Indeed, I completely agree that some birds are very intelligent, managing to pack quite a lot of punch in such a small package. Parrots, corvids, even pigeons are examples of such intelligent birds. This is why I was careful to select Chickens as the example that I did. Near the 48th second of this video: https://www.youtube.com/watch?v=exsrX6qsKkA https://www.youtube.com/watch?v=exsrX6qsKkA, you can see the bumble bee actually hesitating to work out which option will yield a reward for the least amount of effort. That kind of laziness is an excellent display of flexibility and intelligence. It's also interesting that you mention colony collapse. If as is likely, neonicotinoids play a significant role in colony collapse then the bee's sensitivity to disruptions in acetlycholine pathways is an argument for their relying heavily on cognition for foraging and navigation. But yeah, I'm not saying bees are just as intelligent as primates, corvids or parrots; just that they too are capable of quite unique sophisticated behaviors and learning.
