The Weather Channel, who is the expert in seasonal phenomena, has identified top ten signs of Spring to look out for as the UK starts to experience milder weather:

1) Daffodils: 'Narcissus', most commonly known as the 'daffodil', bloom in early to late spring and are one of the most well-known emblems of Spring.

2) Catkins: These incredible flower clusters are usually seen on woody shrubs and trees including oak, alder, beech and poplar.

4) Frogspawn: Frogs return to ponds around February/March time each year to lay their spawn. If you spot spawn in the water, there's no doubt that Spring has arrived.

5) Bird song: There's nothing quite like the sound of birds chirping away in the trees; as soon as you hear the dawn chorus, this signifies breeding time and is a sure sign that Spring is on its way.

6) Primroses: Pretty primroses can be found in a variety of colours and sizes as the Winter season ends, usually popping up in open woods and shaded hedgerows.

10) Spring Lambs: As the Winter months come to an end, countryside fields will be breaming with young lambs jumping and darting around trying to find their feet.
