6-8-2017 RIVER DANUBE, PASSAU - COMMON RAVEN (Corvus corax)
%2020.jpg)
The common raven (Corvus corax) is a large all-black passerine bird. It is the most widely distributed of all corvids, found across the Northern Hemisphere. It is a raven known by many names at the subspecies level; there are at least eight subspecies with little variation in appearance, although recent research has demonstrated significant genetic differences among populations from various regions. It is one of the two largest corvids, alongside the thick-billed raven, and is possibly the heaviest passerine bird; at maturity, the common raven averages 63 centimetres (25 inches) in length and 1.47 kilograms (3.2 pounds) in mass. Although their typical lifespan is considerably shorter, common ravens can live more than 23 years in the wild. Young birds may travel in flocks but later mate for life, with each mated pair defending a territory.
Common ravens have coexisted with humans for thousands of years and in some areas have been so numerous that people have regarded them as pests. Part of their success as a species is due to their omnivorous diet; they are extremely versatile and opportunistic in finding sources of nutrition, feeding on carrion, insects, cereal grains, berries, fruit, small animals, nesting birds, and food waste. Some notable feats of problem-solving provide evidence that the common raven is unusually intelligent.
Over the centuries, the raven has been the subject of mythology, folklore, art, and literature. In many cultures, including the indigenous cultures of Scandinavia, ancient Ireland and Wales, Bhutan, the northwest coast of North America, and Siberia and northeast Asia, the common raven has been revered as a spiritual figure or godlike creature.
22-4-2016 MONTE CORONA, VALENCIA - COAL TIT (Periparus ater)
The Coal tit (Periparus ater) is a small passerine bird widespread and common resident breeder throughout the temperate to subtropical Palearctic, including North Africa.
The Coal tit has a distinctive large white nape spot on its black head. The head, throat, and neck of the adult are glossy blue-black, setting off the off-white sides of the face (tinged grey to yellow depending on subspecies) and the brilliant white nape; the white tips of the wing coverts appear as two wingbars. The underparts are whitish shading through buff to rufous on the flanks. The bill is black, the legs lead-colored, and the irides dark brown. The young birds are duller than the adults, lacking gloss on the black head, and with the white of nape and cheeks tinged with yellow.
Coal tits are found throughout Europe, Asia, and North Africa. They are all-year residents throughout almost all range, making only local movements in response to particularly severe weather; only the Siberian birds have a more regular migration. Coal tits prefer humid conifer forests but also frequent shrubland, conifer plantations, gardens, and urban areas.
Coal tits are social birds and often form small flocks in winter with other tits. They resemble other tits in acrobatic skill and restless activity, though they more frequently pitch on a trunk, and in little hops resemble a treecreeper. Coal tits are active during the day spending most of their time searching for food trees. They also visit gardens to feed on a variety of foods put out, particularly sunflower seeds. While searching for food, Coal tit flocks keep contact with incessant short 'dee' or 'see-see' calls. Their song is a strident 'if-he, if-he, if-he', heard most frequently from January to June, but also in autumn. The song resembles that of the Great tit, but much faster and higher in pitch. North African birds also have a 'currr' call similar to that of the European crested tit which is not found in Africa.
20-12-2015 JURONG, SINGAPORE - RED AND GREEN MACAW (Ara chloropterus)
%2010-gigapixel-scale-1_4x.jpg){kind=tracking}
The red-and-green macaw (Ara chloropterus), also known as the green-winged macaw, is a large, mostly-red macaw of the genus Ara.
This is the largest of the genus Ara, widespread in the forests and woodlands of northern and central South America. However, in common with other macaws, in recent years there has been a marked decline in its numbers due to habitat loss and illegal capture for the parrot trade.
%2011-gigapixel-scale-1_4x.jpg){kind=tracking}
This magnificent and easily distinguished parrot is one of the largest species of Macaw. The Green-winged macaw has yellow eyes, surrounded by bright red bars, made up of rows of small feathers, covering the white patch on the bare skin. The bird's chest, upper wings, upper back, and head are red. The legs of the bird are colored grey. The feathers of the middle wing are green with blue tips. The tail consists of motley plumage, surrounded by red feathers. The horn-colored upper beak is black on the sides while the lower beak is colored in black or dark grey.
The area of the Green-winged macaw distribution is partly Central and South America, stretching from eastern Panama to Colombia, Venezuela, and the Guianas, across the western part of South America from eastern Ecuador and eastern Peru to northern and eastern Bolivia. Throughout eastern South America, including Parana and Mato Grosso in Brazil, reaching Paraguay and Formosa in northern Argentina. The natural habitat of these birds is tropical rainforest, lowlands, and foothills. They are mainly found in interior regions, rarely occurring in coastal areas.
%2012-gigapixel-scale-1_4x.jpg){kind=tracking}
Green-winged macaws are social birds, living in pairs as well as gathering into family groups or small flocks, consisting of 6-12 individuals. In feeding trees and at clay licks, however, these birds can occasionally be seen in even larger flocks, mixing with other macaws and making a lot of noise, each bird demonstrating its full vocal range. Green-winged macaws are diurnal, spending most of the time under the dense cover of rainforest, where they find shelter as well as socialize and feed. They also spend a lot of time, playing and cleaning each other's plumage, removing lice and ticks from the feathers. If you see 3 or 4 macaws together, it will probably be a pair, and their young. These birds are extremely shy, and rarely seen in the foliage. Feeling danger, the bird immediately flies off, emitting loud screeches.
28-11-2016 JURONG, SINGAPORE - LACED WOODPECKER (MALE) (Picus vittatus)
%20(Picus%20vittatus)%2030.jpg)
The laced woodpecker (Picus vittatus) is a species of bird in the family Picidae.
It is found throughout Southeast Asia in the countries of Cambodia, China, Indonesia, Laos, Malaysia, Myanmar, Singapore, Thailand and Vietnam. A sole specimen recorded for Bangladesh has since been reidentified as a streak-breasted woodpecker.
%20Dinopium%20rafflesii)%2040.jpg)
Typical green woodpecker, with a tea-green back, gray face, and solid black moustache stripe. Male has a bright red crown while female has a dull black one. Strikingly striped wings most readily seen in flight. Gives sharp, loud “kip” calls and more strident two-note calls during confrontations. In southwestern Thailand and southern Myanmar, look out for the similar Streak-breasted Woodpecker, which has a faded, indistinct moustache stripe in both sexes. Also compare with Streak-throated Woodpecker, which, as the name suggests, has noticeable streaking on the throat, as well as a more indistinct moustache stripe.
28-11-2016 JURONG, SINGAPORE - CHESTNUT MUNIA (Lonchura atricapilla)
%2020.jpg)
The chestnut munia or black-headed munia (Lonchura atricapilla ) is a small passerine. It was formerly considered conspecific with the closely related tricoloured munia, but is now widely recognized as a separate species. This estrildid finch is a resident breeding bird in Bangladesh, Brunei, Cambodia, China, India, Indonesia, Laos, Malaysia, Burma, Nepal, the Philippines, Singapore, Taiwan, Thailand, Vietnam and Hawaii. It also has been introduced to all the Greater Antilles and Martinique in the Caribbean.
Before 1995, it was the national bird of the Philippines, where it is known as mayang pula ("red maya") because of its brick red patch on the lower back which is visible only when it flies. (This distinguishes it from other birds locally called maya, notably the predominantly brownish "mayang simbahan" (tree sparrow) which is more common in urban areas.)
14-5-2016 VILLALONGA RESERVOIR - GREY WAGTAIL (Motacilla cinerea)
This slim wagtail has a narrow white supercilium and a broken eye ring. The upperparts are grey and the yellow vent contrasting with whitish underparts makes it distinctive. The breeding male has a black throat that is edged by whitish moustachial stripes. They forage singly or in pairs on meadows or on shallow water marshes. They also use rocks in water and will often perch on trees. They have a clear sharp call note and the song consists of trills.
The breeding season is April to July and the nest is placed near fast running streams or rivers on an embankment between stones and roots. The male in display, makes short flights up into the air and descends slowly with fluttering flight accompanied by a rapid series of chipping high notes. In Europe the nests are often made in holes in manmade structures. The clutch consists of 3–6 speckled eggs and multiple broods may be raised with declining numbers in the clutch in subsequent broods. The usual clutch size is five in Ireland and the breeding success is about 80% with predation of eggs or chicks being the main cause of breeding failure. The Canary Islands population typically have smaller clutches and the breeding season is not as short and well marked as in populations at higher latitudes. The incubation period is about two weeks with chicks fledging within a fortnight. They live for a maximum of 8 years in the wild.
The grey wagtail (Motacilla cinerea) is a member of the wagtail family, Motacillidae, measuring around 18–19 cm overall length. The species looks somewhat similar to the yellow wagtail but has the yellow on its underside restricted to the throat and vent. Breeding males have a black throat. The species is widely distributed, with several populations breeding in Eurosiberia and migrating to tropical regions in Asia and Africa. The species is always associated with running water when breeding, although they may use man-made structures near streams for the nest. Outside the breeding season, they may also be seen around lakes, coasts and other watery habitats. Like other wagtails, they frequently wag their tail and fly low with undulations and they have a sharp call that is often given in flight.

The flower heads are yellow sulfur, about five centimeter wide. Involucral bracts vary from seven to eight. Blooms are abundant throughout the Spring. The flowering period extends from March through August. The long, beaked fruit is an achene, and has a feathery, slightly reddish pappus.
This plant occurs in Western and Central Mediterranean from Spain to Dalmatia and North Africa.
These plants can be found on roadsides, dry grasslands or wastelands at 0–1,200 metres (0–3,937 ft) above sea level. They are commonly grown in drained soil and sunny places throughout the year.
11-5-2016 ALCOY, ALICANTE - MALLOW BINDWEED (Convolvulus althaeoides)
Convolvulus althaeoides is a species of morning glory known by the common names mallow bindweed and mallow-leaved bindweed. This flowering plant is native to the Mediterranea Basin, but it is occasionally seen in other areas of similar climate, such as California in the United States, where it has been introduced. This is a climbing perennial plant with solitary flowers on long peduncles. The flower is a funnel-shaped pink bloom three or four centimeters wide. The leaves are deeply divided into narrow, fingerlike lobes.
11-5-2016 ALCOY, ALICANTE - BROWN GARDEN SNAIL (Cornu aspersum)
Cornu aspersum (syn. Helix aspersa, Cryptomphalus aspersus), known by the common name garden snail, is a species of land snail in the family Helicidae, which includes some of the most familiar land snails. Of all terrestrial molluscs, this species may well be the most widely known. It was classified under the name Helix aspersa for over two centuries, but the prevailing classification now places it in the genus Cornu.
The snail is relished as a food item in some areas, but it is also widely regarded as a pest in gardens and in agriculture, especially in regions where it has been introduced accidentally, and where snails are not usually considered to be a menu item.
