Going nuts for noisy birdsong

SHRILL SQUEALS PROVIDE RHYTHM FOR PARK PATROLS

- Stuart Winter

FULL-BODIED bird song has begun trickling through woodlands before the first buds of spring have chance to unfurl their green credentials.

Mistle thrushes are declaring territories with treetop ballads said to warn of approaching storms.

The sunrise and sunset crooning of song thrushes never sounds repetitive even though notes are delivered in identical couplets.

Great tits, wrens and robins are also joining the arboreal chorus months in advance of springtime's dawn extravaganzas.
