A species of Wren.

I do know what species of Wren this is but as it’s Throwback Thursday it gives me an opportunity to illustrate a problem captioning certain photos.

The photo was taken in Cheshire, England in the 1980s. In those days most British field guides gave the common English name as Wren. A few would call it a Winter Wren as it was classified as the same species as the North American Winter Wren.

However, over the past couple of decades scientists have been DNA testing lots of species which has resulted in quite a few being reclassified. What was a Wren or Winter Wren in Britain is now a separate species, the Eurasian Wren. The North American Winter Wren has been split into two species. It’s still the Winter Wren in central and eastern North America but the birds down the west coast are now called the Pacific Wren.

To make matters even more complicated the splitting of the various species means new scientific names for some. As my standard photo caption includes both the common English name and the scientific name it means that quite a high percentage of the birds I have on film now have inaccurate captions written on the slide mounts.

So to the photo. It shows an adult Eurasian Wren emerging from a nestbox. An unusual nest site for the species which normally prefers to build a nest hidden in vegetation.

Jenny Wren is a common English name.
