Who is flying the longest distance: is it the arctic tern, the common cuckoo, or maybe the crane? Why do the birds fly from south to north in spring and back again in autumn? It is such a long journey!

This webinar is part four in a series of webinars about PHENOLOGY, which is the study of how plants and animals time their life events to the rhythms of the seasons. In the first part, I introduced you to phenology. In the second part, I told you about plants, and in the third part, I told you about insects. In this webinar, I will tell you about the phenology of birds, with emphasize on the species you and your pupils have observed in the EDU-ARCTIC Monitoring System. Later, I will follow up with webinars looking in detail at some of the Monitoring data. Please gather your pupils for these lectures, and let us explore your data for phenology patterns!
