29-7-2019 ISABEL CATOLICA PARQUE GIJON, ASTURIAS - EURASIAN COOT (Fulica atra)


The Eurasian coot, Fulica atra, also known as the common coot or Australian coot, is a distinctive waterbird with a slaty-black body, a glossy black head, and a striking white bill topped with a white frontal shield. This bird is a member of the Rallidae family, which includes rails and crakes. Both sexes exhibit similar plumage, making them indistinguishable in the field.

Adult Eurasian coots measure 36–38 cm in length with a wingspan of 70–80 cm. Males are slightly heavier than females, weighing around 890 g compared to the females' 750 g. The species is characterized by its white bill and frontal shield, which contrast sharply with its all-black body. Juveniles are paler with a whitish breast and lack the facial shield, which develops fully by one year of age.

29-7-2019 ISABEL CATOLICA PARQUE GIJON, ASTURIAS - YELLOW LEGGED GULL (JUVENILE) (Larus michahellis)


The yellow-legged gull is a large gull, though the size does vary, with the smallest females being scarcely larger than a common gull and the largest males being roughly the size of a great black-backed gull. They range in length from 52 to 68 cm (20 to 27 in) in total length, from 120 to 155 cm (47 to 61 in) in wingspan and from 550 to 1,600 g (1.21 to 3.53 lb) in weight. Among standard measurements, the wing chord is 40.8 to 47.2 cm (16.1 to 18.6 in), the bill is 4.6 to 6 cm (1.8 to 2.4 in) and the tarsus is 5.6 to 7.5 cm (2.2 to 3.0 in). Adults are externally similar to herring gulls but have yellow legs. They have a grey back, slightly darker than herring gulls but lighter than lesser black-backed gulls. They are much whiter-headed in autumn, and have more extensively black wing tips with few white spots, just as lesser black-backed. They have a red spot on the bill as adults, like the entire complex. There is a red ring around the eye like in the lesser black-backed gull but unlike in the herring gull which has a dark yellow ring.

29-7-2019 ISABEL CATOLICA PARQUE GIJON, ASTURIAS - LITTLE EGRET (Egretta garzetta)


The Little Egret, Egretta garzetta, is a dainty heron adorned in pure white plumage. It is characterized by a slender black beak, long black legs, and, notably in the western race, yellow feet. This elegant bird is a sight to behold with its graceful neck and poised stance.

Adult Little Egrets measure between 55–65 cm in length with a wingspan of 88–106 cm, and weigh 350–550 g. Their plumage is predominantly white, though some may exhibit bluish-grey coloration. Breeding adults boast ornate nape plumes reaching about 150 mm, along with distinctive feathers on the breast and elongated scapulars. The bill and lores are black, with greenish-grey skin at the base of the lower mandible and around the eye, which houses a yellow iris. Legs are black with contrasting yellow feet, though juveniles may have greenish-black legs and duller feet. The subspecies E. g. nigripes is distinguished by yellow skin between the bill and eye, and blackish feet.


The Little Egret frequents a variety of wetland habitats, from the shores of lakes and rivers to marshes and coastal regions. It is often found in open environments, such as mangroves, swamps, mudflats, and sandy beaches, as well as human-altered landscapes like rice fields.

The species has a broad breeding distribution across warm temperate to tropical regions of Asia, Africa, Australia, and Europe. Northern populations are migratory, wintering in Africa and southern Asia, while others remain as permanent residents in warmer areas.

Little Egrets are social yet territorial when feeding. They exhibit a range of foraging behaviors, from active chasing to patient ambush. Their movements are often in response to the presence of other animals, which may stir up prey.


The Little Egret's vocalizations include croaking and bubbling sounds at breeding colonies and a harsh alarm call when disturbed. These calls are similar to those of the Black-crowned Night Heron and the Cattle Egret.

Breeding colonies are often mixed with other water birds. Nests are platforms of sticks located in trees, shrubs, or reed beds. Clutches typically consist of three to five bluish-green eggs, incubated by both parents for about three weeks. The young fledge at approximately six weeks old.

The diet is diverse, including fish, amphibians, small reptiles, mammals, birds, crustaceans, molluscs, insects, spiders, and worms. The Little Egret employs various hunting techniques, both in water and on land, to capture its prey.

29-7-2019 GIJON, ASTURIAS - MEDITERRANEAN GULL (ichthyaetus melanocephalus)


The Mediterranean gull, Ichthyaetus melanocephalus, presents a striking figure with its distinctive white plumage, pale grey mantle, and wings adorned with white primary feathers devoid of black tips. In its breeding attire, it sports a black hood that elegantly extends down the nape, punctuated by vivid white eye crescents. The bird's bill is a robust, dark red with a black subterminal band, and its legs are longer and darker compared to its relative, the black-headed gull.

When identifying the Mediterranean gull, look for a bird slightly larger and bulkier than the black-headed gull. The adult in breeding plumage is unmistakable with its black hood and lack of black wingtip markings. In non-breeding plumage, the hood recedes, leaving a dusky mask through the eye. Juveniles can be recognized by a black terminal tail band and darker areas in the upperwings, contrasting with pale underwings.

This species favors breeding in colonies located within expansive reed beds, marshes, or on lake islands. In smaller populations, it may nest alongside black-headed gull colonies.


Originally confined to the Black Sea and eastern Mediterranean, the Mediterranean gull has expanded its range dramatically, now found across Europe to the British Isles and Ireland. It winters along the Mediterranean and Atlantic coasts.

The Mediterranean gull is a sociable bird, especially in winter, forming large flocks while feeding or roosting. It is not typically found far from coasts, as it is not a pelagic species.

At colonies, this gull is quite vocal, emitting a nasal "yeah" call that contributes to the cacophony of sounds in such bustling environments.

An opportunistic omnivore, the Mediterranean gull's diet includes fish, worms, insects, eggs, young birds, offal, and carrion.

The IUCN Red List classifies the Mediterranean gull as Least Concern. It is also protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

29-7-2019 GIJON, ASTURIAS - HOUSE SPARROW (FEMALE) (Passer domesticus)


The house sparrow (Passer domesticus) is a member of the sparrow family Passeridae. This small bird typically measures around 16 cm (6.3 in) in length and weighs between 24–39.5 g (0.85–1.39 oz). The species exhibits sexual dimorphism, with females and young birds displaying pale brown and grey plumage, while males are characterized by more vibrant black, white, and brown markings.
Males can be identified by their bright black, white, and brown markings, with a distinctive black bib, white cheeks, and a grey crown. Females lack the striking head patterns of males and are predominantly buffish with softer coloration. Juveniles resemble adult females but are generally paler with less defined markings.


The house sparrow is highly adaptable and can thrive in both urban and rural environments. It is commonly found in close association with human habitation and avoids dense forests, grasslands, polar regions, and deserts far from human development.

Native to Europe, the Mediterranean Basin, and much of Asia, the house sparrow has been introduced to various regions worldwide, including parts of Australasia, Africa, and the Americas, making it one of the most widely distributed wild birds.

29-7-2019 SAN ANDRES RESERVOIR, ASTURIAS - EUROPEAN PEACOCK BUTTERFLY (Aglais io)







29-7-2019 SAN ANDRES RESERVOIR, ASTURIAS - CLEOPATRA BUTTERFLY (Gonepteryx cleopatra)


Gonepteryx cleopatra, the Cleopatra or Cleopatra butterfly, is a medium-sized butterfly of the family Pieridae.

Gonepteryx cleopatra is a medium-sized butterfly with a wingspan of about 50–70 mm (2.0–2.8 in). It is a sexually dimorphic species; the female has pale yellow or greenish wings, whereas the male is darker yellow with an orange patch on the forewing. Both sexes have a forewing apical hook and brown dots in the center of each wing, and the underside of wings is light greenish yellow. The greenish color, the shape and the pronounced venation on the hindwings give to these butterflies a good camouflage, making them resemble just leaves.


The Cleopatra butterfly inhabits open woodland and scrub. The flight period is from May to August in most parts of its range, except Spain, where it is double brooded and may fly almost all year. The adult hibernates in evergreen trees and shrubs. The caterpillars feed on the buckthorns Rhamnus alaternus. When the green caterpillars are prepared to pass to the pupal stage, they tie themselves through a silk belt to the host plant, on the underside of a leaf. The green chrysalis became gradually yellow and red, revealing the colors on the wings of the adult close to flutter. In dry regions, the Cleopatra practices a vertical migration between the maquis and the mountain fir forests. It emerges in spring at low altitudes, then migrates to higher altitudes in the mountains and stays there in the summer months to descend in autumn at low altitudes.

This species is native to the Mediterranean region (Southern Europe, North Africa and West Asia).

29-7-2019 SAN ANDRES RESERVOIR, ASTURIAS - YELLOW BELLIED SLIDER TERRAPIN (Trachemys scripta.scripta)


The yellow-bellied slider (Trachemys scripta scripta ) is a land and water turtle belonging to the family Emydidae. This subspecies of pond slider is native to the southeastern United States, specifically from Florida to southeastern Virginia, and is the most common turtle species in its range. It is found in a wide variety of habitats, including slow-moving rivers, floodplain swamps, marshes, seasonal wetlands, and permanent ponds. Yellow-bellied sliders are popular as pets.

Adult male yellow-bellied sliders typically reach 5–9 inches (13–23 cm) in length; females range from 8–13 inches (20–33 cm). The carapace (upper shell) is typically brown and black, often with yellow stripes. The skin is olive green with prominent patches of yellow down the neck and legs. As the name implies, the plastron (bottom shell) is mostly yellow with black spots along the edges. Adults tend to grow darker as they age. Yellow-bellied sliders are often confused with eastern river cooters, who also have yellow stripes on the neck and yellow undersides, but the latter lack the green spots characteristic of this species. The yellow belly often has an "s"-shaped yellow stripe on its face. They also have markings shaped like question marks on their bellies. Females of the species reach a larger body size than the males do in the same populations.

Mating can occur in spring, summer, and autumn. They have polygynandrous mating behavior. Courtship consists of biting, foreclaw display, and chasing. Yellow-bellied sliders are capable of interbreeding with other T. scripta subspecies, such as red-eared sliders, which are commonly sold as pets. The release of non-native red-eared sliders into local environments caused the state of Florida to ban the sale of red-eared sliders in order to protect the native population of yellow-bellied sliders.

29-7-2019 SAN ANDRES RESERVOIR, ASTURIAS - BUTTERFLY BUSH (Buddleja davidii)


Buddleja davidii (spelling variant Buddleia davidii), also called summer lilac, butterfly-bush, or orange eye, is a species of flowering plant in the family Scrophulariaceae, native to Sichuan and Hubei provinces in central China, and also Japan. It is widely used as an ornamental plant, and many named varieties are in cultivation. The genus was named Buddleja after Reverend Adam Buddle, an English botanist. The species name davidii honors the French missionary and explorer in China, Father Armand David, who was the first European to report the shrub. It was found near Ichang by Dr Augustine Henry about 1887 and sent to St Petersburg. Another botanist-missionary in China, Jean-André Soulié, sent seed to the French nursery Vilmorin, and B. davidii entered commerce in the 1890s.

B. davidii was accorded the RHS Award of Merit (AM) in 1898, and the Award of Garden Merit (AGM) in 1941.

29-7-2019 ISABEL CATOLICA PARQUE GIJON, ASTURIAS - RED CRESTED POCHARD (FEMALE) (Netta rufina)


The Red-crested Pochard, Netta rufina, is a striking large diving duck. Its name is drawn from the Greek word for duck, 'Netta', and the Latin 'rufina', meaning 'golden-red', a nod to the male's vibrant plumage.
Males are resplendent with a rounded orange head, a red bill, and a contrasting black breast. Their sides are a crisp white, with a brown back and a black tail. Females, on the other hand, are clad in more subdued tones, primarily pale brown with a darker back and crown, and a whitish face. During eclipse, males resemble females but retain their red bills.

These ducks favor lowland marshes and lakes, thriving in the wetland habitats of southern Europe.

The Red-crested Pochard breeds from the steppe and semi-desert regions near the Black Sea to Central Asia and Mongolia. It is a somewhat migratory species, with northern populations wintering in the Indian Subcontinent and Africa.

Gregarious by nature, Red-crested Pochards form large flocks in the winter, often mingling with other diving ducks such as the Common Pochard. They are known to both dive and dabble for their food.

30-7-2019 BOTANICO ATLANTICO GIJON, ASTURIAS - EUROPEAN ROBIN (Erithacus rubecula)






30-7-2019 TAZONES, ASTURIAS - LESSER BLACK BACKED GULL (Larus fuscus)


The lesser black-backed gull (Larus fuscus) is a large gull, distinguishable by its size and the coloration of its plumage. It is smaller than the European herring gull and exhibits a range of mantle colors across its subspecies, from dark grey to jet black.
Adult lesser black-backed gulls have yellow legs and a yellow bill with a red spot. Their wings and back are either black or dark grey, depending on the subspecies. In winter, the head becomes greyer. Juveniles display scaly black-brown upperparts and a distinctive wing pattern. They can be differentiated from juvenile herring gulls by their darker, unbarred tertial feathers.

This species is found along coasts and lakes, where it breeds and feeds. It has adapted to urban environments in some cities, nesting alongside herring gulls.

The lesser black-backed gull breeds on the Atlantic coasts of Europe and is migratory, wintering from the British Isles to West Africa. It has expanded its range to North America, particularly along the east coast, where it is now present year-round in increasing numbers.

These gulls are social birds, breeding colonially. They exhibit a fixed action pattern during feeding, where the young peck at the red spot on the adult's bill to induce regurgitation.
