31-10-2020 PARCO NATURALE DELLA LESSINIA, ITALY - EURASIAN NUTCRACKER (Nucifraga caryocatactes)
The spotted nutcracker, Eurasian nutcracker, or simply nutcracker (Nucifraga caryocatactes) is a passerine bird slightly larger than the Eurasian jay. It has a much larger bill and a slimmer looking head without any crest. The feathering over its body is predominantly chocolate brown with distinct white spots and streaks (absent from most of the body in southern Asian populations, which are sometimes treated as a separate species, southern nutcracker N. hemispila). The wings and upper tail are virtually black with a greenish-blue gloss.
The spotted nutcracker is one of three currently-recognized species of nutcracker. The Kashmir nutcracker (Nucifraga multipunctata) was formerly considered a subspecies of the spotted. The other member of the genus, Clark's nutcracker (N. columbiana), occurs in western North America.

19-10-2020 SIERRA DE ESPUNA, MURCIA - AOUDAD (Ammotragus lervia)
The Barbary sheep (Ammotragus lervia), also known as aoudad (pronounced [ˈɑʊdæd]) is a species of caprine native to rocky mountains in North Africa. While this is the only species in genus Ammotragus, six subspecies have been described. Although it is rare in its native North Africa, it has been introduced to North America, southern Europe, and elsewhere. It is also known in the Berber language as waddan or arwi, and in former French territories as the moufflon.The Barbary sheep (Ammotragus lervia), also known as aoudad (pronounced [ˈɑʊdæd]) is a species of caprine native to rocky mountains in North Africa.

It is also known in the Berber language as waddan or arwi, and in former French territories as the moufflon.
Barbary sheep stand 75 to 110 cm (2 ft 6 in to 3 ft 7 in) tall at the shoulder, with a length around 1.5 m (5 ft), and weigh 30 to 145 kg (66 to 320 lb).[5] They are sandy-brown, darkening with age, with a slightly lighter underbelly and a darker line along the back. Upper parts and the outer parts of the legs are a uniform reddish- or grayish-brown. Some shaggy hair is on the throat (extending down to the chest in males) with a sparse mane. Their horns have a triangular cross-section. The horns curve outward, backward, then inward, and can exceed 76 cm (30 in) in length. The horns are fairly smooth, with slight wrinkles evident at the base as the animal matures.
23-10-2020 MONTE CORONA, VALENCIA - SPIDER WASP (Family Pompilidae)
Wasps in the family Pompilidae are commonly called spider wasps, spider-hunting wasps, or pompilid wasps. The family is cosmopolitan, with some 5,000 species in six subfamilies. Nearly all species are solitary (with the exception of some group-nesting Ageniellini, and most capture and paralyze prey, though members of the subfamily Ceropalinae are kleptoparasites of other pompilids, or ectoparasitoids of living spiders.
In South America, species may be referred to colloquially as marabunta or marimbondo, though these names can be generally applied to any very large stinging wasps. Furthermore, in some parts of Venezuela and Colombia, it is called matacaballos, or "horse killers", while in Brazil some particular bigger and brighter species of the general marimbondo kind might be called fecha-goela/cerra-goela, or "throat locker".
Like other strong fliers, pompilids have a thorax modified for efficient flight. The metathorax is solidly fused to the pronotum and mesothorax; moreover, the prothorax is best developed in Pompilidae and Scoliidae because wasps in these families use their forelegs to dig.
Pompilids typically have long, spiny legs; the hind femur is often long enough to reach past the tip of the abdomen. The tibiae of the rear legs usually have a conspicuous spine at their distal end. The first two segments of the abdomen are narrow, giving the body a slender look. The pompilid body is typically dark (black or blue, sometimes with metallic reflections), but many brightly colored species exist. From a lateral view, its pronotum looks rectangular and it extends back to the tegulae, near the base of the wings. Most species are macropterous (having long wings), but a few brachypterous (short-winged) and apterous (no wings) species are known.
Spider wasps are best distinguished from other vespoid wasps in having (in most species) a transverse groove bisecting the mesopleuron (the mesepisternal sclerite, a region on the side of middle segment of the thorax above the point where the legs join). They have antennae with 10 flagellomeres in females and 11 in males. Most Pompilidae have straight inner eye margins. The hind wings do not have a distinct claval lobe, but they have a distinctive jugal lobe. The hind leg has a tibial spur with a tuft or row of fine hairs. The legs are long and slender with the tips of the tibia (metatibia) long enough to extend beyond the tip of the abdomen (metasoma). Sexual dimorphism is not pronounced, although females are often larger than the males. Coloration and wing appearance vary greatly among the many species. General coloration is aposematic (warning off predators), generally based on black, often with markings of orange, red, yellow, or white. Larvae can also be identified by physical examination.

22-10-2020 SIERRA DE ESPUNA, MURCIA - COMMON REDSTART (Phoenicurus phoenicurus)
The common redstart (Phoenicurus phoenicurus), or often simply redstart, is a small passerine bird in the genus Phoenicurus. Like its relatives, it was formerly classed as a member of the thrush family, (Turdidae), but is now known to be an Old World flycatcher (family Muscicapidae).
The Common Redstart shows some affinity to the European Robin in many of its habits and actions. It has the same general carriage, and chat-like behaviour, and is the same length at 13–14.5 cm long but slightly slimmer and not quite as heavy, weighing 11–23 g. The orange-red tail, from which it and other redstarts get their names ("start" is an old word for "tail"), is frequently quivered. Among common European birds, only the Black Redstart (Phoenicurus ochrurus) has a similarly coloured tail.
The male in summer has a slate-grey head and upperparts, except the rump and tail, which, like the flanks, underwing coverts and axillaries are orange-chestnut. The forehead is white; the sides of the face and throat are black. The two central tail feathers are dark brown, the other tail feathers bright orange-red. The wings are grey-brown in male P. p. phoenicurus but the remiges have white outer webs forming a pale to whitish wing-patch in adult male P. p. samamisicus (see Taxonomy and systematics). The orange on the flanks shades to almost white on the belly. The bill and legs are black. In autumn, pale feather fringes on the body feathering obscure the colours of the male, giving it a washed-out appearance. The female is grey-brown above and buff-white or light orange below. In most females the throat is whitish, but some (older?) females show a dark bib, some even approaching males in appearance. In P. p. samamisicus, many females tend to show a light wing-patch, analogous to the males but much less prominent.
