Do birds have a favorite color? It's probably not a question you've ever 1 but a project designed to answer that question led to two British schoolboys 2 the Young Scientist Award of the year after presenting their 3 to a group of judges.
The boys' 4 to find out whether birds have a(n) 5 for a particular color came purely from scientific curiosity. Both of them are very 6 about nature and the power of colors in things, 7 they worked as a perfect combination and 8 a citizen science project that didn't require fancy equipment.
The boys 9 bird feeders in their back gardens. Each garden had five feeders, colored blue, green, red, yellow and transparent. They made sure to change the position of the feeders regularly, 10 it affected the results and then placed a 11 for an hour each morning, afternoon and evening across all four seasons to 12 birds visiting each feeder. They collected 13 covering a total period of 400 hours.
When the experiment finished, they had recorded the birds' 14 to the gardens added up to 3,205, with over a third being to the 15 feeders. It was a conclusive win for blue. The pair believe that blue is 16 to birds because of its familiarity, while red and yellow are often 17 of poison in nature.
Later, the boys considered 18 for their findings, such as using the less popular colors of red and yellow to 19 bird strikes on planes. There seems to be quite a strong connection between the 20 of planes and the number of bird strikes.
