Dunnock
Prunella modularis
Jernspurven, også kaldet brunellen, er en lille spurvefugl, der oftest lever en skjult tilværelse i skove og krat. Den er udbredt i hele den tempererede del af Europa og i dele af Asien.
Small, unobtrusive bird: lead-grey head and breast, streaked brown back and a thin, pointed dark bill — the fine insect-eater’s bill is what separates it from the sparrows.
Can be confused with
- House Sparrow — House Sparrow has a thick conical seed bill and lacks the Dunnock’s lead-grey head and breast; the Dunnock’s bill is thin and pointed.
Plumage and variation
Male and female: Sexes alike.
Juvenile: Juvenile is browner on the head, looser and fluffier in plumage, and more obviously streaked.
Voice
The song is a fast, thin, tinkling warble — like a little machine; the call a shrill, persistent "tseep".
Behaviour
Feeds shuffling on the ground under bushes, often with nervous wing-flicks — especially in territorial disputes. The mating system is famously flexible; one female may keep several males.
When and where
A common breeder of mixed and coniferous woods with some 50,000 pairs (2011); common at feeders in mild winters.
