Bearded Tit or Bearded Reedling Notes:-

 

The bearded reedling is a small, sexually dimorphic reed-bed passerine bird. It is frequently known as the bearded tit, due to some similarities to the long-tailed tit, or the bearded parrotbill. It is the only species in the family Panuridae. Wikipedia

 

Scientific name: Panurus biarmicus

 

 

1. Not a bearded tit

 

Despite its name, the bearded tit is neither bearded nor a tit! It actually has a moustachioed-look to its plumage and for a while it was considered a member of the parrotbill family, but now it is thought to be more closely related to larks.

 

2. Reed bed inhabitant

 

Bearded tits are the only British songbird to stay in reed beds all year round. Originally they were limited by the availability of reed beds in Britain, but thanks to newly created or expanded reed beds, they are now more widespread and can be found in parts of eastern and southern England, Morecambe Bay in northwest England and around the Tay estuary in Scotland.

 

3. Occasional movements

 

Although bearded tits are not well known for migration, there is some movement in the autumn through local dispersal. On occasion, there is also an influx of continental birds from mainland Europe. They are more gregarious outside of the breeding season, and therefore tend to be easier to see.

 

4. Breeding behaviour

 

There are only around 630 breeding pairs of bearded tits found in Britain, most likely due to the fact that they are limited by habitat. They build their nests low down in the reeds, often on piles of dead reed stems. They will use specially designed nest boxes, which were created to bypass their susceptibility to flooding. They are prolific breeders that can have up to four broods a year, with four to eight eggs per brood!

5. Alterations

 

Bearded tits survive in the reedbeds all year round by changing their diet from insects during the spring and summer, to seeds in the autumn and winter. They cope with this by altering their gut morphology, and by eating large amounts of grit particles that help to grind down the tough seed fibres.

 

6. Vulnerability

 

Due to their range restriction, bearded tit populations can be vulnerable to particularly harsh winters, flooding and saltwater inundation into reedbeds. As a result local extinctions can occur. For example, in the cold winter of 1947 the East Anglian population decreased to just four or five pairs in Suffolk and a lone male in Norfolk. It is thought that the snow cover prevented them from accessing the seeds they needed to survive.

 

7. ‘Moustachioed tits’

 

Bearded tits are sandy brown with long tails, yellow bills and eyes. The males have grey heads with a conspicuous black ‘moustache’ that flanks the throat. Females are duller and lack the moustache. They have a distinctive ‘ping’ call when they fly, which you will usually hear before you see them.
