New media such as internet-connected cameras in nestboxes can yield infra-red images in the dark leading to new insights and knowledge. Substantial new information has become available from the groundbreaking webcam project of Vogelbescherming Nederland Beleef de Lente that started in 2007 and continues to this day. Volunteers select video clips revealing as yet undiscovered remarkable behavior over 14 entire breeding seasons, day and night, from courtship to egg-laying, to the fledging of the young. Due to simpler and cheaper technology, more and more people have decided to install such cameras in their nestboxed which is expected to yield even more new knowledge in the future, opening unprecedented opportunities for citizen science. This chapter is complemented by a lot of information from the long-term research of Van Harxen and Stroeken (from 1986) in their study area in Southeast Achterhoek in the Netherlands.
