The old canary books speak highly of hempseed as an oilseed.
I have, on occasion, fed them locally-obtained seed (ask me no questions, I'll tell you no lies).
The canaries, goldies and weavers love it, the Aussie and African finches mostly leave it alone.

Technically those are hemp seeds. They are not the same as the marijuana plant that is high in THC. Merely in the same family as apples are in the same family as roses ...... It was commonly used in bird seed 'till somewhere in the 40's. Now it's not as easy to find.
That is total piffle.
There are two species of hemp,
Cannabis sativa and
C. indica, which have contributed to the strains grown in Australia, legally and illegally. Most are hybrids, selected for various desirable qualities. All of them are called hemp, cannabis, dope and many other things besides.
The differences in THC are much greater between the different parts of the plant than between the different cultivars; the flowering parts have much higher THC than the leaves and other parts. If the plant is allowed to go to seed, the THC content is much lower.
Thus, the plant can be grown differently to suit different needs.
For fibre, the seeds should be planted densely to make tall, leggy plants with a long, strong stem and minimal leaf and other parts. This approach will yield some seed as a byproduct.
For seed, the plants should be more widely spaced and allowed to develop a shrubby habit.
For the flowering parts, people grow as for seed, but try to weed out the male plants to avoid the females setting seed. This results in plants with big flowering heads but no seeds, which is desirable to the recreational smokers.
When the recreational smokers of my acquaintance get a bag of "seedy heads" they pick out the seeds for my canaries, hence my occasional supply. I laughed at the comment quoted above that it is hard to find these days. It is very easy to find if you are prepared to pay too much for illegal product. It is even quite easy to find legal supplies at more reasonable prices, like Nirep.
I don't see any advantage in using them for my birds over niger, linseed and canary. I have not noticed a calming effect, but I'm not sure that I would notice it if the was.
