When is the best time?

Peak: 15 Nov – 15 Jan. Mid November to mid January: nest density at Palmeirinhas has averaged over 30 nests per km of beach; hatchlings from December to March

Active from 1 Oct to 15 Mar (October to March) in a typical year.

Time of day

Females come ashore after dark, mostly 21:00–03:00; hatchlings emerge at night

• Nesting: 21:00 → 03:00

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

What will you hear?

A sighting with a close-mic moment: the scraping and heavy breathing of a nesting ridley — a small turtle, a quick nest — against the Atlantic surf, and the Kitabanga patrol's low voices.

Binoculars?

No binoculars needed. A nesting ridley at arm's length on a dark beach; red torch only with the patrol.

Where to go

• Palmeirinhas – Projecto Kitabanga beaches — The long beach south of the Mussulo spit where Agostinho Neto University's Kitabanga project has patrolled since 2003. Map
• Lobito – nesting beaches around the town — Studied nesting population (October–February) on the beaches north and south of Lobito. Map
• Cabo Ledo — Beach and surf camp 120 km south of Luanda; nesting on the quieter stretches. Map

How to go on your own, and what it costs

The beaches are public (taxi or own car from Luanda to Palmeirinhas or Cabo Ledo); joining a Projecto Kitabanga patrol is by arrangement through the project (Agostinho Neto University) or the Angola Field Group. Do not approach a nesting turtle without a patrol.

Cost: Free beach; patrol by donation/arrangement, check current prices.

Free or no-guide alternative: Hatchling emergences on the public beach at Palmeirinhas or Cabo Ledo can be watched for free at night without lights; nesting females need the patrol.

Field-recording notes

Only with a Kitabanga or community patrol where one exists; on unpatrolled beaches nesting turtles are still taken, and a torch on the beach at night draws attention. Red light, rear approach, no flash. Beach driving is common on this coast and kills hatchlings — walk. Surf and wind are the bed; a low, close directional mic is the only isolation.
