Yup, that’s a drone hovering over the construction site for the 56-story, $630 million Millennium Tower project at the old Filene’s site (captured by editorial director David Harris).

A spokesperson for Suffolk Construction, which is the project manager for the site, says the mini-helicopter isn’t theirs and referred calls to project developer Millennium Partners.

Joseph Larkin, a principal at Millennium Partners, said that the firm is using the drone to capture “the views that will be enjoyed from different residential units once Millennium Tower is complete.”
