How is his claim holding up, or is he promising too much? Since it's the last news of the thing for captive crows were from 2012 and there is also [thecrowbox] and a correction of the correction [2]. There is still no working version for wild crows[3]. I just still don't know what to make of this since I can hardly see bad intentions other than being a bit overly enthusiastic about the whole thing while producing somewhat underwhelming results in practice. If it would have been some sort of hoax or stunt he probably would have said something by now, like it was an art project or some media hack or anything else along those lines.

on HN thread Some birds use discarded cigarettes to fumigate their nests
I think some birds are actually pretty smart and can learn by imitating other birds, so it's a cultural thing. All it takes is one bird to discover it. Take a look at this video: "Crow uses a vending machine". It was an experiment where they trained crows to collect coins and put them into a vending machine for a few grains. [this video]
Crows trained to trade coins for grain.
