Sweet video footage shows a mother duck guiding her brood through a school to get to a nearby lake.
Staff at Bromley High School, in south east London, captured the adorable scenes which the female mallard repeats every year.
They helped the duck through the reception of the school, which connects to the sheltered courtyard where she safely laid her eggs over winter.
A spokesperson for the school said: ‘In recent years, mature ducks have arrived in the school courtyard in February each year and one duck has had her litter in the quiet of the courtyard.
‘Of course, the mature ducks can fly into the courtyard, but the little ducklings cannot fly out.
‘They are visible to the girls from the corridors and classrooms surrounding the Quad, but we limit use of the Quad so that it is very peaceful whilst the ducks are nesting.’
The video showed more than a dozen babies waddling through the school door, across the building floor and down the steps on the other side.
They then went onto a lake dug by parents in 1981 when the school moved location a couple of miles away to Bickley, which also attracts heron, frogs and newts.
The children enjoy the ducks travelling through their school every year the migration takes place – but appear to have missed it this year as they were not in class at the time.
‘The oohing and aahing is rather overwhelming,’ the spokesperson added.
An independent girls school for around 900 pupils aged from four to 18, Bromley High School was founded in 1883 and costs £5,897 for each pupil every term.
Former pupils at the school include Labour MP Margaret Hodge and EastEnders actor Tilly Keeper, who plays Louise Mitchell in the soap.
