In principle, field guides make bird identification easier. In reality, some of their distinctions require ideal light, infinite patience, or a more cooperative bird. The following ten fall into that category.
“Shows a slightly finer bill profile.”
“Marginally paler fringes to the tertials.”
“Typically a touch more contrast on the facial pattern.”
“Often fractionally shorter-tailed.”
“Tail corners fractionally more prominent in flight.”
“Underparts generally marginally cleaner.”
“Wing panel usually a shade less prominent.”
“Slightly crisper edging on the greater coverts.”
“Subtle difference in the intensity of the eye-ring.”
“Supercilium a trace broader.”
Good luck spotting these differences in the field …
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.
