There are many more factors than I imagined: compass errors, wind drift, overshooting, extreme weather and irruptions, natural dispersal, and human-driven vagrancy. Some birders may want to carefully read the chapter on human-driven vagrancy, which takes up the question of ship-assisted vagrancy. Next time, I’ll know why.

The trend in CII is positive and similar in the two regions. On both continents, interspecific and spatial variation in population abundance trends are well predicted by climate suitability trends. Two primary indices were derived, the Climate Suitability Trend Negative (CST-) and the Climate Suitability Trend Positive (CST+).

I visited Tengchong in late 2020 and wrote about it – but I also went there earlier, in 2017, and this post shows some photos I took during that trip, along with the usual comments that seem to be much more about ridiculing my fellow humans (especially ornithologists and the like) than providing useful information on birds.

It contains numerous citations to the literature, as the process must be based on the best available science.

Several national parks, national wildlife refuges, and state lands host significant populations.
