there is a lot of similar behavior between various species of animals. as i’ve recently read about bears (both here in the BPL Forums and on some links to authoritative web articles), i see so much similarity between certains aspects of bear behavior and dog behavior (which i am rather familiar with). yes, there still are diffs., but a lot of similarities.
i’m guessing that, like dogs, bears will investigate a “new” scent, e.g. cardamom, out of curiosity just for a closer sniff and possibly taste to see if it’s edible. bears, being omnivores, might even be more curious about these non-meat scents than carnivorous dogs are (and dogs are still curious about them). they also have a much better sense of smell than even blood-hounds (3x the nasal passage surface area with olfactory related nerve endings, and a larger pct of their brain devoted to olfactory than dogs).
to me, cardamom smells like it could be food. imagine how a bear might perceive it!
however, i know nearly nothing about bears, so i’m just guessing here. better to err on the side of safety. remember, if a bear finds out, upon closer investigation, that it doesn’t like the cardamom, there is always the nearby human!!! that’s why i also hang the food far away from the night’s bivy area and hope that i can remember where and find it the next morning! [prob. naive – if a dog could track me from the “hang” to the bivy, a bear certainly can too – but, still a good thing to do.]
