Sampling Methods

The band census method is applied along the National Park beach in Southeast-Northwest direction. Transect is conducted at constant speed (10-20 km/h) during the morning low tide. This allows higher visibility (sunlight coming from the back). Stops were made when necessary (counting or identification). Wind speed (6 categories from calm to gale), wind direction, sky conditions (6 categories from sunny to rainy), and sea conditions (6 categories from calm to very rough).

Study Extent Protected in 1968, Doñana National Park (537 km2) is a UNESCO Biosphere Reserve, a Ramsar Site and a Natural World Heritage Site. The site contains 25 km-long dune ecosystem and its respective shoreline along which the band census method was applied monthly during one year.
Quality Control Each identification (scientific name) is matched against the GBIF Backbone Taxonomy as a quality control to make sure that each identification is correct.

Method step description:

  1. Conduct 29km transect driving in 4x4 vehicle at constant speed (10-20 km/h) monthly between days 10 and 20 looking for the best morning low tide.
  2. Divide transect into three sections 13.5km (CAMA), 7.5km (MAZA), and 8km (ZACA) by using the easily recognisable reference points of Zalabar and Carbonero watchtowers. CAMA means Carbonero-Matalascañas (the beach resort), MAZA means Malandar-Zalabar (Malandar is the name of the point where the river joins the ocean), and ZACA means Zalabar-Carbonero (the two watchtowers). Considering that maximum width of the beach is around 300m, these transects cover 4 km2, 2.1 km2, and 2.4 km2, respectively
  3. For each section (of transect), for each bird (non Passerines and crow) species observed, record its name and number of individuals counted, stopping the car when necessary.
  4. For each section (of transect), record wind speed (6 categories from calm to gale), wind direction, sky conditions (6 categories from sunny to rainy), and sea conditions (6 categories from calm to very rough).
  5. Match each identification (scientific name) against the GBIF Backbone Taxonomy as a quality control, and augment each identification with the matching species' higher taxonomy.
