You may wonder why on earth anyone might ask this question, or how to answer it. Here is the story behind it.

Two researchers wanted to know how human behavior toward birds affects them. So, they first asked people in Berlin and in Seattle if they liked birds – did they feed them or rather shushed them away (or even shot them)? The result: Residents of Berlin encouraged birds more than residents of Seattle did, while Seattleites discouraged birds more than Berliners (point for Germany, though I have been living elsewhere for so long now that I cannot say I contributed to this in any way).

So, that is the answer to the question above. But it was only the start of the research. The main work was to check flight initiation distances for different species in both cities – how close can you get to a bird before it flies away? Here, the strongly discouraging behavior of people in Seattle, particularly in rural areas, meant that the birds there flew away earlier. So, the birds were indeed affected by human behavior toward them.

Another finding was that these flight initiation distances are shorter in urban than in rural areas. So, next time you want to get a close-up of a rare bird, try to find it in the city center rather than in a field.

Kai has lived in Shanghai for 21 years. He only started birding after moving to China, so he is far more familiar with Chinese birds than the ones back in his native Germany. As a birder, he considers himself strictly average and tries to make up for it with photography, which he shares on a separate website. Alas, most of the photos are pretty average as well.He hopes that few clients of his consulting firm—focused on China’s chemical industry—ever find this blog, as it might raise questions about his professional priorities. Much of his time is spent either editing posts for 10,000 Birds or cleaning the litter boxes of his numerous indoor cats. He occasionally considers writing a piece comparing the two activities.
