August Wheat

The weekend was very windy with almost northerly gales at times and frequent bouts of rain. So I waited until Monday lunch time before a spot of birding along the sea wall at Pilling, perhaps not the best choice as the tide was out and it was still windy. There are very few birds to report except that I did catch my first two Wheatears of this autumn. 

Buzzards were at Fluke Hall again, two feeding in the potato field where they pick through the recently harvested earth and the remaining crop for earthworms and such like. I’d hardly set foot along the sea wall before the Buzzards saw me coming and headed off out of sight. Later there was another Buzzard at Pilling Water which flew towards Fluke Hall, so possibly number three. 

The Buzzards gave way to a Kestrel which hovered above the sea wall for a while until it too flew to the south of the woodland, and later a definite second Kestrel, this one flying back towards Damside.

Along Pilling Water, 2 Grey Heron, and out on the marsh 3 Little Egret. Passerines were few and far in the still strong wind with a smattering of Linnets maybe 20 in total, 7 Goldfinch, 1 Pied Wagtail, and 20+ Tree Sparrows at Fluke Hall. 

At Piling Water were 3 Wheatears, an adult and 2 juveniles, the juveniles sticking together but the adult some way off. Of two birds caught one was an adult female still in post-breeding moult, the other was one of the two juveniles. The adult had a wing length of 93mm and a weight of 24.1 grams so a nominate Oenanthe oenanthe. The noticeable bulkier juvenile weighed 28.9 grams with a wing chord of 99mm, and therefore a possible leucorhoa “Greenland“ type.

Greenland Bound

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.

There are more birds and bird pictures soon from Another Bird Blog. Log in tomorrow and see "what's about".

A Windy Wheat

It was pretty windy out Pilling Way this morning but something made me head off towards Pilling Water again hoping for a Wheatear or two to relieve the non-ringing days of late. Just a single bird today feeding in the sheltered stones, proving easier to catch than a whole gang of them urging each other on to migrate as per yesterday. Today’s hungry juvenile had a whopping wing length of 112mm, so an obvious Oenanthe oenanthe leucorhoa , but I had to find a sheltered spot for the portrait.

In the conditions there wasn’t much else of note: similar numbers of Pink-footed Goose at c5000 but 8/10 Barnacle Geese mixed with the distant flock, 1 Kestrel, 1 Peregrine, 40+ Goldfinch, 2 Pied Wagtail, 3 Meadow Pipit, 2 Little Egret. 

After, and in the hope there might be less wind, I thought I’d best go to Rawcliffe Moss to see if the low-lying farm track was negotiable and further up the farm, if my peaty, muddy parking spot was reasonably solid. If the answer to both questions was “yes”, I planned a top up the Niger feeders followed by a wander about. 

A long section of the track proved pretty deep in water, and then the parking location an uninviting pool of squashy black mud, but the GV did the business without trouble and then donning wellies I set off for a gander. 

There’s still a roving flock of Goldfinches about, their numbers gradually falling with c 40 today, at least 8 of them finding their way to the Niger food in the net rides where I topped the almost empty feeders up. It’s been almost impossible to get to the site in the last week with the continual rain and locally flooded roads but on the first half decent day a ringing session will ensue. The time was almost 11am but a few each of Siskin, Chaffinch and Meadow Pipit flew over, obvious remnants of any the morning’s migration but the steady breeze all morning had been too strong for ringing.

On the floods I found 6 Pied Wagtails and a few more Meadow Pipits, but with the wind picking up the open mossland isn’t the best place to linger. On the way off the farm I clocked a Kestrel, a Buzzard and grabbed a shot of the local Robin which hangs around for seed spills. Clever animals these birds.

Saturday and Sunday look breezy again, so fingers crossed for better weather and more birds soon on Another Bird Blog.
