It has been shown that climate change has significant impacts on the phenology of organisms including bird migration. Scientists have found that the spring is arriving early and many species are responding by migrating early. We focused on the potential effects of climate change on the first arrival dates of migrating ruby-throated hummingbirds. We collected data on the first arrival dates and average monthly temperature for five states (Florida, South Carolina, Virginia, New Jersey, Maine) and analyzed for correlations. We found that the spring temperatures are increasing over the last decade in some areas (i.e. advancing spring) and hummingbirds are responding by arriving early.
