%2010-gigapixel-scale-1_4x.jpg){kind=tracking}
The black-throated mango (Anthracothorax nigricollis) is a species in subfamily Polytminae of the hummingbird family Trochilidae. It is found in Panama, in every mainland South American country except Chile, and on Trinidad and Tobago.
%2020-gigapixel-scale-1_4x.jpg){kind=tracking}
The nominate subspecies of the black-throated mango is found from western Panama into much of Colombia and Venezuela, the Guianas, eastern Ecuador and Peru, northern and eastern Bolivia, eastern Paraguay, far northern Argentina, most of Brazil, and on both Trinidad and Tobago. It has also occurred as a vagrant in Uruguay. Subspecies A. n. iridescens is found in extreme southwestern Colombia, western Ecuador, and extreme northwestern Peru.
The black-throated mango inhabits a variety of landscapes in the lowland tropics, most of them semi-open to open. These include gallery forest, shade coffee and cacao plantations, the edges of dense forest, and parks and gardens in populated areas. In general it is a bird of the lowlands, but reaches 1,400 m (4,600 ft) in Venezuela, 1,700 m (5,600 ft) in Colombia, and 2,000 m (6,600 ft) in eastern Brazil.
16-4-2020 MONTE CORONA, VALENCIA - BLUE ROCK THRUSH (MALE) (Monticola solitarius)
%20(Monticola%20solitarius)%2020.jpg)
The blue rock thrush (Monticola solitarius) is a chat species, reminiscent of a thrush, with a starling-like stature, measuring 21–23 cm in length. The male of the nominate subspecies is predominantly blue-grey, save for darker wings, presenting a striking appearance. Females and immature birds are less vivid, with dark brown upperparts and paler, scaly brown underparts. The male of the subspecies M. s. philippensis is distinguished by rufous-chestnut plumage from the mid-breast to the undertail, a feature absent in both sexes of the rock thrush.
To identify the blue rock thrush, look for the male's unmistakable blue-grey plumage and the female's less conspicuous brown tones. The male M. s. philippensis can be recognized by its rufous-chestnut lower half. Both sexes lack the reddish outer tail feathers seen in rock thrushes.
This bird favors open, mountainous regions where it can nest in rock cavities and walls.
%20(Monticola%20solitarius)%2021.jpg)
The blue rock thrush breeds across southern Europe, northwest Africa, and from Central Asia to northern China and Malaysia. It is a resident bird in Europe, north Africa, and southeast Asia, with some populations exhibiting altitudinal migration. Other Asian populations are migratory, wintering in sub-Saharan Africa, India, and southeast Asia. It is a rare visitor to northern and western Europe.
The blue rock thrush is an omnivore, consuming a varied diet of insects, small reptiles, berries, and seeds. It breeds in its preferred mountainous habitats, laying 3-5 eggs per clutch.
The male's song is a clear and melodious call, louder than that of the rock thrush, which can be heard echoing through its mountainous domain.
As an omnivore, the blue rock thrush has a diverse diet that includes insects, small reptiles, berries, and seeds.
The blue rock thrush is currently listed as Least Concern on the IUCN Red List, indicating that it is not at immediate risk of population decline.
16-4-2020 MONTE CORONA, VALENCIA - DOUBLE STRIPED PUG MOTH (Gymnoscelis rufifasciata)
%2020.jpg)
The double-striped pug (Gymnoscelis rufifasciata) is a moth of the family Geometridae. It is a widespread and common species, being found throughout the Palearctic region, including the Near East and North Africa.
This is a variable species but always easy to recognize due to the two prominent dark fascia across each forewing which give the species its common name. The forewing ground colour ranges from light to dark reddish brown. The crosslines are distinct. The inner margin of the pale white sub-marginal line bears black marks. The hindwings are pale grey with darker fringes, darker lines and a small black discal spot. There is a dark band across the basal segments of the abdomen. The wingspan is 15–19 mm.
The caterpillars reach a length of up to 17 millimeters and have a very variable basic colouration. It ranges from whitish to yellowish green, brown, red to purple. On the back there is a pale band marked with a series of dark diamonds or triangles. The drawing resembles a rear-facing trident, is sometimes crow-foot-like and can occasionally be only weakly formed. The head is yellowish brown.
Two, sometimes three, broods are produced each year and the adults are on the wing in April and May (sometimes earlier), July and August, and sometimes later in the autumn. Later broods are more heavily marked. It flies at night and is attracted to light and flowers, both of its food plants and others.
The larva feeds on the flowers of a huge range of plants (see list below) and has also been known to feed on the larvae of other lepidoptera. The species overwinters as a pupa.
16-4-2020 MONTE CORONA, VALENCIA - CURVED HORN MOTH (Superfamily Gelechioidea)
Curved-horn moths (superfamily Gelechioidea) are a massive, diverse group of primarily "micro-moths" comprising 15–21 families and over 18,000 described species worldwide. Defined by their distinct,, up-curved labial palps, they occupy varied habitats as leaf miners, case-bearers, or pests, with many larvae feeding on plants, fungi, or stored products.
Key Facts About Curved-Horn Moths (Gelechioidea)
Distinctive Appearance: The name comes from their well-developed, upward-curved labial palps, which resemble horns. They are generally small ("micro-moths").
Massive Diversity: With over 18,000 described species, it is one of the largest Lepidoptera superfamilies, and experts estimate only 25% of their total diversity has been described.
Etymology: The name Gelechioidea is derived from the type genus Gelechia, meaning "resting on the ground".
Ecological Roles & Habitats: They inhabit a wide range of terrestrial and aquatic habitats. Their larvae act as miners (in leaves, stems, or seeds), case-bearers, gall-makers, and scavengers.
Agricultural Impact: Several species are significant pests, including the potato tuber moth (Phthorimaea operculella), tobacco stem borer (Scrobipalpa aptatella), and white-shouldered house moth (Endrosis sarcitrella).
Key Families Included: The superfamily contains a diverse array of families, including:
Gelechiidae: Twirler moths.
Coleophoridae: Case-bearers.
Oecophoridae: Concealer moths.
Blastobasidae: iNaturalist.
Scythrididae: Flower moths.
Elachistidae: Grass-miner moths.
Scientific Significance: They are a basal lineage of the Ditrysia clade and are crucial for studying insect evolution and diversity.

16-4-2021 GREAT SPIRIT BLUFF CAM, MINNESOTA - NORTH AMERICAN PEREGRINE FALCON (Falco peregrinus ssp. anatum)
The peregrine falcon (Falco peregrinus), also known simply as the peregrine, and historically as the duck hawk in North America, is a cosmopolitan bird of prey (raptor) in the family Falconidae. A large, crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed. It can reach over 320 km/h (200 mph) during its characteristic hunting stoop (high-speed dive), making it the fastest member of the animal kingdom. According to a National Geographic TV program, the highest measured speed of a peregrine falcon is 389 km/h (242 mph). As is typical for bird-eating (avivore) raptors, peregrine falcons are sexually dimorphic, with females being considerably larger than males.
The peregrine's breeding range includes land regions from the Arctic tundra to the tropics. It can be found nearly everywhere on Earth, except extreme polar regions, very high mountains, and most tropical rainforests; the only major ice-free landmass from which it is entirely absent is New Zealand. This makes it the world's most widespread raptorand one of the most widely found bird species. In fact, the only land-based bird species found over a larger geographic area is not always naturally occurring, but one widely introduced by humans, the rock pigeon, which in turn now supports many peregrine populations as a prey species.
The peregrine is a highly successful example of urban wildlife in much of its range, taking advantage of tall buildings as nest sites and an abundance of prey such as pigeons and ducks. Both the English and scientific names of this species mean "wandering falcon", referring to the migratory habits of many northern populations. Experts recognize 17 to 19 subspecies, which vary in appearance and range; disagreement exists over whether the distinctive Barbary falcon is represented by two subspecies of Falco peregrinus or is a separate species, F. pelegrinoides. The two species' divergence is relatively recent, during the time of the last ice age, therefore the genetic differential between them (and also the difference in their appearance) is relatively tiny. They are only about 0.6–0.8% genetically differentiated.

23-10-2019 BIOPARC, VALENCIA - HAMERKOP (Scopus umbretta)
The hamerkop (Scopus umbretta), also called the umbrette, is a medium-sized bird. It is the only living species in the genus Scopus and the family Scopidae. The species and family was long thought to sit with the Ciconiiformes but is now placed with the Pelecaniformes, and its closest relatives are thought to be the pelicans and the shoebill. The shape of its head with a long bill and crest at the back is reminiscent of a hammer, which has given this species its name after the Afrikaans word for hammerhead. It is a medium-sized waterbird with brown plumage. It is found in mainland Africa, Madagascar and Arabia, living in a wide variety of wetlands, including estuaries, lakesides, fish ponds, riverbanks, and rocky coasts. The hamerkop is a sedentary bird that often shows local movements.
The hamerkop takes a wide range of prey, mostly fish and amphibians, but shrimps, insects and rodents are taken too. Prey is usually hunted in shallow water, either by sight or touch, but the species is adaptable and will take any prey it can. The species is renowned for its enormous nests, several of which are built during the breeding season. Unusually for a wading bird, the nest has an internal nesting chamber where the eggs are laid. Both parents incubate the eggs and raise the chicks.
The species is not globally threatened and is locally abundant in mainland Africa and Madagascar. The International Union for Conservation of Nature (IUCN) has assessed it as being of least concern.
The hamerkop is a medium-sized waterbird, standing 56 cm (22 in) high and weighing 470 g (17 oz), although the subspecies S. u. minor is smaller. Its plumage is a drab brown with purple iridescence on the back; S. u. minor is darker. The tail is faintly barred with darker brown. The sexes are alike and fledglings resemble adults.[10] The bill is long, 80 to 85 mm (3.1–3.3 in), and slightly hooked at the end. It resembles the bill of a shoebill, and is quite compressed and thin, particularly at the lower half of the mandible. The bill is brown in young birds, but becomes black by the time a bird fledges.
The neck and legs are proportionately shorter than those of similar looking Pelecaniformes. The bare parts of the legs are black and the legs are feathered only to the upper part of the tibia. The hamerkop has, for unknown reasons, partially webbed feet. The middle toe is comb-like (pectinated) like a heron's. Its tail is short and its wings are big, wide, and round-tipped; it soars well, although it does so less than the shoebill or storks. When it does so, it stretches its neck forward like a stork or ibis, but when it flaps, it coils its neck back something like a heron. Its gait when walking is jerky and rapid, with its head and neck moving back and forth with each step. It may hold its wings out when running for extra stability.
The hamerkop occurs in Africa south of the Sahara, Madagascar, and coastal south-west Arabia. It requires shallow water in which to forage, and is found in all wetland habitats, including rivers, streams, seasonal pools, estuaries, reservoirs, marshes, mangroves, irrigated land such as rice paddies, savannahs, and forests. In Tanzania, it has also recently begun to feed on rocky shores. In Arabia, it is found in rocky wadis with running water and trees. Most are sedentary within their territories, which are held by pairs, but some migrate into suitable habitat during the wet season only. The species is very tolerant of humans and readily feeds and breeds in villages and other human-created habitats.
25-11-2015 JURONG, SINGAPORE - COCONUT LORIKEET (richoglossus haematodus)
%2010.jpg)
Coconut Lorikeets are extremely social parrots. They form small to medium-sized flocks that roost and forage together. They are highly vocal and engage in constant communication with their flock members.
Their bright green and red feathers blend in well with the flowering plants they feed upon, but Lorikeet safety also comes from having their flock on the lookout for predators.
These lorikeets have a specialized diet primarily consisting of nectar, pollen, fruits, and flower buds. Their tongue is equipped with unique brush-like bristles that aid in extracting nectar from flowers and licking pollen from plants. They also have a simplified digestive system that helps them quickly extract sugar from the nectar they eat.
During the breeding season, male Coconut Lorikeets display elaborate courtship rituals to attract females. Once a pair has formed a bond, they search for suitable nesting sites. Their nests are typically constructed in tree hollows. The female lays 1 to 3 eggs, which both parents take turns incubating for 24 to 28 days. Chicks then stay in the nest for about 10 weeks until they are old enough to join the flock.
Coconut Lorikeets are considered Least Concern on the IUCN Red List due to their large area. They have even become an invasive species in some areas, where they compete aggressively for tree hollows. Globally their population is decreasing.
%2011.jpg)
Trichoglossus haematodus is found in eastern Indonesia, on Buru, Seram, Misool, Waigeo, Numfoor, Yapen and the Aru Islands, in Indonesia and Papua New Guinea on New Guinea, in the Bismarck Archipelago, the Solomon Islands, Vanuatu and New Caledonia.
The species occupies a wide range of lowland and wooded hill habitats, including mangroves, rainforest, nypa forest, swamps, savanna and woodland. It also occupies human-modified areas including coconut plantations, gardens, agricultural land and disturbed forest. It is found from sea level up to as high as 2,440 m (8,010 ft); this upper altitude level varies by location.

8-5-2017 ARCOS DE FRONTERA, ANDALUSIA - WHITE FACED OWL (Genus Ptilopsis)
%2020.jpg)
Ptilopsis is a genus of typical owls, or true owls, in the family Strigidae, that inhabits Africa. Its members are Northern and Southern White faced owls.
The northern white-faced owl is a species of owl in the family Strigidae. The southern white-faced owl was formerly included in this species and the two were known as the white-faced scops-owl. It is found in a band across Africa between the Sahara and the Equator.
13-4-2020 MONTE CORONA, VALENCIA - THREE BAND SLUG (Genus Ambigolimax)
The Three-banded Garden Slug (Ambigolimax valentianus, formerly Lehmannia valentiana) is a species of land slug known for its distinctive markings and, often, its status as an invasive pest in greenhouses and gardens.
Here are the key facts about Three-banded Slugs:
Physical Characteristics
Appearance: They are usually pale buff, yellowish, or brown with a slightly pinkish tinge.
Markings: They are best recognized by three, often dark, longitudinal bands on the mantle (the "shield" behind the head), with the side bands extending down the body.
Size: Adults typically reach 4–8 cm in length.
Mucus: They produce a clear, watery, and transparent mucus.
Body Features: They have a small, short, or indistinct keel (the ridge running down the center of the tail).

8-5-2017 SEVILLE, ANDALUCIA - 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.
House sparrows are social birds, often seen in flocks. They exhibit a range of behaviors, including dust or water bathing and communal roosting. Males are known to be territorial around their nesting sites.
The house sparrow's vocalizations are predominantly variations of a simple chirping call. Males may sing or give an "ecstatic call" during the breeding season, and the species uses a variety of calls for different social interactions.
House sparrows are generally monogamous and may mate for life. They can breed in the season following their hatching and often produce multiple clutches per year, with each clutch containing up to five eggs. Nest sites are varied, with a preference for cavities.
An opportunistic feeder, the house sparrow's diet consists mainly of seeds from grains and weeds, but it also consumes insects and other invertebrates, especially during the breeding season when feeding young.
Despite its widespread distribution and abundance, the house sparrow has experienced declines in some areas. However, it is currently listed as Least Concern on the IUCN Red List.
