25-5-2017 ALDEA ROQUETA, VALENCIA - PAINTED LADY BUTTERFLY (Vanessa cardui)
V. cardui is one of the most widespread of all butterflies, found on every continent except Antarctica and South America. In Australia, V. cardui has a limited range around Bunbury, Fremantle, and Rottnest Island. However, its close relative, the Australian painted lady (V. kershawi, sometimes considered a subspecies) ranges over half the continent. Other closely related species are the American painted lady (V. virginiensis) and the West Coast lady (V. annabella).
Male and female. Upperside. Ground-colour reddish-ochreous, basal areas olivescent-ochreous-brown; cilia black, alternated with white, Forewing with an outwardly-oblique black irregular-shaped broken band crossing from middle of the cell to the disc above the submedian vein; the apical area from end of cell and the exterior border also black; before the apex is a short white outwardly-oblique streak and a curved row of four round spots, the second and third being small; a marginal pale lunular line with its upper portion most defined and whitish. Hind-wing with a blackish patch from the costal vein across end of cell, a partly confluent recurved discal band, a submarginal row of lunules, and then a marginal row of somewhat scutiform spots; between the discal band and submarginal lunules is a row of five round black spots, which in some examples show a pale and dark outer ring. Underside. Forewing brighter reddish-ochreous, the apical area and outer margin much paler, the apex being olivescent ochreous-brown; discal irregular band as above, subapical white streak, row of spots and marginal lunules distinct; base of wing and interspace before end of cell white. Hindwing transversely-marbled with olivescent ochreous-brown and speckled with black scales; crossed by basal and discal sinuous whitish or pale fascia and intersected by white veins; an outer-discal row of five ocelli, the upper one smallest and usually imperfect, the second and fifth the largest, the fourth with black centre speckled with blue and ringed with yellow, and the second and fifth also with an outer black ring; submarginal lunules purpurescent-grey, bordered by a whitish fascia; outer margin ochreous. Body olivescent ochreous-brown, abdomen with ochreous bands; palpi blackish above, white beneath; body beneath and legs greyish-white; antennae black above, tip and beneath reddish.
The painted lady uses over 300 recorded host plants according to the HOSTS database.
Adult butterflies feed on flower nectar and aphid honeydew.
Vanessa cardui spring migration between North Africa and Europe
V. cardui occurs in any temperate zone, including mountains in the tropics. The species is resident only in warmer areas, but migrates in spring, and sometimes again in autumn. It migrates from North Africa and the Mediterranean to Britain and Europe in May and June, occasionally reaching Iceland, and from the Red Sea basin, via Israel and Cyprus, to Turkey in March and April.] The occasional autumn migration made by V. cardui is likely for the inspection of resource changes; it consists of a round trip from Europe to Africa.
For decades, naturalists have debated whether the offspring of these immigrants ever make a southwards return migration. Research suggests that British painted ladies do undertake an autumn migration, making 14,500 km (9,000 mi) round trip from tropical Africa to the Arctic Circle in a series of steps by up to six successive generations. The Radar Entomology Unit at Rothamsted Research provided evidence that autumn migrations take place at high altitude, which explains why these migrations are seldom witnessed. In recent years, thanks to the activity of The Worldwide Painted Lady Migration citizen science project, led by the Barcelona-based Institute of Evolutionary Biology (Catalan: Institut de Biologia Evolutiva), the huge range of migration has begun to be revealed. For example, some butterflies migrated from Iceland to the Sahara desert, and even further south.
V. cardui is known for its distinct migratory behaviour. In California, they are usually seen flying from north to north-west. These migrations appear to be partially initiated by heavy winter rains in the desert where rainfall controls the growth of larval food plants.[18] In March 2019, after heavy rain produced an abundance of vegetation in the deserts, Southern California saw these butterflies migrating by the millions across the state.
Similarly, heavier than usual rain during the 2018-2019 winter seems to have been the cause of the extraordinarily large migration observed in Israel at the end of March, estimated at a billion individual butterflies. Painted lady migration patterns are highly erratic and they do not migrate every year. Some evidence suggests that global climatic events, such as el Niño, may affect the migratory behaviour of the painted lady butterflies, causing large-scale migrations. The first noticeable wave of migration in eastern Ukraine was noted in the 20s of April 2019. From May 15, numbers began to grow and it was possible to observe hundreds of this species in the Kharkiv region of Ukraine, including in the city streets of Kharkiv.
Based on experimental data, the painted lady's migration pattern in northern Europe apparently does not follow a strict north-west heading. The range of headings suggests that migrating butterflies may adjust their migration patterns in response to local topographical features and weather, such as strong wind patterns. Laboratory-raised autumn-generation painted lady butterflies were able to distinguish a southern orientation for a return migration path. According to the same laboratory-based study, when butterflies were isolated from the sun, they were unable to orient themselves in a specific direction, opposed to those that did have access to the sun. This suggests that V. cardui requires a direct view of the sky, implying the use of a solar compass to orient its migratory direction and maintain a straight flight path.
A 2024 Nature Communications article provided the first evidence that the painted lady, or any insect, had traveled across an ocean. Specimens were captured on a beach in French Guiana, outside the painted lady's natural habitat. Pollen grains from the butterflies' bodies matched species of West African shrubs that flowered at the same time of year. The researchers also analyzed the butterflies' genomes and used isotope tracing to confirm that they were born in Europe or Africa. Finally, the study found that the trade wind conditions from Africa to South America were "exceptionally favorable" at that time, which would have allowed the butterflies to be propelled over 2,600 miles (4,200 km)—one of the longest journeys of an insect ever recorded.
Groups of two to eight painted lady butterflies have been observed to fly incircles around each other for about one to five seconds before separating, symbolizing courtship. Groups of butterflies usually will not fly more than 4.5 m (15 ft) away from the starting point. To establish and defend their territories, adult males perch in the late afternoon in areas where females are most likely to appear. Once the male spots a female of the same species, he begins pursuit of her. If the foreign butterfly is a male, the original male will give chase, flying vertically for a few feet before returning to his perch.
V. cardui establishes territories within areas sheltered by hedgerows. Vanessa cardui tend to inhabit sunny, brightly lit, open environments and are often attracted to open areas of flowers and clovers. Adults spend time in small depressions in the ground on overcast days.
23-5-2017 ALDEA ROQUETA, VALENCIA - EURASIAN GOLDEN ORIOLE (Oriolus oriolus)
The Eurasian golden oriole (Oriolus oriolus) is the only member of the Old World oriole family of passerine birds breeding in Northern Hemisphere temperate regions. The name "oriole" was first used in the 18th century and is an adaptation of the scientific Latin genus name, which is derived from the Classical Latin "aureolus" meaning golden. Various forms of "oriole" have existed in Romance languages since the 12th and 13th centuries. Albertus Magnus used the Latin form oriolus in about 1250 and erroneously stated that it was onomatopoeic because of the golden oriole's song. In medieval England, its name, derived from the song, was the woodwele.
Males of this species are golden yellow in color with black wings that have yellow-tipped coverts. Females are almost greenish with a yellowish-white belly. Despite the bright colors of males it's quite difficult to spot these birds in the yellow and green leaves of the canopy due to their secretive habits.

26-5-2017 MARJAL DE MOROS, VALENCIA - KENTISH PLOVER (Charadrius alexandrinus)
The Kentish plover, Anarhynchus alexandrinus, is a diminutive wader of the family Charadriidae. It is a bird of saline lakeshores, lagoons, and coastal regions, where it frequents sand dunes, marshes, semi-arid deserts, and tundra. Exhibiting sexual dimorphism, both sexes have pale plumage with a white underside and a grey/brown back, but males are distinguished by dark incomplete breast bands and head markings.
Adult Kentish plovers possess dark legs and bills. Males, during the breeding season, are adorned with a black head bar, dark breast bands, black ear coverts, and a rufous nape and crown, though variations exist among populations. Females are paler and lack the dark markings. As the breeding season wanes, the differences between sexes diminish. Males typically have longer tarsi and flank feathers, the latter being advantageous for incubation and brood care.
Kentish plovers select breeding habitats with low elevation, sparse vegetation, and high moisture, away from human disturbance. They show a preference for open, moist nesting sites and are known to move chicks to areas with better food availability.
This species boasts a vast geographical range, from North Africa to Central Asia and Europe. It is found in countries such as Senegal, China, Spain, and Austria. Some populations are migratory, wintering in Africa, while others, including various island populations, are resident.
26-5-2017 ALDEAROQUETA, VALENCIA - GREAT TIT (Parus major)
The Great tit (Parus major) is a widespread and common songbird throughout Europe, the Middle East, Central Asia, and east across the Palearctic to the Amur River, south to parts of North Africa. It has adapted well to human changes in the environment and is a common and familiar bird in urban parks and gardens. It is also an important study species in ornithology.
The Great tit has a distinctive appearance that makes it easy to recognize. The nominate race has a bluish-black crown, black neck, throat, bib, and head, and white cheeks and ear coverts. The breast is bright lemon-yellow and there is a broad black mid-line stripe running from the bib to the vent. There is a dull white spot on the neck turning to greenish yellow on the upper nape. The rest of the nape and back are green-tinged with olive. The wing-coverts are green, and the rest of the wing is bluish-grey with a white wing bar. The tail is bluish-grey with white outer tips. The plumage of the female is similar to that of the male except that the colors are overall duller.

25-5-2017 USERES, VALENCIA - RED RUMPED SWALLOW (Cecropis daurica)
The Red-rumped Swallow (Cecropis daurica) is a small, graceful passerine bird, a member of the swallow family. It is characterized by its blue upperparts and dusky underparts, with a distinctive pale or reddish rump, face, and neck collar. Unlike the Barn Swallow, it lacks a breast band but features black undertails. Its wings are broad yet pointed, allowing for swift and agile flight.
To identify the Red-rumped Swallow, look for its darker underparts compared to the Barn Swallow, and the absence of a breast band. The rump is pale or reddish, providing a stark contrast to the blue upperparts. The bird's flight is fast, with frequent swoops as it pursues airborne insects.
This species is often found in open hilly country, where it can be seen gracefully hawking for insects over grasslands. It is also known to adapt to human structures, nesting under cliff overhangs, on buildings, and bridges.
The Red-rumped Swallow has a wide distribution, breeding in temperate southern Europe and Asia, from Portugal and Spain to Japan, India, Sri Lanka, and tropical Africa. While the Indian and African populations are resident, European and other Asian birds are migratory, wintering in Africa or India.
These swallows are gregarious outside the breeding season, often seen in large numbers on the plains of India. They do not typically form large breeding colonies but are known to be social. Their flight is characterized by swift, agile movements as they feed on insects in the air.
The Red-rumped Swallow communicates with a series of chirps and trills, a delightful symphony that fills the air especially during the breeding season.
The Red-rumped Swallow constructs quarter-sphere nests with a tunnel entrance, using mud collected in their beaks. They lay 3 to 6 eggs and prefer to nest under cliff overhangs or on human-made structures.
The Red-rumped Swallow may be confused with the Barn Swallow but can be distinguished by its darker underparts, lack of a breast band, and the pale or reddish rump.
This species is an aerial insectivore, feeding on insects caught in flight. They are adept at catching their prey mid-air, often following cattle or taking advantage of grass fires to find insects.
The Red-rumped Swallow is classified as Least Concern by the IUCN. It has a vast range and a population in the millions, with no significant declining trends observed. In Europe, the species is expanding its range northward.
23-3-2017 TROGON LODGE COSTA RICA - ONE SPOTTED PREPONA BUTTERFLY (Archaeoprepona demophon)
Archaeoprepona demophon, the one-spotted prepona, banded king shoemaker, or demophon shoemaker is a butterfly belonging to the family Nymphalidae.
The wingspan reaches about 54–58 millimetres (2.1–2.3 in). The uppersides of the wings are black, with bright pale blue transverse bands. The undersides are pale brown with a clearer band in the middle of the hindwings and several dark small dots on the margins.
The butterfly larva generally feed on plants of the genus Annona (Annonaceae) and on Malpighia glabra (Malpighiaceae). Adults visit rotten fruit or dung.
This species can be found in Mexico, Central America, the West Indies, and northern portions of South America.
Archaeoprepona demophon prefers the edges of forest canopy and subcanopy.

24-5-2017 ALDEA ROQUETA, VALENCIA - SARDINIAN WARBLER (MALE) (Sylvia melanocephala)
The Sardinian warbler (Curruca melanocephala ) is a common and widespread typical warbler from the Mediterranean region. Like most Curruca species, it has distinct male and female plumages. The adult male has a grey back, whitish underparts, black head, white throat and red eyes. Plumages are somewhat variable even in the same locality, with the intensity of a reddish hue on upper- and/or underside that varies from absent to (in some subspecies) pronounced. The female is mainly brown above and buff below, with a grey head. The Sardinian warbler's song is fast and rattling, and is very characteristic of the Mediterranean areas where this bird breeds.
It breeds in the southernmost areas of Europe and just into Asia in Turkey and the eastern end of the Mediterranean. This small passerine bird, unlike most "warblers", is not particularly migratory, but some birds winter in north Africa, and it occurs as a vagrant well away from the breeding range, as far as Great Britain.
This is a bird of open country and cultivation, with bushes for nesting. The nest is built in low shrub or brambles, and 3-6 eggs are laid. Like most "warblers", it is insectivorous, but will also take berries and other soft fruit.
23-3-2017 SAN GERARDO DE DOTA COSTA RICA - RED HEADED BARBET (FEMALE) (Eubucco bourcierii)
The red-headed barbet (Eubucco bourcierii) is a species of bird in the family Capitonidae, the New World barbets. It is found in Costa Rica, Guyana, Panama, Venezuela, Colombia, Ecuador and Peru.
The female's crown and nape vary from dull orange to shades of green among the subspecies. Several have a black forehead. Its back is green, the throat grayish yellow with a yellow to orange band below it. Its lower breast is olive-yellow and the belly white. As in the male, there is some variation among subspecies.
24-5-2017 ALDEA ROQUETA, VALENCIA - EURASIAN GOLDEN ORIOLE (Oriolus oriolus)
The Eurasian golden oriole (Oriolus oriolus) is the only member of the Old World oriole family of passerine birds breeding in Northern Hemisphere temperate regions. The name "oriole" was first used in the 18th century and is an adaptation of the scientific Latin genus name, which is derived from the Classical Latin "aureolus" meaning golden. Various forms of "oriole" have existed in Romance languages since the 12th and 13th centuries. Albertus Magnus used the Latin form oriolus in about 1250 and erroneously stated that it was onomatopoeic because of the golden oriole's song. In medieval England, its name, derived from the song, was the woodwele.
Males of this species are golden yellow in color with black wings that have yellow-tipped coverts. Females are almost greenish with a yellowish-white belly. Despite the bright colors of males it's quite difficult to spot these birds in the yellow and green leaves of the canopy due to their secretive habits.
23-3-2017 SAN GERARDO DE DOTA COSTA RICA - COMMON MORPHO (Morpho helenor)
Morpho helenor, the Helenor blue morpho or common blue morpho, is a Neotropical butterfly found throughout Central and South America from Mexico to Argentina. It is a species group that may or may not be several species. Many subspecies have been described.
The larvae of subspecies Morpho helenor achillaena have been recorded as feeding on Genipa americana, Inga, Machaerium, Platymiscium, Wisteria, Trifolium, Arachis and Robinia.

23-5-2017 ALDEAROQUETA, VALENCIA - WHITE WAGTAIL (Motacilla alba)
The White wagtail is a slender bird with the characteristic long, constantly wagging tail of its genus. There are a number of other subspecies, some of which may have arisen because of partial geographical isolation, such as the resident British and Irish form, the pied wagtail M. a. yarrellii, which now also breeds in adjacent areas of the neighbouring European mainland. The Pied wagtail exchanges the grey colour of the nominate form with black (or very dark grey in females), but is otherwise identical in its behaviour. Other subspecies, the validity of some of which is questionable, differ in the colour of the wings, back, and head, or other features. Some rraces show sexual dimorphism during the breeding season. As many as six subspecies may be present in the wintering ground in India or Southeast Asia and here they can be difficult to distinguish.
White wagtails breed throughout Eurasia, only being absent in the Arctic. They also breed in the mountains of Morocco and western Alaska. These birds are residents in the milder parts of their range such as western Europe and the Mediterranean, but migratory in much of the rest of their range. Northern European breeders winter around the Mediterranean and in tropical and subtropical Africa, and Asiatic birds move to the Middle East, India, and Southeast Asia. Birds from the North American population also winter in tropical Asia. White wagtails occupy a wide range of habitats but are absent from deserts. They inhabit grasslands, seashores, rocky shorelines, sand beaches, tidepools, rivers, lakeshores, farmland, gardens, and parks. They are also often found in towns and villages.
The White wagtail (Motacilla alba) is a small insectivorous bird of the open country, often near habitation and water. It prefers bare areas for feeding, where it can see and pursue its prey. In urban areas, it has adapted to foraging on paved areas such as car parks. It is the national bird of Latvia and has been featured on the stamps of several countries.
The call of the white wagtail is a sharp chisick, slightly softer than the version given by the pied wagtail. The song is more regular in white than pied, but with little territorial significance, since the male uses a series of contact calls to attract the female.
There are a number of other subspecies, some of which may have arisen because of partial geographical isolation, such as the resident British and Irish form, the pied wagtail M. a. yarrellii, which now also breeds in adjacent areas of the neighbouring European mainland. The pied wagtail, named for naturalist William Yarrell, exchanges the grey colour of the nominate form with black (or very dark grey in females), but is otherwise identical in its behaviour. Other subspecies, the validity of some of which is questionable, differ in the colour of the wings, back, and head, or other features. Some races show sexual dimorphism during the breeding season. As many as six subspecies may be present in the wintering ground in India or Southeast Asia and here they can be difficult to distinguish. Phylogenetic studies using mtDNA suggest that some morphological features have evolved more than once, including the back and chin colour. Breeding M. a. yarrellii look much like the nominate race except for the black back, and M. a. alboides of the Himalayas differs from the Central Asian M. a. personata only by its black back. M. a. personata has been recorded breeding in the Siddar Valley of Kashmir of the Western Himalayas. It has also been noted that both back and chin change colour during the pre-basic moult; all black-throated subspecies develop white chins and throats in winter and some black-backed birds are grey-backed in winter.
21-5-2017 PEGO MARJAL, ALICANTE - GREAT REED WARBLER (Acrocephalus arundinaceus)
The great reed warbler (Acrocephalus arundinaceus ) is a Eurasian passerine in the genus Acrocephalus.
The genus name Acrocephalus is from Ancient Greek akros, "highest", and kephale, "head". It is possible that Naumann and Naumann thought akros meant "sharp-pointed". The specific arundinaceus is from Latin and means "like a reed", from arundo, arundinis, "reed".
It used to be placed in the Old World warbler assemblage, but is now recognized as part of the marsh and tree-warbler family (Acrocephalidae). Great reed warblers are medium-sized birds and are the largest of the European warblers. They breed throughout mainland Europe and the west Palearctic and migrate to sub-Saharan Africa in the winter. Great reed warblers favour reed beds as their habitat during breeding months, while living in reed beds, bush thickets, rice fields, and forest clearings during the winter. Great reed warblers exhibit relatively low sexual dimorphism, and both genders of the species are similar in appearance. This species mates both polygynously and monogamously.
The thrush-sized warbler is one of the largest species of the former family, the Old World warblers and it stands as one of the largest species in the family Acrocephalidae. It measures 16–21 cm (6.3–8.3 in) in length, 25 to 30 cm (9.8 to 11.8 in) in wingspan and weighs 22 to 38 g (0.78 to 1.34 oz). The adult has unstreaked brown upperparts and dull buffish-white chin and underparts. The forehead is flattened, and the bill is strong and pointed. It looks very much like a giant Eurasian reed warbler (A. scirpaceus ), but with a stronger supercilium.
The sexes are identical, as with most old world warblers, but young birds are richer buff below.
The warbler's song is very loud and far-carrying. The song's main phrase is a chattering and creaking carr-carr-cree-cree-cree-jet-jet, to which the whistles and vocal mimicry typical of marsh warblers are added.

22-3-2017 TROGON LODGE, COSTA RICA - RUFOUS COLLARED SPARROW (Zonotrichia capensis)
The Rufous-collared Sparrow, also known as the Andean Sparrow, is a small, charming bird measuring 13.5–15 cm in length and weighing between 20–25 grams. Adults are recognized by their stubby grey bills and a distinctive grey head marked with broad black stripes on the crown sides, and thinner stripes through the eye and below the cheeks. A notable rufous nape and breast sides complement their black-streaked buff-brown upperparts, and they exhibit two white wing bars. Their throats are white, transitioning to off-white underparts that become brown on the flanks, highlighted by a black breast patch. Juveniles present a more subdued appearance with duller, indistinct head patterns and streaked underparts, lacking the adult's rufous collar.
When identifying this species, look for the rufous collar around the nape and the black stripes on the head. The two white wing bars are also key features. The largest subspecies, found on the tepuis, has grey underparts and a more extensive rufous collar that appears as a band of black freckles across the breast.
The Rufous-collared Sparrow thrives in a variety of open or semi-open habitats, including cultivated lands, gardens, parks, grasslands, and scrubby second growth or cerrado. It is well-adapted to urban and suburban environments but is notably absent from dense Amazonian forests.
This adaptable bird ranges from the extreme south-east of Mexico to Tierra del Fuego, and on the island of Hispaniola in the Caribbean. In the northern and western parts of its range, it is typically found at altitudes of 600–4,000 meters, while in the southern and eastern parts, it is commonly found down to near sea level.
The Rufous-collared Sparrow is often seen in pairs or small flocks, holding small territories. It is known for its tame and approachable nature, making it a familiar sight across its extensive range.
The male's song is a delightful mix of slurred whistles and trills, varying geographically. Calls include a sharp "tsip." Listen for songs that may include tee-teeooo, e’e’e’e’e, or teeooo, teeeee, often delivered from a low perch.
Breeding is influenced by food availability and rainfall. Nests are open cups of plant material lined with fine grasses, placed in vegetation on the ground or low in a tree or bush. Females lay two or three pale greenish-blue eggs with reddish-brown blotches, which are incubated for 12–14 days. Males assist in feeding the chicks, which fledge after about two weeks. Brood parasitism by species such as the shiny cowbird may occur.
This sparrow forages on the ground for seeds, fallen grain, insects, and spiders. It may join mixed-species feeding flocks and has been observed picking termites from spider webs.
The Rufous-collared Sparrow is classified as Least Concern by the IUCN, thanks to its widespread distribution and adaptability to human-altered environments.

23-3-2017 SAN GERARDO DE DOTA COSTA RICA - RED HEADED BARBET (MALE) (Eubucco bourcierii)
The red-headed barbet (Eubucco bourcierii) is a species of bird in the family Capitonidae, the New World barbets. It is found in Costa Rica, Guyana, Panama, Venezuela, Colombia, Ecuador and Peru.
Male red-headed barbet subspecies except E. b. occidentalis range in weight from 30 to 41 g (1.1 to 1.4 oz). Females except occidentalis weigh 31 to 38 g (1.1 to 1.3 oz). Male occidentalis weigh 37.8 to 45.1 g (1.33 to 1.59 oz) and females 37.8 to 43.7 g (1.33 to 1.54 oz). Males have a red head, an orange to yellow breast, and a white belly . A white collar separates the head from the olive green back. The amount of red on the throat and chest and the width of the orange-yellow breast band vary among the subspecies.
21-5-2017 PEGO MARJAL, ALICANTE - PURPLE HERON (Ardea purpurea)
The purple heron (Ardea purpurea ) is a wide-ranging species of wading bird in the heron family, Ardeidae. The scientific name comes from Latin ardea "heron", and purpureus, "coloured purple". It breeds in Africa, central and southern Europe, and southern and eastern Asia. The Western Palearctic populations migrate between breeding and wintering habitats whereas the African and tropical-Asian populations are primarily sedentary, except for occasional dispersive movements.
It is similar in appearance to the more common grey heron but is slightly smaller, more slender and has darker plumage. It is also a more evasive bird, favouring densely vegetated habitats near water, particularly reed beds. It hunts for a range of prey including fish, rodents, frogs and insects, either stalking them or standing waiting in ambush.
Purple herons are colonial breeders and build a bulky nest out of dead reeds or sticks close to the water' edge among reeds or in dense vegetation. About five bluish-green eggs are laid and are incubated by both birds. The young hatch about four weeks later and fledge six weeks after that. The International Union for Conservation of Nature notes that the global population trend is downwards, largely because of the drainage of wetlands, but assesses the purple heron's conservation status as being of "least concern".
