Birds, fungi, trees, and Linnaeus


This is a video about a carnivorous plants exhibition in the botanical garden.

Today in the botanical garden. It is sunny, about eight degrees centigrade.

The autumn weather this year has been much warmer than usually, with all sorts of effects on the living world.

There is unseasonable flowering.

Many plants who by the this time of the year should have dropped their leaves still have green leaves.

Including clematis.

And woodbine and sycamore maple.

In the inner city of Leiden, 54 bird species have been observed, most of them in the botanical garden.

Not all of them: a little auk was seen wintering in a canal; so not in the garden.

One of the most frequent species, the starling, can make many different sounds, including edible frogs.

The great spotted woodpecker nests in the garden.

We saw one, in the same tree as a jay.

The ring-necked parakeet also nests here. Sometimes in abandoned woodpecker’s holes; these parakeets are not really aggressive, they don’t drive other birds away.

The tawny owl used to nest in the botanical garden.

It has recently moved to a private garden nearby, but still visits often.

More on owls: here.

Other bird species here: nuthatch; and treecreeper (especially close to the astronomical observsatory buildings).

And blue tits, and long-tailed tits.

About thirty grebes nest in the city canals.

Sometimes, especially in winter, one can see kingfishers there.

On a branch, the fungus Polyporus brumalis.

A bit further, coral spot mushrooms.

And field blewits.

Still further: Psilocybe fascicularis.

Near the exit (also the entrance): Lepista nuda and Lepista inversa.

Linnaeus did not like fungi much, as they were a problem where to put in his system of nature.

Next year, the garden will celebrate Linnaeus’ birth three hundred years ago.

There are two portraits of Linnaeus in two museums of the city.

In the big pond of the garden are spinycheeck crayfish, originally from North America.

In spring this year, when unusual snow prevented them from migrating further east to their eastern Netherlands nesting grounds, 35 hawfinches were here.

On 30 March 1995, Hans Adema had seen just one hawfinch while visiting the garden; which he then described as really special in Daucalium, 1995 #1, page 13.

Hawfinch video: here.

We see a redwing high up in a tree.

Sometimes, goldcrests winter in the garden.

Concerning sparrows, we should watch whether they are the most frequent species, the house sparrow; or tree sparrows; or Spanish sparrows, very recent arrivals in The Netherlands.

Crocus laevigatus flowers.

In Britain, crocus species flowering in autumn are well known.

In The Netherlands, crocus species are associated with spring, so the autumn flowering ones are less known.

A young grey heron, just before the exit.

Linnaeus, Catesby and “Carolina” in birds’ scientific names: here.

    Mood: Looking Playing: Beautiful Bird, by Travis

    At the same spot between the yellow pond-lilies where I saw one great crested grebe resting a few days ago, this time two grebes were resting.

    This was the first time ever the botanical gardens celebrated the summer solstice.

    At the Victoria amazonica hothouse, a bright pink flower was in bloom. Babies were put on the giant leaves by a lady in big wellington boots wading through the pond.

    At least four butterflies fluttered through the hothouse. Two species live there: the small Bicyclus anynana from Malawi, and a bigger one.

    In another hothouse, Nepenthes (insect eating flowers from South East Asia).

    Outside, I found a great spotted woodpecker’s feather. A bit later, I heard that species call.

    The tadpoles and pondskaters were still in the stream. At the big pond, later, an edible frogs’ chorus.

    You can also buy plants from the botanical gardens. Prices range from 2000 euro for a Victoria amazonica, to 250 euro for a Cedrus libani (Lebanese cedar), and 100 euro for an Ulex europaeus (gorse).

    For me, 2006 started with the sound of a great spotted woodpecker.

    It often starts its springtime drumming sound, using tree branches, already in winter.

    However, this is the earliest I ever heard it.

    Yesterday, my last 2005 visit to the nature reserve.

    Blue tits in the trees.

    Egyptian geese in the meadow.

    3/5/06 Animals: Greenfinches. No more hawfinches? No more snowman

    Today again in the botanical garden. Water much less frozen than yesterday. The canal around the city centre open water again. Most of the brook ice free. A wren sits again in a bush next to the brook. The ponds at both ends of the brook are also open water again. In the lower pond, I could see the gold coloured backs of carp, swimming slowly under water. On the water, a couple of mallards;> 0

    3/4/06 Animals: Hawfinches, greenfinches, and budgerigars

    Today again in the botanical garden. Open again, after closure on Saturday. Water still frozen. Including the lower pond, where the ice is opaque so you can’t see carp swimming now. Snow has mostly melted away. Sleet. Crocus and daisies and snowdrops flowering. The migrating hawfinches are still there. First I hear from others they have seen them. Then I see them myself. There are greenfinc> 0

    Today again in the botanical garden. Water more frozen than yesterday. Including the canal around the city centre. Most of the brook. A wren sits in a bush next to the brook. The ponds at both ends of the brook are also frozen. In the lower pond, beneath the still relatively thin layer of ice, I could see the gold coloured backs of carp, swimming slowly. Snow everywhere.

    3/1/06 Animals: Hawfinches and greenfinches still in the garden

    Today again in the botanical garden. Water still partly frozen. Snow everywhere. Crocus and snowdrops flowering. The migrating hawfinches are still there. Sometimes, they hide near the big trunks of coniferous trees. There are greenfinches as well. And jays and magpies. And a herring gull. 0

    2/28/06 Animals: Hawfiches, greenfinches among ice and snow

    Today in the botanical garden. Water partly frozen. Snow everywhere. Crocus flowering. The wintery conditions mean that migrating hawfinches are not going further north now. So, unique for this region, a group of these usually shy birds, here in the garden. As I enter, I see ten hawfinches in a tree near the rose garden. Others saw fifteen today, or thirty on previous days. Later the birds g
