Subspecies – which self-respecting birder doesn’t secretly dislike them? And yet, some bird species seem determined to accumulate as many of them as possible. The table below shows the worst offenders.

Of course, each of these species would claim to have a perfectly good excuse. Most point to their enormous geographical range, their occurrence on numerous isolated islands, or the existence of many isolated mountain populations. Convenient excuses, but not necessarily convincing ones.

Kai has lived in Shanghai for 22 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.
