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.

24-3-2019 MONTE CORONA, VALENCIA - 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.

24-3-2019 PLAYA DE CULLERA, VALENCIA - SEA FIG (Carpobrotus edulis)


Carpobrotus edulis is a creeping plant with succulent leaves in the genus Carpobrotus, native to South Africa. Its common names include hottentot-fig, sour fig, ice plant, highway ice plant, or vygie.

Carpobrotus edulis is a creeping, mat-forming succulent species. It grows year round, with individual shoot segments growing more than 1 m (3 ft) per year.[citation needed] It can grow to at least 50 m (165 ft) in diameter. The leaves are a dull-green or yellow-green colour that may fade to pink with age. They are very slightly curved and have serrated sides near the tips.

The yellow flowers are produced from April to October, and range from 6.4 to 15.2 centimetres (2+1⁄2 to 6 inches) in diameter. Two of the calyx lobes are longer, extending further than the petals. The flowers open in the morning in bright sunlight and close at night. The receptacle is somewhat wedge-shaped, tapering down to the pedicel. The fruit is multi-chambered, ripening from green to yellow.


The sour fig grows on coastal and inland slopes in South Africa from Namaqualand in the Northern Cape through the Western Cape to the Eastern Cape. It is often seen as a pioneer on disturbed sites.

Carpobrotus edulis has naturalised in many other regions throughout the world, and is an invasive species in several parts, notably Australia, California and the Mediterranean, all of which have similar climates. The species has escaped from cultivation and has become invasive, posing a serious ecological problem by forming vast monospecific zones, lowering biodiversity, and competing directly with several threatened or endangered plant species for nutrients, water, light, and space.


The success of C. edulis as an invader is linked to its stoloniferous growth habit and clonal integration, traits commonly associated with invasive species. Physiological integration between ramets increases survival, biomass accumulation and clonal spread especially where competing with native species. The species often exhibits greater phenotypic plasticity than many native species, enabling it to establish and expand into under contrasting conditions including shaded coastal cliffs and nutrient-enriched sites. Such plasticity has raised concerns about its continual spread, especially in the face of changing climatic conditions.

Through hybridization, invasive C. edulis can gain genetic diversity and novel traits that further enhance its adaptability. The species readily engages in genetic exchanges with other Carpobrotus, such as C. chilensis, leading to hybrid variants with unique genetic combinations that allow them to thrive and outcompete native flora. Analysis of chloroplast DNA has revealed a large amount of genetic similarities between C. edulis and C. chilensis, indicating that the two may share a common ancestor.

24-3-2019 PLAYA DE CULLERA, VALENCIA - COMMON MALLOW (Malva sylvestris)


Malva sylvestris is a species of the mallow genus Malva, of which it the type species. Known as common mallow to English-speaking Europeans, it acquired the common names of cheeses, high mallow and tall mallow (mauve des bois by the French as it migrated from its native home in Western Europe, North Africa and Asia through the English-speaking world.
M. sylvestris is a vigorous plant with showy flowers of bright mauve-purple, with dark veins, standing 0.91–1.22 metres (3–4 ft) high and growing freely in meadows, hedgerows and in fallow fields.

17-4-2018 CHOBE RIVER, BOTSWANA - WHITE HEADED LAPWING (Vanellus albiceps)


The White-crowned Lapwing, also known as the White-headed Lapwing, White-headed Plover, or White-crowned Plover, is a medium-sized wader that presents a striking appearance. Its upper body is adorned with a brown back, while the wings and tail exhibit a bold black and white pattern. The underparts are a clean white. The head is particularly distinctive with a grey base, a brilliant white crown, and a white foreneck. Adding to its unique visage are the yellow eyering, facial wattles, and legs. Both sexes and juveniles share a similar plumage, making them indistinguishable in the field.

When attempting to identify the White-crowned Lapwing, look for the unmistakable combination of its white crown, grey head, and the contrasting black and white patterns on its wings and tail. The yellow eyering and wattles are also key features that aid in its identification.


This species is typically found in tropical Africa, favoring habitats near large rivers. It thrives in areas where sand or shingle is exposed, providing suitable breeding grounds.

The White-crowned Lapwing is a resident bird throughout tropical Africa, maintaining a presence year-round near its preferred riverine environments.

The White-crowned Lapwing is known for its breeding behavior, where it lays 2-3 eggs in a ground scrape near rivers. It is fiercely protective of its nest and young, defending them with vigor against any potential threats, regardless of size. Outside of breeding season, it is common to see these birds feeding in small flocks, where they forage for insects and other small invertebrates.

17-4-2018 CHOBE RIVER, BOTSWANA - EGYPTIAN GOOSE (Alopochen aegyptiaca)


The Egyptian goose, Alopochen aegyptiaca, is a striking bird, native to Sub-Saharan Africa and the Nile Valley. It is a member of the Anatidae family, which includes ducks, geese, and swans. This species is unique in its appearance, resembling a goose more than a duck when in flight, with a heavy and robust stature. Adults typically measure between 63 to 73 centimeters in height.

Both sexes of the Egyptian goose display identical plumage, though males are generally larger. Plumage tones can vary from grey to brown, not necessarily indicative of age or sex. Mature birds boast a significant white patch on their wings, concealed by wing coverts when at rest but prominently displayed when the bird is agitated or in flight.

The Egyptian goose favors open or semi-open environments, often found near freshwater sources. Its habitat ranges from lowlands to high altitudes, such as the Ethiopian Highlands, up to 4,000 meters above sea level. It avoids dense forests and deserts.

This species is widespread and common in its native range, though numbers have dwindled in the northern Nile Valley. Historically found in southeastern Europe and parts of the Middle East, its presence in these areas has diminished.


The Egyptian goose is largely terrestrial, capable of perching on trees and buildings. It is known for its aggressive territorial behavior, especially during breeding season, and is not hesitant to engage in aerial combat with intruders. The species is monogamous, with both parents caring for their offspring.

The male's call is a subdued, hoarse quack, becoming louder and more rapid when agitated, resembling a steam engine. The female's quack is raucous and frequently heard, particularly when defending her young.

Nesting occurs in a variety of locations, with a preference for holes in mature trees. Both parents incubate the eggs, and the young are capable of foraging for themselves shortly after hatching.

Egyptian geese primarily consume seeds, leaves, grasses, and plant stems. They may also eat small animals such as locusts and worms. Goslings initially feed on small aquatic invertebrates before transitioning to grazing.

The Egyptian goose is classified as Least Concern by the IUCN, indicating a stable population. However, in regions where it has been introduced, it is considered invasive and may pose a threat to native species.

17-4-2018 CHOBE RIVER, BOTSWANA - AFRICAN JACANA (Actophilornis africanus)


The African Jacana, Actophilornis africanus, is a distinctive wader known for its remarkable ability to traverse floating vegetation with its elongated toes and claws. This bird exhibits a striking chestnut plumage on its upperparts, complemented by black wingtips, rear neck, and an eyestripe. Adults boast a chestnut underpart, while juveniles display a white underpart with a chestnut belly patch. A blue bill, extending into a coot-like head shield, and grey legs and toes complete its unique appearance.

To identify the African Jacana, look for its long toes and claws, which are adapted for walking on lily pads and other floating vegetation. The adult's chestnut underparts contrast with the juveniles' white underparts and chestnut belly patch. The blue bill with a frontal shield and the bird's size, ranging from 23 to 31 cm in length, are also key identification features.

18-3-2019 BARX, VALENCIA - BROAD LEAVED SWEET PEA (Lathyrus latifolius)


Lathyrus latifolius, the perennial peavine, perennial pea, broad-leaved everlasting-pea, or just everlasting pea, is a robust, sprawling herbaceous perennial flowering plant in the pea family Fabaceae. It is native to Europe but is present on other continents, such as North America and Australia, where it is most often seen along roadsides.

Lathyrus latifolius has winged hairless stems, and alternating blue green compound leaves consisting of a single pair of leaflets and a winged petiole about 2 inches (51 mm) long. The leaflets are narrowly ovate or oblong-ovate, smooth along the margins, hairless and up to 3 in (76 mm) long and 1 in (25 mm) across. There is a branched tendril between the leaflets.

Short racemes of 4–11 flowers are produced from the axils of the leaves. The flowers, which are unscented, are about 3⁄4–1 in (19–25 mm) across with a typical structure for Faboideae, with an upper standard and lower keel, enclosed by lateral petals. There are 5 petals, which are purplish pink, fading with age. There is a green calyx with 5 teeth, often unequal. The blooming period lasts about 2 months during the summer and early autumn.

The flowers are followed by hairless flattened seedpods, about 2 in (51 mm) long and 1⁄2 in (13 mm) wide, with several seeds inside. The seedpod, which is initially green, gradually turns brown, splitting open into curled segments, flinging out the seeds. The seeds are dark and oblong to reniform in shape.

Lathyrus latifolius can reproduce vegetatively from its taproot and rhizomes, or by reseeding.

18-3-2019 BARX, VALENCIA - DWARF MALLOW (Malva neglecta)


Malva neglecta is a species of plant of the family Malvaceae, native to most of the Old World except sub-Saharan Africa. It is an annual growing to 0.6 m (2 ft). It is known as common mallow in the United States and also as buttonweed, cheeseplant, cheeseweed, dwarf mallow, and roundleaf mallow. This plant is often consumed as a food, with its leaves, stalks and seed all being considered edible. This is especially true of the seeds, which contain 21% protein and 15.2% fat.

Dwarf mallow is a prostrate, downy, annual herbaceous plant, growing to approximately 60 cm. The leaves are alternate with long, strongly channeled petioles (up to 12 cm) and narrowly triangular stipules. Each leaf is reniform or with 5–7 shallow lobes, the basal leaves are 3–7 cm. The flowers are single-stalked and occur in clusters of 2–5 in the leaf axils. The flower stalks are shorter than the leaf stalks, with the leaves partially obscuring the flowers. The fruits are schizocarps, which split into 10–12 mericarps (nutlets) and are smooth and hairy.

21-3-2019 MONTE CORONA, VALENCIA - WAVED UMBER MOTH (Menophra abruptaria)

It is found in south-western North Africa, southern Europe and Anatolia; in the north, it is found from England to Switzerland, south-western Germany, Bangladesh . The wingspan is 36–42 mm. Adults are on wing from April to June. Normally, there is one generation per year, although there can be a partial second generation in summer.

The larvae feed on Ligustrum ovalifolium and Syringa vulgaris.

A distinctive species, occurring reasonably commonly in the south of England and Wales, becoming scarcer into the northernmost English counties.

It inhabits woodland, parks and gardens, and flies in a single generation from April into June.

The larvae feed on garden privet (Ligustrum ovalifolium) and lilac (Syringa vulgaris).

21-3-2019 MONTE CORONA, VALENCIA - HOUSE SPARROW (MALE) (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.

18-3-2019 BARX, VALENCIA - THE CICHORIEAE (Tribe Cichorieae)


The Cichorieae (also called Lactuceae) are a tribe in the plant family Asteraceae that includes 93 genera, more than 1,600 sexually reproductive species and more than 7,000 apomictic species. They are found primarily in temperate regions of the Eastern Hemisphere. Cichorieae all have milky latex and flowerheads that only contain one type of floret. The genera Gundelia and Warionia only have disk florets, while all other genera only have ligulate florets. The genera that contain most species are Taraxacum (Crepidinae subtribe) with about 1,600 apomictic species, Hieracium with about 770 sexually reproducing and 5,200 apomictic species, and Pilosella with 110 sexually reproducing and 700 apomictic species (both Hieraciinae). Well-known members include lettuce, chicory, dandelion, and salsify.

Most species are herbaceous, perennial, short-lived or annual plants, rarely subshrubs, shrubs or vines. All Cichorieae-species have latex canals in both the roots, stems and leaves, and this occurs to be a unique character among the Asteraceae, although latex as such occurs rather widespread in this family. The leaves are in a rosette or alternately set along the stem, but this is the dominant situation in the Asteraceae. The only exception in the Cichorieae are the opposite lower leaves of Shinnersoseris. Traditionally, the Cichorieae consisted of taxa with flowerheads only containing bisexual ligulate florets (having a strap-shaped corolla with five teeth at its tip), a rare character that is further present only in the genera Catamixis, Glossarion, Hyaloseris (Mutisieae), and Fitchia (Heliantheae). However, recently the genera Gundelia and Warionia have been included in the Cichorieae, and those two genera have heads containing only disk flowers.

18-3-2019 BARX, VALENCIA - BROAD LEAVED SWEET PEA (Lathyrus latifolius),


Lathyrus latifolius, the perennial peavine, perennial pea, broad-leaved everlasting-pea, or just everlasting pea, is a robust, sprawling herbaceous perennial flowering plant in the pea family Fabaceae. It is native to Europe but is present on other continents, such as North America and Australia, where it is most often seen along roadsides.

The seedpod, which is initially green, gradually turns brown, splitting open into curled segments, flinging out the seeds. The seeds are dark and oblong to reniform in shape.


Lathyrus latifolius can reproduce vegetatively from its taproot and rhizomes, or by reseeding.

Lathyrus latifolius is a perennial herbaceous vine (climber), which can reach 6 feet or more by means of twining tendrils, but in open areas sprawls. It is frost-hardy, long-lived, and slowly spreading. The foliage becomes rather ragged and yellowish by the end of summer.

It requires partial to full sun, and loam or clay-loam soil that is moist, mesic, or slightly dry. Unlike the related annual sweet pea, Lathyrus odoratus, with which it may be confused, it has no scent. While grown as a garden plant it may be pervasive and difficult to remove. Because of this, this species is often considered to be a weed despite its attractive appearance.

Bumblebees pollinate the flowers and butterflies will visit the flowers for their nectar. Epicauta fabricii (Fabricius blister beetle), the caterpillars of Apantesis phyllira (Oithona tiger moth) and some herbivores feed on the leaves. However, the seeds are poisonous.
