One of Britain’s remarkable winter wildlife spectacles is rarely glimpsed by humans. On bitterly cold nights, long-tailed tits will line up on a branch deep inside a thick hedge or bush, nestled together for warmth. The roosts contain related individuals, often adults and their offspring. By day, these family parties are much more public, drawing attention to themselves with high-pitched volleys of slurring ‘srih-srih-srih’ calls.
