@Zoofan15 So we could be looking at a shortfall of tiger numbers within the near future!
Yeah, what we have is best described as an aging population and if the inevitable wave of age related deaths are compounded by a few unexpected deaths amongst the younger cohorts, there could easily be a shortfall. That said, they’re not hard to breed and this easily can be addressed. Even in the face of a shortage, I’d prefer to see new imports combined with strategic pairings; than a glut of surplus tigers produced for no other reason than to stock up the zoos.
Nice graph and cheers for info about '92 beginning to regional breeding program and wow Frank and Poetry were elderly parents for Tigers but I know so were Meta and Nico still having later cubs like Jambi etc quite old too. Interesting about Quintus and TZ's desire to describe him officially as a Sumatran Tiger when he had a mixed subspecies origin. Tetrapod told me back in late 2016 that a lot of zoos back in the day had Tigers signed as being Bengal when they were sometimes of mixed origins. I think Perth Zoo just displayed their mixed origin Tigers as 'Tiger pantherus tigris' right up to '92 when Calang arrived from MZ (as far as my memory goes back which is about '92 I've only seen Tigers displayed at zoos under their subspecies including the last Bengals at Mogo Zoo in early 2000s and last Bengals at Western Plain in mid-late 90s just before Seletan and Shiva's cubs went there, but until Tetrapod told me about Calangs arrival year I wrongly assumed Perth Zoo was already keeping Sumatrans back in the 1980s).
You’re welcome and cheers. Given Poetry was a first time breeder at the age of 12 (and had likely been on contraception prior), it’s especially lucky she was able to breed. Her first litter (a single cub) was stillborn in July 1990; followed by the twins in November 1990 (Calang and Selatan).
Calang was transferred to Perth Zoo in 1994; with his mate, Malu, imported in 1999. To my knowledge, they were the first Sumatran tigers at Perth Zoo.
That’s correct re. Bengal tigers. Imports via animal traders in the first half of the 20th century brought them straight from India; but anything claimed to be a Bengal in recent years is just a generic hybrid. The first tigers imported from the USA by Dreamworld had an air of Siberian about them by the look of the facial hair on the males - especially Mohan.
