Amazing the Red Lories look great amongst the rainbows, same with that yellow bibbed on the fourth tray from the right. Are there any problems with inbreeding. I mean there are lotsa Trichoglossus S.Species and i can see 2 from that phot and both of them breed with Musks. Wish i could send you some Purple Crowns for there to..
yeah, there have been some instances of the different trichoglossus subspecies interbreeding, but its not a serious problem, they largely stick to their own s.species.
Good eyes! There are Yellow-bibbed Lories in there. If memory serves me right, these are the species in the aviary:
Rainbow Lorikeet (several s.species including red-collared and Indonesian)
Musk Lorikeet
Scaly-breasted Lorikeet
Red Lory
Violet-necked Lory
Blue-streaked Lory
Ornate Lory
Black-capped Lory
Chattering Lory
Yellow-bibbed Lory
Purple-naped Lory
Dusky Lory
In addition, there are a pair of Palm Cockatoos and a pair of Pesquet's Parrots in there as well.
The pesquets are a recent addition. Previously galahs, major mitchell's and red-tailed black cockatoos were housed there, but they've been removed for some reason.
Visitors walkways are all elevated. Ground level access is for staff only. The bridge and tower are about 6 to 10m high (varies because the aviary is built onto a steep slope).
I guess there may have been isolated incidents of theft, but nothing major have been reported to my knowledge. The walk-thru areas all have security features like CCTVs and motion sensors to deter thieves. Even parrots in caged aviaries are protected by motion sensors.
A bigger problem is probably escape. I'm pretty sure several rainbow lorikeets have escaped from the exhibit. A couple of African starlings and wood hoopoes which escaped from the Waterfall Aviary can often be spotted within the park grounds.
