#22Earlier quoted context omitted.
I remember reading an article in National Geographic of how crow's brains are much more interconnected than is the norm in mammals, i.e. IIRC they have a higher density of synapses between neurons. From that article, it seems that the usual brain weight vs. body weight to determine intelligence, which seems can be used to approximate intelligence in different species of mammals, cannot be used for birds (or at least…
I wonder what the energy/evolutionary cost of densely-connected brains is. If it's advantageous, why are crows exceptional?
It could simply be an evolutionary "discovery", with no particular advantage over our "brain model". Evolution doesn't seek out optima; it simply encourages genetic structures that improve odds of reproductive success.
Or, to put it another way: if corvid genetics happened upon a brain type that promoted their survival, it doesn't matter if it was "better" or "worse" than the path the monkey/hominid brains took. Genetics took the first bus going in that direction.

#24Wonderful timing. Me and my daughter just started to feed and befriend a crow in our backyard. We started by putting out a few pieces of cat foot, shaking the plastic container and tapping on the table we put it on to signal to the crow we had put out food. Within only 2 days the crow has learned to come and swoop down for his meal within just a minute or two after he does his normal fly-by passes. Now only about 5 d…
I'm hoping that is a typo for cat food, instead of training your cattle on horrifically scavenged body parts.

#25One of the craziest behaviors I have seen was from a murder of American crows in a big city area sidewalk I walk down frequently - occasionally, I have observed homeless and vagrants throwing stuff at them, because sometimes they sleep under the powerlines where the crows like to perch and I think the crows defecate on them or something. It's well known they can carry grudges, but one day, as I was walking down the s…

I'm not an expert in the area but have read a bunch on this topic to try and understand it better. Bird brains and human brains are structured very differently. Birds are much more like GPUs with independent distributed processing happening in parallel. Mammals have these big bidirectional layers where signals are constantly propagating up and down in a big connected computation.

Crows in country will wait for a newborn deer to be left alone in a field by their mothers shortly after birth to peck the baby's eyes out so it dies and the crow can eat it later. My neighbor had told me about this happening, and maybe a month later I saw a fawn with its eyes pecked out shortly after it had died. The doe just sat at the edge of the field by it all night. So sad, but really smart of the crows. Crows…
They also do this to lambs, they're smart but evil

Oh, crows are WAY smarter than that. If one tried to drop a stone on you, it was because it didn't like your online comments.

#30If you like the idea of smart corvids, Adrian Tchaikovsky's scifi novel "The Children of Memory" is a fun read.
