Hi Shirley,

There is a nice simple answer here, and that is that blue, true blue, is a signal for poison in nature. Purple is often ok but there are no natural foods that are blue.

I think the idea for this project is great!

Regards,
Chris

Dear Shirley Cook,
I'm doing a project about birds vision,particularly their chose of colours .I conducted an experiment to see which colour bird seeds they will respond to.I found that most neutral ,red then yellow and green but the least preferred one was blue.When I tried to search why blue , i could not find enough info.If you know anything about the colour chose of birds could you please share with me.I also try to contact with Mr. Steven from UNE bird scientist,I was at bird watching once with him, if you know his contact details could you please write to me,he might help to explain why birds not like blue or they don't prefer.
Many thanks.
