First British-ringed Stonechat for Norway - rubicolus?

John Secker from Thetford Forest Ringing Group writes:

Since 2003, Stonechat breeding in the Forestry Commission’s Thetford forest on the Norfolk/Suffolk border have been surveyed. The population has been as high as 56 pairs (2008, after a run of mild winters), and down to just four pairs (2014 after a run of relatively cold winters). In 2006 a project to find nests, and colour-ring both chicks and adults was begun by Thetford Forest Ringing Group.  In total, 750 birds have since been fitted with combinations of three colour rings and a metal BTO ring; 673 have been nestlings, 37 adults and 20 fledglings.

There have been many re-sightings within the forest area and Breckland generally, but also eight from further afield, mostly within East Anglia. The furthest travelled bird being seen near Chingford, East London. But certainly, nothing prepared us for what was to come.

On 27 March 2016 two birders (Odd Kindberg and Fredrik Tjessem) photographed, and reported to the BTO, a colour-ringed female Stonechat, near Tangvall, Sogne, in Southern Norway. The bird had a pink ring above a pale blue on the left leg and metal above pale blue on the right. The combination certainly matched one used in Thetford Forest but all the same, although we could not find any other studies that might have used this combination, we had to wonder whether or not someone closer to Norway may have colour ringing this bird. But from what we could make out from the photos, the metal ring did look tantalisingly like a BTO ring. We got back in touch with the photographers and in no time at all Odd was back on the case and we soon received a new batch of excellent photographs that enabled the entire ring number to be pieced together and therefore rule out any confusion with other studies – BINGO!.



Records showed that this bird was from a nest found by Gavin Chambers in May 2015 near Grimes Graves in Thetford Forest, Norfolk. The chicks were ringed by Ron Hoblyn and me, and the nest fledged successfully. Tangvall is approximately 750 kms North-east of Grimes Graves.
None of the other birds recorded away from Breckland has moved in a north-east or easterly direction.

This is the first ever British-ringed Stonechat to have been reported from Norway. Stonechat was not found breeding in Norway until the 1970’s, when a population of the British race, Saxicola rubicola hibernans established itself. It was speculated that those birds were of Scottish origin, Scotland being the closest part of Britain to southern Norway. But maybe this new record suggests an alternative.

It is possible that the bird became caught up in one of the powerful south-westerly storms that have swept Britain this winter, but perhaps more likely that it made the shorter crossing to the Netherlands and then moved north into Norway. Either way it is a fantastic record and demonstrates the possible rewards to be had from colour-ringing birds.

It will be interesting to find out whether or not this individual stays to breed in Norway.

Is it all over?

We have now reached that part of the season. After the long haul of some incredibly dedicated field work, the time has come when some nest recorders start to wind down. The dawn chorus is now a shadow of its former self and with each passing day there are fewer nests to find. The days of Long-tailed Tit nests in open-mouthed bramble are long gone. The crows' nests lie empty, hidden deep within the leaf canopy of dense trees. Gull chicks are now leaving their nests and some Cuckoos are already in Africa. Our beloved Swifts will soon be leaving our shores and their screaming summer song will be missed.

But it isn't over yet, our team is still getting out there and we continue to nest record. We still have some exciting nesting ahead. We still have the second brood of Reed Warblers to find, we have a Sedge Warbler that should be hatching soon. Tree Pipit, Whinchat, Lesser Redpoll and Stonechat are up on the moors feeding young in the nest. And even better, Mark Penney made a visit last Saturday (19th) and found a new Meadow Pipit with eggs! At our coastal location we have Wren and Yellowhammer on eggs and armed with our Schedule 1 licence, we are right in the middle of conducting an exciting breeding study on the Cirl Bunting. So far we have found 10 nests; six of these have fledged, one brood that I ringed last week just needs one more visit to the nest to record its outcome and we have two still on eggs. These are second brood nests from previously found pairs and one that is building. We have by no means finished yet. We have a trip planned next week for a second brood of Nightjar that could take us well into August.

Locating nests at this time of year can be more difficult and more challenging than earlier in the year when the vegetation is less dense, but the additional effort will add valuable data on late nesting species and timing of events to the Nest Record Scheme database. We may be coming to the end of the nesting season as we reach high summer once again, and our fast awakening autumn yawns its vibrant colours, but there are still many key species to monitor.

I was watching a young Robin just the other day, and I could see its adult plumage beginning to show through. Christmas came to mind, a stark reminder that the winter will soon be upon us and we will long for the nesting season once again. But then I think and smile, it is still the nesting season, and I will enjoy what's left... before the dark winter nights drop on us once again.

Stonechat off to the coast... again

Thetford Forest, on the Norfolk/Suffolk border has a variety of habitats of Special Scientific Importance including woodland and heathland, which supports some scarce bird species like Nightjar, Woodlark and Goshawk. A recent colonist to the forest has been the Stonechat, and Thetford Forest Ringing Group has been studying this species, monitoring its movements and demography since its arrival.

Stonechat started to breed about 7 or 8 years ago and increased to about 56 pairs. After the recent cold winters the number of pairs has decreased dramatically to about 20 pairs. Adults and chicks have been colour ringed as part of a Retrap Adults for Survival (RAS) project with the aim of finding out where they go during the winter and to monitor the dispersal of chicks.

Most of the birds move out of the forest in the winter, resulting in some interesting movements (blue pins) of birds to the milder coast. See map below.

We have just heard from Trevor Girling (North West Norfolk Ringing Group) that a colour ringed female Stonechat has been seen at Snettisham Country Park (green pin) on Thursday 24th March. This bird was ringed as a chick by John Secker (Thetford Forest Ringing Group) at Hockwold (red pin) on 07/06/2010 and amazingly Trevor was overseeing this bird being ringed!

It looks like this bird has now set up home at Snettisham with an unringed male and its progress will be followed by the N W Norfolk Ringing Group. Stonechat don't usually travel very far but these sightings are providing vital information about their movements.
