= __Introduction__: i was wondering how birds react to other birds, so i got a place where birds often come to (or not so often) the bird feeder. i couldn't have real birds by the feeder so i had bird calls, and i played them for an hour each day and measured how much bird seed was gone at the end of the week. =

=** __Question__: Will the bird feeder with cardinal, robin, and chickadee calls coming from it attract more birds than the bird feeder with out bird calls coming from it? **=

= **__Hypothesis:__ I think that the bird feeder with bird calls coming from it will attract more birds, but it will attract mostly, cardinals, robins, and chickadees because they will hear there fellow species mating calls and come, because they like to mate.** = = = = **__Procedure__: I will have two identical bird feeders filled with the same bird seed. I will measure how much bird seed is in there then I will put them outside. I will put a speaker near one of the bird feeders for an hour each day playing cardinal, chickadee, and robin calls. Each day I will measure how much bird seed is gone, and after a week see how much bird seed is gone.** =

= __**variables**__ = =** independent variable: feeder with calls vs. feeder without calls **= =** dependent variable: how many birds come to each feeder. **=

= __**results:**__ **the feeder with the bird calls was not eaten at all. the feeder without the bird calls was not eaten at all either. out of all the feeders no birdseed was eaten.** =

= **__Discussion:__ With both bird feeders, no birds came. I don't know if this is because they just never found the feeder, or if they didn't like the birdseed or maybe the weather wasn't good enough. So in the end my experiment didn't work, it didn't matter if there were bird calls playing or not. So my hypothesis wasn't proven wrong.** = = = =__ **Future:** __ **if i were to to do this again sometime in the future, i would use a real bird feeder, and leave it out longer so that the** **birds get used to it.** =
