21-7-2021 SANT ISIDRE, VALENCIA - EURASIAN BLACKBIRD (MALE) (Turdus merula)
The Common Blackbird, Turdus merula, is a true thrush and a familiar sight in gardens and woodlands. The male is distinguished by its all-black plumage, bright yellow eye-ring, and orange-yellow bill, which darkens slightly during winter. Females and juveniles are more demure in their attire, sporting mainly dark brown feathers.
Adult males are entirely black with the exception of the yellow eye-ring and bill. Females are sooty-brown with a duller bill, and juveniles resemble females but have pale spots on their upperparts. The very young may also exhibit a speckled breast.
The Common Blackbird thrives in a variety of habitats including woodlands with dense undergrowth, gardens, parks, and hedgerows. It shows a preference for deciduous trees and areas with thick vegetation.
This species is widespread across Europe, western Asia, and North Africa. It has also been introduced to Australia and New Zealand. Its range varies from resident populations in the milder regions to partially or fully migratory populations in areas with more severe winters.
The Common Blackbird is territorial, especially during breeding season, with males displaying distinctive threat behaviors to ward off rivals. Outside of breeding season, they can be more sociable, often forming small flocks. The species is known for its adaptability to urban environments, where it may overwinter more readily than in rural settings.
The male's song is a melodious and fluted warble, often heard from elevated perches during the breeding season. The Common Blackbird also has a repertoire of calls including a sharp "seee" when agitated and a "pook-pook-pook" to signal ground predators.
Monogamous by nature, the Common Blackbird builds a neat, cup-shaped nest, often in dense shrubbery. The female lays three to five bluish-green eggs adorned with reddish-brown blotches. Both parents are involved in feeding the altricial chicks until they fledge.
An omnivore, the Common Blackbird forages primarily on the ground for insects, earthworms, seeds, and berries. It is adept at pulling earthworms from the soil and foraging through leaf litter for other invertebrates.
21-7-2021 RACO DE OLLA, VALENCIA - SPECKLED WOOD BUTTERFLY (Pararge aegeria)
The speckled wood (Pararge aegeria) is a butterfly found in and on the borders of woodland areas throughout much of the Palearctic realm. The species is subdivided into multiple subspecies, including Pararge aegeria aegeria, Pararge aegeria tircis, Pararge aegeria oblita, and Pararge aegeria insula. The color of this butterfly varies between subspecies. The existence of these subspecies is due to variation in morphology down a gradient corresponding to a geographic cline.
The background of the wings ranges from brown to orange, and the spots are either pale yellow, white, cream, or a tawny orange. The speckled wood feeds on a variety of grass species. The males of this species exhibit two types of mate locating behaviors: territorial defense and patrolling. The proportion of males exhibiting these two strategies changes based on ecological conditions. The monandrous female must choose which type of male can help her reproduce successfully. Her decision is heavily influenced by environmental conditions.
21-7-2021 RACO DE OLLA, 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.
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.

20-7-2021 MONTE CORONA, VALENCIA - EUROPEAN PAPER WASP (Polistes dominula)
The European paper wasp (Polistes dominula) is an invasive species, often identified by its slender, black-and-yellow appearance (resembling yellowjackets) and trailing legs during flight. Unlike native species, they build small, open-comb nests in sheltered, dark, and often artificial areas like pipes, eaves, and electrical boxes.
Key Facts about the European Paper Wasp:
Appearance and Identification:
Coloration: Primarily black with bright yellow markings, often mistaken for yellowjackets.Body Shape: Slender with a narrow "waist".Flight: Long hind legs dangle below them while flying.Size: Similar to other paper wasps, but generally more slender.
Behavior and Ecology:Nesting: They build small, open-comb, papery nests made of chewed, saliva-mixed wood fibers.
Habitat: They prefer urban environments, nesting in hidden, dark, or enclosed spaces such as eaves, bird boxes, and utility pipes.Diet: They are predatory, preying on insects, particularly caterpillars, to feed their larvae, and also feed on nectar and fruit.Temperament: They are generally less aggressive than yellowjackets and tend to sting only when their nest is disturbed.

4-4-2018 PHINDA GAME RESERVE, SOUTH AFRICA - NYALA (FEMALE) (Tragelaphus angusii)
Nyala live in groups of up to 10 individuals that may be mixed or may contain only females or only males. Old males usually live alone. Females often remain near their mothers when they have their offspring, so the relationships in female herds may be considered relatively closer than that of males. Herds usually feed and drink water together. Nyala are not territorial animals and the home ranges of males are approximately equal to that of females and overlap extensively. Nyala are active mainly in the early morning and late afternoon. They browse during the day if temperatures are 20-30 °C (68-86 °F) and during the night in the rainy season.
During the hot hours of the day, these antelopes usually rest in thick bushes. They are very shy in nature, and like remaining hidden rather than coming out in the open. Most sightings of nyala in the wild are at water holes. But nowadays they are becoming less shy and often come out in the sight of tourists. Alert and wary in nature, nyala uses a sharp, high, dog-like bark to warn others in a group about the danger. This feature is mainly used by females. They also react to the alarm calls of impala, baboon, and kudu.
18-7-2021 MONTE CORONA, VALENCIA - JASMINE MOTH (Palpita vitrealis)
%2020.jpg)
Palpita vitrealis, common name jasmine moth or white pearl, is a species of moth of the family Crambidae.
This species occurs worldwide, including Africa (Equatorial Guinea, Gambia, Kenya, Sierra Leone, South Africa),Asia, Australia and Europe. In Europe, it is mainly found in southern Europe, but may be found further north.
The wingspan of Palpita vitrealis can reach 27–31 mm. The body and the wings are translucent with a slight sheen. Eyes are large and reddish-brown. On the upper edge of the forewings is present a rather broad orange or brown border. The forewings also show two black spots in the middle. Legs are white and brown ringed.
These moths mainly fly from August till late October, depending on the location. They feed on nectar of various flowers, including ivy and buddleia. This species shows a migratory nature. The larvae are initially yellow, later becoming green. They can grow to a length of about 2 cms. They feed on the leaves of the host plants, mainly jasmine (Jasminum officinale), privet (Ligustrum species), Forsythia, Arbutus unedo and european olive (Olea europaea). In Africa the preferred host plants are Sida rhombifolia, Grewia, Helicteres isora, Schima noronhae and Randia scortechinii. The larvae are considered a pest of olive fields, as they attack the leaves and fruits. The final instar of the larvae spins some leaves together and form a silky cocoon to pupate.

18-7-2021 MONTAVERNER, VALENCIA - WHITE FEATHERLEG DAMSELFLY (Platycnemis latipes)
The white-legged damselfly or blue featherleg (Platycnemis pennipes) is a damselfly of slow-flowing, muddy waters. It occurs from the Atlantic to Siberia and is often abundant throughout its range.
Platycnemis pennipes is about 32 millimetres (1.3 in) long. Mature adults differ from most other blue damselflies in having expanded white edges to the tibiae, paired black markings down most of the abdomen, broad pale brown double antehumeral stripes, wider head and a pale brown pterostigmata.
The male has a blue abdomen that is often pale and usually has a greenish thorax. The female is a very pale yellow-green colour with black markings.
This species favours unshaded slow-flowing sections of muddy rivers with abundant floating vegetation. it has been recorded in tidal rivers and the larvae seem well able to tolerate brackish water. It also occurs in muddy streams but is rare in lakes or ponds of any sort. In north-west Europe, it is mostly confined to flowing waters.
Mating is preceded by the male displaying his white legs in a fluttering display flight in front of females. Elongated eggs are laid whilst in tandem, into emergent stems and especially the underside of floating leaves. The larvae live amongst bottom debris and emerge after two years.
After emerging, adults tend to congregate in the shelter of tall vegetation, although some immatures wander away from water and have been found five kilometres away from the nearest breeding site.
