Moving times for the boidz....

The migration is in full swing.... first we had the Cranes [see the post for Feb 23rd].... but ever since we have noticed little and large bunches or lines of birds flying over.
And this is without actively looking out for them.

Some will be birds flying North'ish to get to their breeding grounds... I write "'ish" there because a lot of them.... some LBJs, some thrush-like, at least two groups of large waders and Tuesday morning a very large skein of geese.... have not been heading diagonally across and over us South to North.... rather WWSW to EENE, along the valley towards Petit Pressigny. They might, therefore, be following the river as a navigational aid.... even with all the management work taking place, the actual course of the Aigronne will not have changed appreciably in our lifetimes and those of our ancestors.... so, to a relatively short-lived bird, it is a fixed aid.

Part of the skein of Brents... click to enlarge... the inset then shows the white 'flash' at the back.
The geese, small, stocky and black with a white patch on the side, were Brent Geese [Branta bernicla] Bernache cravant... leaving the Bay of Biscay and the Marais Poitevin and heading inland before eventually swinging north towards Norway, Finland and Northern territories of Russia. The waders, probably Black-tailed Godwits [going on size], were possibly using a similar route....

And there have been more noticeable changes, too, around the house....

Vanishing... Robins... our winter ones probably sing with Breton or even Kentish accents. We don't seem to have Robins around here in the summer.

Arriving... Black Redstart and Stonechat... the males making themselves very obvious on the tops of walls and potager posts, White Wagtail wagging around, Warblers flycatching from bief side bushes...

White Wagtail male gathering nesting material...

We will probably notice later that Greenfinch and Goldfinch numbers have decreased as they move to their breeding territory and use the feeders less.

My feeder...FILL IT!!
OK...MY millet, then!

"Such ill-manners", said Mr Creosote...

And changes in attitude... birds that are normally feeding quietly are now getting more aggressive with each other... male Chaffinches, Sparrows and Tits spend a lot of time just chasing around... not just trying to get someone else off the feeder, but really trying to get them out of the tree.

Even the Moorhens have been becoming more territorial... chasing the juveniles away... especially the male, he's the worst. There is a difference between the sexes that is not in the books... the male Moorhen has a larger red plate above the bill... noticeable when they are together under the feeder... broader and slightly higher up the forehead than the female. There is, however, a difference... possibly only in the breeding season.... between the two sexes in the tail... the male cannot seem to be able to tuck the white outer feathers away... so, when viewed from the front, even if you can't distinguish the difference in the plate, the male is the one who goes around with the tail more erect with the white showing. Even one of the juveniles.... the one the resident male is most agressive toward... seems to be having difficulty with the white sides... probably another male on the way.

And Pauline mentioned to me that the Bluetits are busy at one of the holes in the barn wall....

And that afternoon [at 4:10PM]... we had a flight of Cranes over... they used a thermal from the big steel-clad sheds at Grandmont to gain more height.

Circling in the thermal
 They must have been quite tired... this lot were hardly 'grue'ing at all. The wind had been from the North East all day... the were coming from the South West.... headwind all the way.

Visitors sniping at Winter's chill

An icy cold, misty grey morning yesterday to welcome in February... and a flash of white passed across the walnut tree trunk. I followed it with my eyes and saw a Hen Harrier [Circus cyaneus] Busard Saint-Martin.

Not the one I saw... my brother captured this today [3 Feb 12]


Recognisable, in the grey, only by its flight and the black tips of its wings as it coursed low over the fields towards the Moulin de Cheverny. A nice start to the day which brightened considerably as the sun burnt through the mist.

Song Thrush on the ivy this morning... the ivy berries [an important winter food source] are the black 'seeds'.
A Song Thrush gets chased off the ivy by a Blackbird by a rear assault [beak up backside]... "My ivy berries, you!" scolded the blackbird as it sat on them calling. Dunnocks, Robins and Wrens hurtling all over the place looking for insects, although the Robins have taken to feeding from the seed feeder here. Five pheasants clustered under the sunflower seed feeder in the field gleaning what the Greenfinches, hogging the field feeder, have scattered or wasted. Mr Creosote and his chums [Goldfinches] scattering seed from the seed feeder.... a Green Groundpecker* [Picus viridis] Pic vert working over the potager whilst it still could.
[*That should read Woodpecker... but for a bird that feeds mainly on grubs and ants from the ground perhaps Groundpecker would be better... it's like the Chocolated-headed Land Gull!]

What was that?...
I'm outa here!!

A trio of Willowchiffs [collective name for Willow Warbler/Chiffchaffs when you can't hear them singing] worked their way through the battered celery plants in the potager. All in all, awful lot of bird activity as they fought to keep up their food reserves in this cold, icy weather. But I had work to do... can't spend the whole day birdwatching.

A glance out of the window as a Blue Tit risks a direct flight of the one hundred metre open ground between the trees along the bank of the river Aigronne and the seed feeder here in the cherry tree... it flew low, to avoid the attention of predators... especially the local Sparrowhawk [which I saw burst like a rocket through  the top of the cherry a couple of days ago.] As he passed over the bief edge, I saw movement down by the water's edge... aha! The Water Rail; haven't seen him for a few days, thought I... but wait, that colouring seems wrong... look again.

A Snipe [Gallinago gallinago] Bécassine des marais was preening itself just opposite the kitchen window.
Then it went hunting for food. It looks for soft accessible organic soil, rich in food organisms just below surface. It also requires clumps or patches of vegetation/shrub as cover. Both of which it has aplenty along the bank of the bief.

The warming of the beak!
Warmer now... let's carry on...
It is not a common bird in France [Concise Birds of the Western Palearctic give the distribution in France as 300-350 breeding pairs; listed as decreasing - 2002] - we are towards the southern end of the range here, but it is believed to breed in the Brenne, where it would nest in a shallow scrape, concealed in short vegetation.

A-probing we shall go...

The winter distribution is as far away as the Nile valley and North Africa, but it is shown as a resident breeding species in the Loire valley.  So we are more likely to see them in the winter months. I thought I'd heard 'drumming' round here before, but had dismissed it as such... but pairing and display may well take place as they migrate to breeding grounds and we now know they feed around here in Winter.

Blending in well with the vegetation
He then went up on the bank to pose!

And he's there again now as I started to write this this morning, probing away at the mud along the edge... I wonder how often we've missed seeing them.
