Just noticed, rewatching The Eleventh Hour, that a similar sound of bird song can be heard when the Doctor comes round from being whacked by Amy as in Amy's Choice when the dream status changed/they fell asleep...

Coincidence of something more?

I remember reading something about bird songs and that they have a particular meaning. But what I don't remember is what or where, 'cause I'm useful like that
Although birdsong was quite a strange thing to use.

HEY, Bird Song. River Song! Haha... Well, that's my useful contribution. I'll go now...

Try an anagram of The Dawn Chorus is all I'm saying

Oh you mean

Enough of the fish custard!

Or do you actually mean

i watched TEH over again today as well and heard the birdsong... thought exactly the same thing

Hush down a cert.

Silence will fall !

Are you sure?

or there's also...A Cher shutdown.

Cher's the big bad and she's turning back time

Had wh*re's **** ??

I was pretty sure that birdsong in TEH was meant to sound like what you used to hear when a cartoon character got hit over the head. Tweet tweets, with little birds flying round their heads!

There's birdsong at the beginning of Time of Angels, too, when the bloke who has been put in an hallucinogenic trance by River Song is reeling about.

Please put me out of my misery and tell me what this anagram is.

I put it into an anagram engine and it gave 34268 results

I'm going for Dr Who A **** Hes

Im with Helbore on this, thats exactly how I Saw it, as has always been in cartoons and slapstick. Nothing more than that in my opinion.

what is really spooky is that has appeared in my google toolbar, and I have no idea where from.

Not time for your colonoscopy, is it?

this is totally off topic, but i was just listening to the crazed amount of bird song outside and thinking about how many birds there possible were outside my house, when i scrolled down the 'new posts' page and this was at the bottom :| weirrrrd. maybe its a sign, im probs the next doctor who, lets be honest.

34268 possible anagrams

Come to think of it, there are a lot of distracting unrealistic sound effects. From the cartoon tweets after the head-bash, to the sounds when the Doctor is drawing circles in the air in Flesh and Stone, to the over-loud tapping when he investigates little Amelia's wall.
