Both Song Thrush and Mistle Thrush are currently brightening up the grey January mornings with the far-carrying songs; but how to tell them apart when they're not singing? The BTO have put together an excellent guide to identifying Song & Mistle Thrushes.
If you have Song Thrushes or Mistle Thrushes visiting your garden — or any other birds, for that matter — and would like to contribute your garden bird sightings to help the BTO monitor changing trends in garden wildlife, why not sign up for BTO's Garden BirdWatch? Details of Garden BirdWatch can be found online: http://www.bto.org/volunteer-surveys/gbw/join or email firstname.lastname@example.org
BTO have also put together a thrush masterclass video:
If you enjoyed the video, you might like to take a look at British Birds Video Guide from where much of the footage originated.
