The first major section of the zoo is 'America'. This section starts with a wooded path, along which you find glass fronted exhibits for Toco Toucan, Squirrel Monkeys, Pygmy Marmoset, Golden-Headed Lion Tamarin and Patagonian Mara, along with a fair number of your standard 'show' macaws, mainly Blue-and-yellow. These are all of a decent standard, if a little smaller than I'd have liked for the birds and Mara. This path ends up at a courtyard of some sort which was, at the time, closed but looked like either shops or some sort of petting zoo.
The next major exhibit in the 'America' section is a very large walk-through aviary, with the entrance themed as a temple. On the way in you can pay 1€ for a bag of bird seed which isn't really worth it as the vast majority of the birds in the aviary give it a wide berth. The aviary is well-stocked with a variety of bird species from the Crested Screamers and Chachalaca on the forest floor and Whistling ducks in the ponds right up to the parrots occupying the canopy. I didn't take a full list (for my heart lies with the mammals), but it contains pretty much all of the South American birds listed on Zootierliste for the park (it can be found on the Zooindex as 'Benidorm').
You exit the aviary via an impressive moated outdoor exhibit for Guianan Brown Capuchins, with Capybara on the banks. Whilst it is difficult to remember the exact location of each exhibit (I am writing this a week after the visit, and the zoo was something of a maze anyway), but I believe that roughly opposite the Capuchins was an exhibit for Ocelot, the first of many woeful carnivore exhibits in the zoo. The space was very restrictive, the water bowl was empty and dirty, and the one visible cat was pacing compulsively, in what was apparently an act of boredom and associated stress as opposed to the 'patrolling' of a territorial boundary that stereotypical behaviour can easily be conflated with.
The remaining exhibits in the American section were a mixed-bag: another couple of good primate exhibits for Goeldi's Marmoset, Emperor Tamarin, a fairly standard exhibit for Oriental Small-Clawed Otter and a basic but adequate pen for Collared Peccary. On the other hand, Chilean Flamingo were kept in a basic pond that was uninspiring but that just about did the job for a small flock. A single melanistic jaguar was also held in a dreadful exhibit which had very little to offer at all.
Also in 'America' is a domestic livestock walk-through, which is great fun if you like tip-toeing about to avoid the goat droppings. There was also a single llama in a holding pen, and another exhibit beside the walk through for Rhea. The fence of this exhibit would allow guests to touch and probably feed the birds, which, if a boisterous child or indeed adult were to mess about could pose a fairly significant health and safety hazard.
