Birdwatch: Mystery of migrating whinchat numbers
They have been seen all along the east coast and inland as their long journey back to winter quarters south of the Sahara gets underway.
There was a record count for the reserve of 18 whinchat at North Duffield Carrs, part of Natural England’s Lower Derwent Valley reserve between York and Selby. Two of them were caught and ringed.

Whinchats were once a very common bird over the whole of Britain, nesting on any available patch of rough ground, even railway embankments.
But now they have disappeared as a breeding bird over huge swathes of southern England apart from isolated breeding colonies on Exmoor and Dartmoor and Salisbury Plain.
They have also left some of their sites in the Pennines and their remaining strongholds are in Wales, North West England and Scotland where they frequent stands of gorse – whin is the Old English name for this plant.

In this country there are no obvious reasons for the continued decline.
The whinchat, like many other birds that migrate to Africa, seems to be experiencing problems either on migration or after its arrival back in Africa.
The stonechat, the whinchat’s closest relative has trebled in numbers since 1995 while the whinchat has declined by 45 per cent.

Skua numbers have been building up along the Yorkshire coast with all four species reported, including a pomarine skua seen from the RSPB cruise from Bridlington on Saturday, and pomarine and long-tailed skuas seen off Spurn. An Arctic skua was seen 15 miles inland at Hutton Cranswick near Driffield,
More sooty shearwater have been moving down the East Coast with sightings off Flamborough and Filey and Spurn where a Cory’s shearwater was also reported.
An adult Sabine’s gull was seen off Flamborough, Kilnsea and Spurn.

Three curlew sandpipers and three little stints were seen at Fairburn Ings while a pectoral sandpiper was seen at the RSPB’s Saltholme reserve on Teesside.
There were also three curlew sandpipers at the Blacktoft Sands reserve. Other waders included 17 spotted redshanks, 25 ruff and a wood sandpiper.
A ringtail hen harrier has been coming in to roost at Blacktoft with the reserve’s marsh harriers while a merlin and two hobbies have also been seen. A Cetti’s warbler is also back on the reserve.
At least one osprey continues to be seen around Hatfield Moors, South Yorkshire while three have been seen around the Fairburn Ings and Swillington Ings reserves. Two whooper swans were seen at Wykeham Lake near Scarborough.
