When is the best time?

Peak: 15 Nov – 28 Feb. Mid November to end of February

Active from 15 Oct to 15 Apr (October to April) in a typical year.

Time of day

High-tide roosts in the 2 hours around high water; dawn and dusk pirogue in the mangrove channels

• Mangrove dawn: first light → 2 h after sunrise
• Evening roost: 90 min before sunset → sunset

Depends on the tide: best around high tide. Check local tide tables.

What will you hear?

Wader and tern roosts on mangrove-fringed sandbanks at the southern end of the Bijagós system, with the mangrove's own crackle and the villages' fishing pirogues.

Binoculars?

Binoculars essential. Wader and tern roosts on sandbanks 100–300 m from the pirogue; binoculars needed, scope better.

Where to go

• Konkouré delta (Baie de Sangaréya), Dubréka — 90,000 ha Ramsar mangrove delta immediately north of Conakry: wintering Palearctic waders on the mudflats, goliath heron, hamerkop and woolly-necked stork nesting in the mangroves, bottlenose dolphins and manatee. Pirogues from Dubréka; the closest big wader site to the capital. Map
• Tristão main island (Katfoura / Kanof) — Ramsar site (1992); reached by pirogue from Kamsar or Boké. Coordinates approximate. Map
• Kamsar — Bauxite port and the departure point; loud with the mine and shipping. Map

How to go on your own, and what it costs

Bush taxi to Kamsar, then hire a pirogue (a full day) and ask village permission to stay; no park fee, but the marine protected area's community committee may ask a contribution.

Cost: Pirogue charter and village contribution — check current prices locally.

Free or no-guide alternative: The Rio Nunez estuary shore at Kamsar and Boké holds wader roosts and terns visible free from the public waterfront, without the crossing.

Field-recording notes

Thin information: the islands are a Ramsar site with a community-managed protected area but no tourism; you go with a hired pirogue and stay in a village with permission. Bauxite shipping noise near Kamsar; the outer islands are quiet. Green turtle nesting on the ocean beaches in the rains is documented but unmonitored.
