocks make them one of the most striking waders to observe from Southend Pier, particularly during low tide. Their sheer numbers and fascinating flock behavior make them a memorable sight for any visitor.
