This video is about a whooper swan family in the Amsterdamse Waterleidingduinen nature reserve in the Netherlands.
Anke Bruin, warden on Vlieland island, reports on rare birds there.
Recently, Ms Sophie van Amstel saw a glossy ibis flying there.
Last week, there was a whooper swan on a meadow. It was alone. Apparently, it had lost its family. Whooper swans usually don’t migrate individually.
Recently, two little crabs beached on Vlieland island in the Netherlands.
They were hairy crabs.
The Netherlands is about the northern limit of their habitat. So, they are rare there.
This is a video from Canada about red knots.
Anke Bruin is warden on Vlieland island, the Netherlands.
She reports on counting birds there last weekend.
People counted 304,000 birds along the coastline of Vlieland. That was more than on many other similar counts; probably, because of the high tide.
The most numerous species were red knots: 64,714.
Then, dunlin: 64.000.
The third spot was for the black-headed gulls.
Less numerous, but remarkable, were Arctic skuas. 25 of them, including a group of eight birds on the Vliehors.
Another rare bird was a red-necked phalarope.
This video from the Netherlands is about map butterflies (their early summer morph).
Recently, map butterflies were recorded for the first time on Ameland and Vlieland islands in the Dutch Wadden Sea.
Probably, south winds blew them to these most northern places where this species was ever seen in the Netherlands.
Since about 1950, map butterflies spread over the Netherlands from the south.
On Monday 8 July, a bee was photographed on Vlieland island in the Netherlands.
That bee was an Anthophora furcata.
This species had never been recorded on Vlieland before; though it is known to live on Texel and Terschelling islands.
About relatives of this species, see here.
This video is called Great Tit (Parus major) singing.
In the 1950s, there were ten nesting great tit couples on Vlieland island in the Netherlands.
In the 1990s, this had risen to about 100 couples.
Now, there are about 250 great tit couples; plus some 65 blue tit couples.
Research has found out that great tits in the west of the island are genetically different from eastern Vlieland birds. An article about this in Nature is here.
Eg, in the west of Vlieland, there are on average 9.5 eggs per nest; in the east, 8.35.

The blog of Anke Bruin, warden on Vlieland island in the Netherlands, reports that more dune pansies than ever are flowering on the dunes of the island this year. This is because sand from the beach was blown into the dunes by winds.
The pansy plants attract caterpillars of various butterfly species, like the Queen of Spain fritillary.
Northern wheatears eat these caterpillars. So, many dune pansies is good news for wheatears.
Northern wheatears nest in rabbit holes. The rabbits keep other plants short, which helps the pansies. The rabbits don’t eat pansies.
Interesting, this interaction between various species.
This video from Britain is called Taking a look at Terns 2: Roseate, Sandwich and Little Tern.
Warden Carl Zuhorn reports that little terns are back nesting on Vlieland island in the Netherlands.
Last year, 68 little tern couples nested on Vlieland. For the first time since many years, some chicks fledged.
Little terns are vulnerable nesting birds. They nest on beaches. That makes the nests vulnerable to high tides, or to people walking on beaches with dogs.
This video is called トゲウオの巣卵ファンニング行動 Freshwater fish Ninespine stickleback fanning his nest.
Translated from ichthyologist Gerbrand Gaaff in the Netherlands:
Schiermonnikoog and Vlieland have a freshwater fish fauna with very few species. Actually only the ninespine stickleback plays a significant role there. In addition, on both islands also Prussian carp (a carp relative) are sometimes caught. The sweet waters of the other three islands are also inhabited by perch, roach, bream, silver bream, common rudd, carp and pike. The zander lives only on Texel and the tench only on Terschelling.
See also the table here.
This site says that the goldfish (domesticated form of the Prussian carp), probably released from aquariums, is the only freshwater fish of Vlieland.
This is a brent geese video from Scotland.
Translated from the blog of Anke Bruin, warden on Vlieland island, the Netherlands:
Brent geese numbers in the Netherlands are at their maximum in spring. That maximum has been about 75,000 birds for some years now.
Here is a list of brent geese counts on Vlieland in 2012.
