Since you went away the days grow long
And soon I'll hear old winter's song
But I miss you most of all my darling
When autumn leaves start to fall
See you all for #Winterwatch in January!
You won't have to wait long for the next 'Watch'. Winterwatch 2016 returns in January at the Mar Lodge Estate in the snowy Cairngorms, 170 miles due north of WWT Caerlaverock.
The Cairngorms provide a unique alpine semi-tundra moorland habitat, home to many rare plants, birds and animals, including red deer, roe deer, mountain hare, pine marten, red squirrel, wild cat and otter, as well as the Cairngorm Reindeer, the only herd of reindeer in the British Isles.
Chris Packham has spent all week looking for a particular bird on site here. When he finally spotted him, he did this...
Watch Chris take Martin Hughes-Games to see a sparrowhawk in the prime of its life...
Not everyone agrees with him though...
Thanks for all your photos and videos over the last few days...
Last week, billions of us around the world observed the familiar ritual of winding our clocks back. Here's a map showing the countries that do and don't manipulate time for daylight savings.
Most animals aren't affected by the arbitrary shifting of handles on a dial. Their natural timekeeping circadian rhythms leaves them free from our meddling.
But there seems to be some evidence that animals that interact with humans can sometimes find the change disruptive. Pets can be left very confused by the changes in their owners' schedules. Other animals feel the impact too - the swans here at Caerlaverock are known to get a bit irate about changes to their feed times.
Martin Hughes-Games heads to a hillside hide on the island of Rùm for another all-night stakeout observing the nocturnal behaviour of the frisky stags.
For all the bluster, it's the girls who are leading the boys around

A few of you are noticing that Chris Packham is continuing his none too subtle James Bond references...
In the last few weeks you may have encountered some many-legged visitors inside your house. As the temperature has started dropping, your central heating is very much appreciated by these creatures.
There are over 650 species of spider in the UK and this time of year is ideal for spider watching from the comfort (or discomfort, if you're arachnophobic) of your own home.
This week, we've been running live cameras on a bird feeder to find out what the local birds most like to fill up on.
We put out an even percentage of sunflower seeds, oat grain and barley grain to appeal to the local farmland birds. We then sat back, eagerly anticipating yellowhammers, tree sparrows and various finches.
We soon found, however, that greenfinches totally dominated the feeder table and gobbled down the sunflower seeds. They didn't touch the other two options.
So we changed it up a bit.
On the live cameras we'd been seeing lots of greenfinches, goldfinches, house sparrows and common garden species such as blue tits, great tits, coal tits and robins. So we decided to put more common garden bird food to the test.
We served up sunflower seeds, sunflower hearts (which is what you get when you crack open a seed) and peanuts.
We found that greenfinches mainly stuck to eating sunflower seeds even though they were being offered the sunflower hearts which are easier to eat and digest. We think this could be because you don't find sunflower hearts in the wild so they probably weren't used to them.
Goldfinches, on the other hand, only ate sunflower hearts. This must be a learned behaviour. They know to go straight for the hearts to get the most energy efficient nutrition fix.
So what did the birds like most overall?
Sunflower seeds were the most popular with 43% being eaten. Then it was sunflower hearts at 38%, and peanuts at 19%.
Triops have changed very little since the time of the dinosaurs and they're found in only two locations that we know of. One of these places if right here in Caerlaverock. These tiny crustaceans, often known as tadpole shrimps are thriving on this reserve.

It's all gone far too quickly, in a few minutes it's the final Autumnwatch of 2015. Tonight we have an A-Z of creatures to make Noah weak at the knees...
Sparrowhawks, dormice, hedgehogs, starlings, tadpole shrimps (aka triops), Hebridean sheep, barnacle geese, roe deer, pintails, greenfinches, spiders, bats, swallows, redwings, jays, basking sharks, tags, swans, foxes, snipes and goosanders and badgers. Phew!
For the last day and a half we've been running a vote to find out your favourite collective noun for our Autumnwatch presenters.
We narrowed your original suggestions down to a short-list of eight - cacophony, enthusiam, equinox, hoot, innuendo, merriment, mischief and ramble.
The poll closed at 7pm and the result is... A TIE!
You were unable to separate 'enthusiasm' and 'hoot' so we gave the casting vote to the studio audience here in Caerlaverock.
And the resounding winner is... HOOT
So there you have it, 'a hoot of Autumnwatch presenters'.
Here is a breakdown of the final results...
We have a dog on Unsprung tonight, called Grace, who in 2012 collected the PDSA Dickin Medal on behalf of another dog Theo, who died of a seizure shortly after her handler was killed in Afghanistan.
The Dickin Medal is the highest award any animal can receive whilst serving in military conflict. It is recognised worldwide as the animals’ Victoria Cross.
The award acknowledges outstanding acts of bravery or devotion to duty displayed by animals serving with the Armed Forces or Civil Defence units in any theatre of war throughout the world.The Medal is a large, bronze medallion bearing the words 'For Gallantry' and 'We Also Serve', It has been awarded 65 times since 1943. Pigeons lead the way on 32, followed by 29 dogs, three horses and one cat.
Grace has recently retired from active service in Afghanistan last year and lives with owner Stuart Campbell, pictured below.

There are almost 250,000 photographs on the Autumnwatch Flickr group, capturing the stunning beauty of the changing season.
We've featured a selection of these incredible images here on this page throughout the week. Thank you to everyone who's contributed to the visual feast!

There has been some confusion today about the whereabouts of Swally the Autumnwatch mascot who has been escorted south from Caerlaverock by members of the public over the past few days. Morning reports on twitter indicated that Swally was Mexico-bound but it now appears that our stuffed toy swallow is off to Australia on Tuesday...
A study has revealed an unnaturally high number of red kites forage in Reading. At this time of year, up to 400 kites arrive every day.
But 25 years ago there were fewer than 100 kites in the whole country. David Lindo investigates the reasons for this increase – and the implications for kites and other species.
Right now, Chris, Michaela and Martin are talking to Lindsay, Barney and Radsey on Blue Peter about all things autumnal.
There's lots to look out for outdoors and CBBC have come up with a seasonal quiz – have you spotted these five key signs that autumn's here?
And as today is bonfire night, don't forget to look after your pets as they can get stressed and anxious by the loud bangs and bright lights of fireworks.
Find out what you can do to help keep your animals happy and relaxed this bonfire night. Read these top tips here.
Michaela Strachan explores the potential dangers wind farms can pose to migrating birds across the UK. In this clip, she talks to Dr Larry Griffin who is researching GPS data on UK bird transit into how and where to place new wind farms.
Our thermal cameras shine a light on rutting by night on the island of Rùm. 'Smooth' the stag is back in charge with a huge harem in tow but can he hang on to all his hinds for the whole night with nemesis 'Enemy 04' sniffing around?
Right now, Brett is talking to Colin Campbell, one of the founders of the centre here at Caerlaverock.
In the 1950s, the numbers of wildfowl - in particular barnacle geese - were extremely low. In 1957, an area of 600 hectares of land in Caerlaverock was declared a National Nature Reserve.
In 1970, The Wildfowl Trust opened a visitor centre at Eastpark Farm in Caerlaverock. In the 1980s the name changed to the Wildfowl and Wetlands Trust (WWT).
Since the reserve was established, the number of barnacle geese has risen dramatically from the 300 barnacle geese in the 1950s to over 40,000 today.
Find out more about WWT Caerlaverock.
Today, Brett's anchoring the 4pm show. He's going to be chatting to Colin Campbell, one of the driving forces behind the foundation of the wildlife reserve here at Caerlaverock which opened its doors in 1971.
Brett will also be catching up with #2minutebeachclean founder Martin Dorey to find out about the latest from this remarkable grassroots project.
We'll also be taking a look at the best of the action from the last four days - the videos, pics and moments that have won us all over.
