Should we feed our birds rape seed?
Is it dangerous?

Rapeseed (canola) is a common ingredient in seed mixes. I don't know of any reason it would be dangerous. Why do you ask?

I read this on the finch info web site
http://www.finchinfo.com/health.htm
"Acorns, lettuce, carrots, rape seed, grape seeds, bananas, spinach, onions, milo, grapes, and raisins have high levels of tannins. (Rhubarb, tea, coffee, and chocolate also contain high levels of tannins but these foods should never be fed to birds anyway as they may be harmful or toxic). Tannins can inhibit digestive enzymes, bind protein, and reduce the bioavailability of vitamin B12 and iron.5 Additionally, at high levels, tannins can cause epithelium and liver damage.5 Tannins (tannic acids) are the chemicals that are responsible for the normal browning of fruits and vegetables that have been bruised or cut. If feeding any of the above-listed "safe" foods that contain tannic acid, only feed them in moderation. "

All I know is... the two Herman Bros. seed mixes my birds have been eating for many years both contain rape seed. And as far as I can tell they are doing fine.

Of course, my little guys won't actually eat the rape seed! (I also get a mix from Herman Bros.) I think it's one of those foods that should be fed in moderation. I know that spinach (also on your list) isn't healthy if fed in large quantities, but is great if you just feed it upon occasion.

That was listed in one of the avian medical texts I reference, and I'm fairly certain it refers to *large quantities* (i.e. if you fed a diet that was mostly or completely made of rapeseed).

Thanks!
I was wondering about that.
I noticed rape is a large component of canary seed mixes.

if you read strouds book on canaries.you will find that he recomends 3 different types of rapeseed,and i dont think he would have let you feed your birds anything harmful to them.i have been feeding it to my canarys for years,granted a lot of them dont eat it but if you try soaking and sprouting it you would certainly see a difference in the amount they consume

Ah ha! Maybe THAT's what I can do with all of the leftovers! Even my canary doesn't like it......

hi hilary
have you tried the seed yourself as it maybe old and thats why the birds will not eat it,if you put a piece in your mouth it should have a nutty flavour but if it tastes bitter then it is no good and you are being sold inferior seed that normally gets crushed for its oil content.....is you seed merchant reliable is there any webs or white dust on the seed or is it clean and polished.you could try buying it seperate and mixing it your self rubsen rape seed is best then morrocan you can even get red rape seed ..but if they are not even taking a few of the seeds it may be inferior stock.....buy the way you can try any seed the same way if you can plunge your hand in the seed and there is no resistance the chances are that it is good seed but if there is resistance and dust flys up and your hand gets covered in webs then it is inferior
