A quote:
The avian eye is large relative to the size of the head & brain. For example, human eyes make up about 1% of the total mass of the head; European Starlings eyes make up about 15% of the mass of their head. The advantage: large eyes provide larger & sharper images. Birds also have 3 eyelids; one upper and one lower eyelid plus a nictitating membrane. This nictitating membrane is between the other two eyelids and the cornea and has its own lubricating duct equivalent to our tear duct.

Wow, that is a really strange question. I don't believe they actually cry, but yes, they do have tear ducts. Eyes from every species need moisture.

I think maybe you have been listening to too many Prince songs...."When Doves Cry".

I've heard of tear ducks.
Doves sound like this when they cry:
"Coo-hooo"
