An illustrated planning exercise

The shore
has a schedule.

As the water falls, a feeding ground appears. Follow a sample tide and meet the birds working its changing edges.

The flats are open.

Near low tide, broad areas of mud are exposed. Scan slowly for feeding flocks, keeping your distance from the water’s edge.

Dunlin

Small waders probe soft mud with slightly downcurved bills, often moving in busy groups.

Wide feeding area exposed

Oystercatcher

A sturdy, orange-red bill and bold black-and-white body stand out around shellfish-rich shores.

Shellfish beds accessible

Avocet

Look for the slender upcurved bill sweeping side to side through shallow water.

Shallow channels available

This is a fictional tide curve for learning, not a navigation forecast. Real tides vary by location and date. Use a local tide service and observe from established paths; mudflats and rising water can be hazardous.
