A true dark chocolate will never have sugar listed first in the ingredients. It should always be below the cocoa ingredients. It should also tick as many of the following points:
Antbirds are mostly birds of humid lowland rainforests. Few species are found at higher elevations, with less than 10% of species having ranges above 2000 m (6500 ft) and almost none with ranges above 3000 m (10000 ft).
Everything is big to an ant. It cannot tell if there is a human standing there or an elephant or if it is just a tree gently swaying in the wind. So it is not going to run around panicking if it should see a human, otherwise ants will spend all day running around in fear and not get anything done.
