What will you hear?
A big gull and tern roost — royal and Caspian tern screams, slender-billed and Audouin's gulls, knot and godwit flocks — beside one of West Africa's busiest fishing ports; the iron-ore train and the harbour are the backdrop, the Baie de l'Étoile north of town is the quiet, dolphin-haunted end.
Binoculars?
Telescope recommended. The bay is 10 km wide — roosts are hundreds of metres out on the sandbanks; a scope from the shore road, binoculars for the dolphins.
Where to go
- Baie de l'Étoile — Shallow bay and marine reserve 12 km north of town inside the peninsula: seagrass, sandbanks, flamingos, tern roosts and the site's Atlantic humpback dolphin records. Track off the Nouakchott road. Map
- Cansado bay — Sheltered bay south of the city by the SNIM ore port: wader and gull roosts on the flats at high water. Public shore road. Map
- Nouadhibou fishing harbour and town shore — The artisanal port and fish market draw thousands of gulls and terns; the taxi stand for Cansado is on the Cheikh Zayed road. Map
How to go on your own, and what it costs
Nouadhibou has flights and the N2 from Nouakchott (about 5 h). Taxis to Cansado (south) and along the peninsula road north to the Baie de l'Étoile turn-off; the shore is public. Check tides at Nouadhibou. Combine with the monk seals at Cap Blanc (separate entry).
Cost: Free (2026); taxi to Cansado or the Étoile turn-off a few hundred MRU (check current prices).
Field-recording notes
Port, naval base, ore terminal and the border with the Dakhla–Western Sahara zone running down the peninsula: photograph and record only the birds, stay on public roads and beaches, and expect to be asked what you are doing (keep your passport and a polite explanation ready). The Baie de l'Étoile is the one quiet place — wind and the surf on the ocean side are the noise. Hydrophone off the Étoile sandbanks on a calm high tide for Sousa teuszii (unrecorded here). Cold wind in winter; no permits for the bay, PNBA permit if you continue south into the park at Cap Blanc's satellite reserve.
