Woodpecker, blackbird on balcony

This is a video of a great spotted woodpecker making a drumming sound. Not, like usually, on a tree, but on a TV antenna.

This afternoon, a male great spotted woodpecker.

It was eating the grease on the top of the nest box above the balcony.

Then, it flew to the tree behind the balcony. Then, it flew away.

Soon, two wood pigeons in the tree. On a roof behind the tree, two magpies.

Later, a female blackbird on the balcony, eating seeds from a bowl. While a male blackbird sat in the tree.

In the morning, there had been chaffinches in the tree.

And, of course, many great tits and blue tits at the feeders.

Woodpecker and snow on the balcony

Today, the first snow of winter.

Like usually, great tits and blue tits at the feeders.

Ans a wood-pigeon below them on the balcony.

Also, after we had not seen it for some time, a great spotted woodpecker.

This is a great spotted woodpecker video.

Then, it flew from a feeder to the tree. Then, it flew away.

Woodpecker visits new bird feeder

This is a great spotted woodpecker video.

This morning, again a great spotted woodpecker on the balcony.

Maybe the new long bird feeder which allows woodpeckers to rest their tails comfortably, attracted it. It fed there.

A blackbird came as well. And a wood pigeon.

Also the usual great tits and blue tits.

In a tree opposite the balcony, a chaffinch.

Woodpecker and blackbird back at the balcony

This morning, like yesterday, great tits at the balcony bird feeders.

Chaffinch on the balcony floor.

A blackbird (which we hadn’t seen here for a long time).

And a great spotted woodpecker, only for the second time. This time, it ate fat at the house-shaped feeder.

This is a video about a juvenile great spotted woodpecker, eating peanuts at a feeder. It is still a bit clumsy at it; so, its mother comes to help it.

Great spotted woodpecker on the balcony

This morning, the usual bird species around and on the balcony feeders.

Like blue tits.

Many great tits. Some of them, the radio said, may have come all the way from Russia. There is unusually big great tit migration from eastern Europe to western Europe now.

A wood pigeon. A couple of magpies. A jackdaw.

Then, a first for the balcony. A male great spotted woodpecker!

This video is about an adult great spotted woodpecker feeding its young in a garden.

A bit later, a male chaffinch looks for seeds on the balcony floor. Only the second time that I saw this species here.

Dutch waders photos from Breebaart

On 23 July 2012, I was in the hide of Breebaart nature reserve in the Netherlands.

These wader photos were taken then.

Woodpecker, reed buntings, wren and plants

This August 2018 video is about the Amsterdamse Waterleidingduinen.

18 March 2012.

After we went to the sea through the Amsterdamse Waterleidingduinen nature reserve, we returned.

We pass a bunker in the dunes. During the nazi occupation, it was used by Hitler’s Wehrmacht. Now, by wintering bats.

Dunnock singing, Amsterdamse Waterleidingduinen, 18 March 2012

A bit further, a dunnock singing on the top of a bush.

Near a canal, a pied wagtail.

A magpie on the footpath.

A woodlark singing.

Bluethroat and reed buntings of the Naardermeer

This is a bluethroat video.

12 May 2008, to the Naardermeer nature reserve.

In the marsh on the opposite side of the road: many shelducks; grey lag geese; northern lapwings; mallards; gadwall.

And a female reed bunting.

A bit further in the Naardermeer reserve, grey lag geese and barnacle geese, both with goslings.

Redshanks on the mud.

Pied wagtail.

A male shoveler swimming.

One of many singing male reed buntings of today.

A bit lower in the vegetation, a male bluethroat.

Cuckoo and reed warbler sounds.

From a hide, great egret and female mandarin duck.

We go to the next hide, De Wijde Blik.

Sedge warbler and grasshopper warbler singing.

Egyptian geese and great cormorants.

We walk on. Brimstone butterfly and buzzard flying. A juvenile edible frog in a ditch.

Then, back to the Wijde Blik.

A speckled wood butterfly between the trees.

On the water, coots and male tufted duck.

Mating dragonflies. A fine view of singing reed bunting and sedge warbler.

At the next hide, shelduck and little grebe. A bit further, a roe deer.

Finally, a small tortoiseshell butterfly on a yellow flower.

FEMALE LARK BUNTINGS—medium-sized sparrows that breed throughout the Midwest [in the USA]—show strong preferences for males with certain physical traits: here.

Grey wagtail and gulls

Today, temperature a bit above freezing. There is still ice on small canals, but not on the river.

Tufted ducks diving near the river Rhine. A great cormorant.

On the river bank, and sometimes on a small boat moored there, a grey wagtail. This species is unusual for a city. A grey wagtail photo is here.

Grey wagtail in Tunisia: here.

My feeding of water birds attracts scores of black-headed gulls, one common gull, and a few coots and mallards. Fish-eating great crested grebes keep their distance from the melee.

Noisy grazing sea urchins

This video is called Sea urchin flipping.

From New Scientist:

Grazing sea urchins create reef cacophony

* 16 July 2008

AMPLIFIED chewing sounds from ravenous sea urchins create a dawn and dusk chorus beneath the waves.

The ambient underwater noise on rocky reefs becomes a hundred times louder just before dawn and just after dusk. To find out why, Craig Radford and his colleagues at the University of Auckland, New Zealand, recorded the sounds made by individual reef animals in the lab, and then compared them with the dominant sound in the natural reef din.

Listen to a recording of the sea urchins in the lab.

Unfortunately, that link does not work.

They found that grazing sea urchins produced the noise as they scraped algae off rocks. The hard, dome-shaped bodies of the animals act like resonance chambers, amplifying the sound of their chewing (Marine Ecology Progress Series, vol 362, p 37).
