Birds living in urban habitats recognise individual human faces. Urban bird species discriminate and remember humans based on their previous experiences with them.

How long can a bird remember you?

Some research on ravens, however, suggest they can remember the calls of various individuals for at least three years (Boeckle & Bugnyar, 2012); pigeons have been tested foronly up to about six months on memory for objects (Cook et al., 2005)—but no one knows how long their memories might really last.

Can birds remember human faces?

Ravens and other members of the corvid family (crows, jays, and magpies) are known to be intelligent. They can remember individual human faces, expertly navigate human environments (like trash cans), and they even hold funerals for their dead.
