When is the best time?

• Peak 1: 15 Aug – 30 Sep — Mid August to September: autumn passage, over half a million soaring birds in a season
• Peak 2: 1 Mar – 30 Apr — March to April: spring return — black kites and short-toed eagles in March, honey buzzards from late April into May

Active from 15 Feb to 15 Nov (February to November) in a typical year.

Time of day

Storks and bee-eaters move from early morning; raptors once thermals build, roughly 10:00–17:00; the stork pre-roost at Los Lances gathers in the 2 h before sunset.

• Storks and bee-eaters: sunrise → 10:00
• Raptor passage: 10:00 → 17:00
• Stork pre-roost: 2 h before sunset → sunset

What will you hear?

Mostly visual — kettles of thousands — but bee-eater flocks pour over calling all day, honey buzzards pass at head height in a levante, and the stork pre-roost at Los Lances is a bill-clattering crowd.

Binoculars?

Telescope recommended. Kettles high over the Strait; binoculars essential, a scope for eagles and the stork roost on Los Lances.

Where to go

How to go on your own, and what it costs

Cazalla observatory: N-340 km 87, free car park and viewpoint, Fundación Migres volunteers counting daily in autumn. Algarrobo: signed from the N-340 near Punta Paloma. Punta Carnero: the road from Algeciras/Getares. Los Lances: free beach reserve with a boardwalk from the Tarifa side.

Cost: Free.

Field-recording notes

The wind decides everything: easterly 'levante' pushes birds low over Tarifa itself; a westerly 'poniente' shifts them to Algeciras. Hundreds of wind turbines line the ridges — a constant broadband hum at the observatories. The N-340 runs past every viewpoint. For sound, target the bee-eaters and the stork roost rather than the raptors.
