Birdsong to herald the Spring!

Common Whitethroat

For the last few days we have rejoice in the sound of birdsong and been relieved that so many of our old friends have made it back from their winter quarters to boost the chorus of our native woodland dunnocks, robins and wrens.

Suddenly the hedges are full of willow warblers in their minor key and the excited, raspy call of sedge warblers who suddenly throw themselves into the air, showing off to the female of his choice. Now the reed warblers join in with their lower, more guarded song. Evolution has taught them to conceal their location and that of their nest. Now they are all singing to attract a mate, all with their own particular refrain.

As you can see, to make things more interesting (with the exception of the reed warbler) they do not usually call from their eponymous habitats!

Everywhere we go we listen for the Cuckoo — this year everywhere we go we hear him. We hear him calling from all around but he flies always behind the trees so we cannot see him. This morning the sun was shinning and at last we saw one, here he is shouting from the highest branch, before taking off to advertise himself to the females on the other side of his large territory.

We heard a female cuckoo’s call back, said to sound like water going down a plug hole, to me it is more like the whinnying of a horse. She calls from cover while she stealthfully searches for the nests of any careless reed warbler or dunnock, who has given away her nest and left it unattended.

Down by the river we notice something swoop down and disappear into a hole — I stake it out with my camera. What is this?

A Blue Tit, nesting in a convenient rusty post.

One species is well ahead in the breeding stakes —

Tawny owl twins meet the world — sitting in the sun this morning.

Cuckoo!

Just after dawn this morning we witnessed something very odd and heartening.

Everyone knows how the wicked cuckoo preys on the poor little birds (reed warblers, dunnocks, meadow pipits), laying an egg in their nests which hatches into a monster that evicts the other natural nestlings and grows huge on the tireless efforts of the adoptive parents.

This morning we heard the first cuckoos, up in the forestry. There were two males vying for territory, skirmishing in the treetops. Here is one.

The two birds had quite distinct calls so we could monitor their conversation! Both had the striped breast that is said to mimic a sparrow hawk — a cunning ploy to frighten the prey hen bird from her nest and give the female cuckoo time to lay.

The little birds out and about today were mainly willow warblers and robins but whichever they were some of them were not afraid of the cuckoos.

In fact groups of little birds were attacking the relatively huge cuckoos and driving them off their perches so… Not just feckless victims!

Heroic little birds.

Happytats for Birds and Bats

In a sheltered dimple on the far bank of our stream, facing south, we have spotted the first three tiny yellow lights that herald the Spring — they are ranunculi, brilliant buttercups with pointed stellar petals — broaches on the tweed of winter.  At this signal the woodpeckers have begun to drum.

It's a struggle to be first

It’s a struggle to be first

There is perfume in the air and overhanging the water, hazel catkins are dancing in gusts of March wind and the sunshine makes long shadows.   Clouds of frogspawn drift across the pond, strangely not reflected in the sky.

There is birdsong and the hum of passing wings.  The female pheasant from last year has reappeared.  Magpies are bickering and squawking in the field and above a circling buzzard mews so I go to check the sheep — a buzzard sees or smells a labouring ewe from high in the sky and will dive and swerve and snatch the precious afterbirth from the squabbling crows — but not today.

They will have to find some other quarry and that has reminded us that it is time to put up the bird boxes and the bat boxes that we made last winter.

?????????????????????????????

Prime real-estate – detached timber homes of French oak (offcuts from the office shelves) and other experienced material (hundred year old doors) deconstructed by a son and now born-again bat boxes with loft-ladder access from below (not shown).

We have sited them all carefully.  For bats: on the flight-path through the wooded glade at different heights for different species and facing for the morning or the evening sun.

The bird boxes face North-East, shaded and protected from the prevailing wind and sited with great thought, and not a little argument, about the specific requirements of the intended tenant whose name is penciled on the side – a test of avian literacy.

Do you think the mouse that was squatting in a bat house while it waited in the barn (avoiding the cat that sleeps on the rick) will find it up the tree?

Never overlook the importance of opportunism and untidyness in habitat creation!
