1-4-2018 BIRDS OF EDEN, SOUTH AFRICA - DOUBLE TOOTHED BARBET (Lybius bidentatus)
%2020.jpg)
The double-toothed barbet (Pogonornis bidentatus) is a species of bird in the family Lybiidae. It is found in Angola, Benin, Burundi, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Ethiopia, Gabon, Ghana, Guinea, Guinea-Bissau, Kenya, Liberia, Mali, Nigeria, Rwanda, Sierra Leone, South Sudan, Tanzania, Togo, and Uganda. Within Lybius bidentatus, there are two subspecies: Lybius bidentatus bidentatus and Lybius bidentatus aequatorialis.
.
Pogonornis bidentatus is a barbet with black and red coloring. Its bill is large and off-white, and the skin around its eyes is yellow. The double-toothed barbet is black on the top side of its body with a patch of white feathers on its back. Its breast is red, with a white patch on its side. Females and males have similar markings, except that females have lines of black feathers on the white side patch. Juveniles of the species are duller; their feathers are dark grey..
Its song is somewhat like a cat's purr. Sometimes pairs of double-toothed barbets will sing together.
Double-toothed barbets generally live in the understory of dense woodland. They occupy the edges of the woods, riparian forest, and secondary forest. Some may go into gardens and forage for fruit.
The double-toothed barbet is most likely to be confused with the black-breasted barbet or the bearded barbet. In flight, it's ungraceful.
Pogonornis bidentatus eats fruits and insects. They search in the foliage for food, usually staying below ten meters. Of insects, they eat beetles, termites, ants, and Hemiptera, which they find in the tree bark or in clusters of leaves. Often a double-toothed barbet will capture winged ants or termites while in flight. They also eat fruits: figs, papayas, avocados, and the fruits of the umbrella tree Musanga and of Solanum. Double-toothed barbets will eat the seeds of some fruits.
These barbets can be found in pairs or small family groups with helpers; lone double-toothed barbets are rare. Their territories are large.
Double-toothed barbets roost communally, as all the barbets in a group roost in the same hole. Nests are made by excavating a tree, often rotting, at above two meters. Both barbets in a pair will dig out the nesting hole, and both will defend it. The entrance to the nest is circular, five or more centimeters across. Some nests have an entrance tunnel. At maximum, a nest is 46 cm deep.

30-11-2015 SIEM REAP, CAMBODIA - COMMON EVENING BROWN BUTTERFLY (Melanitis leda)
Melanitis leda, the common evening brown, is a common species of butterfly found flying at dusk. The flight of this species is erratic. They are found in Africa, South Asia and South-east Asia extending to parts of Australia.
Wet-season form: Forewing: apex subacute; termen slightly angulated just below apex, or straight. Upperside brown. Forewing with two large subapical black spots, each with a smaller spot outwardly of pure white inwardly bordered by a ferruginous interrupted lunule; costal margin narrowly pale. Hindwing with a dark, white-centred, fulvous-ringed ocellus subterminally in interspace two, and the apical ocellus, sometimes also others of the ocelli, on the underside, showing through.
Underside paler, densely covered with transverse dark brown striae; a discal curved dark brown narrow band on forewing; a post-discal similar oblique band, followed by a series of ocelli: four on the forewing, that in interspace 8 the largest; six on the hindwing, the apical and subtornal the largest.
Dry-season form: Forewing: apex obtuse and more or less falcate; termen posterior to falcation straight or sinuous. Upperside: ground colour similar to that in the wet-season form, the markings, especially the ferruginous lunules inwardly bordering the black sub-apical spots on forewing, larger, more extended below and above the black costa. Hindwing: the ocellus in interspace 2 absent, posteriorly replaced by three or four minute white subterminal spots.
Underside varies in colour greatly. Antennae, head, thorax and abdomen in both seasonal forms brown or greyish brown: the antennae annulated with white, ochraceous at apex.

27-3-2019 MARJAL DE MOROS, VALENCIA - KNAPWEED (Genus Centaurea)
Centaurea (/ˌsɛntɔːˈriːə/)[1] is a genus of over 700 species of herbaceous thistle-like flowering plants in the family Asteraceae. Members of the genus are found only north of the equator, mostly in the Eastern Hemisphere; the Middle East and surrounding regions are particularly species-rich.
Common names for this genus are centaury, centory, starthistles, knapweeds, centaureas and the more ambiguous bluets; a vernacular name used for these plants in parts of England is loggerheads (common knapweed). The Plectocephalus group – possibly a distinct genus – is known as basketflowers. Cornflower is used for a few species, but that term more often specifically means either C. cyanus (the annual cornflower) or Centaurea montana (the perennial cornflower). The common name centaury is sometimes used, although this also refers to the unrelated plant genus Centaurium.[2]
The name is said to be in reference to Chiron, the centaur of Greek mythology who discovered medicinal uses of a plant eventually called "centaury".
27-3-2019 MARJAL DE MOROS, VALENCIA - SMALL WHITE BUTTERFLY (Pieris rapae)
Pieris rapae is a small- to medium-sized butterfly species of the whites-and-yellows family Pieridae. It is known in Europe as the small white, in North America as the cabbage white or cabbage butterfly, on several continents as the small cabbage white, and in New Zealand as the white butterfly. The butterfly is recognizable by its white color with small black dots on its wings, and it can be distinguished from P. brassicae by the latter's larger size and black band at the tip of the forewings.
The caterpillar of this species, often referred to as the "imported cabbageworm", is a pest to crucifer crops such as cabbage, kale, bok choy and broccoli. Pieris rapae is widespread in Europe and Asia; it is believed to have originated in the Eastern Mediterranean region of Europe, and to have spread across Eurasia thanks to the diversification of brassicaceous crops and the development of human trade routes. Over the past two centuries, it spread to North Africa (about 1800), North America (1860s), Hawaii (1897), New Zealand (1930), and Australia (1937), as a result of accidental introductions.
27-3-2019 MARJAL DE MOROS, VALENCIA - BLACK WINGED STILT (Himantopus himantopus)
%2020.jpg)
The Black-winged Stilt has a wide range, extending across Europe, Asia, and Africa. Some populations migrate to coastal regions in winter, while others in milder climates may remain resident or engage in short-range movements.
Black-winged Stilts are often seen foraging in shallow waters, gracefully picking insects and crustaceans from the surface. They are known to nest in small groups, sometimes alongside avocets, and exhibit a variety of courtship behaviors, including intricate displays and duets.
The flight call of the Black-winged Stilt is a sharp and clear kleek, typically heard during its aerial maneuvers.
Nests are simple bare spots on the ground near water. These birds are communal nesters and may breed in loose colonies. They have been known to breed as far north as Britain, with recent successful breeding events recorded in Southern and Northern England.
The Black-winged Stilt can be confused with other stilt species, such as the Black-necked Stilt (H. mexicanus) in the Americas, the White-backed Stilt (H. melanurus), and the Pied Stilt (H. leucocephalus) in Australasia and New Zealand.
Their diet consists mainly of insects and crustaceans, which they deftly pick from the water's surface or from wet sand.
27-3-2019 MARJAL DE MOROS, VALENCIA - RED CRESTED POCHARD (MALE AND FEMALE) (Netta rufina)
%20(Netta%20rufina)%2020.jpg)
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.
27-3-2019 MARJAL DE MOROS, VALENCIA - WOOD SANDPIPER (Tringa glareola)
%2019.jpg)
The wood sandpiper is a small wader with dark, speckled upperparts, a white underbody, and yellow legs, identified by a distinctive white stripe over its eye. It is a migratory bird that breeds in northern Europe and Asia and winters in Africa or Asia. During its spring and autumn migrations, it stops at inland freshwater wetlands to rest and refuel. Key features in flight include a square white rump and no wing bars.

26-3-2019 MONTE CORONA, VALENCIA - MONTPELIER CISTUS (Cistus monspeliensis)
Cistus monspeliensis is a species of rockrose known by the common name Montpellier cistus or narrow-leaved cistus. It is native to southern Europe and northern Africa, in the Mediterranean forests, woodlands, and scrub ecosystems of matorral—maquis shrublands.
Cistus monspeliensis is a shrub with narrow evergreen leaves and a hairy, glandular, sticky surface. The leaves are linear to lance-shaped, green, with a rugose, wrinkled upper surface, up to 5 centimeters long. In cultivation, C. monspeliensis attains a height of around one meter and a width of 1.5 metres.
The plant's inflorescence is generally a panicle of 2 to 8 flowers, each with five sepals and five white petals.
It is mainly distributed throughout the western Mediterranean Basin (Portugal, including Madeira; Spain, including the Canary Islands and Balearic Islands; Morocco; southern France, including Corsica; Italy, including Sardinia and Sicily; Malta; Algeria; Tunisia) but it is also present in Croatia; Serbia; Albania; Montenegro; Greece and Cyprus.
The plant has been reported elsewhere as an introduced species, and in California as an invasive species.
26-3-2019 MONTE CORONA, VALENCIA - EUROPEAN FIREBUG (Pyrrhocoris apterus)
The firebug, Pyrrhocoris apterus, is a common insect of the family Pyrrhocoridae. Easily recognizable due to its striking red and black coloration, it may be confused with the similarly coloured though unrelated Corizus hyoscyami (cinnamon bug or squash bug). Pyrrhocoris apterus is distributed throughout the Palaearctic from the Atlantic coast of Europe to northwest China. It has also been reported from the United States, Central America, and India, and is also found in Australia. It has been reported as recently expanding its distribution northwards into mainland United Kingdom and eastward on to the coast of the Mediterranean Sea. They are frequently observed to form aggregations, especially as immature forms, containing from tens to perhaps a hundred individuals.
Firebugs generally mate in April and May. Their diet consists primarily of seeds from lime trees and mallows. They can often be found in groups near the base of lime tree trunks, on the sunny side.
They can be seen in tandem formation when mating which can take from 12 hours up to 7 days. The long period of copulating is probably used by the males as a form of ejaculate-guarding under high competition with other males.
P. apterus was the subject of an unexpected discovery in the 1960s when researchers who had for ten years been rearing the bugs in Prague, Czech Republic, attempted to do the same at Harvard University in the United States. After the fifth nymphal instar, instead of developing into adults, the bugs either entered a sixth instar stage, or became adults with nymphal characteristics. Some of the sixth instars went on to a seventh instar, but all specimens died without reaching maturity. The source of the problem was eventually proven to be the paper towels used in the rearing process; the effect only happened if the paper towels were made in America. The researchers could replicate these results with American newspapers such as the New York Times, but not European newspapers such as The Times. The cause was found to be hormones found in the native balsam fir tree (Abies balsamea) used to manufacture paper and related products in America, and in some other North American conifers. This hormone happened to have a profound effect on P. apterus, but not on other insect species, showing the diversification of hormone receptors in the insects. The most potent chemical component was later identified as juvabione, the methyl ester of todomatuic acid, which is produced by the trees in response to wounding; it mimics juvenile hormone closely at the chemical level, defending against vulnerable pests.
25-3-2019 VAL DE ENCANTADA, ALICANTE - HOUSE SPARROW (MALE) (Passer domesticus)
%20(Passer%20domesticus)%2020.jpg)
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.

25-3-2019 VAL DE ENCANTADA, ALICANTE - COMMON POPPY (Papaver rhoeas)
Papaver rhoeas, with common names including common poppy, corn poppy, corn rose, field poppy, Flanders poppy, red poppy, and Odai, is an annual herbaceous species of flowering plant in the poppy family Papaveraceae. It is native to north Africa and temperate Eurasia and is introduced into temperate areas on all other continents except Antarctica.
It is regarded as an agricultural weed (hence the common names including "corn" and "field"). As the plant thrives in areas of disturbed soil, it was often abundant in agricultural fields before the advent of herbicides. Flushes of poppies may still appear in fields where herbicides are not used, as well as those in fallow. The corn poppy and its cultivars such as the Shirley poppy are widely grown in gardens, and are frequently found in packets of seed labelled "wildflower mixes". Since World War I, it has been used in the Commonwealth as a symbol of remembrance for fallen soldiers because it commonly grew in fields disturbed by war.
25-3-2019 VAL DE ENCANTADA, ALICANTE - SWEET ALYSSUM (Lobularia maritima)
Lobularia maritima (syn. Alyssum maritimum) is a species of low-growing flowering plant in the family Brassicaceae. Its common name is sweet alyssum or sweet Alison, also commonly referred to as just alyssum (from the genus Alyssum in which it was formerly classified).
Lobularia maritima is an annual plant (rarely a short-lived perennial plant) growing to 5–30 cm (2–12 in) tall by 20–30 cm (8–12 in) broad. The stem is very branched, with dense clusters of small flowers. The leaves are 1–4 cm long and 3–5 mm, broad, alternate, sessile, quite hairy, oval to lanceolate, with an entire margin.
The flowers are about 5 millimetres (0.20 in) in diameter, sweet-smelling, with an aroma similar to that of honey, with four white rounded petals (or pink, rose-red, violet. yellow and lilac) and four sepals. The six stamens have yellow anthers. The flowers are produced throughout the growing season, or year-round in areas free of frost. They are pollinated by insects (entomophily) as its sweet honey-like fragrance is attractive to bees, flower flies, stingless wasps and butterflies. The fruits are numerous elongated seedpods rather hairy, oval to rounded, each containing two seeds. The dispersal of seed is affected by the wind (anemochory).
25-3-2019 VAL DE ENCANTADA, ALICANTE - PALMATE ANEMONE (Anemone palmata)
%2020.jpg)
Anemone palmata is a species of bright yellow, daisy-like flower native to the Iberian Peninsula, Southern France, Sardinia, and Sicily. It belongs to the buttercup family and can be found in damp, rocky, or open woodland habitats, blooming from March to May. It is sometimes called the palmate anemone, yellow anemone, or cyclamen-leaved windflower.
Botanical characteristics
Height: Grows to between 15 and 45 cm tall.
Leaves: Has succulent, rounded basal leaves with 3 to 5 shallow lobes.
Flowers: Produces solitary or paired, bright yellow, saucer-shaped flowers 2.5–3.5 cm across with 10–15 oblong petals. The outer surface is often tinged red.
Other: A white form of this flower also exists.

17-4-2018 CHOBE RIVER, BOTSWANA - AFRICAN FISH EAGLE (Haliaeetus vocifer)
The African fish eagle, or African sea eagle, is a majestic bird of prey that graces the skies of sub-Saharan Africa. It is a symbol of national pride, being the national bird of Malawi, Namibia, Zambia, and Zimbabwe. This raptor is known for its striking appearance, with a mostly brown body contrasted by a snow-white head, breast, and tail. The face is featherless and a vivid yellow, matching the color of its formidable, hooked beak, tipped in black. The African fish eagle's eyes are a deep, dark brown, and its powerful black wings carry it effortlessly over open waters.
Adult African fish eagles are unmistakable with their white heads and chests, brown bodies, and large black wings. Females are larger than males, with wingspans reaching up to 2.4 meters, compared to the 2-meter span of males. Juveniles can be identified by their overall brown plumage and paler eyes. The species exhibits sexual dimorphism, with females being heavier, weighing between 3.2 to 3.6 kilograms, while males weigh between 2.0 to 2.5 kilograms.
17-4-2018 CHOBE RIVER, BOTSWANA - GREATER KUDU (Tragelaphus Strepsiceros)
The Greater kudu (Tragelaphus strepsiceros) is a woodland antelope found in Africa. Despite occupying such widespread territory, Greater kudus are sparsely populated in most areas due to declining habitat, deforestation, and poaching.
Greater kudus have a narrow body with long legs, and their coats can range from brown/bluish-grey to reddish-brown. They possess between 4 and 12 vertical white stripes along their torso. The head is usually darker in color than the rest of the body and exhibits a small white v-shaped mark that runs between the eyes. Bulls tend to be much larger than cows, and vocalize much more; they also have beards running along their throats and large horns with two and a half twists.
24-3-2019 MONTE CORONA, VALENCIA - WESTERN HONEY BEE ( Apis mellifera)
The western honey bee or European honey bee (Apis mellifera) is the most common of the 7–12 species of honey bees worldwide. The genus name Apis is Latin for 'bee', and mellifera is the Latin for 'honey-bearing' or 'honey-carrying', referring to the species' production of honey.
Like all honey bee species, the western honey bee is eusocial, creating colonies with a single fertile female (or "queen"), many normally non-reproductive females or "workers", and a small proportion of fertile males or "drones". Individual colonies can house tens of thousands of bees. Colony activities are organized by complex communication between individuals, through both pheromones and the dance language.
The western honey bee was one of the first domesticated insects, and it is the primary species maintained by beekeepers to this day for both its honey production and pollination activities. With human assistance, the western honey bee now occupies every continent except Antarctica. Western honey bees are threatened by pests and diseases, especially the Varroa mite and colony collapse disorder. There are indications that the species is rare, if not extinct in the wild in Europe and as of 2014, the western honey bee was assessed as "Data Deficient" on the IUCN Red List. Numerous studies indicate that the species has undergone significant declines in Europe; however, it is not clear if they refer to population reduction of wild or managed colonies. Further research is required to enable differentiation between wild and non-wild colonies in order to determine the conservation status of the species in the wild, meaning self sustaining, without treatments or management.
