Is tax free dividend income received in india taxable in the usa?

i am a non-immigrant visa holder from india living in the usa. i am not a green card holder. i am a non resident indian. the only income i receive in india is a small amount of dividends from shares purchased by my father in my name. the amount is less than $500 per year. in india, dividend income is tax free. india and usa have a tax treaty. do i need to declare this income in my usa tax return?
