24-6-2020 MUNTANYETA DEL SANS, VALENCIA - GREY HERON (Ardea cinerea)
The Grey Heron (Ardea cinerea) is a statuesque wading bird belonging to the family Ardeidae. It is a familiar sight in both rural and urban settings, often seen standing stoically along the water's edge. An adult Grey Heron is a large bird, reaching up to 100 cm in height, with a wingspan between 155 to 195 cm. It weighs between 1 to 2 kg. The plumage is predominantly ashy-grey above, with a greyish-white underbelly and some black on the flanks. A striking feature is the white head and neck adorned with a broad black stripe that extends from the eye to the black crest. The beak is pinkish-yellow, long, and sharply pointed, while the legs are a brown hue.
When identifying the Grey Heron, look for the white head with the black supercilium and crest, the long grey neck, and the ashy-grey wings and back. The underparts are lighter, and the legs are long and brown. Juveniles can be distinguished by their duller grey neck and smaller crest. The beak is a useful indicator of age, being brighter in breeding adults.
Grey Herons are highly adaptable and can be found in a variety of watery habitats including lakes, rivers, ponds, marshes, and coastal environments. They require shallow waters for foraging or areas with shelving margins where they can wade.
Native to temperate Europe and Asia, as well as parts of Africa, the Grey Heron has a broad range. Northern populations may migrate southwards in autumn, while others remain resident year-round. Vagrant sightings have occurred in the Caribbean, Bermuda, and parts of North America.
The Grey Heron exhibits a slow, deliberate flight with its neck retracted in an S-shape. It is known for its solitary foraging habits, often standing motionless or stalking prey through shallow waters. It is also a communal rooster, often found in trees or cliffs at night.
The primary call of the Grey Heron is a loud croaking "fraaank." At breeding colonies, a variety of guttural and raucous noises can be heard, including greeting calls between mates and alarm calls when predators are nearby.
Breeding takes place in colonies, or heronries, typically in high trees near water. Nests are reused and added to each year. The breeding season sees a clutch of three to five bluish-green eggs laid, which both parents incubate. Chicks fledge at 7-8 weeks old.
The Grey Heron can be confused with the larger North American Great Blue Heron or the South American Cocoi Heron. However, it can be distinguished by its size and the coloration of its flanks and thighs.
Grey Herons are apex predators within their ecosystem, feeding on a variety of aquatic creatures such as fish, amphibians, crustaceans, and insects. They have also been known to consume small mammals and juvenile birds.
The Grey Heron is classified as Least Concern by the IUCN, indicating a stable and widespread population.
24-6-2020 RIVER JUCAR, RIOLA, VALENCIA - GREAT CRESTED GREBE (Podiceps cristatus)
%2020.jpg)
The great crested grebe, Podiceps cristatus, is a water bird of the grebe family, notable for its striking black and white plumage and elaborate courtship displays. It is the largest grebe species found in the Old World, with some larger species in the Americas.
Adults are unmistakable in summer with ornate head and neck decorations. In winter, they are whiter than most grebes, with a distinctive white above the eye and a pink bill. Juveniles can be identified by their black and white striped heads, which they lose upon reaching adulthood.
This species prefers vegetated areas of freshwater lakes for breeding.
The great crested grebe has three subspecies: P. c. cristatus in Eurasia, P. c. infuscatus in Africa, and P. c. australis in Australia, Tasmania, and the South Island of New Zealand. The European subspecies migrates from colder regions, while the African and Australasian subspecies are mainly sedentary.
The great crested grebe is an excellent swimmer and diver, pursuing fish underwater. Its mating display is particularly elaborate, involving synchronized dances and poses.
%2021.jpg)
The call of the great crested grebe is a loud barking "rah-rah-rah," complemented by a clicking "kek" and deep growls.
Both sexes build the nest at the water's edge, and the average clutch consists of four chalky-white eggs. Incubation is shared, starting with the first egg and lasting 27 to 29 days. The precocial young are capable of swimming and diving almost immediately and are taught by the adults.
Their diet mainly consists of fish, supplemented by small crustaceans, insects, small frogs, and newts.
The great crested grebe is listed as Least Concern by the IUCN. Conservation efforts in places like New Zealand's Lake Wānaka have been ongoing since 2013. The species has also been a beneficiary of early protection efforts by the Royal Society for the Protection of Birds in the United Kingdom.

23-6-2020 MONTE CORONA, VALENCIA - MOORISH GECKO (Tarentola mauritanica)
Tarentola mauritanica, known as the common wall gecko, is a species of gecko (Gekkota) native to the western Mediterranean area of North Africa and Europe. It has been introduced to Madeira and Balearic Islands, and the Americas (in Montevideo, Buenos Aires and California). A nocturnal animal with a predominantly insectivorous diet, it is commonly observed on walls in urban environments in warm coastal areas; it can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as an insect hunter.
A robust species, up to 15 centimetres (5.9 in) long, its tubercules are enlarged and give the species a spiny armoured appearance.
The species was first described by Carl Linnaeus in 1758. It is also known as moorish gecko, crocodile gecko, European common gecko, and, regionally, as osga (in Portuguese), salamanquesa (in Spanish) and dragó (in Catalan).

22-6-2020 ALFAUIR, VALENCIA - SPOTTED FLYCATCHER (Muscicapa striata)
%2020.jpg)
The Spotted Flycatcher, Muscicapa striata, is a modestly adorned yet charming small passerine bird belonging to the Old World flycatcher family. It is a migratory species, breeding across Europe and the Palearctic as far as Siberia, and spending the winter months in Africa and southwestern Asia. Despite its widespread presence, there is concern over its decline in certain areas.
Adult Spotted Flycatchers possess grey-brown upperparts and a somewhat pallid underbelly. Their crown and breast are streaked, which is the origin of their common name. They have short, black legs and a black bill shaped to suit their insectivorous diet. Juveniles can be distinguished by their browner plumage and the presence of spots on their upperparts.
These birds favor deciduous woodlands, parks, and gardens, particularly those with open spaces amidst trees.
The Spotted Flycatcher has a broad breeding range, extending from Europe to western Siberia and northwest Africa. During the non-breeding season, they migrate to southern Africa.
22-6-2020 ALFAUIR, VALENCIA - EUROPEAN SERIN (MALE) (Serinus serinus)
%20(Serinus%20serinus)%2020.jpg)
The European serin, or simply the serin (Serinus serinus), is a diminutive member of the finch family, Fringillidae. This sprightly bird is the smallest within its family, closely related to the Atlantic canary. It is characterized by its short tail and a length that spans a mere 11 to 12 centimeters. The serin's plumage is a tapestry of nature's palette, with upper parts dappled in dark-streaked greyish green and a conspicuous yellow rump. The underparts are a canvas of yellow breast and white belly, both adorned with heavy streaks.
When attempting to identify the European serin, look for the male's radiant yellow face and breast, which stand out against the greenish backdrop of its feathers. The male also boasts yellow wing bars and yellow tail sides, which can be quite helpful in distinguishing it from similar species. Both sexes share a buzzing trill of a song that resonates through their Mediterranean habitats.
The European serin is partial to open woodland and cultivated areas, often with a sprinkling of conifers. These environments provide the perfect backdrop for breeding and foraging.
This species has a breeding range that extends across southern and central Europe and into North Africa. Populations along the southern and Atlantic coasts tend to be resident, while those in the north are migratory, seeking warmer climates in southern Europe during the winter months.
22-6-2020 ALFAUIR, VALENCIA - MEXICAN PALO VERDE TREE (Parkinsonia aculeata)
%2020.jpg)
Parkinsonia aculeata is a species of perennial flowering tree in the pea family, Fabaceae. Common names include palo verde, Mexican palo verde, Parkinsonia, Jerusalem thorn, jelly bean tree, palo de rayo, and retama.
Parkinsonia aculeata may be a spiny shrub or a small tree. It grows 2 to 8 m (6.6 to 26.2 ft) high, with a maximum height of 10 metres (33 ft). Palo verde may have single or multiple stems and many branches with pendulous leaves. The leaves and stems are hairless. The leaves are alternate and pennate (15 to 20 cm long). The flattened petiole is edged by two rows of 25–30 tiny oval leaflets; the leaflets are soon deciduous in dry weather (and during the winter in some areas) leaving the green petioles and branches to photosynthesize.
The branches grow double or triple sharp spines 7–12 mm (0.28–0.47 in) long at the axils of the leaves. The flowers are yellow- orange and fragrant, 20 mm (0.79 in) in diameter, growing from a long slender stalk in groups of eight to ten. They have five sepals and five petals, four of them clearer and rhomboid ovate, the fifth elongated, with a warmer yellow and purple spots at the base. The flowering period is in the middle months of spring (March–April or September–October). The flowers are pollinated by bees. The fruit is a seedpod, leathery in appearance, light brown when mature.
P. aculeata is a major invasive species in Australia, as it is listed as a Weed of National Significance and is ranked as Australia's worst weed. It is also a major problem in parts of tropical Africa, Hawaii, and other Islands in the Pacific Ocean.
22-6-2020 MONTE CORONA, VALENCIA - SIERRA NEVADA OCELLATED LIZARD (Timon nevadensis)
Timon nevadensis, the Sierra Nevada lizard, is a species of lizard in the family Lacertidae. It is endemic to Spain. It is sometimes considered a subspecies of the ocellated lizard.
Formerly, Timon nevadensis had been regarded as subspecies of Timon lepidus but it has been put into species rank in 2013. Its distribution range is limited to the Sierra Nevada and the Spanish east coast, reaching the Alicante Province in the north.
The Sierra Nevada Ocellated Lizard is an impressive but terribly shy Lacertid. In particular, adult specimens may have flight distances of more than 20 meters. These lizards occur in high altitude mountain areas as well as in coastal dunes and agricultural land.
Adult specimens differ from Timon lepidus by the grey or brown basic coloration with no or reduced black markings.
Juveniles and subadults of Timon nevadensis frequently show dark edges on the labial scales which lack in juvenile Timon lepidus. However, there seem to exist populations with intermediate characteristics.
Within its distribution range, Timon nevadensis cannot be confused with other lizards, due to its big size of adults and the distinct white spot pattern of the juveniles.
These lizards were a regular visitor to our garden but since the large fire in the area we have not seen them for several years. They are sorely missed.
22-6-2020 MAINE, USA - ATLANTIC PUFFIN (Fratercula arctica) WEB CAM
Atlantic Puffins (Fratercula arctica) are small, 25-30 cm seabirds known as "sea parrots" or "clowns of the sea" for their colorful, triangular beaks. They spend winters at sea and gather in large North Atlantic colonies to breed in grassy cliff burrows. These skilled divers reach depths of 60 meters, holding over a dozen fish at once.

21-6-2020 MONTAVERNER, VALENCIA - SOUTHERN GATEKEEPER BUTTERFLY (Pyronia cecilia)
%2020.jpg)
Pyronia cecilia, the southern gatekeeper, is a butterfly of Southern Europe and North Africa. It is a member of the subfamily Satyrinae in the family Nymphalidae.
It is similar in appearance to the gatekeeper (P. tithonus), which is found further north, and the Spanish gatekeeper (P. bathsheba). The gatekeeper has spots on the underside of the hindwing which the southern gatekeeper lacks. The Spanish gatekeeper has quite a different underwing pattern with a prominent while band.
The southern gatekeeper, like many in subspecies Satyrinae, exhibits sexual dimorphism. The male is smaller than the female, the front wing of the male is 15 to 16 mm whereas a female front wing is 20 mm, and has a patch of scent-producing scales known as the androconia, which can be seen as a dark patch on the upperside of the forewing.
The southern gatekeeper likes hot localities and is found in northern Africa and southern Europe; in Tunisia, Algeria, Morocco, Portugal, Spain including Mallorca and Menorca, south-eastern France, Corsica, Sardinia, Elba, Italy, Sicily, Croatia, Albania, Greece and Turkey. It is usually found in rough, open areas in lowland regions although in some areas it occurs up to 2,000 m (6,600 ft).
Food plants are grasses including Deschampsia cespitosa

29-3-2018 OUDTSCHOORN, SOUTH AFRICA - CAPE WEAVER (Ploceus capensis)
%2040-topaz-upscale-1.5x.jpg)
The Cape weaver, Ploceus capensis, is a robust bird, measuring 17 cm in length, with olive-brown streaked upperparts and a sharply pointed conical bill. This species exhibits sexual dimorphism.
During the breeding season, the male Cape weaver is resplendent with a bright yellow head and underparts, an orange visage, and striking white irises. The adult female, however, sports an olive-yellow head and breast, which fades to a paler yellow on the lower belly. While females typically have brown eyes, a small percentage may display pale eyes during the summer months. Juveniles resemble the female in plumage.
The Cape weaver thrives in open grasslands, lowland fynbos, coastal thickets, and agricultural landscapes, provided there is a consistent presence of water and suitable trees for nesting.
This bird is endemic to the southern reaches of Africa, specifically South Africa, Lesotho, and Eswatini. Its range extends from the Northern Cape's Orange River, southward to the Cape of Good Hope, and eastward to northern KwaZulu Natal, almost reaching Bloemfontein in the Free State.
Outside of the breeding season, Cape weavers form flocks and congregate in large communal roosts, which may be shared with other avian species. They exhibit anting behaviour and are known to bathe even during rainfall or mist.
