14-8-2021 ALDEA DEL OBISPO, SALAMANCA - MIGRANT SPREADWING DAMSELFLY (Lestes barbarus)
Lestes barbarus is a species of damselfly of the family Lestidae, the spreadwings. Its common names in English include southern emerald damselfly, shy emerald damselfly, and migrant spreadwing.
Lestes barbarus is a European–central Asian species with isolated populations in North Africa and a range expanding northward. It is found across southern Europe in a band across Spain, France, Italy and Greece to India and Mongolia. It is less common in northern Europe, although some are found as far north as Sweden. It breeds in the Netherlands in coastal dunes and is increasing in number. It is at the edge of its range in the Channel Islands, where it has been breeding since 1995. It is also found in North Africa; it gets its Latin name as the first specimen was found in Barbary, North Africa. It is a damselfly of still water and can be found in stagnant and slightly brackish water.
This species was first recorded in Britain at Winterton Dunes, Norfolk, on 30 July 2002. In 2003 and 2004 it was noted at Sandwich Bay, Kent. In 2018 it was proven to have bred in Britain for the first time.
This species has the typical appearance of a Lestes damselfly with a metallic green body and wings held away from the body at rest. It differs from the other European Lestes in having bicoloured pterostigmata, which is diagnostic. The male abdominal appendage and female ovipositor are also characteristic and unlike those of L. sponsa or L. dryas.
Immatures have pale pterostigmata and only develop the characteristic two-coloured pterostigmata when mature.
The flight period is from March to October in the south of its range but in north it flies mainly from June to August. Its behaviour is similar to that of L. sponsa, but it is more likely to be found away from water. After mating the pair usually remain in tandem while the female lays eggs on waterside plants. The eggs overwinter in diapause and the larvae hatch in spring. The larvae develop within two months, the adults emerging in late spring.

13-8-2021 PARQUE DE JESUITAS, SALAMANCA - WESTERN BONELLI'S WARBLER (Phylloscopus bonelli)
%2020.jpg)
The western Bonelli's warbler (Phylloscopus bonelli) is a warbler in the leaf warbler genus Phylloscopus. It was formerly regarded as the western subspecies of a wider "Bonelli's warbler" species, but as a result of modern taxonomic developments, they are now usually considered to be two species:
Western Bonelli's warbler, Phylloscopus bonelli, which breeds in southwest Europe and north Africa
Eastern Bonelli's warbler, Phylloscopus orientalis, which breeds in southeast Europe and Asia Minor
The breeding ranges of the two species do not overlap; while their appearance and songs are very similar, the calls are completely different (see below). They also show marked difference in mtDNA sequence.
%2021.jpg)
The species is migratory, wintering in sub-Saharan Africa. It is a rare vagrant in Northern Europe.
The genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The English name and the specific bonelli are for the Italian ornithologist Franco Andrea Bonelli.
Western Bonelli's warbler is a small passerine bird, found in forest and woodland. Four to six eggs are laid in a nest on the ground. The eggs are white with reddish-brown markings and are laid in clutches of 3-5 eggs. The incubation period is around 14 days long, and the chicks fledge after 10-14 days. Cuckoo nest predation and brood parasitism are major hazards to the breeding success of western Bonelli's warblers. Like most warblers, western Bonelli's warbler is insectivorous.
%2022.jpg)
The adult has a plain grey-green back, green-toned rump and wings and whitish underparts. The bill is small and pointed and the legs brown. The sexes are identical, as with most warblers.
The western Bonelli's warbler has a browner tinge to the upperparts than the eastern Bonelli's warbler; the latter sometimes has a greenish tinge instead. The song is a fast monotone trill, only slightly different from eastern Bonelli's, and also with some similarity to the wood warbler. The call of the western Bonelli's warbler is a disyllabic hu-it, differing from that of the eastern Bonelli's warbler which is a hard chup, reminiscent of a crossbill or a house sparrow.

12-8-2021 , PLAZA DE LIBERTAD, SALAMANCA - HOUSE SPARROW (MALE) (Passer domesticus)
Male House Sparrows (Passer domesticus) are highly social, adaptable urban birds distinguished from females by their striking black throat bibs, bright chestnut napes, and gray crowns. Weighing 25–30 grams and measuring 14–15 cm, they thrive alongside human settlements, relying on opportunistic diets of seeds, grains, and urban scraps.
Distinctive Plumage & StatusThe Bib: A male’s black bib (or throat patch) is a direct indicator of his status within the flock. Studies show males with larger, darker bibs rank higher, hold the safest feeding spots, and secure the best breeding territories.
Colors: They have a steel-gray crown, white cheeks, and a rich rufous-brown back heavily streaked with black.
Sexual Dimorphism: Females are much more drab, featuring plain brown and buff plumage for camouflage while nesting, lacking both the bib and bright markings.
Vocalizations: Males are highly vocal, using their loud, repetitive chirps and cheeps to declare territory and attract mates during the breeding season.

10-8-2021 ARANJEUZ, MADRID - COMMON WOOD PIGEON (Columba palumbus)
%2020.jpg)
The Common wood pigeon (Columba palumbus) is a member of the dove and pigeon family (Columbidae), native to the western Palearctic. It has historically been known as the Ring dove, and is locally known in southeast England as the "culver"; the latter name has given rise to several areas known for keeping pigeons to be named after it, such as Culver Down.
The Common wood pigeon is a large member of the dove and pigeon family. Adult birds bear a series of green and white patches on their necks and a pink patch on their chest. Juvenile birds do not have white patches on either side of the neck. When they are about six months old they gain small white patches on both sides of the neck; these patches gradually enlarge until they are fully formed when the bird is about 6-8 months old. Juvenile birds also have a greyer beak and an overall lighter grey appearance than adults.

4-8-2021 ALDAIA, VALENCIA - COMMON WOOD PIGEON (Columba palumbus)
The common wood pigeon (Columba palumbus), also known simply as the wood pigeon, is a large pigeon native to the western Palearctic. It belongs to the genus Columba, which includes closely related species such as the rock dove (Columba livia). It has a flexible diet, feeding mainly on plant material, including cereals, and is therefore considered an agricultural pest. Wood pigeons are extensively hunted over much of their range, but this does not appear to have a major impact on their population numbers.
The three Western European Columba pigeons, common wood pigeon, stock dove and rock dove, though superficially alike, have very distinctive characteristics; the common wood pigeon may be identified at once by its larger size at 38–44.5 cm (15–17+1⁄2 in) and weight 300–615 g (10+5⁄8–21+3⁄4 oz), and the white on its neck and wing. It is otherwise a basically grey bird, with a pinkish breast. The wingspan can range from 68 to 80 cm (27 to 31 in) and the wing chord measures 24 to 25.4 cm (9+1⁄2 to 10 in). The tail measures 13.8 to 15 cm (5+1⁄2 to 6 in), the bill is 1.9 to 2.2 cm (3⁄4 to 7⁄8 in) and the tarsus is 2.5 to 2.8 cm (1 to 1+1⁄8 in). Adult birds bear a series of green and white patches on their necks, and a pink patch on their chest. The eye colour is a pale yellow, in contrast to that of rock doves, which is orange-red, and the stock dove, which is dark grey-brown to black.

2-8-2021 SPACE MUSEUM, CUENCA - WHITE ANGLED SULPHUR BUTTERFLY (Anteos clorinde)
%2020.jpg)
Anteos clorinde, the white angled-sulphur, is a butterfly of the family Pieridae. The species was originally described by Jean-Baptiste Godart in 1824.
It is found in South America, Central America, and southern North America.
The wingspan is 70–90 mm. The butterfly flies year round in the tropical parts of its range and from August to December in the north.
The larvae feed on Senna spectabilis.
2-8-2021 SPACE MUSEUM, CUENCA - AMANDA'S BLUE BUTTERFLY (Polyommatus amandus)
Polyommatus amandus, the Amanda's blue, is a butterfly of the family Lycaenidae. It is found in the Palearctic realm.
With a wingspan of 29 to 35 mm (1.1 to 1.4 in), Amanda's blue is noticeably larger than most of the "blue" butterflies, which is particularly apparent when they are flying. The upperside of the male's wings is a silvery blue or sky blue, often, but not always, with a broad dark border and a narrow black marginal line with an outermost white line. The upperside of the female's wings is in some populations dark blue edged with brown but in other populations is medium brown with a row of orange half-moon shaped lunules near the edges. The hind margin has red blotches. The underside of the male's wings are light grey with white-edged black blotches. The underside of the female's wings is similar but they are a rich creamy-brown colour with red blotches, especially on the margins of the hindwings and a series of black spots with white rims, often touching, forming a row parallel to the margin of the wings. The basal areas of the underwings are turquoise. The wingspan is 28 to 36 mm (1.1 to 1.4 in).
22-8-2021 SPACE MUSEUM, CUENCA - POSTMAN BUTTERFLY (Heliconius melpomene)
%2020.jpg)
Heliconius melpomene, the postman butterfly, common postman or simply postman, is a brightly colored, geographically variable butterfly species found throughout Central and South America. It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. Its coloration coevolved with another member of the genus, H. erato, as a warning to predators of its inedibility; this is an example of Müllerian mimicry. H. melpomene was one of the first butterfly species observed to forage for pollen, a behavior that is common in other insect groups but rare in butterflies. Because of the recent rapid evolutionary radiation of the genus Heliconius and overlapping of its habitat with other related species, H. melpomene has been the subject of extensive study on speciation and hybridization. These hybrids tend to have low fitness as they look different from the original species and no longer exhibit Müllerian mimicry.
Heliconius melpomene possesses ultraviolet vision which enhances its ability to distinguish subtle differences between markings on the wings of other butterflies. This allows the butterfly to avoid mating with other species that share the same geographic range.
2-8-2021 SPACE MUSEUM, CUENCA - BLACK VEINED WHITE BUTTERFLY (Aporia crataegi)
%2020.jpg)
Aporia crataegi, the black-veined white, is a large butterfly of the family Pieridae. A. crataegi is widespread and common. Its range extends from northwest Africa in the west to Transcaucasia and across the Palearctic to Siberia and Japan in the east. In the south, it is found in Turkey, Cyprus, Israel, Lebanon and Syria. It is not usually present in the British Isles or northern Scandinavia.
It occurs in open forest, grazing land, orchards. lanes, gardens, meadows and thickets throughout most of Europe, temperate Asia, Korea, and Japan. This species has been extirpated from the British Isles, but unofficial attempts have been made to reintroduce this species in southern England.
