Griffon Vulture (grifo)

Scientific name: Gyps fulvus

Monfrague National Park (Spain)

Grifo – Parque Nacional de Monfrague (Espanha)

The Griffon Vulture (Gyps fulvus) is a large Old World vulture in the bird of prey family Accipitridae.

The Griffon Vulture is 93–110 cm (37–43 in) long with a 230–280 cm (91–111 in) wingspan; it weighs between 6 and 13 kg (13.2 and 29 lb). Hatched naked, it is a typical Old World vulture in appearance, with a very white bald head, very broad wings and short tail feathers. It has a white neck ruff and yellow bill. The buff body and wing coverts contrast with the dark flight feathers.

Like other vultures, it is a scavenger, feeding mostly from carcasses of dead animals which it finds by soaring over open areas, often moving in flocks. It grunts and hisses at roosts or when feeding on carrion.

Little is known about the average life-span of these birds. It is approximated at 50 to 70 years in the wild, but the oldest death recorded in captivity is 118 years old.[2]

It breeds on crags in mountains in southern Europe, north Africa, and Asia, laying one egg. Griffon Vultures may form loose colonies. The population is mostly resident.

Mute Swan (Cisne-mudo)

Scientific name: Cignus Olor

Cisne-mudo – Parque da Cidade

The Mute Swan (Cygnus olor) is a species of swan, and thus a member of the duck, goose and swan family Anatidae. It is native to much of Europe and Asia, and (as a rare winter visitor) the far north of Africa. It is also an introduced species in North America, Australasia and southern Africa. The name ‘mute’ derives from it being less vocal than other swan species.Measuring 125 to 170 centimetres in length, this large swan is wholly white in plumage with an orange bill bordered with black. It is recognisable by its pronounced knob atop the bill

Mandarin Duck (Pato-mandarim)

Scientific name: Aix galericulata

Pato-mandarim  – Parque da Cidade

The Mandarin Duck (Aix galericulata), or just Mandarin, is a medium-sized perching duck, closely related to the North American Wood Duck. It is 41–49 cm long with a 65–75 cm wingspan.

The adult male is a striking and unmistakable bird. It has a red bill, large white crescent above the eye and reddish face and “whiskers”. The breast is purple with two vertical white bars, and the flanks ruddy, with two orange “sails” at the back. The female is similar to female Wood Duck, with a white eye-ring and stripe running back from the eye, but is paler below, has a small white flank stripe, and a pale tip to its bill.

Unlike other species of ducks, most Mandarin drakes reunite with the hens they mated with along with their offsprings after the eggs have hatched and even share scout duties in watching the ducklings closely. However, even with both parents securing the ducklings, most of them do not survive to adulthood.

The species was once widespread in eastern Asia, but large-scale exports and the destruction of its forest habitat have reduced populations in eastern Russia and in China to below 1,000 pairs in each country; Japan, however, is thought to still hold some 5,000 pairs

European Robin (Pisco-de-peito-ruivo)

Scientific name: Erithacus rubecula

Pisco-de-peito-ruivo  – Parque da Cidade

The European Robin (Erithacus rubecula), most commonly known in Anglophone Europe simply as the Robin, is a small insectivorous passerine bird that was formerly classed as a member of the thrush family (Turdidae), but is now considered to be an Old World flycatcher (Muscicapidae). Around 12.5–14.0 cm (5.0–5.5 in) in length, the male and female are similar in colouration, with an orange breast and face lined with grey, brown upperparts and a whitish belly. It is found across Europe, east to Western Siberia and south to North Africa; it is sedentary in most of its range except the far north.

The term Robin is also applied to some birds in other families with red or orange breasts. These include the American Robin (Turdus migratorius), which is a thrush, and the Australian red robins of the genus Petroica, members of a family whose relationships are unclear.

O pisco-de-peito-ruivo (Erithacus rubecula) é uma pequena ave que se conhece bem pela mancha alaranjada que lhe ornamenta o peito. É uma ave de canto melodioso e persistente.

É uma ave pequena, com cerca de 14 cm. Os adultos apresentam o peito e a testa de cor laranja ferrugínea muito característica. Os juvenis são castanhos com pintas abundantes castanho amarelado e mudam para a plumagem de adulto ao fim de um ano. A alimentação é feita à base de: Insectos, aranhas, minhocas e caracóis.

The Egyptian Goose (Alopochen aegyptiacus) is a member of the duck, goose and swan family Anatidae. It is in the shelduck subfamily Tadorninae, and is the only extant member of the genus Alopochen. mtDNA cytochrome b sequence data suggest that the relationships of Alopochen to Tadorna need further investigation (Sraml et al. 1996).

O ganso-do-egipto (Alopochen aegyptiacus) é uma ave anseriformes do grupo dos gansos. É também conhecido por ganso-do-nilo, ganso-raposo e em Angola por balandira. A sua área de distribuição inclui Europa e África. É especialmente comum a sul do Saara e vale do Nilo.

Garça-real – Parque da Cidade

The Grey Heron (Ardea cinerea), is a wading bird of the heron family Ardeidae, native throughout temperate Europe and Asia and also parts of Africa. It is resident in the milder south and west, but many birds retreat in winter from the ice in colder regions. It has become common in summer even inside the Arctic circle along the Norwegian coast.

A garça-real-europeia (no Brasil) (Ardea cinerea) é uma garça da Europa cuja aparência é a de uma ave com dorso cinza e faixa superciliar negra que se estende até as longas penas nucais. Também é conhecida pelos nomes de galangundo (em Angola), garça-real ou garça-cinzenta (em Portugal).

Da mesma família das cegonhas, é a garça mais abundante e difundida da Europa. Possui um comprimento de cerca de 95 cm, uma envergadura de 185 cm e peso de 1,6 a 2 kg. Pode viver cerca de 25 anos. Apresenta pernas altas, pescoço longo e bico longo e afilado. Os juvenis apresentam cores mais claras, dorso cinzento acastanhado e ventre branco raiado de negro. Não possuem penacho. Atingem a maturidade aos dois anos de idade.
