Imagine you have some special strong interest, such as observing birds. Would you expect scientists to be interested in your observations? Well, they may be! Many volunteers help scientists to perform important tasks as part of scientific projects. These volunteers are called citizen scientists. Over the past years, we have invited adults and students to participate in our research projects. In this article, we describe how citizen scientists contributed to our observations of bird behavior by collecting accurate data. We learned that good communication and detailed training sessions can help the volunteers to collect good quality, accurate data that can be used in the study and shared with the wider scientific community. We are confident that both the citizen scientists and the scientists profit from this collaboration and, most importantly, they all have fun doing it!
