Apart from the pictures already shown by
@snowleopard there is another significant bird complex in Artis, the pheasantry and the adjacent Masman house (a former summer house predating the zoo and housing birds sinds 1863). This area is (like most structures in the zoo) a monument and was renovated some 10 years ago:
@twilighter - The inner lane has lower aviaries with mostly smaller tropical species.
@vogelcommando - The outer aviaries on either size are of greater height and house groups of blue-throated macaws (pictured here) and scarlet + puna ibis on the other side
It is hard to find a proper picture of the Masman house with aviaries for ground hornbill (the only one I find too small for its inhabitants) and ocellated turkey among others:
@vogelcommando
The former primate house is now mainly a walkthrough, but also has some birds in there like guira cuckoo & burrowing owl:
@vogelcommando
The outdoor enclosures now hold galliforms, with Himalayan monal & satyr tragopan on the outside aviaries
@vogelcommando
and Red-billed curassow in the centre, which is more a greenhouse than an aviary:
@vogelcommando
The other area were birds are concentrated is the Metzelaarskas which houses a variety of Asian species like crowned pigeon, collared kingfisher, red junglefowl and more. This tropical greenhouse isn't really represented by a proper picture, but this is the best around:

Apart from that there are ratites in standard enclosures, African penguin & northern gannet in a large enclosure with a too shallow pool and Caribbean flamingo in an open-topped exhibit. But by and large most birds in Artis live in beautifully restaurated monumental buildings which are well-planted and thoughtfully designed in general.
Whereas Paris has some nice exhibits, especially the larger flight cages and a fun old-fashioned pheasantry in the Jardin des Plantes. There are a few things I dislike, that includes the numerous pinioned birds in with hoofstock and the small and boring bird-of-prey, parrot and owl aviaries in the Jardin des Plantes. Compared to the fresh-looking displays in Artis, they look very tired.

So quantity is for Paris, but quality is consistently higher in Artis in my opinion.
