Bearded Tit
Panurus biarmicus (Linnaeus, 1758)
BR
BEATI
13640
Family: Passeriformes > Panuridae
The extraordinary colours, shape and calls of this small, reed-dwelling bird are quite unlike any other British species. It is related only distantly to other tit species.
Bearded Tits can be found year-round in large reed beds across England, Wales and the Tayside area of Scotland. Their long tail, rich auburn plumage, grey head and black moustachial stripe (or 'beard') are distinctive. In autumn, birds may be seen 'feeding' on grit, which helps to facilitate their switch from a summer diet of reedbed insects to one mostly of reed seeds in the winter.
Bearded Tit numbers were severely reduced by long, cold winters in the 20th century, and the species became restricted to a handful of sites in East Anglia and Kent. The species has since increased hugely in both numbers and range, and appears less susceptible to hard weather.

CONSERVATION STATUS
This species can be found on the following statutory and conservation listings and schedules.
POPULATION CHANGE
Bearded Tit is a specialist which breeds in reed-beds, and consequently many of its breeding sites are on nature reserves where they are well-monitored and reported to the Rare Breeding Birds Panel. The population is around 700 pairs (five-year mean of 673 pairs for the period 2015–2019) and has almost doubled over the 25 years to 2019 although annual fluctuations can occur due to severe winter weather (Eaton et al. 2021). The breeding range in Britain expanded by 84% between 1968–72 and 2008–11 and the species now breeds in both Scotland and Wales (Balmer et al. 2013)
DISTRIBUTION
Bearded Tits are dependent on extensive Phragmites-dominated reedbeds and in 2007–11 they were found mostly in East Anglia and on the English south coast, with small isolated populations elsewhere, including in Wales and southern Scotland. Newly created or expanded reedbeds in Somerset, South Yorkshire and the East Anglian Fens have been readily colonised.

SEASONALITY
Bearded Tit is recorded year-round; detections increase in autumn when irruptive parties can appear in atypical locations.

CAUSES AND SOLUTIONS
Causes of change
Bearded Tits depend on Phragmites reedbeds and therefore habitat availability is likely to limit their distribution (Balmer et al. 2013). The creation and restoration of reedbeds over the last fifty years to help other specialist species, such as Bittern, is therefore likely to have helped drive population increases. Bearded Tits may be affected by severe weather (e.g. Wilson & Peach 2006) so it is also conceivable that climate change may also have benefited the species.
