It was the week of the tenth anniversary of my first sight of a russet sparrow when I took the featured photo. I think I’ve seen this bird on all our trips to the Himalayas, from Arunachal in the east to Himachal in the west. I’ve been following common usage to identify it as the Passer rutilans. The first person to publish a description of a bird gets priority in naming it. It seems that there was a forgotten dispute about first description which was originally resolved one way. But new historical research shows that it should have been resolved differently. So, it seems one should refer to this bird as the cinnamon sparrow or Passer cinnamomeus.
It is an interesting story. Coenraad Jacob Temminck was the first director of the National Museum of Natural History in Leiden from 1820 until his death in 1858. He inherited a collection of stuffed birds from his father, who was a treasurer of the Dutch East India Company and had strong connections with Asia. He published a description of many birds and animals, including the russet sparrow, to which he gave the name rutilans. The description of the russet sparrow was published in a volume of a book which was dated 1835.
John Gould was an expert taxidermist (famous for helping Darwin to identify finches) and the first curator of the museum of the Zoological Society of London from 1827. The Society obtained a collection of birds from the Himalayas. Gould described this lot, including the russet sparrow, which he called the cinnamomeus. The report was published in the Society’s proceedings dated 1835, but it was published on 8th April 1836. Now it turns out that Temminck’s book also appeared some time in 1836, and, since the date is not exactly known, by common convention it must be taken to be 31st of December, 1836. So Temminck is dismissed by a technicality and the sparrow must now be called a cinnamon sparrow.
Looking at the photo I wonder now about a detail I had not noticed then: what are the blue flowers in the lower corner of the photo? Could it be the rare Himalayan gentian? Probably not, because that flowers in the monsoon, and this photo was taken in late spring. There are not too many tiny blue flowers at an altitude of 2.2 Kilometers above sea level, so this should be easy to place. Unfortunately, I haven’t managed to.
