What Doesn’t Separate Us From Animals 6

Pigeons are watching you, and they don’t forget a face.

A new study shows that pigeons can distinguish between familiar and unfamiliar human faces, according

to Mat McDermott at Care2.com. The study was published in Avian Biology ResearchResearchers seemed surprised, apparently because they thought pigeons were fairly dumb (or, as they put it in scientist-speak, not “considered highly cognitive”). As usual, people tend to presume animals are stupid until proven intelligent.

This study comes on the heels of one finding that ravens can recognize the voices of friends and foes even after years of separation.

Consider pigeons’ memory and the likelihood that they have cognitive skills we have yet to acknowledge the next time you let your child chase and bully them into flying away: do you really want your kid on their bad side? (More to the point, do you really want your child to learn to abuse her or his power over weaker creatures?)

What Doesn’t Separate Us From Animals 5

A new study described in The New York Times found that ravens can recognize the voices of old friends after years of separation. Current Biology reports that a group of birds lived together for three years, then were separated for three years. Researchers recorded the calls of some of the separated birds towards the end of the three-year separation (during which time their calls may have changed) and played them to the other birds, who responded with friendly calls.

The birds’ friendly response demonstrated that they recognized their friends, because they responded differently to birds they didn’t like. Lead researcher Markus Böckle of the University of Vienna explained that when ravens answer calls from others they don’t like, they use deeper voices. The birds could also distinguish birds they did not know.

Ravens have friends and foes and remember them for years. Yet one more characteristic that does not distinguish humans from animals.

What Doesn’t Separate Us From Animals 4: Bees Have Personalities

Bees have  personalities and feelings, according to a new study. Their brains are similar to ours in several ways, including being affected by the same neurotransmitters.

The purported moral distinctions between humans and other sentient beings that are used to justify exploiting animals continue to lose credibility, while veganism’s abstention from the exploitation of insects by boycotting honey and silk is gaining moral ground. It is also getting easier to follow as substitutes for these products become more available. Healthier sweeteners like agave nectar and stevia are growing in popularity, and fabrics that look and feel like silk are not only on the market, they are cheaper than silk.
