The Seasonal Bird Calendar: What Migrates Through the Algarve and When

Birdwatching visitors to the Algarve tend to ask the same question: am I here at the right time? The answer changes throughout the season. This practical guide covers what may be present in the region and where to look.
How to Read This Guide
The Algarve lies on a migration route through Western Europe. Birds move through the region in both directions during the year, with some species staying to nest and others using the coast as a transit corridor. The guide below focuses on two established birdwatching areas: Ria Formosa near Faro and Tavira, and the Vicentine Coast near Odeceixe. It also identifies species associated with particular times of year.
Migration timing can vary by a week or two depending on the weather. Treat the windows below as approximate, and check recent observations at local visitor centres before choosing a site.
January to February: Wintering and Resident Species
The lagoons of Ria Formosa host overwintering birds through the coldest months.
- Greater flamingo: Present throughout the year in Ria Formosa, with larger gatherings possible on the salt pans near Tavira during winter. The Salina de Tavira observation platform provides a public viewing point accessible on foot from the town.
- Spoonbill: Regular in the lagoon channels; small groups may be visible from the Ria Formosa bird hides near Cabanas de Tavira.
- Slavonian grebe: An occasional visitor to the deeper channels of the lagoon.
- Audouin’s gull: Present along the barrier islands, including during the breeding season.
Public access: The Ria Formosa visitor centre and its surrounding trails provide access to viewing areas. Check locally for current opening hours, access conditions, and entry arrangements.
March to April: Spring Migration Begins
This is when the region transitions from wintering birds to passing migrants. March can still feel quiet; diversity generally increases during April.
- Whimbrel and curlew sandpiper: Pass through salt pans on their way north. The Tavira salt pans are a practical place to look.
- Little bittern: Arrives during spring and uses reed beds around Ria Formosa. It is often easier to detect by call at dawn from public boardwalks and hides.
- Purple heron: Arrives during spring and may remain through summer.
- Glossy ibis: Regular on passage through the lagoon during March and April.
- Osprey: Some individuals overwinter, while others pass through during spring. Sightings are possible along the Vicentine Coast.
For spring migration: Late April generally offers more variety than early March. The salt pans near Tavira and the channels near Cabanas de Tavira are practical places to start.
May to June: Breeding Season and High Diversity
This window overlaps with the main visitor season. Bird diversity can be high, but nesting species may be harder to observe than birds moving through on passage.
- Kentish plover: Nests on barrier-island beaches. Look for them on Culatra and Faro Island, and give nesting birds plenty of space.
- Little tern: Nests on flat ground near salt pans and beaches. It is generally present from May to July.
- Montagu’s harrier: Uses open agricultural landscapes farther north, including areas around Cercal do Alentejo.
- European roller: May be encountered inland during the spring migration period. The hills around São Brás de Alportel provide open countryside in which to look.
- Western Algarve woodland and scrub birds: The Monchique hills and the Vicentine Coast protected area offer habitats different from the coastal lagoons, with species such as azure-winged magpie and short-toed treecreeper.
July to August: Less Migration Activity
Fewer migrating species pass through during summer. This period is more suitable for observing resident species, breeding birds, and occasional seabirds from public coastal viewpoints.
- Scopoli’s shearwater and Cory’s shearwater: May sometimes be visible from coastal headlands such as Ponta da Piedade and Cabo de São Vicente, although distant birds can be difficult to identify from shore.
- Greater flamingo: Remains present on the salt pans, usually in smaller numbers than during winter.
- Bee-eater: Present from spring through summer. Flocks may be visible over open farmland around Tavira, Silves, and Portimão.
September to October: Autumn Migration
Autumn is a reliable birdwatching window. Southbound migration brings waders, terns, and raptors through the region.
- Waders, including curlew, whimbrel, greenshank, and black-winged stilt: Passage through the salt pans increases during September. The Tavira salt pans provide accessible viewing opportunities.
- Spoonbill: Post-breeding flocks may gather at Ria Formosa during September.
- Raptors: Honey buzzard, booted eagle, and short-toed eagle may pass through the western Algarve during September. Public cliff overlooks near Praia do Monte Clérigo provide a place to watch for movement along the coast.
- Greater flamingo: Numbers begin to rise as wintering birds return.
- Audouin’s gull: Post-breeding movement occurs along the coast, with birds visible around the barrier islands.
September is a practical month for a birdwatching visit. It combines wader passage at Ria Formosa with raptor movement in the western Algarve.
November to December: Return to Winter Conditions
Flamingo numbers rise during the winter period, while a range of waders remains present through December. The lagoons generally become quieter after the autumn migration period.

| September | Tavira salt pans and Praia do Monte Clérigo | Waders, raptors, and spoonbill flocks | Very high |
| October | Ria Formosa | Returning flamingos and continued passage | High |
| November | Tavira salt pans | Wintering flamingos | Moderate |
| December | Ria Formosa | Wintering species settling | Low to moderate |
Practical Notes
- Timing: Visit reed beds around dawn when calling birds are easier to detect. Salt pans are generally easier to scan once there is enough daylight to distinguish distant birds.
- Equipment: A spotting scope is useful for scanning the broad channels of Ria Formosa. Binoculars remain suitable for trails, woodland, farmland, and closer birds.
- Salina de Tavira: Use designated public paths and viewing areas, and check current access conditions before visiting.
- Barrier island access: Check current public ferry routes, timetables, fares, and weather conditions locally before departing. Bring water and other essentials, and avoid marked nesting areas.
