The Hummingbird Citizen Science Project! 1.Question – How does forest cover influence hummingbird presence and abundance? 2.Hypothesis – There will be more hummingbirds in areas with more forest cover 3.Methods – Research by citizen scientists like you! 4.Experiment – Record the amount of nectar in your feeder and observe the hummingbirds you see around the feeder for 2 months 5.Results – The data from your observations! 6.Conclusion – Do your observations support our hypothesis?
