New Experiments! Are seagulls colour blind?

Last week S2 checked out what colour of bread seagulls prefer.We dyed two of the breads different colours, one pink and the other blue, and put them in hoops outside where we could see them. We had a few students helping the set-up. Layla set the hoops in place, Matty was head photographer, then Lucas, Rata and Memory helped crumble the bread and put it into place.  In conclusion none of the seagulls trusted the blue bread. Most of the normal white bread was eaten, and all the pink bread was eaten. Only a few seagulls ate a little bit of the blue bread. But then one of the seagulls started to choke on the blue bread! I think that may have put them off eating the bread. In the end all the bread did get eaten. We are going to try different colours to see what happens.
The rain meant we couldn't repeat our experiment until Thursday. This time we chose different colours and positions. We used yellow and green this time as well as normal bread.The seagulls ate  the yellow and white bread really quickly and then moved onto the green. even though the green bread was closest.

I'm guessing the seagulls do not eat dark colours  because in the  last experiment they didn't eat the dark blue until last and went for the others really quickly.
