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.
Great jacamar
It measures in length and weighs between . The adult male chin, cheeks and upper region are all bright metallic green with gold overtones, with a blueish tinge on the chin, forehead and tail and purple copper on the back. The lower part of the throat is white and the rest of the lower region is deep rufous. The primaries are black, the tail is blue-black, below the beak is black, and the legs are dark horn-colored. The female resembles the male, but has no white spot on the throat.
Like all members of the order Piciformes, jacamars and their relatives have zygodactyl feet, with two toes pointing forward and two facing back. Jacamars evolved with this toe arrangement, which helps them grasp branches while hunting in trees.
Because 13 of the 17 Galbulidae species belong to super-species complexes, researcher J. Haffer concludes that jacamars had a relatively recent Pleistocene radiation of the family. Jacamars are believed to have originated in the Amazon region where they are most common, and spread to other parts of Central and South America. Unique anatomical features of this family include a long appendix, no gall bladder, a bare preen gland, and a long, thin tongue.
