9/3/11: Two men in a boat

Spent most of the day in a small boat with Eric, 'fishing' for rubbish in the River Cray that could not be safely reached from the bank. It was a small, very stable, but rather 'square' and hard to manouevre craft, so it took us a long time to row slowly from the Riverkeeper's Yard down to the main work site at the old Vitbe Mill Pond, then all the way back again several hours later. There is so little clearance under the Maiden Lane and Thames Road bridges that we had to lie down in the boat and propel ourselves by hand, pushing against the underside of the bridge decks - putting me in mind of the way narrowboat men 'walked' their vessels through narrow canal tunnels.

At the Mill Pond the river splits in two, one branch has a boom across it, and this is where much rubbish and woody debris had accumulated, the other drops over a high weir, with both parts merging into Crayford Creek a little further downstream. It was slow-going work and a total of nearly 20 sacks of rubbish and several large items were removed. There was the usual array of metal drinks cans, glass and plastic bottles. Also lots of small fragments of polystyrene - which were a real pain to pick out of the reeds. This stuff should be banned! The most exotic items were a couple of loo seats, which we were able to get out. Further upriver we noticed a lawnmower on the bottom, which will have to be tackled another day.


On the way down to the river 9 Redwing were seen on Perry St Farm. At Thames Road Wetland a Chiffchaff was calling from somewhere within the Reedmace stands in the morning and 6 Goldfinch were on shrubs on the Sewer Pipe Embankment. At dusk there were a couple of bursts of loudish, scratchy song, which may have been a Cetti's Warbler. A local bird-watcher reported 3 from Crayford Marshes today, and I saw a dark brown bird with a strongly-cocked tail on TRW just before dusk last week.


There was a single Grey Wagtail at the Vitbe Mill Pond. On the surrounding banks were a Pyracantha and a couple of Mahonia aquifolium, none or all of which might conceivably have been self-sown. There was also a modestly-sized Gooseberry plant hard up against the Thames Rd bridge abutment.


On the long row back to the yard a couple of Pike were seen partly out of the water, spawning up against reeds, on By-way 105, and a Song Thrush was singing on the former Samas-Roneo site behind Barnes Cray Rd.

21/2/2011: Northumberland (Heath ....) / Erith - golden Gorse and booming bird

There was a Common Gull on North Heath Recreation Ground.

In Erith Cemetery (east side) were circa 40 Redwing making quite a lot of noise, but being quite skittish, 5 Chaffinch, 2 Greenfinch, 2 Magpie, 2 Blue Tit, 1 Great Tit, Blackbird and lots of Wood Pigeon. There were about 70 Starlings in Poplars between the cemetery and Carlton Rd.

I went a little further up Brook Street to Hollyhill Open Space, first because I could hear a Song Thrush there, and second, because I wanted to check whether the Gorse were wild single-flowered plants, or the double-flowered cultivar which I'd previously found the ones by Gravel Hill at Hall Place North to be.

The Song Thrush was singing from a copse at the foot of Hollyhill, but I couldn't get a visual on it. The song was echo-ing within the valley, making it sound very loud indeed, and even more difficult to get a precise fix on the bird's location. There's a good chance it was the same individual heard singing from the Brook Street allotment site recently.

The Gorse, in a stony, apparently weeded 'shrub bed' was all single-flowered, and had recovered from the burning a couple of years ago. At this time of year the way huge numbers of Common Stork's-bill carpet the ground really stands out, and I was able to spot some of the Bird's-foot (Ornithopus perpusillus), which I knew was also listed as being present on the site. Both the latter species are classed as 'notable' for London.

The site as a whole is decribed as 'former heathland' in the 2004 draft 'Sites of Importance for Nature Conservation in Bexley', which raises questions and possibilities in respect of the Council's existing and re-written Heathland Biodiversity Action Plan. This talks about increasing the amount of heathland in the Borough, but in immediate practical terms, or any site-specific prescription for future action, fails to look beyond extending that within Lesnes Abbey Wood.

Looking east-south-east over the Gorse bed at Hollyhill Open Space, across the land-filled and re-greened Erith Quarry site to the right beyond the houses. There's a glimpse of the River Thames in the distance, just left of centre, whilst the church spire in the centre of the picture is that of Christ Church, Erith.

16/2/11: First 'local' Song Thrush in years ....

There was a Dunnock and a Collared Dove in my Barnehurst garden today.

A Brown Rat was seen in Bursted Wood.

Along Streamway (Northumberland Heath/Erith), leading to Brook Street, a Song Thrush was heard, calling from trees between the allotment site and the Erith Cemetery west side, the first I've heard anywhere in this area for ages.

Birds seen along this valley, with its stream, small amount of woodland, grass, Willow and Alder were 1 Redwing, 6 Ring-necked Parakeet, 5 Blue Tit, 1 Great Tit, several Wood Pigeon, 7 Starlings, a Blackbird, Robin and circa 11 House Sparrows in various hedging.

There was some Viola odorata in the wooded section opposite the houses, but this was probably a garden escape. Some Lesser Celandine was noticed here also.

8/2/11: Chasing Waxwings round the Emirates

I was at a meeting in our new Green Party HQ off Old St/City Rd today, so I followed up reports of Waxwing outside Arsenal Football Club's Emirates stadium, and I got to see 5 in Drayton Park road before they took off for somewhere else. That's my third lot this winter. Of course this had to be the day a bunch were also reported from Bourne Rd in my home Borough of Bexley .......

The Waxwings were just over the road from Islington's Gillespie Park Nature Reserve, which I'd never been to before, so I had a look round. There was a Song Thrush singing on the other side of the railway line as the light began to fade.

Earlier in the day I'd wandered round Bunhill Fields burial ground on City Road, and found a colony of Claytonia perfoliata (called Miner's' Lettuce and various other vernacular names), a non-native species I've not seen before, though I soon discovered that its presence here has been previously recorded.

26/1/11: Highgate Siskins steal show

Up to north London today to help the Green Party Office move from Archway down to the Old Street area, and had decided a couple of days ago to take the opportunity to have a last look (for a while anyway) around Waterlow Park in Highgate. Co-incidentally, a report appeared on the London Bird Club wiki that Siskins and Bullfinches had been seen there yesterday.

I got off the Northern Line at Tufnell Park and walked up Dartmouth Park Hill, stopping off at Dartmouth Park (Upper Holloway) part way up. A Mistle Thrush was showing well near the main road and 4 Blue Tit and a Great Tit were in trees. The view over central London from the slope on the east side of the park is as good as from Parliament Hill, and since my last visit the Shard at London Bridge has appeared on the horizon.

In Waterlow Park the first stand-out was a prominent Song Thrush singing with great gusto. A lone Long-tailed Tit was foraging nearby, and later 2 Great Tit and several Blue Tit were seen. Blackbird, Robin, Carrion Crow, Magpies, several Wood Pigeon and several Feral Pigeon were also noted. On the two larger lakes were a total of 8 Tufted Duck, 5 Moorhen, 3 Coot, 27 Mallard and 18 Black-headed Gull.

The best was pretty much last, with excellent and very close views of circa 15 Siskins feeding on Alder cones in the Upper Pond Nature Area at around 11.45 a.m.

Later a Pied Wagtail was seen on an office building in Leonard St., Shoreditch.

9/6/10: Lovely Legumes congregate on Crayford Rough

On my first visit to this site (22/5/10) I had garnered my first ever record of the Yellow Vetchling (Lathyrus aphaca) - though didn't mention it in that post. I knew straight away what this highly distinctive and uncommon plant was from illustrations in books, having been keen to see it for some time.

Today the Yellow Vetchling was in flower, along with an array of other Legumes - fabulous stands of Tufted Vetch of superb colour, Meadow Vetching, Bird's-foot Trefoil, Lesser Trefoil, White Clover, Red Clover and Hairy Tare - and a worthy subject to top this Crayford Rough picture parade.

A clump of Asparagus was a further record for the site.

Insects today included:
- a Latticed Heath moth
- the attractive little Burnet Companion moth, my first ever recording/identification of this species
- a male Banded Demoiselle away from the water
- a male Common Blue butterfly
- a Green-veined White butterfly

Birds noted were:
- a Grey Wagtail
- a male Whitethroat
- a Song Thrush
