The obvious choice was the Mallard , that plucky familiar northern hemisphere species that is the father of the even more familiar domesticated duck. In fact, as the species was quickly identified as as creating hybrids with Grey Ducks, the opinion was by the 1920s that the species shouldn’t be released further.

I find the information helpful and insightful, as it can shed light on why some species were or were not seen on that trip.

For this reason, the species is evaluated as Vulnerable.” The Rufous-tailed Robin used to be called Swinhoe’s Robin but apparently, somebody decided that there were already too many bird species (6, according to the HBW) named after him.

Now, there are a few obvious uses of bird names that I really needn’t cover, like our ambivalence towards the house sparrow. Its nickname “Spatz” is one of our most common terms of endearment, yet “Dreckspatz” translates to dirt sparrow and describes a person with questionable body hygiene.
