European jackal
The European jackal is the largest of the golden jackals, with animals of both sexes measuring 120–125 cm (47–49 in) in total length and 10–13 kg (20–29 lb) in body weight. One adult male in North-Eastern Italy is recorded to have reached 14.9 kg (33 lb). The fur is coarse, and is generally brightly coloured with blackish tones on the back. The thighs, upper legs, ears and forehead are bright reddish chestnut. Jackals in Northern Dalmatia have broader than average skulls, which is thought to result from human induced isolation from other populations, thus resulting in a new morphotype.
Golden-headed quetzal
The golden-headed quetzal weighs between 154-182g. It has a wingspan of 30–36 cm and a length of 33–36 cm with tail plumes adding another 8–10 cm. Like other members of the genus "Pharomachrus", the golden-headed quetzal is known for its iridescent golden-green wings and breast, which can appear blue depending on the light. The female’s breast is a duller brownish colour; her head is also a duller golden-brown when compared to the male’s gold-bronze head, from which the species name is derived. Their bills are short and broad; they appear yellow in males and a brownish greyish in females. The quetzal’s uppertail coverts are darker green and extend beyond the tip of the tail, more so in the male than in the female. Both the male and the female have a black undertail, though the female sometimes displays greyish-black tips. The feathers on the lower breast of both sexes are a brilliant red colour. Both sexes, like other trogons, also have heterodactyl feet, with the first and second toes facing backwards and the third and fourth toes facing forward. Their legs and feet are an olive green or a brownish colour. The young golden-headed quetzal is a brownish black colour with a few iridescent green feathers on the neck and breast, and lacking the tail coverts of the adult. The golden-headed male quetzal differs from other quetzals in its lack of a crest of head feathers.
