I wasn’t too sure about this morning’s first Wheatear, a second year male with lots of last year’s brown juvenile feathers on the crown and ear coverts. At first it both felt and looked rather bulky, but its weight was in line with ones caught recently, the wing measurement longer at 105mm. The weight of 26 grams was slightly above those of last week although upon closer examination there wasn’t a hint of excess fat; in fact the poor thing seemed a little on the skinny side. There are no midnight snacks or raiding the fridge during a Wheatear’s overnight journey.

The second bird was a “Greenland” before I even took it from the trap. Big and bright this adult male easily met the biometric parameters for Oenanthe oenanthe leucorhoa, the large and colourful so called “Greenland” race of Northern Wheatear. Its wing measurement of 116mm was equal to that of a Redwing or a Song Thrush, it had a smidgen of migratory fat in the furculum and weighed in at 29.8 grams. What a cracker of a bird!

Wiki's summary is superb.
"The Northern Wheatear makes one of the longest journeys of any small bird, crossing ocean, ice, and desert. It migrates from Sub-Saharan Africa in Spring over a vast area of the northern hemisphere that includes northern and central Asia, Europe, Greenland, Alaska, and parts of Canada.
Birds of the large, bright Greenland race, leucorhoa, makes one of the longest transoceanic crossings of any passerine. In spring most migrate along a route (commonly used by waders and waterfowl) from Africa via continental Europe, the British Isles, and Iceland to Greenland. However, autumn sightings from ships suggest that some birds cross the North Atlantic directly from Canada and Greenland to southwest Europe, a distance of up to 2500 km).
Birds breeding in eastern Canada are thought to fly from Baffin Island and Newfoundland via Greenland, Ireland, and Portugal to the Azores (crossing 3500 km of the North Atlantic) before flying onwards to Africa. Other populations from western Canada and Alaska migrate by flying over much of Eurasia to Africa.
Miniature tracking devices have recently shown that the Northern Wheatear has one of the longest migratory flights known - 30,000 km from sub-Saharan Africa to their Arctic breeding grounds."
A blogging pal in Ontario offered to swap a few Blue Jays and Cardinals for a Northern Wheatear. David, I sent two Wheatears in your direction this morning, last seen heading quickly North and West and so coming your way soon. I’ll settle for an autumn warbler thanks and on the blue theme, a Cerulean would be rather nice.

Things were quiet along the sea wall this morning, the overcast conditions not conducive to migration even though the 7 or 8 Wheatears I saw obviously found a way through the gloom.
At Lane Ends I heard and saw my first Willow Warbler of the Spring with the now regular Chiffchaff in good voice. A Lesser Redpoll, a few Meadow Pipits and Linnets flew east, and apart from 4 Skylarks that was it.
On the wildfowler’s pools are reasonable numbers of Teal, 19 or 20 birds which fly out to the salt marsh when disturbed, while the group of 9 Shoveler circle for a while before returning to the pools.
