Photo tip
Use a low angle at water level for reflections. In February–May, watch a pair from a bankside seat in soft early light with a 400–500 mm lens, and be ready for the weed dance.
Be a good naturalist
Keep well back from nests, especially from boats: grebe nests float at the water's edge and wash can swamp them. Don't approach courting or nesting pairs.
The law
Protected under Wildlife and Countryside Act 1981.
