The busiest burdock

In my last post I wrote about the wildlife to the north of Histon. This post is about the wildlife to the west of the village. The two areas are divided by a main road and they are quite different in character. The north is very open with big open fields lined with ditches and hedgerows and the west has more trees and scrub.

In mid June I ventured there to compare the birdlife with that to the north, because I normally see less farmland birds like skylark, corn bunting and yellowhammer here, but more finches and migrant warblers like chiffchaff, willow warbler and whitethroat.

Dog rose (Rosa canina) bejewelled with raindrops

There had been a refreshing shower shortly before I set out which had left the flowers on a rose bush bejewelled with raindrops. It was a good time of year for the wild flowers as the ground had not dried out and there was plenty of sunshine. And of course, if the wild flowers are in good shape, there’s plenty of food for insects and therefore abundant sustenance for birds too.

(And on the subject of insects there was a news report from the BBC today regarding the short-haired bumblebee (Bombus subterraneus) which became extinct in the UK in 2000, but was reintroduced to an RSPB reserve at Dungeness in Kent and is now successfully breeding. Great news!)

But I digress. The dog rose flower was in the local meadow, but passing through there to the farmland beyond there is a field which is lined with drainage ditches, hedgerows and wide unmown borders which support a wealth of wildlife including wild flowers, bumble bees, dragon flies and birds. One of the wild flowers there is the burdock, Arctium minus, which has enormous spiky leaves and big burs which get stuck to your clothes, and on this walk there was a burdock patch that was full of songbirds:

The linnet (Carduelis cannabina, Dansk: tornirisk) were omnipresent here throughout the summer, and occasionally a yellowhammer (Emberiza citrinella, Dansk: gulspurv) appeared too. It’s easy to find yellowhammers if they’re in residence because of their characteristic song (a-little-bit-of-bread-with-no-cheese).

And the yellowhammer song carries on the wind for hundreds of metres and because they are so colourful they’re easy to spot with a pair of binoculars.

At least one pair of whitethroat (Sylvia communis, Dansk: tornsanger) were nesting on the edge of this field too. The whitethroat are amber listed and the conservation status of the linnet and the yellowhammer is red list due to decline in their numbers. And in a very old oak tree just a few metres from here was a pair of barn owls (Tyto alba, Dansk: slørugle) nesting, and their status is also amber, but more about those in a later post.

The birds and the bees (and the flowers)

As our warmest and driest Spring on record turns into what is shaping up to be a warm and dry Summer, nature’s great events are occurring apace to exploit the prevailing climatic conditions.

The first swifts were seen over Histon 3 weeks ago (by me at least) after their heroic journey back to their breeding sites from overwintering in Africa. To celebrate this event I’ve spent several hours sitting in the garden of the Castle pub on Castle Hill in Cambridge enjoying a few convivial sharpeners and watching the swifts shrieking through the sky like an avian aerobatic team. I can heartily recommend both activities!

Wild flowers, including one of my favourites, white campion, are now in bloom:

White campion is a dioecious plant which means the male and female reproductive machinery are on separate flowers. It grows in well drained earth and flowers from Spring to Autumn and is now delineating my walks across the open countryside. Another one of my favourite wild flowers is red clover (Trifolium pratense) which is a gorgeous colour and provides nourishment for bumble bees:

And of course the local birdlife has been very busy breeding and raising chicks. Alot of species started this process earlier this year due to the unusually warm weather in Spring. I have a pair of blue tits raising a brood in the nestbox in my crab apple tree and my friend told me of a family of song thrushes which fledged from his garden a month ago. Which is very early.

A pair of great tit have been feeding their chicks on crushed peanuts which I put out on my bird feeder over the last month and last week they fledged and the whole family were feeding in my garden for just a day or two before they ventured further afield. (If you put nuts out for the birds during the breeding season please make sure you use crushed nuts as inexperienced parents can try to feed whole nuts to chicks and this can have fatal consequences). Great tits have over 70 different vocalisations which I think is remarkable, almost simple language! And on my explorations along the fields and hedgerows around Histon last weekend (21st May, 2011) I saw more great tit, blackcap and whitethroat all feeding gangs of fledglings:


Common whitethroat male, Sylvia communis

There are two species of whitethroat to be found locally, the common and the lesser (Sylvia curruca). They are distinguished by their song, which I won’t try to describe because I’ve never yet read a book which gives the remotest idea of what birdsong actually sounds like by a written description! But if you want to compare them try here for the common whitethroat, and here for the lesser whitethroat.


And another male whitethroat, this chap was singing long and loud, punctuated with characteristic jerky flights straight up in the air and back to the same spot

There are a good number of common whitethroat in the hedgerows north of Cambridge, lesser whitethroat are also here but are not so numerous. There are other distinguishing features between the two species, the lesser, as the name suggests is smaller (~11cm long compared to ~13 for the common), and is generally more grey with a pale grey head and noticeably darker grey ‘ear’ patches. It also has dark grey legs. Both species overwinter in sub-Saharan Africa, the common in central Africa and the lesser in eastern Africa.

Linnet can be regularly seen flying around the bramble thickets on the edges of the village and perching and singing on top of them. On Saturday early in the morning a fracas was going on in an elderbery tree in Rowleys Meadow in Histon which ended when a jay was chased out of the tree by a family of linnet and a family of whitethroat. The jay alighted on an adjacent shed to suss out the lie of the land and contemplate another raid whilst the indignant songbirds dispersed into some scrub to hide. Eventually the jay decided to keep his powder dry and disappeared into a nearby wood. Jays, like other members of the crow family, will raid nests of smaller birds for eggs and chicks, so it’s a perilous business being a small bird with a family to rear.

Linnet, Carduelis cannabina, are abundant resident and migrant breeders, although their numbers, as with many of our songbirds, are declining, and they are also passage and winter visitors. Due to their declining numbers over the past 40 years or so their conservation status is red, indicating they are globally threatened. They are finches which live in open country and farmland and feed on seeds.

Many species of moths, butterflies, bees, flowers and a plethora of other creatures are all appearing as trhe seasons are progressing and there’s something new to see every week!
