Capital Wildlife - 24 hours in London


We spent a night in London after the launch of the Stanley Spencer anthology at Cookham Festival last Friday. We really enjoyed the atmosphere of Camden Lock, with its barges coming and going. 

At one point there was a bit of a splash as this Cormorant touched down. It was a good reminder that London boasts so much more wildlife than the proverbial pigeons, which admittedly were certainly showing in good numbers. 


Two Canada Geese swam round the corner towards us while we were watching the barges.

At this point we caught a bus to the Tower, renowned for its ravens, which on this occasion we failed to see.


We joined the queue for the Thames Clipper, and I was interested to note how much wildlife had been crammed onto this board... I expect some of the species live further up river, near the mouth. I'm sure we all associate the Thames with eels, but photos of the seahorse and water vole caught my eye.


We had to wait for a while, but it was not too long before we were heading upstream to Greenwich...


...where we enjoyed a rather damp picnic lunch beside the Cutty Sark.

Suffolk Wildlife Trust's Knettishall Heath Reserve



Having left Thetford behind us (please see previous post), we headed for the wild expanse of Knettishall Heath, which is in the care of Suffolk Wildlife Trust. It is the Trust's largest reserve, and even on a dry Bank Holiday afternoon, we saw very few other people once we left the main car park. We decided to start out on the red rabbit trail...


We passed areas of deciduous trees...



... and areas where there were mainly conifers.


On a cloudy afternoon, a few patches of blue sky were particularly welcome.


There were corrugated iron sheets for reptiles. I wonder who was lurking under this one. Adders are occasionally seen, and there are Grass Snakes, Common Lizards and Slow Worms in the area. We shall have to return on a sunnier day...


This Breckland heath is an ancient landscape: the photos above and below show the bowl barrow tumulus at Hut Hill.


It was too cool for most insects, but there were occasional sheltered spots in dappled sunshine...


... and we noticed this Green-veined White butterfly in just such a spot.


When I was scanning the leaves for ladybirds through my zoom lens, I noticed the creature above (and below). I think it may well be a day-flying Fairy Moth (aka a Green Longhorn).


And yes...


... there was a single ladybird. I am not sure whether it is a Cream-spot or an Orange. The three spots on the wing shown on the right (straddling the top of the elytra) in the photo below could suggest the former, but I have a hunch there is more to it than that! I have yet to log the sighting on the UK Ladybird Survey via iRecord, so watch this space. The ladybird flew up in the air then came back and perched on the leaf.




There is plenty more for us to explore on Knettishall Heath on a future occasion, but by 4 o'clock we felt in need of a cup of tea so we drove to the garden centre at Bressingham. There was plenty of steam in the adjacent gardens.

Wildlife in the Ruins (or a grey Bank Holiday in the Thetford Area)


We had been waiting for some time for the 'right kind of day' on which to revisit the Thetford area. Bank Holiday Monday proved just such a day, with short sunny intervals, even shorter showers and a good deal of fair, if grey, weather.

Our first stop was the site of the Priory, founded 1103 or 4, and belonging to the Cluniac order of monks. The remains are in the care of English Heritage. We made our way to the magnificent Gate House, which dates from the 14th century, and were met by the three avian residents you can see in the photo above. I have been trying to ascertain whether the 'white pigeons' are simply that - white pigeons - or whether, perhaps, they are fantails. According to this thread on the RSPB site, they are descendants of the Rock Dove. Feral pigeons are descendants of what has long been known as the Rock Dove. Does this fact make these white pigeons 'feral' doves? I am not sure. But wait, there is an issue with the name 'Rock Dove': do take a look here in the pigeon and dove section of the IOC World Bird List site. 


Above: the pigeons in situ.

The magnificent flint-faced Gate House



 A close-up of the flint, and you can see where strands of ivy have been removed (or in this case, left). Thetford is not far from Grimes Graves, and is a good location for flint.



You can see that we were under rather a dark cloud at this point, but this photo gives a good impression of the extensive remains of the Priory.


You can read more about the Howard family here.
 



The photo above shows the Priory end of the site and the one below is from the spacious prior's lodging.


I went inside the walls of the prior's residence and noticed a corner of wildflowers growing out of the wall. I don't know whether this suggests that this corner is a damp one or whether, perhaps, it is a favourite haunt of wild birds who deposit seeds.


In any case, I was soon aware that there were two bright Blackbird eyes...


... staring down at me. The bird's bill was stuffed full of insects. I left him to his prize catch, not knowing whether male Blackbirds feed the female while she is nesting, though I never saw or heard a hint of another bird in this area. [After note: I have now been able to look up the habits of breeding Blackbirds, and it appears that while only the female sits on the nest, her mate will assist with food finding. Of course, I have no idea whether this particular bird was feeding himself or a family...].

By this time it was 1 o'clock, so we moved on to the next site - which was half a mile away, if that. The ruined Church of the Holy Sepulchre in Thetford is currently undergoing some restoration, as you can see from the photo below. The nave dates from the 12th century, and at some point after the nearby priory (see above) was dissolved in 1536, this particular church fell into use as a barn. I have only found three other UK churches with this dedication or foundation, including the Round Church in Cambridge.



According to the English heritage board, the rounded structure below is an added 19th century grotto, built as part of an ornamental garden feature. How unusual. You can read more about the church here on the Historic England site.


I looked about on the ground and noticed an empty snail shell. There was only one, so the adjacent flints may not have been in use as a regular anvil for a Song Thrush, but they would have served a useful purpose on this occasion at any rate. 


We were being watched from above, and it is possible that this bird had dropped the snail from a height. Song thrushes bang away at their 'anvils' on the ground whereas Carrion Crows and some other corvids prefer to drop a mollusc shell from a height.


It was time for a picnic lunch so we drove a few miles out of town on to the heath in the heart of the Brecks. The soil is sandy here and ideal for the families that were using the bike trails through the adjoining forest.



David and I found several caches of overwintering ladybirds, sadly all Harlequins. I shall add these to the UK Ladybird survey. But to end this section on a happier note, I am pleased to report that both my recent North Norfolk ladybird IDs have been assessed on iRecord and confirmed. One of the species was a (small) Kidney-spot and the other a (large) Eyed Ladybird - both UK species.

We moved on to Knettishall Heath after our picnic, a wildife area in the care of the Suffolk Wldlife Trust. This will be the focus of my next post, and it will include - you guessed - the sighting of another UK ladybird species.

RSPB Garden, Flatford - Insects Emerging


We paid a short visit to the RSPB Wildlife Garden in Flatford, home of the artist John Constable.



It was not particularly sunny, and there was a breeze about, but we managed to spot a few insects.



The photo above shows a corner of the dedicated Wildlife Garden, and the photo below shows the scene from the bridge above the Stour, including Bridge Cottage, in the care of the National Trust.


One of the volunteers in the garden helped us to see an Orange Tip egg, which you can just make out as a golden yellow dot on this stem of Jack-by-the-Hedge (aka Garlic Mustard).


You can see a close-up Orange tip butterfly egg here.


I saw one adult Orange tip, but failed to photograph it.


We noticed a couple of Peacocks in a sheltered spot.


I believe the creature above is some kind of parasitoid Wasp.


I was admiring the rosemary when I noticed this Rosemary Beetle. What a fine-looking insect, but what a pest (do check your lavender, rosemary and sage: you can report your own sightings here). We came home to find one of these beetles on our lavender bush...


There was a Queen wasp (something like Vespula germanica?) on the wooden planks.

Despite one or two less welcome visitors, it was a joy to see the emergence of a variety of insects.
