The death of a man whose near-naked body was found in a Queens bird sanctuary over the weekend has been ruled a homicide, cops said Tuesday.

A passerby discovered the corpse — clad in only underwear and socks — in Bayswater Point State Park in Far Rockaway shortly before noon Sunday, cops said.

The unidentified man had suffered trauma to his head and body, officials said.

His death remains under investigation, and no arrests have been made.
