REDWINGS AT ROOST

I’ve always had fascinations towards our visiting winter thrushes especially in regards to Redwing and Fieldfare. I think it could well be that these species in particular are every vismigger’s dream with visions of the big day movements passing through their local recording areas.

Today I wish to turn to the Redwing and in particular to its roosting records. Once the main migration has started from say the middle of October through to early November, and from then on throughout the winter months, the birds can sometimes be seen roosting on Hutton Roof.  If I take the footpath which goes from the Plain Quarry Car Park and up through Dalton Crags there is every chance I may see some of the roosting birds from the previous evening, as a rule I would not expect numbers to be in excess of 100 birds, so I guess in volume “ours” could be considered a small roost.

On another occasion I remember one year following the birds and finding their small roost at the top of Dalton Crags (North West Side) near to the wall boundary with Lancelot Clark Storth.  I witnessed them going down into a medium sized Pine tree with a couple more smaller trees close by. I watched them for over one hour and noted that they were restless and moving low all the time from there to other trees perhaps 50-100 yards away and eventually coming back and settling into the Pine Tree.  Of particular interest to me was the calls they were making, it was a contact call I had never heard before, which to me seemed totally alien to what you may have expected from a Redwing, more of a gruff sort of call.  On arriving back home I searched online  the many variant calls and did eventually find the call in question.  Sure enough it turned out to be a “roosting contact call” which is only ever delivered at or near to the roost site. I think this particular roosting site was very temporary, and although I did see the same area being used the following year I can’t say I have ever seen it being used since. But I have to say it was lovely to watch even though it may have been of a very small number of birds in this particular roost site.
Another splendid occasion I would like to recall was on Sunday October 10th 2010.  It was 1800hrs and close to dusk when we arrived at the B.A.P. Memorial seat half way up Lancelot Clark Storth. Immediately on arrival we noticed large parties of Redwings going overhead, some really low down, we had no idea how long this had been going on before our arrival, but they just kept on coming for 35 minutes or so even though it was starting to get dark. I noticed all the birds were coming in from a SE direction and making out to a NW direction, the wind that day was East 5-8mph. I had no idea whether this had been an “all day” movement from the birds, but considering the time of the day, it did make me wonder if perhaps they were heading to a roost somewhere nearby!  I went up to the same spot over the next night or two but the situation was never repeated, so maybe they were just moving through our area. Just for the record that experience consisted of a Redwing count of 1472 birds in thirty three parties, with some parties containing numbers between 100 and 170 birds.

A incredible spectacle with 30,000 birds entering a Lancashire roost site

All that may sound good! And yes I feel they are special memories, but let me now try and give my account of just what went on yesterday (18th November 2019).  When we were so privileged to witness what must be a very special phenomenom in regards to Redwing roost and because of its nature gave me the inspiration to write this short article.

I would like to mention that this roost has been established from at least 4th November 2019 and possibly earlier! thanks to Pete Morris and his colleague Kris McBride for stumbling on this activity and allowing us all to share the wealth...


I guess the importance of this special roost will be very difficult to comprehend, or that’s the way I find it.  I have never even heard of a Redwing roost in numbers in excess of the 10k mark.  You need to say to yourself where on earth could 30,000 birds have come from, I would have thought that is about the amount of birds left within the whole of the UK at any one time and could not be representative of this local area, but obviously not!  Looking at it as logical as I can behold they must have come from the local surrounding areas of the Ribble Valley and possibly other nearby areas like the Trough of Bowland, maybe Burnley, Blackburn, Accrington, Rossendale – who really knows? Does anyone know?  For all we know they could have come from even further afield.

Where on earth do 30,000 birds hide during the daytime? Surely somebody somewhere should be seeing fields full of them, or maybe hawthorn trees laden down with them and what about dusk, will people be reporting seeing such volumes of birds going through their particular patch? Is there a pre-roost somewhere fairly close and we are missing it?

The true phenomenon just as it happened before our very eyes

A friend from down in East Lancs phoned me to tell me about a massive Redwing roost site which had been discovered down in the Ribble Valley at a place called Birdy Brow, Kemple End, near Bashall Eaves, an area on the side of Longridge Fell and not far from Hodder Bridge (River Hodder) or the ancient Stoneyhurst or Clitheroe. It sounded really special with reports of over 20 thousand birds going into the conifer roost which to us sounded too irresistible to miss out on. So Sandra and I decided that was our destination, we just had to go and witness this fine spectacle. We were not to be disappointed we arrived on site for about 1545hrs and by 1605hrs everything was in full swing with large sways of birds coming through thick in numbers from a South/South West direction, it soon became obvious we were at the best location to receive the main concentration overhead which was conveniently a small car park, but also the birds were coming through strong at another point almost 100 yards on a wider line to the west, by now the birds were almost just one large continual stream and each second or two saw a hundred or more birds within your single viewing and this just kept building and building in numbers with equal or more continuity, which continued over a period of some 25 minutes or so.  I guess there would have been at least thirty thousand Redwing if not more! I know that sounds incredible numbers for thrushes, but sure enough it happened before our very eyes. Also we noted up to 30 or so Blackbirds which sort of flew just slightly beneath the Redwing flock and I am sure there would also have been hundreds of Song Thrush as well within the massive flock and guess what? There was at least one Peregrine in sight at times spooking the Redwing before all went quiet, and probably a sign he must have got his supper! There were also other birds of prey lining up for a piece of the action which included Sparrowhawks, a couple of Buzzards as well. This today was something really rare and special and I believe this roost has already been going on for several days now……Just a bonus or what!  but has the Redwings started to thin out at a point of almost darkness, a few Woodcock were seen coming out of the areas close to where the Redwing were entering, obviously leaving their daytime roost to go foraging and we witnessed at least 8 birds but I am sure this would have been well under estimated.



Site visits (Monday 18th, Friday 22nd and Friday 29th November 2019)

I again visited the site on Friday 29th November 2019 (my third visit) and got there early so I could take a few photos of the area and map out the actual roosting areas. Check photos below. It had been a clear day with dying blue skies and very cold, so maybe if anything the birds started coming in a little later, but the main activity was going strong by 1605hrs and continued through until at least 1630hrs. Prior to the Redwing coming through I noticed up to a score of Chaffinch also using the roost, these came through in dribs and drabs (mainly pairs). We had a good showing of the Redwing but if anything for me maybe a little subdued in numbers compared to my two previous visits. Also it was clear to see that the birds were more biased to the South side of the car park (far more so than usual). Another fine spectacle to finish off with was seeing up to 12 Woodcock leaving their roost on the edge of darkness.

Other interesting reports

A good friend of mine did go the following evening (Sat Nov 30th 2019) and reported that numbers seemed to be back to normal and the approach over the car park resumed to its best! - More interesting updates below:

27th November 2019 by friend Michael Finch who quoted to me "Earlier today I was in the South Lancs making my way back to Ribchester via Salmesbury. At about 3.10pm several small groups of Redwing (70-100 per group I'd guess) moved across the fields in the general direction of Longridge Fell, several miles away but visible.  I drove straight to Kemple End and sure enough at about 3.45pm Redwings had started to come to roost.  Of course they may have been a different group. They still seem to be coming through in large numbers. 

 Will the roost remain throughout the Winter?


Will this roost carry on for the full length of the Winter months? Whilst at Kemple End the other evening I was told by a gentleman (a retired ringer) that he used to regularly check out a redwing roost site at a Garden Centre, down in Bury, Greater Manchester many years ago and that particular roost had up to 10k of birds coming in nightly and continued to last for the full length of Winter



A coincidence or not - 2019 shows a terrific berry yield!

Do you think perhaps the terrific berry yield this year especially with the Haws may play some part in the extroadinary numbers of birds still hanging about this year and in turn having something to do with the high numbers at roost ?

Roost awakening!

Would it again be such a spectacle to see the birds leaving the roost, early morning, yes it would! although going off the experiences I have had with the smaller roost, the birds (Redwing, very much unlike Starling) don't usually leave the roost sites in one go! whereby they leave the roost in smaller parties and the vacation may take up to one or more hours, I just wonder if this is similar with these massive roost. 

Redwing - substantial historic roost records.....

In late November 2009, it was estimated that 60,000 Redwing were roosting in Broomy Enclosure (New Forest), whilst in late 2010 - 15,000 were recorded flying into Long Beach Enclosure. (information from: New Forest Explorers Guide)

Can be seen soon on BBC Winterwatch

The spectacle was filmed on selected dates between the 20th - 30th November and I do believe they got some good shots which can be seen on the next series of BBC "Winterwatch" transmission JANUARY 2020...
