Native deciduous tree, variable shape in parkland. Miniature apple-like fruits with bitter taste. The Celtic "Tree of Love".
No interactions present.
Having returned home and looked into this a bit further it would appear that Malus sylvestris fruits are green / yellow and are sometimes flushed with red but it would seem never bright red all over like these ones. So I think lavateraguy's ID is safer, unless someone can come up with a species.

Chris, the fruit does look bright red from this angle and direction however the shaded side of the fruit did have yellow and green markings. A third photo of hand-held fruit would have shown this. Regards
