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

Ganso do Egipto – Parque da Cidade

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.

Yellow-bellied slider turtle (tartaruga-de-orelha-amarela)

Scientific name: Trachemis scripta scripta

Parque da Cidade (Oporto – Portugal)

Tartaruga – Parque da Cidade

The yellow-bellied slider (Trachemys scripta scripta) is a land and water turtle belonging to the family Emydidae. This subspecies of Trachemys scripta is native to the southeastern United States, specifically from Florida to southeastern Virginia, and is the most common turtle species in its range. It is found in a wide variety of habitats, including slow-moving rivers, floodplain swamps, marshes, seasonal wetlands, and permanent ponds. Yellow-bellied sliders are popular as pets.

 A Tartaruga de orelhas amarelas ou Trachemys scripta scripta habita as regiões da Virginia, Carolina do Norte, Florida, Carolina do Sul e Georgia, apresentando a carapaça de coloração negra, com listras marrons verticais.

O plastrão é amarelo, sem mancha ou apresentando poucas de cor bem escura. A cabeça é bem escura apresentando manchas de cor amarela e ela atinge menor porte que as orelhas vermelhas, cerca de 25 centímetros de comprimento de carapaça. Essa subespécie possuí a carapaça e a cabeça mais parecidas com as Tigres dágua brasileiras, porém o plastrão torna fácil essa diferenciação.
