In my opinion the sence of smell is much common in birds much more than people think! Researchers in Israel found that the mostly nocturnal Eurasian stone-curlew find it way by smell!Oh my! I wonder what one of those would taste like? When I was a kid, I used to lay out in the back and try to lure the turkey vultures to my carcass.They would swoop in really low for the initial inspection, I could hear their flight feathers rattling, but would never land. Guess I didn't smell bad enough! Fun bird fact: they are one on the few birds that have a sense of smell.
