18-7-2018 ALBUFERA, VALENCIA - EUROPEAN TURTLE DOVE (Sternula albifrons)


Populations of turtle dove are in rapid decline across Europe and this species has red list conservation status globally. In the United Kingdom its numbers have declined by 93% since 1994 and across Europe numbers fell by 78% 1980–2013.

Environmentalist groups have said that the decline of turtle doves in Europe is partly because changed farming practices mean that the weed seeds and shoots on which it feeds, especially fumitory, are scarcer, and partly due to shooting of birds in Mediterranean countries. According to a 2001 study cited by the European Commission, between two and four million birds are shot annually in Malta, Cyprus, France, Italy, Spain and Greece.Environmentalists have described spring hunting in Malta as particularly problematic as it is the only country with an EU derogation to shoot birds during their spring migration to breeding grounds.


According to a 2007 study by the European Commission, four currently identifiable potential threats to the turtle dove are  habitat loss/modification (medium to low impact),  droughts and climate change (mostly unknown but likely low impact),  hunting (partly unknown but overall medium impact), and  competition with the collared dove (unknown impact). The British Trust for Ornithology has also highlighted Trichomonosis parasite as a threat to the turtle dove.

16-7-2018 VILLALONGA RESERVOIR, VALENCIA - BROAD SCARLET DRAGONFLY (MALE) (Crocothemis erythraea)


The scarlet dragonfly (Crocothemis erythraea) is a species of dragonfly in the family Libellulidae. Its common names include broad scarlet, common scarlet-darter, and scarlet darter.

The scarlet dragonfly is a common species in southern Europe and throughout Africa. It also occurs across western Asia as far as southern China. It is a very rare vagrant in Britain. Its first record in the country was at Hayle Kimbro Pool, The Lizard, Cornwall, on 7 August 1995. Since then there have been a few further records at scattered locations throughout Britain.


A wide range of both running and standing waters, except those that are shaded. Adults may be found some distance from water in habitats ranging from desert to open woodland; absent from dense forest.

Crocothemis erythraea can reach a length of 33–44 millimetres (1.3–1.7 in). These dragonflies haves a flattened and rather broad abdomen. The adult male scarlet dragonfly has a bright scarlet red, widened abdomen, with small amber patches at the bases of the hindwings. Also the veins on the leading edges of the wings are red. Females and immatures are yellow-brown and have a conspicuous pale stripe along the top of the thorax.

15-7-2018 L'ORXA, VALENCIA - COMMON HOUSE MARTIN (Delichon urbicum)


The Western House Martin (Delichon urbicum), sometimes known as the Common House Martin, is a migratory passerine bird belonging to the swallow family. It is characterized by a blue head and upperparts, a distinctive white rump, and pure white underparts. This species exhibits sexual dimorphism, with both sexes appearing similar, and juveniles displaying a sooty black coloration with white-tipped wing coverts and quills.

Adults measure approximately 13 cm in length, with a wingspan ranging from 26 to 29 cm and an average weight of 18.3 grams. They possess brown eyes, a small black bill, and pink toes and exposed leg parts. The white rump and underparts are particularly noticeable in flight, aiding in distinguishing them from other swallows.

The Western House Martin favors open country with low vegetation, such as pastures, meadows, and farmland, often near water. It is also found in urban areas and can nest in city centers if air quality permits.

This bird breeds across Europe, North Africa, and the Palearctic, migrating to sub-Saharan Africa and tropical Asia for the winter. It is a broad-front migrant, traveling during daylight and feeding on insects in flight.


The Western House Martin is a social bird, often breeding colonially with nests built in close proximity. It is known for its aerial agility, which it uses to evade predators such as the Eurasian Hobby.

The male's song is a soft twitter of melodious chirps, while the contact call is a hard "chirrrp." The alarm call is a shrill "tseep."

Nests are constructed from mud pellets under eaves or similar overhangs on buildings, usually in colonies. The species is known to produce two broods per year, with four to five white eggs per brood. Juveniles fledge after 22 to 32 days and are fed by parents for about a week thereafter.

The Western House Martin can be confused with the Asian House Martin (D. dasypus) and the Nepal House Martin (D. nipalense), but it is the only one with a pure white rump and underparts.


The diet consists primarily of insects caught in flight, with a preference for flies and aphids. Hunting typically occurs within 450 meters of the nest and often near open ground or water.

The Western House Martin is classified as Least Concern by the IUCN, with an extensive range and large population. However, there are indications of population fluctuations and declines in certain regions, attributed to factors such as weather, pesticides, and competition for nesting sites.

7-7-2018 TABLAS DE DAIMIEL, LA MANCHA - EURASIAN LINNET (FEMALE) (Linaria cannabina)


The common linnet, Linaria cannabina, is a small, slender finch with a fondness for seeds, particularly those of hemp and flax. The male, in his breeding plumage, is distinguished by a grey nape, a striking red head-patch, and a red breast, while the female and juveniles are more subdued in coloration with white underparts and buff-streaked breasts.

When identifying the common linnet, look for the long tail and the contrast between the brown upper parts and the sullied white throat. The bill is grey, and the male's red accents are most vibrant during the breeding season.

This species prefers open land with dense shrubbery for breeding, including heathlands and gardens.

The common linnet has a wide range across Europe, the western Palearctic, and North Africa. It is partially migratory, with many birds from the east and north moving southward or toward coastal areas during the non-breeding season.

Outside of breeding season, common linnets may gather in large flocks, occasionally mixing with other finch species. They are known for their delightful song, which features rapid trills and twitters. Breeding involves nest building within bushes and laying clutches of four to seven eggs.

7-7-2018 TABLAS DE DAIMIEL, LA MANCHA - GREYLAG GOOSE (Anser anser)


The Greylag Goose (Anser anser) is a large and robust member of the waterfowl family Anatidae, easily recognized by its mottled and barred grey and white plumage. It boasts an orange beak, pink legs, and a sizeable stature, measuring between 74 and 91 centimeters in length and weighing an average of 3.3 kilograms. This species is the progenitor of most domestic goose breeds and exhibits a wide distribution across Europe and Asia.

Adult Greylag Geese have a rotund body, a thick and long neck, and a large head and bill. Their legs and feet are pink, and their bill is orange or pink with a white or brown nail. The wingspan ranges from 147 to 180 centimeters. Males are typically larger than females, and the eastern subspecies rubirostris is larger than the nominate subspecies. The plumage is greyish brown with a darker head and paler underparts, with black spotting that varies among individuals. Juveniles can be identified by their lack of black speckling and greyish legs.


Greylag Geese breed in a variety of wetland habitats, including moorlands, marshes, lakes, and coastal islands. They prefer areas with dense vegetation for cover. In winter, they occupy semi-aquatic habitats such as estuaries, marshes, flooded fields, and agricultural lands.

The Greylag Goose has a Palearctic distribution, with the western subspecies breeding from Iceland to central Europe and the eastern subspecies from Romania to northeastern China. Northern populations often migrate southwards to spend the winter in warmer regions, while many populations are resident year-round.

7-7-2018 TABLAS DE DAIMIEL, LA MANCHA - WHITE HEADED DUCK (FEMALE) (Oxyura leucocephala)


The White-headed Duck, Oxyura leucocephala, presents a striking figure with its distinctive plumage and stout build. Males are adorned with a white head contrasted by a black crown, a blue bill, and a body cloaked in shades of reddish-grey. Females, on the other hand, exhibit a more subdued palette with a dark bill and less vibrant colouring.

Upon encountering this species, one can identify the male by its white head, black cap, and neck, and a blue bill, while the female can be recognized by her grey-brown body, white face, and darker bill and cap. These ducks measure between 43–48 cm in length and weigh approximately 580–750 g.

The White-headed Duck favors lakes with open water and dense vegetation along the margins, which provide essential cover and nesting sites. These habitats include natural lakes and ponds as well as man-made water bodies.

7-7-2018 TABLAS DE DAIMIEL, LA MANCHA - RUFF (Calidris pugnax)


The Ruff, Calidris pugnax, is a medium-sized wading bird known for its remarkable breeding plumage and sexual dimorphism. Males, significantly larger than females, boast ornate ruffs and head tufts in a variety of colors during the breeding season. Females, referred to as "reeves," are more subdued in coloration. The species exhibits a pot-bellied profile, with a small head and long neck, and displays a distinctive flight pattern with a slow wingbeat.

In breeding plumage, males are unmistakable with their bright ruffs and head tufts, which can be black, chestnut, or white. Females and non-breeding males are more cryptic, with grey-brown upperparts and mainly white underparts. Juveniles resemble non-breeding adults but have a buff tinge to their plumage. The ruff's long legs vary in color from greenish in juveniles to pink or orange in adults.


Ruffs breed in marshes and wet meadows across northern Eurasia. They prefer hummocky marshes and deltas with shallow water for feeding and dry areas with sedge or low scrub for nesting.

This migratory species breeds from Scandinavia and Great Britain to the Pacific, with the largest numbers in Russia and Scandinavia. In winter, they are found in southern and western Europe, Africa, southern Asia, and parts of Australia.


Ruffs are highly gregarious, especially during migration when they form large flocks. Males display at leks, with territorial males occupying small areas and satellite males attempting to mate within these territories. A third, rare male type mimics females to gain mating opportunities.

The ruff is generally silent, but during display, a soft "gue-gue-gue" may be heard.


Females lay four eggs in a well-hidden ground nest and incubate them alone. Chicks are mobile soon after hatching and are reared solely by the female. Males leave the breeding grounds early in the season.

Juvenile sharp-tailed sandpipers and buff-breasted sandpipers can be confused with juvenile ruffs but differ in size, shape, and plumage details.


Ruffs feed on insects, especially during the breeding season, and consume plant material, including rice and maize, during migration and winter. They forage in wet grassland and soft mud, probing or searching by sight for edible items.

Globally, the ruff is classified as "Least Concern" due to its large breeding numbers in Scandinavia and the Arctic. However, European populations are contracting and are listed as "Near Threatened" due to habitat loss and over-hunting. The species is protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).
