Spring songbird migration changes
The songbird sounds of spring may start to arrive earlier in Canada as our climate continues to change. In their study, Changes in wind assistance for nocturnally migrating bird populations, Cornell Lab ornithology scientists in the US, have projected that climate change may cause stronger winds during some bird’s nocturnal migration period. Using data from weather radar and extracting wind data from 28 climate-change projections in the most recent report from the Intergovernmental Panel on Climate Change, the researchers predict winds from the south will become stronger by the end of the century during spring and fall migration periods.
