Wren

Up here on the Lancashire coast March lived up to that old adage of “In like a lion, out like a lamb”. At the moment the Atlantic Jet Stream sits over us like a heavy wet blanket bringing just this morning a hoolie of wind, rain, sleet and hail, plus a dollop of sunshine. The few brief days that promised spring are but a distant memory as we settle in for another week of foul weather. 

With little chance of ringing or birding for a day or two, here’s a note or two about a very common but mostly forgotten species. 

In those few hints of spring I’d heard the familiar loud and rapid chatter of the diminutive Wren, one in song then quickly followed by a reply from the second. I knew it was territory time. Wrens are famously good singers, and a male will duet so as to sing down and hopefully silence a nearby rival. 

On one of my dashes to the garage freezer this week I disturbed a Wren taking dried up material from the base of last year’s hanging basket. I watched as the Wren scuttled off along the fence like a clockwork mouse and promptly disappeared into the ivy covered hedge that separates us from next door.  Nest-building already, but maybe not for real as the Wren is one of those species known to build “cock nests”, a nest built by a male bird as part of the courtship ritual. Several such nests may be built by one male, one of which will be selected by the female.

The Wren’s scientific name of Troglodytes troglodytes is Greek "troglodytes" ("trogle" a hole, and "dyein" to creep), meaning "cave-dweller", and refers to its habit of disappearing into cavities or crevices whilst hunting insects or to roost. Many a Wren nest looks much like a cave, dark and forbidding with a just tiny entrance hole where none but the brave dare enter.

I often feel rather sorry for the common Wren, neglected by birders and barely mentioned because it has no rarity value. Depending upon which book or Internet page read, the Wren is one of the commonest and most widely distributed British birds with breeding pairs estimated at 7–8.5 million. 

The Wren population is generally sedentary but perhaps surprisingly, there are a number of recoveries to and from the near Continent and Scandinavia. Our own ringing group has a database of almost 3000 Wren captures that show few if any migratory tendencies but some evidence of the species longevity of up to 6 years. 

When winter weather hits hard Wrens can become penguin-like by huddling together for warmth. In the winter of 1969 a Norfolk nest box was found to contain 61 Wrens. Such severe but fortunately rare winters can finish off anything from a quarter to three-quarters of the Wren population. Hence the reason that a Wren lays between 5 and 7 eggs at a time and a pair can rear two broods of chicks in a single year. 

The Wren is unloved by most bird ringers as an annoyance in a mist net as it twists and turns through the mesh in its eagerness to go nowhere. Should the ringer fail to take charge of the initial encounter, the open cuffs of a shirt or jumper provide another handy crevice or cavity into which the Wren will quickly escape. When using a car as a ringing base and processing a wriggling Wren, a ringer is well advised to close all doors including the rear hatch. An open car door is a large, open and welcoming cave to a Wren; even more so are the nooks and crannies of a vehicle dashboard.

In 2015 the Wren never made it to be the most loved British Bird when in a national poll involving over 200,000 people the Wren languished fourth behind the Blackbird in third place, the runner up Barn Owl and the jubilant Robin.

The English surname of Wren is said to derive from being applied to people who were small, busy, quick and energetic just like our little bird. Sir Christopher Wren is perhaps the most famous, so active and endlessly occupied as to design St Paul’s Cathedral as well as fifty two other churches after the Great Fire of London. And he lived to be ninety-one. 

I am old enough to remember the British farthing (1⁄4d) coin, (from "fourthing"), a unit of currency of one quarter of a penny, now long redundant, but where the Wren found short-lived fame. Recognition came again in 2017 when out little friend appeared on the first-class stamp in a Royal Mail ‘Songbirds’ series.

That's all for now. Wish me and the little Wren luck with that weather.

Linking today to Eileen's Saturday.
