When birds swallow neem seeds, can there be a contraceptive effect?

I heard that this was observed in Venezuela but find no info on the net. I've studied neem, mostly in South America, for 12 years, but in all the experience & studies available online have never found that mentioned.

It is said that birds don't suffer from exposure to the oil. When swallowing fruits, the seeds are normally excreted. The skin is bitter while the juicy fruit is sweet—I can only speculate that the skin may act like the oil as a contraceptive much as in human beings.

Do you know of any study or observation that sheds light on this? Soon I will peak personally with the person who communicated this observation, so may get more info.

Congratulations on a fine, balanced site. I may be able to contribute—I have many documents from here & there & some observations that could be of use. Cheers.

Birds eating neem seeds

Hello Dada Vimal/Victor,

Thank you for your kind words about my website.

I don't have an answer to your question, but I published it anyway because I find it interesting. Who knows, maybe one day a reader has an answer for both of us.

For me this is the first time I heard about it, or even thought about the effect of neem fruit on birds.
