4-5-2018 ULAL DE BOLDOVI, VALENCIA - GULL BILLED TERN (Gelochelidon nilotica)
The gull-billed tern (Gelochelidon nilotica), formerly Sterna nilotica, is a tern in the family Laridae. It is widely distributed and breeds in scattered localities in Europe, Asia, northwest Africa, and the Americas. The Australian gull-billed tern was previously considered a subspecies.
This is a fairly large and powerful tern, similar in size and general appearance to a Sandwich tern, but the short thick gull-like bill, broad wings, long legs and robust body are distinctive. The summer adult has grey upperparts, white underparts, a black cap, strong black bill and black legs. The call is a characteristic ker-wik. It is 33–42 cm (13–17 in) in length and 76–91 cm (30–36 in) in wingspan. Body mass ranges from 150–292 g (5.3–10.3 oz).
In winter, the cap is lost, and there is a dark patch through the eye like a Forster's tern or a Mediterranean gull. Juvenile gull-billed terns have a fainter mask, but otherwise look much like winter adults.

The prong-billed barbet (Semnornis frantzii) is a distinctive, relatively large-billed bird native to humid highland forest of Costa Rica and western Panama.
The prong-billed barbet is found in the mountains from Costa Rica's Cordillera de Tilarán to western Panama's Veraguas Province. In elevation it mostly ranges between 750 and 2,450 m (2,500 and 8,000 ft) on the Caribbean side of Costa Rica, between 1,500 and 1,450 m (4,900 and 4,800 ft) on the Pacific side, and between 1,500 and 2,250 m (4,900 and 7,400 ft) in Panama. (Locally it occurs somewhat lower in both countries.) It inhabits the interior and edges of extremely humid montane evergreen forest, a landscape characterized by many epiphytes and mosses and frequent fog.

The emerald toucanet is non-migratory.
The emerald toucanet is gregarious and frequently gathers in groups of up to about 10.

The emerald toucanet's breeding season is from March to July. It nests in tree cavities, either natural or those abandoned by woodpeckers. They can be as high as 27 m (89 ft) above the ground. The typical clutch size is three or four but can range from one to five. Both sexes incubate the eggs but the female does so more than the male. The incubation period is 16 days and fledging occurs 42 to 45 days after hatch.

15-4-2019 MONTE CORONA, VALENCIA - HELICINAN SLUG (Infraorder Arionoidei)
Limacus flavus, known commonly as the cellar slug, the yellow slug, or the tawny garden slug, is a medium to large species of air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Limacidae.
This slug has a yellow body with grey mottling, and pale blue tentacles. When extended, the body length can be 7.5 to 10 cm (3.0 to 3.9 in).
The yellow slug is common in Scotland, England, Wales and Ireland as well as most of southern and western Europe. It has been accidentally introduced in many other parts of the world.
Yellow slugs, like the majority of other land slugs, use two pairs of tentacles on their heads to sense their environment. The upper pair, called optical tentacles, is used to sense light. The lower pair, oral tentacles, provide the slug's sense of smell. Both pairs can retract and extend themselves to avoid hazards, and, if lost to an accident or predation, can be regrown.
Like all slugs, the yellow slug moves relatively slowly, gliding along using a series of muscular contractions on the underside of its foot, which is lubricated with mucus, such that it leaves a slime trail behind it.
This species feeds mostly on fungi, decaying matter, and vegetables.
This species is strongly associated with human habitation, and is usually found in damp areas such as cellars, kitchens, and gardens or under stones. Generally speaking it is only seen at night, because it is nocturnal. Thus often it goes unnoticed and people are unaware of how (relatively) common the species is.
