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.

20-6-2020 GANDIA, VALENCIA - LITTLE EGRET (Egretta garzetta)
The Little Egret, Egretta garzetta, is a dainty heron adorned in pure white plumage. It is characterized by a slender black beak, long black legs, and, notably in the western race, yellow feet. This elegant bird is a sight to behold with its graceful neck and poised stance.
Adult Little Egrets measure between 55–65 cm in length with a wingspan of 88–106 cm, and weigh 350–550 g. Their plumage is predominantly white, though some may exhibit bluish-grey coloration. Breeding adults boast ornate nape plumes reaching about 150 mm, along with distinctive feathers on the breast and elongated scapulars. The bill and lores are black, with greenish-grey skin at the base of the lower mandible and around the eye, which houses a yellow iris. Legs are black with contrasting yellow feet, though juveniles may have greenish-black legs and duller feet. The subspecies E. g. nigripes is distinguished by yellow skin between the bill and eye, and blackish feet.
The Little Egret frequents a variety of wetland habitats, from the shores of lakes and rivers to marshes and coastal regions. It is often found in open environments, such as mangroves, swamps, mudflats, and sandy beaches, as well as human-altered landscapes like rice fields.
The species has a broad breeding distribution across warm temperate to tropical regions of Asia, Africa, Australia, and Europe. Northern populations are migratory, wintering in Africa and southern Asia, while others remain as permanent residents in warmer areas.

17-6-2020 CREU DE LONGA, 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.

%2020.jpg)
The holly blue (Celastrina argiolus) is a butterfly that belongs to the lycaenids or blues family and is native to the Palearctic.
The holly blue has pale silver-blue wings spotted with pale ivory dots. Seitz describes it "Male above shining violet blue, only the apical portion of the costal margin being minutely edged with white. The female has both wings broadly bordered with dark, the margin of the hindwing bearing vestiges of ocelli. Underside silver-white, in the disc a row of black dots, some of which are elongate, and before the margin blackish shadowy dots. Egg very flat, whitish. Larva green or brown, marked with yellowish white, bearing catenulate (chain-like) stripes on the back, on segment 7 a gland to attract ants; head brown. On Ivy, Ilex, Euonymus, Rhamnus, Robinia, Genista, Spartium, Astragalus, Rubus, Erica, Pyrus and many other plants; in Europe visited usually by ants of the genus Lasius; in June and the autumn. Pupa mostly fastened to the underside of a leaf, ochreous with brown spots and markings. The butterflies in the spring and again in July, occasionally a third time at the end of August and in September, everywhere common, particularly at the flowers of ivy and brambles." In Europe, the first generation feeds mainly on the holly species Ilex aquifolium but the second generation uses a range of food plants.
The holly blue is the national butterfly of Finland.

17-6-2020 CREU DE LONGA, VALENCIA - NORTHERN BANDED GROUNDLING (Brachythemis impartita)
Brachythemis impartita, the Northern banded groundling, is a species of dragonfly, a skimmer from the family Libellulidae from central and northern Africa, its range extending into southern Europe and the Middle East. It was previously considered to be conspecific with B. leucosticta.
Brachythemis impartita has a pale cream pterostigma in both sexes and their eyes appear to be striped. The female has a buffy abdomen and thorax, males are darker and mature males can be dark blue to black on the abdomen and thorax. Males have bands on the outer wings from the node to just short of the pterostigma, this is paler in teneral individuals but darkens as the dragonfly matures.
Where they overlap with B. leucosticta the males can be distinguished by the colour of the veins and the genital lobe, as well as by the ventral structure of segment 8. The females cannot yet be told apart. The length of this dragonfly is from 25 to 34 millimetres (0.98 to 1.34 in) and the span of the hindwings is 20 to 26 millimetres (0.79 to 1.02 in).
Brachythemis impartita is found from central Africa as far south as the Democratic Republic of the Congo and Tanzania north through Africa and to the Mediterranean Sea. Its range also extends into the Middle East where it has been recorded from the Arabian Peninsula, the Levant, Cyprus and southern Anatolia. It has colonised southern Europe and was first recorded there in Portugal in 1957 but it is now also found in Spain, Sardinia, Corsica, Sicily and by 2015 in mainland Italy.
17-6-2020 CREU DE LONGA, VALENCIA - EURASIAN MAGPIE (Pica pica)
%2020.jpg)
The Eurasian magpie, or common magpie (Pica pica), is a striking bird that graces the northern reaches of the Eurasian continent. It is a member of the crow family, known as corvids, and is part of the "monochrome" magpie group within the Holarctic radiation. The bird is easily recognized by its black and white plumage and long, iridescent tail.
Adult Eurasian magpies measure 44–46 cm in length, with over half of this being the tail. They have a wingspan of 52–62 cm. The head, neck, and breast are glossy black with a metallic sheen of green and violet, while the belly and scapulars are pure white. The wings are black with green or purple gloss, and the primaries have white inner webs. The tail is black with green and reddish-purple gloss. Both sexes have similar plumage, though females are slightly smaller.

Little Egrets are social yet territorial when feeding. They exhibit a range of foraging behaviors, from active chasing to patient ambush. Their movements are often in response to the presence of other animals, which may stir up prey.
The Little Egret's vocalizations include croaking and bubbling sounds at breeding colonies and a harsh alarm call when disturbed. These calls are similar to those of the Black-crowned Night Heron and the Cattle Egret.
