Song Thrushes break the silence

Song Thrush (c. Brian Johnston)

What a lovely calm, bright day we had after all the rain.

Before first light  I was out the back garden and was delighted to hear at least two Song Thrushes in full song. (they are still singing at last light too!)
I presume the colder and brighter conditions are a trigger to bird song: it really punctuates the still air and the Song Thrush is probably our finest songster: clear and loud, they repeat the notes, just in case you missed them the first time! 

We tend to think of Song Thrushes as residents and a singing bird in winter surely is, but we get winter influxes of Song Thrushes along with the Redwings from northern Europe.  The latter are more obvious as they are gregarious in nature and appear only in winter.  Migrant Song Thrushes and Blackbirds usually get 'bumped' around the garden by the residents and bird song reinforces the residents claims to a territory.

Anthony Mc Geehan, writing in Birds of The Homeplace (available from BirdWatch Ireland), highlights R.M. Barringtons observations at Irish Lighthouses: in correspondence with light keepers, he noted very large numbers of Song Thrushes striking the light at Tuskar Rock, off the Wexford coast in late autumn.  It is true we are more accustomed to logging the thin contact calls of Redwings at night, indeed tonights weather will be ideal for listening out for migrating Thrushes, cold and foggy and as yet, not much wind...

All very welcome activity as the start up to the Garden Bird Survey is only 10 days away; who said the winter is dull?
