October birding & moths

October has the potential to be the best month of autumn but this year it was pretty quiet in London. Visible migration (vismig) - counting birds flying over on their way to their wintering grounds - is typically at its peak and there were a few decent days but the weather conditions weren't that good locally, although some sites in London seemed to be better placed.

Rainham Marshes

I managed eight visits this month and added one new year bird - Merlin. Although I missed what was presumably the same tame juvenile that hung around Ken Barrett hide earlier in the month, I did see it zoom past Butts hide a bit later. One day I'll get a photo of one.

Water and Rock Pipits returned this month and one of the former was reasonably obliging in front of Butts hide but a bit distant for a decent photo.

Water Pipit

Black-tailed Godwits increased in number during the month and often showed well over high tide when they fed on the reserve. They've all now moulted into their drabber winter colours.

In the second half of the month a female Garganey was found which stayed around a while but could be tricky to track down.

I didn't manage to connect with the two Glossy Ibis that briefly dropped in but there's still a lot in the country so plenty of time left. On Halloween a probable Richard's Pipit was seen on the tip but had long disappeared by the time I arrived.

The final thing of note at Rainham (apart from the welcome re-opening of the Shooting Butts hide) was a Feathered Thorn moth which was roosting on the outside of the visitors centre on 31st.

Beam Parklands

I visited a dozen times this month and the increased coverage paid off on the 26th. I was over at dawn for some vismigging when I heard a distant call in the trees. It sounded like a Yellow-browed Warbler but was just too far away to confirm so I hurried over. Eventually it called again and I was close enough to sound record it. I heard it a few more times but never managed to see it as it remained deep in a dense patch of sallows. They're still a fairly rare bird in London with typically no more than a handful of records each year so it was a nice addition to the site list.

I've had the usual finches on vismig here: Chaffinch, Linnet, Siskin & Redpoll but no Brambling yet.

Dagenham Chase

Nine visits in October, most of which were early morning for vismig. The best bird was a flyover Rock Pipit, the same day that several other sites in London recorded them. They're pretty scarce here with just six previous records, the last being in 2016.

Other sites

I visited a number of other local sites: Parsloes Park, Mardyke OS, Central Park, Goresbrook Park, Barking Riverside, Beam Valley CP and Bretons Park.

Moth trapping

With the nights getting colder, the number of moths flying has drastically reduced and a spell of rainy weather prevented me from running the trap. However, I still managed to add some new species this month.

September birds and moths

In the birding calendar September is in the middle of autumn, most Swifts have left before the month begins and by the end of the month winter birds such as geese begin arriving. The weather has much more of an influence as storms bring in seabirds and easterlies bring in migrants from the continent. This year all that happened in September, and more.

Rainham Marshes

I made ten visits this month including a couple of river-watches when the winds were blowing from the east. They weren't quite strong enough to bring lots of seabirds up the Thames but the 24th was the best. I'd already seen a couple of Sandwich Terns and while I was having lunch and scanning the river I got a phone call to tell me there was a skua on the river. I soon picked it up in flight by the Amazon depot and then it flew across the river and back. I could see it was an Arctic Skua and Dave and Andy also confirmed the ID.

It landed in the middle and spent the next 20 minutes drifting upriver past us and then got up to harass some Herring Gulls before landing again and drifting out of view towards Erith.

Arctic Skua at Rainham

This was my first skua species at Rainham and we'd been talking about skuas earlier so it was a good reward for my efforts. The skua and the tern were both London year ticks.

Waders were still fairly thin on the ground at Rainham apart from Black-tailed Godwits which had increased to a decent sized flock of a couple of hundred but there was no hoped-for Little Stint this month.

Red Kites were regularly seen on the tip and Hobby was present throughout but down to just a singleton in the last week of the month.

Insects have been flying all month with several Clouded Yellows, plenty of Wall Browns and the odd Brown Argus being the most notable.

Dagenham Chase & Beam Valley

I also visited The Chase ten times, mostly trying to catch up with chats/flycatchers. I eventually managed to see an elusive Common Redstart that spent several days hanging around the burnt patch on Fels Field. It was another new bird for the year although I did later hear one at Rainham.

I missed the Whinchats but just about caught up with one of the Stonechats in Fels Field. Otherwise, it's been a quiet autumn at The Chase, not being helped by The Slack being out of action as it dried up in the summer. A few Siskins and Redpolls have flown over, hopefully the vis-mig should pick up in October.

A further eight visits were made to Beam Parklands/Beam Valley CP, some of which were on the way to The Chase. Beam Parklands is still recovering from the large fire in the summer. As yet, I've not found anything of interest at either site this autumn but there's still time.

Brent Reservoir

I've been waiting over two years for a good bird to be found at Brent since I moved and when Ben found a Glossy Ibis - it was Sod's Law that it was during a week long tube strike so I didn't attempt to go on the first day. I did hatch a plan for an alternative route if it stayed another day and with positive news I went the following day.

I took the train from Dagenham Dock to Barking, changed onto the Goblin Line to Gospel Oak and then the North London line to Brondesbury (I really cannot be bothered to learn the new names of the six splits of the Overground). I then got the 32 bus to Staples Corner and cut through East Marsh to the hide, two hours and 20 minutes after leaving home.

After a few minutes searching the ibis suddenly appeared, feeding around Willow Island. I watched it for a while and managed a few distant record shots before leaving for the return journey. As it was a first record for the site, it was also new for my Brent list #211 but I'm going to have to wait a long time at this rate before I can catch up to Leo who's seen the most birds at Brent.

I decided to try a different way home and walked up to Hendon station and luckily just made the Thameslink train which had just arrived. I changed at Farringdon onto the Lizzy line all the way east to Romford where I got a bus home; it ended up being quicker by half an hour. The ibis wasn't seen in the afternoon and presumably went back to the London Wetland Centre where it spent the rest of the month.

Beddington Farmlands

With news of a Grey Phalarope at Beddington, I resorted to TFL's journey planner to plot a route to go on positive news the following morning. So on the 18th I took the tube to Balham via Bank and got a train down to Hackbridge. It was a fairly simple journey considering I was travelling across London. It's just a five minute walk from the station onto the public footpath that runs up the west side of Beddington and a few minutes later I'd reached North Hide.

A couple put me on the Grey Phalarope, it was walking around on the muddy island and was a bit distant but over the course of an hour it eventually came a bit closer.

Grey Phalarope, Beddington Farmlands

It's been a very long time since I've seen any phalarope in London so it was good to catch up with this bird. It had been blown inland by a storm and two more were on Staines Reservoir. I finished the month on 171 species in London on eBird, higher than any of my previous annual totals and with a quarter of the year left, there's still plenty of opportunity to add to this total.

Southend

I made one trip outside of London this month, into deepest, darkest Essex. I met John and Janet at Upminster and we took the train to Southend. After a look around the seafront where I counted 60 Little Egret, probably the most I've seen in the UK. 

We went onto the pier (it opens at 10.15) and walked down to the end. The wind was NE but too light to bring in much in the way of seabirds but we did see a few Gannets and some early Brent Geese flew past, my first of the autumn and probably the earliest I've ever seen them. 

Southend Pier

A couple of Sandwich Terns flew past and several Med Gulls were around the pier. Turnstones lurked around the picnic tables looking for scraps.

I managed to run the trap on most nights during the month, the number of species declined as the temperature went down. As the month progressed, autumn fliers started to emerge.

August Birding

This month typically sees the first 'proper' autumn migration with many warblers on the move along with flycatchers, wagtails & pipits and an increase in waders.

Rainham Marshes

I managed only seven visits this month, fewer than I had expected but a couple of heatwaves put paid to more visits. I'd missed Wood Sandpiper a couple of times already this year and this is the best month to see one so I was pleased to find three on Aug 19th on the newly-named Small Aveley Pool. They hung around for the rest of the month with up to five birds seen.

2 Wood Sands & a Black-tailed Godwit

This pool proved to be a magnet for waders during the second half of August with two Ruff, Green Sandpiper, Little Ringed Plover and a flock of Black-tailed Godwits all present.

Two more year birds were seen, a Whinchat on the tip and a family party of five Spotted Flycatchers at the end of the woodland.

Spotted Flycatcher

The 19th ended up being a really good day as not longer after finding the Wood Sands I saw a White Stork circling low over the reserve. It had been seen a couple of days earlier but was seen flying off. I was pretty sure I'd seen it in a field just north of the railway lines while I was on the train to Purfleet.

White Stork

This is the fourth White Stork I've seen at Rainham and it has become an annual visitor to the reserve. This individual was ringed so was probably one of the reintroduced Knepp birds but as they're breeding there now I believe they should all be countable.

Among the various butterflies and dragonflies on site, there were a few Clouded Yellows and an obliging Wall but I still haven't managed to catch up with the Brown Hairstreaks yet.

Dagenham Chase & Beam Valley

I visited 13 times but didn't see a great deal. Losing all the water in The Slack has really reduced the attraction of the site this autumn. I spent a lot of time searching the scrubby areas for flycatchers but didn't manage to find any.

I also went to Beam Parklands six times and despite the burnt areas grassing over and looking suitable for migrants, didn't manage to record anything notable.

Other Locations

I managed to visit a few other sites in August: Barking Riverside & Bay (as it's now called on eBird), Becton Creekside, Tylers Common (where a Red-backed Shrike disappeared 20 minutes before I arrived!) and Wanstead Flats (where most of the interesting migrants had left overnight).

Ruddy Darter, Becton

I also had a couple of trips out of London, down to Oare Marshes in Kent to see the regular Bonaparte's Gull and on a Seabird Safari across Biscay for cetaceans and seabirds.

July birding

July typically sees the true start of autumn migration, especially with waders and this was definitely the case this year. There was also plenty of fine settled weather to look for insects as well.

Rainham Marshes

I've started increasing my visits to Rainham after the midsummer break and went seven times this month. I added two new birds to my London yearlist: a Crossbill heard flying over the woodland and a moulting Ruff that was present most of the month.

Ruff with a Black-headed Gull

Also around on the reserve were five Great Egrets, regularly seen feeding out in Aveley Pools. They appear to be a family party so may have bred in the vicinity.

A couple of Green Sands hung around but there was no sign of the hoped for Wood Sand so that'll have to wait for next month. Black-tailed Godwits streamed back in decent numbers, mostly still sporting their summer dress.

Black-tailed Godwits

Dragonflies were regularly seen, taking advantage of the sunny weather. On one particularly day I saw Norfolk Hawker, Lesser Emperor and Southern Migrant Hawker, all recent colonists. I still haven't photo'd the last two so I'll keep trying for those. Butterflies are still a bit thin on the ground, possibly due to the heatwaves we've had drying all the vegetation up. I did manage to see a Clouded Yellow on one visit. As usual, Jersey Tigers were frequently seen.

Dagenham Chase

I put in a lot of effort this month with 18 visits. The Slack continued to dry up during the month despite the odd day of heavy rain and a few days of pumping water into it. Green Sands were present on most days with up to six seen but the best wader on show was a Black-tailed Godwit that remained for the entire day and was my first one on the patch.

Black-tailed Godwit and 2 Moorhen

A Great Egret decided that a stretch of the River Rom was to its liking and remained for a couple of weeks. Although mostly visible from the main road by the entrance to Grenfell Park, it often wandered down the river towards The Chase and could be hard to find.

I spent a lot of time searching the elms and oaks for hairstreaks but couldn't find a single one. Gatekeepers were everywhere and I did manage the odd Common Blue.

I also went round all the ponds and lakes regularly looking for the afore-mentioned London colonists but haven't had any success so far.

Beam Parklands

I visited seven times in July. My local patch was in the news mid-month when a wildfire burnt a large section of it and got quite close to some adjacent houses. This is the third year in a row that there's been a fire here and while the grassland has already started to recover following some rain, the gorse bushes took a severe battering and may not recover.

Bird wise it was fairly quiet until the last week of the month when I saw my first Buzzard of the year and, even better, heard my first ever Green Sandpiper on the patch.

I also popped into Barking Riverside and Mayesbrook Park but both sites were fairly quiet. Hopefully things will be busier in August.

June birding

June is often a quiet month for birding and with long spells of hot dry weather in the capital, it was particularly slow. I usually turn my attention to insecting instead but even that was hard at times with dried out waterways and vegetation.

Beam Parklands

I visited my local patch five times in June and walked up into Beam Valley CP a few times as well. The Cuckoo was still calling and warblers such as Blackcap, Common & Lesser Whitethroats started singing again after raising their first brood. Small and Essex Skippers were both found after a bit of searching along with a few other common butterflies but the only dragonfly seen was Black-tailed Skimmer.

Dagenham Chase

I managed a respectable 14 visits this month. From the middle of the month there were clear signs of the autumn migration commencing with a rise in the number of Lapwings on The Slack (reaching 20 by the end) and the first returning Black-headed Gulls. The water level is severely low at the moment but they are proposing to start pumping water into it this week.

I spent a lot of time searching all the elm trees for White-letter Hairstreak but to no avail. Although there are a lot of elms, there's very few mature ones as the rest have succumbed to Dutch Elm Disease. 

Last year I saw a lot of damselflies on Crowfoot Marsh but haven't found any this year and I suspect it's because of the dogs that go into the water. If the dogs have been treated with a particularly toxic anti-tick/flea treatment it washes off in the water and kills off all the insects.

Despite all this I still managed to find a reasonable number of insects here this month. After finding the first Marbled Whites in the area last year, their colonisation continues and this year they've expanded their range out of Fels Field.

Rainham Marshes

I went to Rainham three times but only did the loop around the reserve once. I was particularly targeting dragons and damsels and managed six species, a fairly low total as it was a struggle to find any damselflies. I was especially pleased to find and photograph Norfolk Hawker as that was my main target for the day.

I also had a wander around the country lanes outside of Rainham Village hoping to find some partridges. I didn't manage any but instead saw a Barn Owl which was probably bird of the month.

Goresbrook Park

This small park is a couple of minutes walk from my house but I rarely visit it as it's a bit hopeless. A river runs through it - The Gores - but is hideously choked with Himalayan Balsam. There's been some attempt to plant trees and shrubs but they're mostly dead which is a shame as it could be a nice place with a bit more effort. I had a wander round looking for butterflies, most of which were feeding on a Buddleia.

Comma

South London

I ventured south of the river a couple of times, first to Epsom Common to look for Black Hairstreak. It was just my second visit to this site, the first being many years ago to see a Little Bittern. It's a fairly easy journey on the train but there are some very specific instructions to follow to get to the hedge the hairstreaks live on. 

As we got there I saw one fly past and then never saw any more for the whole time we were searching. We met a few other people who were also searching but they hadn't found any although they had been seen earlier in the week. I'll give it another go next year. At least there were other butterflies and insects around and we got great views of White Admirals.

The following week we went to Crossness where the Ruddy Shelduck was located on the foreshore. It was one of the hot days so we only walked part of the route and took a bus  back to Abbey Wood station.

The dry summer has taken its toll on my garden and everything is looking like it belongs in the Atacama Desert. However, the few flowers that are thriving have been a boon for insects and I found a few Small Skippers on the lavender in my front garden and, best of all, a Bee Beetle in the back garden, a really stunning insect.
