# Eurasian Oystercatcher

*Haematopus ostralegus*

Individuals specialize in one of two feeding methods: 'stabbers' hammer through shells, while 'heavers' pry them open using the bill as a lever.

- **Taxonomy:** Animalia › Chordata › Aves › Charadriiformes › Haematopodidae › Haematopus
- **IUCN Red List status:** Near Threatened
- **Population trend:** decreasing
- **Biome:** wetland
- **Habitat:** Coastal mudflats, estuaries, sandy and shingly beaches, and occasionally inland damp grasslands.
- **Diet:** Specializes in bivalve mollusks like mussels and cockles, as well as earthworms and crustaceans.
- **Range:** Europe, Central Asia, East Asia, North Africa
- **Size:** 40-45 cm in length with a wingspan of 80-86 cm.
- **Lifespan:** 12-15 years on average, though some individuals have lived over 35 years.
- **Active:** diurnal
- **Threats:** Overfishing of shellfish stocks, habitat loss due to coastal development, and disturbance from recreational activities.
- **Safe to approach?:** Harmless but highly vocal. They are ground-nesters; if a bird circles you while screaming 'kleep', you are too close to its nest. Maintain a distance of at least 50 meters and watch your step on shingle beaches to avoid crushing camouflaged eggs. No medical risk to humans.
