Most attractive fruit colours to birds

Solitary black mulberry on a tree

There was only one mulberry on the mulberry tree last summer, lucky it was blackā€¦

Reading about the Kordia sweet black cherry, I remembered my notes saying black was the least favourite fruit colour of birds

In descending order of attractiveness:

  1. Purple
  2. Red
  3. Orange
  4. Black (mulberries)
