Fortunately, there are a few more such breeding species than most Shanghainese are aware of. While the HBW states that it breeds at 300 – 2450 meters, in Shanghai – where such elevations are not available outside of the upper floors of a few highrises – it makes to with an altitude of about 0 meters as well.

However, the authors call this a “new breeding tactic”, which seems to mix up the discovery of the tactic with the use of the tactic. In Shanghai, one way to find out was to measure the concentration of these chemicals in Eurasian Tree Sparrows from different locations.

And yes, sparrows in areas with polluted air are less healthy. For those males who pride themselves on being good karaoke singers, it may be pleasing to hear that among male Japanese Thrushes, males breeding with two females tended to have more various trills than monogamous male breeders ( source ).

There was a breeding pair at Binjiang Forest Park this June. What could be plainer than the Eurasian Tree Sparrow ? Most scientific research really just proves the obvious.

Given the complexity of the research, the result feels like a bit of a letdown – “northern populations start migration earlier than southern populations, especially in autumn” The species name of the Chestnut-eared Bunting is fucata , from the Latin “fucare”, to paint red. No wonder no species are named after me.

The bird “spent five months on Mindoro Island in the Philippines during the non-breeding season and migrated through Taiwan, the Chinese east coast, and the Korean peninsula” and on to the Russian Far East (indicating a certain lack of solidarity with Ukraine).
