13-1-2021 CREU DE LONGA, VALENCIA - GREAT EGRET (Ardea alba)
Great Egrets usually stay in habitats that have areas of either saltwater or freshwater nearby. They are seen near marshes, ditches, canals, ponds, tidal flats, rivers, streams, swamps, lakes, estuaries (or water passages where the ocean tide meets a river current), and flooded farm fields. Great Egrets are usually solitary birds when not nesting. But they also can gather together from surrounding areas to form a place where a large group can rest or sleep, called a communal roost. Frequently, several pairs build nests in the same tree and form a colony; but occasionally a pair may nest alone. Great Egrets often share colonial nesting sites, or rookeries, with other egret species, herons, and other wading birds as well.
They build their nests in trees, thickets, or shrubs 10-90 feet above water or ground. Nesting colonies are usually located in extremely tall trees. Great Egrets build large platform-style nests using sticks and line the nests with plant material. Both parents help to build the nest, incubate (to sit on and keep the eggs warm) the eggs, and feed their young. The young will be able to fly in 6-7 weeks after hatching.
Within the colony, Great Egrets are territorial and aggressive, defending their space with sharp bill jabs and harsh calls.
The great egret is generally a very successful species with a large and expanding range, occurring worldwide in temperate and tropical habitats. It is ubiquitous across the Sun Belt of the United States and in the Neotropics. In the Nordic countries, it was historically a rare visitor.
13-1-2021 MUNTANYETA DEL SANTS, VALENCIA - WATER PIPIT (Anthus spinoletta)

They are short-distance migrants, construct cup-shaped nests, and feed on various small invertebrates picked off the ground or vegetation.
Adult Water pipits in spring plumage have greyish-brown upperparts, weakly streaked with darker brown, and pale pink-buff underparts fading to whitish on the lower belly. There may be some faint streaking on the breast and flanks. Their head is grey with a broad white supercilium. The outer tail feathers are white, and the legs, bill and iris are dark brown or blackish. In non-breeding plumage, the head is grey-brown and the supercilium is less distinct. The upperparts are more streaked, and the underparts are white, marked lightly with brown on the breast and flanks.
The sexes are similar although the female has, on average, a greyer head. Young birds resembles the non-breeding adult, but are browner and more streaked above with prominent streaking on the underparts.

Water pipits breed in the mountains of southern Europe and Asia from Spain to central China, along with the Mediterranean islands of Sardinia and Corsica. These birds migrate relatively short distances; some populations winter mainly in western and southern Europe and in northwestern Africa; in western Europe some birds show fidelity to the same wintering site, returning each year.
Birds in Spain move only lower down the mountains in which they breed. Others winter at lower altitudes near their breeding areas and also in the Arabian Peninsula and northeast Africa. Some birds winter in Pakistan, northwest India, and southern China. Water pipits breed in alpine pastures and high meadows with short grass and some bushes or rocks. They are typically found close to wetter areas and often on slopes. Wintering grounds typically include coastal wetlands, marshes, rice fields, and similar habitats.
