Plant galls on Pendent Silver-lime

I have produced a short, simple paper of observations on plant galls found on Pendent Silver-lime (Tilia tomentosa ‘Petiolaris’ or Tilia petiolaris). I wanted to share a link with forums online where I have discussed anomalies between specimens I have found and the examples given by the main authorities on this topic.

This paper is unlikely to be of interest to those uninterested in Plant Galls. For those who wish to read more, please click the following link:

July 2018: review

I have decided to try and complete a short monthly review of my birding activities on and off the Patch. Here is my first attempt for last month: July 2018.

Patch

Summary: I made five Patch visits in July 2018 and recorded a total of 61 species of bird, two of which were new for the year (Mediterranean Gull and Common Tern). There was a record-breaking heat-wave through much of July and every visit was made in hot weather. On the 15 July Wanstead Flats suffered the largest grassfire in London’s recorded history causing extensive damage to the SSSI and Broomfields.

Highlights were:

  • The returning large numbers of Black-headed Gulls, with over 100 birds (and many young juveniles) seen on the Western Flats on 7 July.
  • A juvenile Mediterranean Gull with the Black-headed Gull flock on the Western Flats on 7 July.
  • Tufted Duck bred successfully on Jubilee with 8 ducklings seen with adult female on 7 July.  
  • Finding two Little Grebe chicks on Alexandra Lake on 28 July (still present as of 19 August).
  • An unseasonal record of 5 Lapwing circling over SSSI and Western Flats on 8 July.
  • My first and, so far, only sighting for the year of Common Tern flying East over Shoulder of Mutton pond.
  • It was a relatively successful July for woodland birds with multiple sightings of Coal Tit and Nuthatch and a single sighting of Treecreeper in Bush Wood.
  • Seeing Skylark, Meadow Pipit, and Lesser Whitethroat (with juveniles) after the fire.
  • A single Red Kite seen over Bush Wood on 21 July.
  • This was a record-breaking month for Little Egret. I counted 14 on 21 July with most on the Ornamentals, but this was surpassed a few days later by Bob with 39 across the Patch!
  • Non-birding highlights were my first White-letter Hairstreak on the Patch (by Heronry on 7 July), and an Elephant Hawk Moth found in the long grass between the Brooms and Long Wood.

Lowlights were:

  • The Great Fire of Wanstead Flats.
  • Missing out on Clouded Yellow and Marbled White.
  • Not seeing any Buzzard in July.

Highlights from ‘elsewhere’

  • Finding my first Yellow-legged Gull (juv) for the year at Beckton Sewage Works.
  • Finding two Mediterranean Gull by the Thames Barrier.
  • Seeing Marsh Sandpiper at Rainham Marshes on 28 July.
  • Also successfully twitching the Red-necked Phalarope at Oare Marshes on 28 July with other good birds including Little Stint, Curlew Sandpiper and at least nine other species of wader.

The month in five pictures…

A late evening twitch: Stone-Curlew

I woke up last Sunday morning intending to right a wrong. Sadly I don’t mean combating a great global injustice. I simply wanted to add a bird to my UK life list.

A Stone-Curlew had been present at RSPB Bowers Marsh at the top of Canvey Island in Essex, about 22 miles due East of my house. But there was no news on the bird sites or social media, so I stayed locally and saw the sub-adult Yellow-legged Gull amongst other things. It was only much later in the day that late news dripped through that the Stone-Curlew was still present. And so I headed out for the 45 minute drive in the evening, somewhat racing against the fading light.

The reserve is accessible 24/7 although the car park was closed. I had the words of a well-known birder ringing in my ears:

When I arrived, the small lane was littered with literally hundreds of the tiny nitrous oxide (laughing gas) canisters and a couple of cars were parked up as people conducted a car sale (I didn’t stop to ask them why they needed to be doing that down a deserted lane). I started the walk not knowing how far it would be until the Stone-Curlew would be visible. In fact, I had no idea where the bird might be as I had never visited the reserve before. The closest thing I had to directions were a tweet from someone saying the bird was visible from the ‘two benches’ area.

The empty car park was not quite empty as a father taught his young son how to ride a mini-motorbike. I walked on.

I stopped briefly at the slightly sorry-looking reserve noticeboard and map which confirmed that the reserve was big. super! I walked on.

The skies opened up and were huge with a few Swift still circling (all of our local ones seem to have long-gone) and a few Swallow trickled through. I walked on.

Sign-posts pointed to different bits of the reserve in different directions with mile+ distances attached. I was running out of time and needed some ‘gen’ or some luck quickly. I walked on.

Most of the wetland parts of the reserve were obscured/protected by high hedges. I walked on.

I saw some people in the distance: a chance for local knowledge/help. I walked on.

They turned out to be a couple out for an evening hack on horses. I asked them if they had seen any birders, to which they replied that they had, but some time ago and some distance away. Oh! Thanks. I walked on.

The light seemed to bleed out of the sky faster than ever. I walked on.

IMG_5621v2

The wind-pumps add to the sense of desolation and slightly foreign feel of the bleak landscape – it felt more like the US Midwest than Essex. I walked on.

IMG_8587v2

Bowers Marsh, Essex (not Kansas)

And then I stopped.

There were two benches, diagonally opposed and overlooking the water stretching out back towards the car park from whence I had come. I set my ‘scope up tall and stood on one of the benches to get the best possible view. I scanned the parts of the wetland and grassland that looked most promising  for the Stone Curlew, and just as the light was getting so gloomy that it was beginning to get silly, a distant bird scuttled into the view of my scope. My first Stone-Curlew in the UK. Another rather embarrassing gap filled on a list.

 

It was an odd sight. Not the bird, although Stone-Curlew is a strange large-eyed bird, of course, but me in the landscape. A man stood on a bench looking through a telescope at a distant bird on a vast reserve all alone apart from the midges and the weather. I strained the technical capabilities of my iPhone to photograph the Stone-Curlew through my scope.

IMG_2976v2

Eurasian Stone-Curlew (Burhinus oedicnemus)

The output was rubbish, of course, but it just about counts as a record shot of a bird I last saw when I spooked a running gaggle (I don’t know what the collective noun is for Stone Curlew) from the hiding place in a parched field in a remote part of Ibiza. The remoteness was even more intense in Essex, but the landscapes could hardly be more different.

As I watched the Stone-Curlew a tiny Yellow Wagtail pottered past in front of it. I was also pleased to see a Black-necked Grebe (possibly two as one disappeared around a corner and another materialised somewhere else suspiciously far away) in mid-moult. I am not sure these birds had been recorded at the site on that weekend by others so a reasonably nice find, perhaps. I photographed the bird in the murky light and remembered the last time had been watching these birds, in full black and gold breeding uniform, like science fiction fascists, in Japan.

Now you see me, now you don’t

One of the great things about birding the same patch is you get to build up a sense (or even a monitored trend for those of us who keep spreadsheets) for which birds you see over time. Migration is, of course, a major factor in birds appearing and then disappearing. Our Swift flocks have now gone. They were present on every visit to the Patch from 22 April until the end of July. I missed last weekend as was away so can’t pinpoint their departure. But it never ceases to amaze me how fleeting their breeding stopovers seem to be. One day the the sky seems full of scything screamers and then, like Keyser Söze, they are gone.

Willow Warbler is a species which seems to have a tentative perch-hold on the Patch. I got four records of Willow Warbler in the Spring. The first was probably just a passage pass-through, and then three weekends in a row in April/May when I had one or two birds singing. Almost certainly an attempt at making a viable territory, but not, perhaps, successful. Now we get a second bite at the cherry with the returning birds and I got a bright bird yesterday in Wanstead Park.

IMG_4809v2

Willow Warbler (Phylloscopus trochilus)

But with other birds, their presence or otherwise seems more arbitrary or subject to annual cycles not connected to migration. It has been a good year for Little Owl on Wanstead Flats. We think two pairs have bred successfully. I looked in their ‘usual places’ yesterday but couldn’t find them, only to hear one calling loudly from a different copse as a dog walker went past it. It stayed put long enough for me to take its picture.

IMG_4862v2

Little Owl (Athene noctua)

Nuthatch, and even Treecreeper, have also been spotted more frequently this year than in others. But other birds seem not to be doing as well. I’ve seen very few Grey Wagtail this year, for example. Whilst Little Grebe seem to be doing better than I remember before, and have bred on Alexandra Lake, Great Crested Grebe have seemed almost entirely absent; I saw my first for this Spring and Summer on the Shoulder-of-Mutton pond in Wanstead Park on Saturday.

IMG_2859v2

Alexandra Lake, Wanstead Flats

2016 and 2017 were good years for Wigeon on the Patch. We saw up to a patch-record-breaking 61 birds in 2016. But there were very few sightings of this duck early this year with it not even being on my patch year list. So I certainly didn’t expect to see one today on 12 August! But Nick found one, on the River Roding, and I photographed her as she is the earliest returning Wigeon we have a record of on the Patch.

IMG_5096v2

Wigeon (Anas penelope)

Other birds are scarce visitors but you come to expect them at certain points in the year. So it is with Yellow-legged Gull. Today three of us were treated with lovely views of a 4th calendar year bird that Nick actually found yesterday by Alexandra Lake. This was a patch year tick for all of us involved.

IMG_5031v2

4cy Yellow-legged Gull (Larus michahellis)

Meanwhile, other birds never seem far away. It is a rare day on the Patch not to hear the yaffle of a Green Woodpecker, or to see one sail over your head at some point. However, despite them being common, I don’t often get to watch them close-up, so yesterday I was pleased to get close views of two males; an adult and a juvenile by Perch Pond in Wanstead Park. In my slightly sentimental state as an expectant dad, I like to imagine that this was father and son bonding on the Patch. Something I hope to be able to do in due course.

Summer waders

Yesterday a lot of London birders were waiting with anticipation to hear if London’s first Marsh Sandpiper in 34 years was still going to be at Rainham Marshes after it was spotted the evening before. It was. Howard Vaughan kindly opened the reserve two hours early, but by the time the first of us got there a couple of reserve volunteers who had been checking ahead of the crowd informed us that the bird had flown high and south towards the Thames with a couple of Redshank just minutes beforehand.

In pathetic fallacy, the sky seemed to reflect my disappointed mood. Bob and I walked back towards the car via the sea-wall on the off-chance we could pick it up on the Thames shoreline. Luckily we were only side-swiped by the wall of rain and wind that swept across the reserve accompanied by thunder and lightning.

IMG_8701v2

Even the odd ping of Bearded Tit didn’t really lighten my mood. By the time we reached the sea-wall, I was further dismayed when I saw hundreds of godwit and other waders take-off across the river. There was a mini Wanstead birding reunion as Bob, Rob, Tony and I scanned the shore. Some Greenshank took flight and Bob and Tony noticed that one of the four seemed much smaller than the others. Shortly afterwards we heard that the Marsh Sandpiper was back on Aveley Pools – and that it had come in with three Greenshank!

I think I must’ve come close to breaking the trans-reserve racewalking record, encumbered as I was with scope, camera, bins etc, but this time I didn’t miss it. As Jono, who we met there as well, remarked, ‘all’s well that ends well’. William Shakespeare couldn’t have put it better! I was thrilled! Lots of the guys needed Marsh Sandpiper for London. For me, it was a full fat life tick.

Another record shot with Common Sandpiper to the right for size comparison

As I stood and soaked in views of a bird species last seen in London when I was three, I overheard other birders mention that Red-necked Phalarope had been found 50 kilometres down-river at Oare Marshes – one of my favourite south-eastern reserves. I am not really a twitcher, but I had the time, I had tasted success, and I like Oare, so I was soon zipping down the M2. By zipping, I mean at times crawling, and others being diverted through industrial parks, but it was worth it.

IMG_4790v2.jpg

It was obviously wonderful to connect quickly with the Red-necked Phalarope in the record shot below sandwiched between the Mallard and the Black-tailed Godwit and with Dunlin behind. We all know that phalarope are small, but being reminded that they are barely bigger than a Dunlin was more of a surprise than it should have been.

IMG_4760v2

Red-necked Phalarope (Phalaropus lobatus)

IMG_4762v2

Oare delivered more than just the phalarope with five Curlew Sandpiper and five Little Stint probably taking the podium places, but the full cast of waders yesterday included:  Avocet, Little Ringed Plover, Golden Plover, Lapwing, Knot, Dunlin, Curlew Sandpiper, Little Stint, Green Sandpiper, Common Sandpiper, Redshank (I seem to have missed Spotted Redshank, but hear they were showing), Greenshank, Marsh Sandpiper, Black-tailed Godwit, Bar-tailed Godwit, Snipe, Red-necked Phalarope, and Ruff. 18 species of wader, many of which were in summer plumage, is not bad for a summer’s day (and I could probably have picked up one or two more if I had bothered to check the sea shore).

The largest grass fire ever seen in the capital” – BBC News

IMG_1383v2

Last Sunday, 15th July 2018, more than 220 firefighters battled for hours and continued dampening down for days. By my measurements, around 320,000 square metres of the patch has been destroyed, that is over a fifth of the entire area of Wanstead Flats and could house well over 50 football pitches. The sad irony of the football pitch comparison, of course, is that all the football pitches are fine. The mown grass was barely affected. It was the biodiverse areas of grassland, scrub, and woodland which has been devastated.

The background is that we are suffering the worst drought in London’s recorded history. The parched grass was tinder dry and ready to react to a carelessly discarded cigarette, a mishandled disposable barbecue, or the match of a malicious arsonist. We will probably never know.

Yesterday I went out for the first time to see the damage. It was harder to see than I had imagined. My patch has been devastated and that is how I felt too.

IMG_9824v2

The charred remains of non-combustible litter and blackened, skeletal trees stand in an ashen desert. No bird song. No butterflies. Nothing.

IMG_4360v2

There were some small mercies. Whilst the patches of brooms have been almost completely destroyed, some of the grassland just south of this area has survived. I found a single Meadow Pipit song-flighting there, and a couple more chased each other amongst the remaining grass. I also heard a short burst of grounded Skylark song. A small family of Lesser Whitethroat also emerged out of bushes that have been cut back and cauterised by the fire. So hope remains.

If we had lost our Meadow Pipits and Skylarks, we may never have got them back. Only time will tell whether this fire has taken a material toll on their fragile hold of this habitat.

Wanstead Park was welcome relief from the damaged Flats.

IMG_3990v2

Aspen and Purple Loosestrife in the Ornamental Waters

Water levels are low in the drought and several ponds have had water pumped into them to stop them becoming parched dust-bowls. Little Egret have been taking advantage of this and fishing in the shallow waters. Yesterday I counted 14 of them; a joint record with three years ago, although now beaten today by my colleagues who have clocked up 17 across the Patch.

In the Old Sewage works there has been more fire damage. The manure heap by the stables was set alight. But then about 100 metres away there was another, and then another patch of grass blackened to nothing. Probably only around 500 square metres, but suspiciously all separate whilst along the edges of one path. Almost as if someone walked along setting fire to the grass as they went.

IMG_6464v2

A small patch of fire damage by the path and paddock fence in the Old Sewage Works

Apparently some people have had to be told to stop barbecuing next to the fire-damaged parts of the Wanstead Flats. I cannot help draw a comparison and see these ignorant al fresco diners with their disposable bbq next to the blackened husk of a once-lush habitat as a microcosm for humanity and our planet: blissfully continuing with whatever the fuck we want to do as we burn and grind our world into ashes and dust.

Gulling the Thames

Amongst the gulls returning to London from coastal breeding grounds, there have been a few gems recently. Most notably a Bonaparte’s Gull that was seen over several days at Crossness. But there have also been a few returning Yellow-legged Gull as well.

It was mainly this latter bird that I went out looking for this morning, starting with the Thames Barrier park at low tide.

IMG_1804v2

Thames Barrier at low-tide

There were large numbers of Black-headed Gull spread pretty evenly along the exposed shoreline (I suppose they don’t really need to huddle together in this heat). There were maybe high double digits of Lesser Black-backed Gull, low double digits of Herring Gull, and a small handful of Common Gull.

It was soon pretty clear there were no Yellow-legged Gull, so I focused on scanning the small gulls. I got lucky and found an adult Mediterranean Gull, always nice to see in summer plumage with its true black head (unlike the choclatey-coloured hood of the mis-named Black-headed Gull). The Med Gull was quite close in, but by the time I had got my camera out and ready, it must have flown. As I packed up and left, I saw one more juvenile Med Gull way down river in the distance so I took a grainy phone-scope shot for my records (and to inflict on my long-suffering readers).

IMG_8697v2

Juvenile Mediterranean Gull (Larus melanocephalus)

By the time I had driven down the road and walked the rather epicly long path down to Creekmouth, the tide had come in rapidly and there was a much-diminished beach.

IMG_2276v2

Roding entering the Thames at Barking Creekmouth with the flood barrier

I checked the Black-headed Gulls floating around the Roding outflow, but couldn’t pick out any narrow-billed Bonaparte’s candidates, or any more thick-billed Med Gulls, so I turned my attention to the Beckton Sewage Works behind me.

It isn’t easy birding the sewage works but it had good numbers of gulls…

IMG_0649v2

Beckton Sewage Works

That view above is not typical or illustrative of reality. I managed to take it because my iPhone pressed up against the fence is small enough to get a good view, but a more accurate representation of what I was looking at is:

IMG_9735v2

I’m not sure quite why the fencing needs to be so narrow and restrictive

The pools in the photo are quite sizeable, and, at 40,000 square metres (Google Maps has allowed me to measure them), they are a third bigger than Heronry Lake on my local Patch.

Creekmouth and Beckton

I quickly found what I was hoping for on the water as one bird stood out quite well, despite the blurry distortions of peaking through such narrow meshing. It was a fair distance away so I didn’t get any good shots, but at least I had found a Yellow-legged Gull.

IMG_4477v2

Juvenile Yellow-legged Gull (Larus michaellis)

As it swam about in the treatment pools, it helpfully aligned up with a Herring Gull to give a better sense of size and bill thickness.

IMG_4450v2

The morning wasn’t all about gulls, a pair of Peregrine performed for me and another local birder who I bumped into, Linnet and Grey Wagtail danced about on trees and posts respectively, and I got some stunning views of Reed Warbler which popped through the reeds and fencing to watch me walk past.
