@Ituri Do you know how many there are in Calgary, as well if they are actually hybrids with domestic pigs? Is this the only Canadian facility with them?
When I spent 3 days at Calgary Zoo in 2012, there weren't any Eurasian Wild Boars anywhere, and instead the zoo had Collared Peccaries in this exhibit. During my most recent visit to the zoo (August 15th), I saw two Eurasian Wild Boars in the Asian loop, one Red River Hog in the African zone and 4 or 5 Chacoan Peccaries in the small South American section.
@wild boar no idea. To add to @snowleopard 's comment, there were wild boars there in 2008. So they are likely different animals than I saw back then. I have no idea where they came from.
