Again I was surprised by how near the city centre these rooks were living. The rookery which features below was surrounded by blocks of flats, although it did also overlook the river Spree.
The individual above looking at me quizzically was prospecting for food in the company of a couple of hooded crows, including the subject of the first picture in the previous post.
Two members of the crow family today. Here is the hooded crow, a bird which only turns up in the wild in Britain in Scotland and on the Isle of Man. They look like carrion crows with fancier plumage – indeed the two species can hybridise where their ranges overlap.
On a previous visit to Berlin in the autumn I noticed a fair few of these birds around. But this time, in the middle of winter, they seemed to be everywhere across the city centre.
The guano which sticks to these railings even in rainy Berlin gives some idea how rich the pickings are for gulls on the river Spree.
Not many pictures of local wildlife recently. I’ve been away, and the poor weather doesn’t encourage me outside. Here are some pictures of woodland birds eating at a feeding station in Tiergarten, a large park in central Berlin. The blue tit (above) was tolerant of me standing in the open nearby taking pictures.
So was the nuthatch (below). It is eating a seed it has taken from the feeder, not the bud at the end of the twig.
These tree sparrows would be strictly a countryside bird in Britain.
The erratics featured in the previous post have a rich crop of lichens growing on them: an indication that the air there can’t be very polluted. This is one patch of the lichen on the largest stone.
Three large erratics which have been tidied away to a quiet corner of the car park of the Aldi supermarket now on the site of the former Fighting Cocks pub.
A common mushroom which can appear pretty much any time in the second half of the year. Brown roll rims have a mutually beneficial relationship with many types of trees. The underground section interpenetrates with the roots of the host tree. The fungus uses the tree as an energy source, and in return gives up minerals which it has got by breaking down dead organic matter in the soil.
The funnel shape of the cap is often more pronounced than in these specimens.
Two of the exposed, partially overgrown, rock faces on the former quarry on Barrow Hill, in the LNR of the same name in Pensnett.
The quarry was for a hard rock of volcanic origin, diorite, which is a form of basalt. Dudley Council market Barrow Hill as the “Dudley volcano” (it erupted300-odd million years ago).
Diorite was also quarried just across the borough border in Sandwell, where the Rowley Hills were the source of Rowley Rag.
Like yesterday’s mushroom, these waxcaps have a viscid surface because they are moistened by the melted frost from the previous night. They were growing in the same patch of mossy grass as that mushroom.
The pictures were taken during December’s cold spell, not the current one.
Members of the crow family tend to be sociable birds. These pictures are of about half of a flock of jackdaws. Two members of the flock were also featured eating alongside gulls a couple of days ago.
