Description
As a consequence of climate change, many migrant birds have to advance the arrival at their breeding grounds in order to keep in synchrony with local food peaks. Some species manage to do this, whereas others fail to adjust sufficiently. Basically four different processes exist by which migrants can change their annual cycle to maintain the synchrony: 1. Advancing departure from wintering grounds, 2.Increasing migration speed, 3. Wintering at more northern latitudes, 4. Dispersing to more northern breeding sites with later phenology. In this talk I review some of the evidence for all four of these strategies, and discuss why some species may adjust, whereas other fail.
