I went to Perth Zoo today, must be up there with the most marsupials you can see in any collection. Unfortunately a few species have gone from the nocturnal house:
1) Goodfellow's Tree Kangaroo Dendrolagus goodfellowi buergersi
2) Red-tailed Phascogale Phascogale calura
3) Dibbler Parantechinus apicalis
4) Western Ringtail Possum Pseudocheirus occidentalis
5) Bilby Macrotis lagotis
6) Sugar Glider Petaurus breviceps ariel
7) Northern Quoll Dasyurus hallucatus
8) Western Quoll Dasyurus geoffroii
9) Feather-tailed Glider Acrobates pygmaeus
10) Long-nosed Potoroo Potorous tridactylus
11) Short-beaked Echidna Tachyglossus aculeatus
12) Red Kangaroo Osphranter rufus
13) Western Grey Kangaroo Macropus fuliginosus
14) Tammar Wallaby Macropus eugenii
15) Western Brush Wallaby Macropus irma
16) Koala Phasolarctos cinereus
17) Tasmanian Devil Sarcophilus harrisi
18) Quokka Setonix brachyurus
19) Numbat Myrmecobius fasciatus
20) Southern Hairy-nosed Wombat Lasiorhinus latifrons
Also, just out of interest, about a week before the new year I went to Caversham Wildlife Park. If I'd known it would be a marsupial challenge I may have done that afterwards. That would have added a further 13 species to my list, which for fun are:
Benett's Wallaby,
Swamp Wallaby,
Red-necked Pademelon,
Squirrel Glider,
Agile Wallaby,
Wallaroo,
Spotted-tailed Quoll,
Common Brushtail Possum,
Rufous Bettong,
Brushtail Bettong,
Northern Nailtail Wallaby,
Common Wombat,
Southern Brown Bandicoot
So 33 species possible in the two main Perth collections is certainly a good total! (and in fact if you were to go to Peel Zoo south of Perth you could pick up the 4th Australian Quoll there too). I will probably be back in Perth in December so might go back to Caversham and pick those up then.
