July Skies

Another mixed bag from the past ten days or so, as we teeter on the brink of August and the start of the harvest or Lammas season (1st August - halfway between the summer solstice and the autumn equinox).

I think that means I'm officially allowed to start using the 'a' word now? It's certainly fair to say the weather has been decidedly autumnal for the most part in the past fortnight. The dominance of low pressure, Atlantic weather systems delivering day after day of squally, grey, drizzly conditions has been particularly strange and unsettling given the news and images coming from further south in Europe. I remember something someone said to me a few years ago which has really stuck with me - nobody alive today has known what it's like to live in stable climatic conditions, and that is becoming more and more evident as each year passes.

In the context of local birding and other wildlife watching, it's been a fairly quiet and unremarkable period again, although it's clear we are experiencing a particularly good year for butterflies after a slow start back in the spring. It's been the best Purple Emperor season at Knepp since the best ever year of 2018 and everywhere I look at the moment I seem to be seeing Red Admirals. I had a pretty extraordinary count of ten together on the garden Buddleia the other day!

20th July

I headed out late morning for a fairly lengthy walk from home up towards Fittleworth to scan the valley across the Rother to the north. Raptors were out in force, with multiple Red Kite and Buzzard, at least three Kestrels and a single Sparrowhawk noted during an hour's skywatch here. 

Otherwise it was a relatively quiet session, though at least 35-40 Swallows around the stables at Ashurst were nice to see, as were two juvenile Green Woodpeckers in the same area. 

21st July

A quick look at Pulborough Brooks this morning, scanning the South Brooks from behind the visitor centre. Among 14 Little Egrets (there have been up to 21 recorded here in recent days) were singles of Greenshank and Green Sandpiper on the pool at West Mead while three Red Kites were soaring together in the distance.

En route to Knepp I briefly stopped to check the pool at Southlands Farm in West Chilt which again produced a Green Sandpiper. 

Knepp itself was again on fire, with a female Purple Emperor greeting me as soon as I arrived at the Operation Wallacea campsite. Out in the wildland with my group, highlights included a Barn Owl flying from a known nest site, the very vocal Sparrowhawk family near their nest site and a group of 31 White Storks kettling together over the Exmoor herd towards the far southern end of the estate.

Purple Emperor

After Knepp I headed down to Goring to catch up with David C. While we were chatting by our cars, a juvenile Yellow-legged Gull flew past with a juvenile Herring Gull in tow. After poorly David headed home I indulged in a c.45-minute seawatch from the beach which proved to be quite lively, with three Whimbrel and two each of Dunlin and Mediterranean Gull heading west, and two each of Sandwich Tern and Gannet feeding offshore. 

Whimbrel

Mediterranean Gull

22nd July

This morning I headed down to Medmerry, primarily for work-related reasons but it was a nice opportunity to have a little walk about and check out the Stilt Pool, which yielded singles of Common Sandpiper and Black-tailed Godwit among the Oystercatchers, Cormorants and Black-headed Gulls.

On the way home, with rain due to start at any minute, I had a quick check of the private site near Petworth which produced a juvenile Little Ringed Plover and at least 80 Swifts but little else of note.

No more birding after that as the weather turned decidedly October-esque, with heavy rain and wind - lovely!

23rd July

A brief look at Waltham Brooks en route to a day working at Knepp proved fruitful, as the very last bird of the session was a 1km year tick and Waltham Brooks lifer in the form of a Whimbrel powering south/south-west overhead and disappearing down the valley towards the Downs.

Knepp delivered again on the Turtle Dove front (it's been an astonishing year for the species there) with one seen flying up from a main path not long after I arrived. Otherwise it was mostly about the butterflies today, including what surely must be one of the very last Purple Emperors of the season.

A quick scan of the pool at Southlands Farm in passing on my way home again produced a lone Green Sandpiper. 

24th July

After dropping B at nursery I popped to Pulborough for a quick look at the North Brooks where I found a decent selection of waders - 10 Avocet, 24 Black-tailed Godwit, 3 Green Sandpiper, 2 Little Ringed Plover, 2 Common Sandpiper and a single Greenshank - and, sadly, a rather sickly looking adult Mediterranean Gull. 

Avocets

Black-tailed Godwits

25th July

Not much birding today, but it was a pleasure to lead a safari for members of the RSPB Youth Council at Knepp. Highlights included two Turtle Doves (one singing and displaying and another in flight), two Sedge Warblers (Hammer Pond) and my last Purple Emperor of the year. 

26th July

A diverse day which started with a walk from home up to the river at Thorndale Bridge, and a brief skywatch from the fields near home. It certainly felt autumnal, with a lovely fresh feel to the air and a light mist over the river, but it doesn't feel as though the season has quite got into swing yet, ornithologically speaking. Highlights were a Little Egret high east, adult and juvenile Lesser Black-backed Gulls high south and a Water Rail squealing along the river.

Little Egret

Swallows

Mid-morning I headed back down to Medmerry for work. While I was there I had a look at the Stilt Pool which yielded 3 Common Sandpipers, a Green Sandpiper, several Oystercatchers and a heard-only Ringed Plover. A quick look at the sea produced 3 Sandwich Terns, 8 Mediterranean Gulls and a single Gannet. While I was down at the coast I also dropped in to Church Norton briefly which produced a pleasing selection of waders including at least 3 Whimbrel, 2 Sanderling and a Bar-tailed Godwit.

Sandwich Tern

Early afternoon I met up with David C at Pulborough, and a stroll round the reserve produced a few bits, notably 10 Avocet, 2 Green Sandpipers and 3 Black-tailed Godwits on the North Brooks and a single White Stork (GB6S from Knepp) following the tractor around on the South Brooks, just like they're supposed to!

Brown Argus

27th July

A drizzy day, with more than a hint of autumn in the air, only exacerbated by the sound of a Curlew flying over Knepp Castle as I was in the orchard prepping for a garden safari. Other highlights here included a heard-only Raven and a Hummingbird Hawkmoth; the latter very obligingly dropping in to feed on a Buddleia as I had stopped with my group to chat about the importance of nectar sources in a garden!

On the way home I dropped in at Waltham Brooks for half an hour which produced another heard-only Raven, two Cetti's Warblers in the reeds and willows by the main lake and seven Gadwall on the lake itself.

28th July

A walk from home this morning, checking local fields and scrub and a skywatch proved fairly quiet aside from a Hobby terrorising the Swallows before flying off north.

A check of Amberley after dropping B off at nursery produced singles of Redshank, Raven and one of the White-tailed Eagles. 

29th July

Another local session on foot early morning proved quite productive with a Hobby again chasing Swallows about, a Peregrine high south-west and at least 50 Swifts drifting slowly south. That's more like it! I'm excited for my first full autumn vismigging from this area, I do think the funnel effect of the Arun Valley so close to the South Downs could be quite interesting.

Later in the morning, a Big Butterfly Count in the garden at home produced an impressive ten Red Admirals together on the Buddleia. I honestly can't remember such a good summer for the species, they just seem to be everywhere at the moment!

Red Admiral

30th July

A really enjoyable couple of hours out first thing this morning, although it again was feeling unseasonably fresh ahead of the rain that arrived later in the day. First up I checked the private reservoir over near Petworth which yielded very little aside from a noticeable increase in Little Grebes and a flock of at least 450 Jackdaws in flight off the nearby fields.

A visit to Lavington Common produced a Spotted Flycatcher in the pines round the car park and a family group of at least four Dartford Warblers a couple of hundred metres north of the car park. 

Dartford Warbler

Finally, a stake-out on the viewing platform at Burton Mill Pond produced a welcome return encounter with the red-ringed Great White Egret I last saw here back in late January. She's 'ACA', a female ringed in the nest at RSPB Ham Wall back in May 2022. Interestingly, another juvenile from the same ringing scheme, ACJ, has been hanging out at Warnham LNR quite a bit recently - so definitely worth taking a closer look at any individuals of this species you see out and about in Sussex.

Great White Egret

Late afternoon, a Hobby made two low passes over home, first heading south-east, before flying back west.

31st July

Another very autumnal day, weather-wise, with a blustery south-westerly and drizzle/light rain persisting until mid-afternoon. After dropping B at nursery I swung by Pulborough for a brief check of the North Brooks. As I walked down, a tight group of around 25 Swifts drifted west. On the North Brooks were 36 Black-tailed Godwit, 30 Lapwing, 16 Black-headed Gulls and singles of Greenshank and Snipe, the latter only making its presence known when a Buzzard flew through low and flushed everything. 

On the way home a quick scan from the river bank near Greatham Bridge produced an incredibly close encounter with a Kingfisher, dashing past upriver. A return visit to Waltham Brooks late afternoon produced another or the same Kingfisher in flight over the main lake, a Hobby flying east, Peregrine south and a juvenile Marsh Harrier hunting and drifting north. 

Marsh Harrier

Dust and lowering skies

Given that this is supposed to be the relatively quiet period in the birding year, the past fortnight or so has actually been one of the most enjoyable periods of 2023 so far for me, from a local birding perspective. The clear highlight, of course, was finding a Marsh Warbler just a few hundred metres from home, which was still present at the time of writing (update: it has since departed, it seems).

Otherwise it's been a fairly steady stream of waders, Cuckoos and various less common breeding species, plus some of the first high summer butterflies and odonata of the year.

Weather-wise, it's been a relief to get some much-needed rain in the past week or so, including some particularly impressive thunderstorms. I have been once again reminded how spectacular lightning is when it flashes around the South Downs, as storm fronts slowly approach Sussex from the English Channel.

12th June

A fairly brief whizz round Pulborough Brooks this morning produced a pleasing selection of species including 3 Little Ringed Plover, Cuckoo, Dunlin, 10 Avocet, my first Redshank chick of the year, a single White Stork on the North Brooks and at least three Nightingales still singing. 

13th June

I was out of the house before 05:30 this morning (not something that has happened often lately) with my plan being to head up the Arun to Waltham Brooks then back via the sewage works. In the end I never even made it as far as the river as around 500m from home my attention was drawn to an odd Acro song coming from an area of mixed rank vegetation right next to the railway line at Thorndale Bridge. I've often heard Cetti's Warbler in this spot but not Reed Warbler as far as I can remember, so it instantly stood out as rather out of context. This, combined with the fact I was hearing elements of mimicry (including Goldfinch, Swallow, Blackbird, Blue Tit and even Bee-eater) immediately rang alarm bells and my thoughts quickly turned to Marsh Warbler. I positioned myself near the railway bridge and, over the course of the next hour, hoped that the bird would show itself well enough to get some record shorts and audio recordings, which it dutifully did, and I left site at 07:00 very happy I had self-found my first Sussex Marsh Warbler and, indeed my first anywhere in the UK for around ten years!

Marsh Warbler

14th June

A decent session at Burton Mill Pond this morning produced 43 species in 100 minutes. Highlights included a female Mandarin with young on the outflow near the mill house, the Great Crested Grebe pair feeding three young on the main pond and a Little Owl hunting along the fenceline at Burton Park Farm. Two Siskins over Newpiece Moor were also noteworthy, given what a poor first half of the year it's been for the species. Apparently, they were once known as 'barley birds' owing to their tendency to reappear around the onset of high summer (i.e. the time that barley is ripening for harvest), presumably due to dispersing young birds and post-breeding adults.

15th June

Not much birding today aside from an hour or so at Thorndale Bridge in the evening, where I bumped into Michael and Dan Booker, hoping to connect with the Marsh Warbler. Sadly, we didn't have any luck this time, despite a Reed Warbler doing its best to convince us otherwise, by throwing in occasional bursts of Goldfinch mimicry into its song - strange, considering I hadn't heard Reed Warbler here before, but a quick Google search on my phone brought up a BB paper which suggested Reed Warblers which spend any length of time in the vicinity of Marsh Warblers have been known to incorporate mimicry into their songs. A Barn Owl kept us entertained, hunting around Wharf Field, while there were again plenty of Swallows flying about overhead and a Nightingale called briefly by the railway line as I was heading for home. 

16th June

An early two hour session at Pulborough this morning proved to be quite lively. Highlights included all three egrets (9 Little Egret and one each of Great Egret and Cattle Egret), two each of Ringed Plover and Little Ringed Plover together on the North Brooks (which was a bit confusing at first as it's very unusual to see these two species together here at this time of year), singles of Dunlin, Black-tailed Godwit and White-tailed Eagle and three White Storks (GB0S, GB6S and GB3U from Knepp). There was still plenty of birdsong around including Yellowhammer and Stonechat near Winpenny and a few bursts of Nightingale around the main trail. There were plenty of young birds about too, especially Whitethroat, with at least three family groups seen. 

White Storks

In the afternoon, I headed down to Worthing with B for a walk around Brooklands Park where the highlights were a newly fledged Reed Warbler, a few Swifts and House Martins, two Cetti's Warblers and two Great Black-backed Gulls. On the way home we dropped in at Knepp to watch a bit of the White Stork ringing.

17th June

Not much birding today other than a short local walk in the morning which was uneventful. While I was at Knepp in the afternoon and evening, news emerged that the Marsh Warbler had been rediscovered along the riverbank at Waltham Brooks so I swung by on my way home in the hope it might still be singing well after sunset. Sadly no luck, just the odd burst of song from Sedge and Reed Warblers. It was quite impressive and more than a little unnerving to be out on the riverbank as lightning flickered distantly all around, but I was glad to get home before the big storm hit in the small hours!

18th June

WeBS day today so I headed over to the private reservoir near Petworth, which produced the usual fare on the water - Coots, Tufted Ducks, Mallards and singles of Mute Swan and Great Crested Grebe - plus two Little Ringed Plovers on the shore. The best in this area though was discovering an active Barn Owl nest in a farm building, with an adult seen leaving a box which I was able to see contained three small chicks.

The owl theme continued later in the day, as a dusk safari at Knepp produced heard-only Barn Owl and at least two squeaking juvenile Tawny Owls near the campsite. Anecdotally, it seems to have been an excellent year for breeding Tawny Owls, as I've been seeing and hearing them all over the place, especially at Knepp, where at least three pairs have bred in the Southern Block. Also of note this evening was a Peregrine over the Southern Block, not a raptor I see here all that often. 

19th June

Not a great amount of birding today due to other life stuff.

20th June

The first butterfly safari of the season at Knepp this morning produced my first White-letter Hairstreaks of the year, but otherwise not a massive amount of lepidopteran interest, as it was decidedly cool and grey, with even a bit of light rain in the air at times.

21st June

An hour early afternoon checking out the local fields near home for the first time in a while didn't produce much in the way of birds, but it was great to discover a colony of White-letter Hairstreaks in some hedgerow Elms just a couple of hundred metres from the house - in an area I had actually earmarked for the species a few weeks back. It's always nice when that happens! Typically they were either whizzing about at high speed above the trees or hidden up in the foliage, so no useable photos really...

An evening session at Thorndale Bridge and the very south-western corner of Waltham Brooks produced a great selection of species, most notably the Marsh Warbler singing in reeds/willow on the south side of the river. This is the first time I've managed to catch up with this elusive bird since finding it last week. It does seem to be splitting its time between the original location and this spot along the river. It was really belting out its song this evening, until just before 22:00 when it went quiet. Mimicry included Goldfinch, Swallow, Wren, Bee-eater, Blue Tit and Nightingale. 

22nd June

Proving the old adage that it's better to get in the field for a few minutes than not at all, this morning I dropped in at Waltham Brooks for all of 15 minutes on my way to Knepp, but it turned into a surprisingly great little session. The Cuckoo was still singing away along the river, my first 1k Little Grebe for a while was on the main lake but, best of all, a Common Sandpiper was perched up on the post in the middle of the lake before taking flight and disappearing out of view towards the western end. A 1k year tick for me, taking the local total to 116 (146 for the wider 10k). Also my first locally for four weeks - too early to call it the first returning bird of autumn?

Song Thrush

After a great butterfly safari at Knepp which yielded my first Purple Emperors of the year, an evening session in the Beaver enclosure produced some equally breathtaking encounters with the resident pair, including a spectacular tail slap just as we were about to leave! It really is astonishing what a great job they have done of engineering the wetland habitat in this part of the estate in the past 18 months or so. Avian highlights here included multiple singing Chiffchaffs, a couple of croaking and whistling Nightingales and what sounded like at least two fledgling Bullfinches calling in the scrub.

23rd June

The planned early start didn't happen this morning but, after dropping B at nursery, I headed over to Amberley for an hour walk from the castle entrance up to the river bank and back. A pleasing selection of 40 species were recorded including Cuckoo, Hobby (putting the wind up around 40 Swifts gathered over the castle) and a Mute Swan pair with seven cygnets.

Mute Swans

An evening session up the river from home to Waltham Brooks sadly didn't produce the Marsh Warbler, but three singing male Cuckoos were pretty remarkable to hear so late in June (as reported by Pete Hughes the previous evening too), and a female Mandarin with eight ducklings on the main lake represented my first confirmed breeding for the site.

Summertime Blues

Continuing the 'it's a bit quiet' theme from my previous blog post early July didn't really produce much in the way of avian fireworks at Pulborough. Thankfully though the first waves of returning waders have been keeping the interest up and of course there's also plenty of invertebrate interest at this time of year, but more on that later.

Early morning looking across Winpenny Brook to Hanger Wood

The waders really started getting going as June gave way to July with the usual early movers beginning to arrive in the form of some good accumulations of Little Ringed Plover (peaking at eleven on 28th June), Green Sandpiper (nine on 10th July), Black-tailed Godwit (ten on 10th July), Common Sandpiper (three on 17th July) and odds ones and twos of Dunlin and Greenshank. The breeding Redshanks and their offspring have all but cleared out with just the odd juvenile lingering now, while Lapwing numbers are beginning to increase with presumably many of the local breeders among them. Mind you, like many wetland sites across the UK this summer, the Brooks is in need of a good top up soon to maintain interest for any waders or wildfowl.

Talking of wildfowl, well it's a bit quiet there too really, with just handfuls of Teal and the odd couple of Shoveler mixed in amongst the hoards of eclipse plumage Mallards lately, all crammed into what's left of the water on the North Brooks.

Gulls are rarely numerous at Pulborough so it's been good to hear a few reports of Mediterranean Gulls dropping in recently, although I've missed most of them myself! I also managed to miss another local Osprey when one flew over Hardham a couple of Sundays ago. The observer (Martin Lanaway) reported the alarm calls of Herring Gulls drawing the bird to his attention which is particularly frustrating as I was at home at the time and remember hearing some Gulls calling but foolishly was in a bit of a rush to leave the house and so didn't investigate further. I bet it must have flown right over the Brooks/garden!

As is typical for the time of year, most of the migrant passerines are keeping their heads down now, with odd squeaks, tuts and whistles from Lesser Whitethroats, Nightingales and others staying largely hidden in the undergrowth. There seem to be more Meadow Pipits around the past few days and I've noted the odd Sand Martin flying strongly south, so some small signs of change there. I'm hopeful that the coming weeks will deliver a few of the glaring omissions from my patch year list such as Yellow Wagtail and Redstart but only time will tell.

Grey Heron

Somewhat unexpected towards the end of June and early July was a singing Woodlark, rather bizarrely favouring the area between Uppertons Field and Hanger Wood. Whether it was the male of the pair that had been holding territory on the heath up until the 'Beast from The East' arrived or a new individual is of course impossible to know but it was still lovely to hear that lilting song echoing around the Brooks again for a few days - it seems to have moved on again now. Despite increasing numbers of Starlings (over a hundred on the 13th of this month) I've still been unsuccessful in gleaning out a Pastor roseus to add to the patch list. Indeed, I've not had a patch tick of any kind since the Common Terns on 20th June, so another reason to look forward to the autumn!

As I mentioned in my intro though, Pulborough is a great place to find all manner of non-avian wildlife, especially in the extraordinarily hot and dry summer we're currently experiencing. I told myself I'd try to sharpen my Odonata ID skills this year and Black Pond in particular is the perfect place to do just that. Black Darter is a species I'd never knowingly seen before until this year, so I was particularly pleased to see several here after a tip-off tweet from Alan Kitson. The woodland butterflies have been out in force too, with White Admiral and Silver-washed Fritillary putting on good shows in Black Wood, and still plenty of Purple Hairstreaks around, while the first Brown Hairstreaks have also begun to emerge now - best seen along the paths near the Hanger or down to Nettley's Hide.

Another place that's always worth a visit at this time of year - particularly for butterflies - is Knepp Wildlands. After reading of the incredible numbers of Purple Emperors being recorded at the end of June, I visited on the 30th with Kate and in just a couple of hours we saw at least forty of these majestic butterflies cruising about all over the place, along with a similar number of Purple Hairstreak. I've been aware of the White Stork re-introduction project for a while but even so it was quite surreal to see one casually gliding overhead at one point. I returned again a couple of weeks later with Charlie Peverett and Chris Ball, neither of whom had been before. As our visit was earlier in the day and a little later in the season we 'only' saw a handful of Purple Emperors this time but also had a bonus couple of Turtle Doves in flight. It's amazing to think Knepp only started recording this species again in 2007 and this year they have had eighteen singing males.

"There ain't no cure for the summertime blues", sang Eddie Cochran. Well, all I can say is Eddie clearly wasn't much of a naturalist. The summer may be quiet for birding but there's always stacks of other stuff to look at and autumn proper really isn't too far away now, and that's a heartening thought to cheer up any birder suffering with the blues.
