Autumnwatch Unsprung round-up week five
We're over half way! We hope you enjoyed last week's show - we certainly did. If you missed it you can watch Unsprung on BBC iPlayer here.
Doesn't our new location look stunning? Here's a shot researcher Sam took during our rehearsals on the night of the first Slimbridge show.

This week's quiz took the form of a stained glass bird collection. If you haven't already given it a go it's still live.
With our new location comes an exciting new tea cosy crocheted by Autumnwatch enthusiast Lynne Hardman. Here's its beauty shot.

We had lots of fantastic questions, pictures and videos from you all last week and one of our favourites was from Ian W who wanted to know why these geese were flying upside down! This behaviour is called whiffling and wildfowl often do this when coming into land. As Chris said, when they turn their bodies upside down they become very unaerodynamic allowing them to drop quickly from the sky.
Thomas (aged 6) wanted to know what the loudest bird call is. It's thought that the farthest carrying bird call in the UK comes from the bittern. A bittern's booming call can be heard up to three miles away. (Watch a clip of a bittern booming from the BBC's archives here.) Where most birds use their voicebox syrinx to make their call the bittern actually makes its sound by expelling air through its oesophagus.
The loudest bird in the world is thought to be the superb lyrebird which also has the most extraordinary ability to mimic other bird songs and even man-made sounds. You can watch an awesome clip of a lyrebird's repertoire here. Chris also noted that nightingales can sing extraordinarily loudly and scientists in Berlin once recorded one at 95 decibels - that's outside the European sound pollution regulation limits!
And finally, we featured a lot of your videos this week and here's our favourite from John Tattersall:
If you've got any questions for next week's Unsprung let us know by commenting below. We love seeing your pictures of autumn wildlife so add them to the Autumnwatch photo group, or if you're more handy with a camcorder then upload your wildlife home movies.
