=__Bird Investigation__= = = =__My Question:__=

Will birds eat more food with loud noises or quiet noises? = = =__Background Information:__=

Loud noises, even ones birds know, like rushing rivers and waterfalls, will make birds nervous and they will most likely fly away from whatever is causing the noise. Birds also do not appreciate human music, although some soft music may attract birds, most music will have the opposite effect on birds =__Hypothesis:__=

My hypothesis is that birds will eat more food when there is quieter noise. Loud noises will most likely scare them away. =__Variable:__=

Independent: If loud noises or quiet noises are being played Dependent: How much seed is being eaten =__Experiment:__=

For my experiment I will set up one bird feeder on a tree in my front yard and mark how full the feeder is. Everyday once I get home from school I will start to play loud music for 15 minutes and see how many birds visit my feeder and how much food gets eaten during that period of time. Then I will stop the music and for another 15 minute time period I will chart how many birds visit the feeder and how much food gets eaten. =__Materials:__=

 * Week#1 || ===Loud Noises=== ||
 * Day1 || 3 birds were at my feeder before I started to play disruptive music. When the music started the birds scattered, but after about 7 minutes, 2 birds came back but only stayed at the feeder for about 10 seconds. In the 15 minute time period, 9 birds visited my feeder The feeder was full when I started and after the 15 minutes the food had lowered about 2 centimeters. ||
 * Day2 || Before I started to play the music, no birds were at my feeder. 3 minutes into playing the music, 1 bird came to my feeder. Then 11 minutes in, 1 more bird came. In total 2 birds came to my feeder. But the food didn't lower. ||
 * Day3 || There were no birds at the feeder before I started to play the music. During the 15 minute time period no birds came to the feeder. ||
 * Day4 || Before I started 1 bird was at my feeder. When the music started the bird stayed at the feeder. After 3 minutes the bird left and another bird came. Within 10 minutes 3 more birds come and then no more after that. 5 birds in total came and the food went down by 1 centimeter. ||
 * Day5 || 2 birds were at my feeder. Once the music started one of the birds flew away. Within the 15 minute time period 6 birds visited my feeder. In total 8 birds visited my feeder. The food decreased by 2 1/2 centimeters. ||
 * Day6 || No birds were at my feeder when I started. During the 15 minutes 6 birds visited my feeder. The food went down by 1 centimeter. ||
 * Day7 || 1 bird was at my feeder. When I started the bird didn't fly away. It was the only bird at my feeder during the 15 minutes. The food didn't decreased ||

== __ **Conclusion:** __ = = My data shows that yes, birds eat more food with no music. For most birds, the loud music scared them away. Although a few birds came to eat while the music was being played, most birds enjoyed the peace and quiet while they ate. = = =__Bibliography:__= "Sounds That Attract Birds." //About.com Birding / Wild Birds//.

 * Week#2 || ===Quiet Noises=== ||
 * Day1 || 4 birds were at my feeder. With no music playing, 6 minutes in, 7 birds visited my feeder. In total 11 birds came and the food went down by 3 and 1/4 centimeters ||
 * Day2 || The first 2 minutes no birds came to my feeder. 5 minutes passed and still no birds. Then 10 minutes in 4 birds came and in the last 2 minutes 1 bird came. In total 5 birds came but the food only went down by 1 centimeter. ||
 * Day3 || 8 minutes in 6 birds had already visited my feeder.Once the 15 minutes was up a total of 12 birds visited my feeder and the food decreased by 4 centimeters. ||
 * Day4 || Within 2 minutes 3 birds had visited my feeder. By the end of the time period 7 birds visited my feeder and the food went down by 1 1/2 centimeters. ||
 * Day5 || Throughout the 15 minutes 10 birds visited my feeder and the bird seed decreased by 2 centimeters ||
 * Day6 || 6 minutes in 4 birds had visited my feeder. After the 15 minutes 8 birds had visited. The bird seed decreased by 1 1/3 centimeters. ||
 * Day7 || In the first 2 minutes 4 birds visited my feeder. Then at 7 minutes 6 birds had visited my feeder. At the end of the 15 minutes 12 birds visited my feeder and the food decreased by 2 1/4 centimeters ||
