Species 1

Little Tern

Very small, fast flying, slender tern with pointed wings, forked tail and dives frequently to capture its prey in the water. When perched, its legs and bill are yellow, the latter has a black tip. Its head has a black hooded patch, but with a white forehead, from which it gets its scientific name. Its back is grey and the rest of the body white.

Scientific name

Sternula albifrons

Family 2

Laridae

Taxonomic Affinity Group 3

Gulls and Terns

Phenology 4

.This bird, which is classified as “near threatened” due to the vulnerability of its nesting populations, is a typical summer bird, which can be seen during the summer months. The phenological behaviour in Roquetas de Mar is the same.

The graph represents the probability of seeing a species during the year, grouped into months. The vertical axis indicates the percentage value. Each of the bars expresses its value. The horizontal axis represents the months: I = January, II = February, III = March, IV = April, V = May, VI = June, VII = July, VIII = August, IX = September, X = October, XI = November and XII = December.

Observation recommendations

In the ‘Salinas Nuevas’, ‘Ribera de la Algaida’ and ‘Cerrillos’ they are easy to see on their perches, while in the ‘Salinas Viejas’ and along the coast they are usually seen when feeding. They are common to our beaches, searching for prey and diving not far from the surf line.

Notes

[1] The names used are from the list of birds of Spain, drawn up by SEO/BirdLife and updated to 2019 (https://seo.org/listaavesdeespana/). The reference is: Rouco, M., Copete, J.

[2] The taxonomic family to which it belongs is indicated.

[3] Traditionally, waterbirds have been grouped according to their taxonomy or “taxonomic affinity”, i.e., when some birds coincide in certain features that allow them to be classified scientifically, but without leaving the rigour of science, they are put together in these groups so that they can be easily recognised. These groups are the following: Greves (belonging to the Podicipedae family), Herons and Similar (includes the families: Ardeidae -Herons- Ciconiidae -Storks- and Threskiornithidae -Ibises and spoonbills-), Ducks (the whole Anatidae family), Coots and Similar (the family Rallidae corresponding to Rails, Gallinules and Coots), Cranes (also with only one family, the Gruidae), Waders , a heterogeneous group, the most diverse of this classification, includes the families Burhinidae (Stone-curlews), Haematopodidae (Oystercather), Recurvirostridade (Avocets and Stilts), Glareolidae (Pranticole), Charadriidadea (Plovers), Scolapacidae and finally Gulls and Similar (the recently unified family Laridae, i.e. Gulls and Terns).

[4] Phenology studies the relationship between the cycles of living beings and meteorological factors, and in our latitude these factors manifest themselves as variations throughout the year, thus relating the seasons to the birds’ cycles (breeding, migratory journeys, etc.) The graph shows the probability of seeing a bird depending on the month. It uses data from 48 bird censuses carried out between October 2016 and September 2018. The method used is that of a census route with sampling stations, with a total count on the sheet of water.
