Plain canary is an ingredient of many mixes for cage and aviary birds
The name 'canary' does not indicates that it is for canaries, but rather that it originates in the Canary Isles
It is also known as 'Moroccan seed' for similar geographic reasons
In fact, it is predominantly fed to small birds like budgerigars, parakeets and cockatiels, most often in an aviary setting.
Johnston and Jeff seed mixes are cleaned to a very high standard right through from entry process to the bagging off point.
These processes begin by getting rid of large impurities, stage 1 deals with polishing the seeds which breaks up any poor quality seed that then gets removed.So you can be assured of a clean dust free mix containing good quality ingredients.
