Seasons collide

As the schools go back and we enter meteorological autumn of course the weather has decided to go all 'high summer' with the first anticyclonic system to reach our shores since June, as I write this in early September. It's been a bit of a shock to the system to dig out the shorts and suncream again after what felt like a protracted bout of autumnal weather in recent weeks. It's also scuppered the first week and a half of September from a birding point of view, in some ways, with many migrants clearly making a quick getaway in the fine weather. Vismig in particular has been pretty poor so far, but I'm still hopeful for better to come in the next few weeks.

It's still been an enjoyable start to autumn proper though, with plenty of bits to talk about in this ten day period. 

1st September

It was our fifth wedding anniversary today, so we headed down to Ferring for breakfast and a walk along the beach followed by a stroll around Parham gardens.

At Ferring, avian highlights came in the form of three Ringed Plover and two Sanderlings among around 75 Turnstones roosting on the beach, and at least ten Sandwich Terns and three Common Terns past at sea. A lone Teal briefly landed offshore before flying off west. Eight Oystercatchers flew west while we were having breakfast.

The highlight of the morning though came when Kate asked 'what's that flapping about on the beach there?' Upon closer inspection, it turned out to be a Convolvulus Hawkmoth, presumably newly arrived from across the Channel. It was struggling to stay clear of the incoming tide so I gently scooped it up and placed it in a patch of vegetation at the top of the beach, safely away from a nearby flock of House Sparrows. A remarkable encounter!

Parham was, comparatively, pretty quiet, though raptors were much in evidence in the by now warm afternoon sunshine, with at least half a dozen Buzzards thermalling overhead along with a couple of Red Kites and a Sparrowhawk. At least three Ravens were around too, and I commented to Kate that it's amazing how quickly the species has spread into this part of West Sussex, going from being a relatively infrequently occurrence when we moved down here in 2017 to now being a daily event. 

2nd September

An early morning loop of Pulborough Brooks produced 58 species including a pleasing selection of waders on the North Brooks (seven Black-tailed Godwits, four Ruff, three Green Sandpiper, four Snipe and 120 Lapwing) but sadly not the Spotted Redshank seen by Chris and Juliet et al the previous day. At least a dozen Yellow Wagtails were with the cattle near Winpenny and a Spotted Flycatcher was among a mixed flock at the picnic area on the way down to Nettleys.

Ruff and Lapwings

Later in the morning, while at our allotment, I noted a Swallow flying over carrying food, so presumably still feeding young in a nest. Later still, a Cattle Egret flew low over the A29 as we were driving home. 

3rd September

A morning walk from home with Kate and B produced a couple of Willow Warblers and three Spotted Flycatchers up Sandy Lane. 

A check of the North Brooks at Pulborough en route to Knepp was again lively on the wader front, with Wood Sandpiper the highlight along with eight Black-tailed Godwits, two Ruff, heard-only Green Sandpiper and at least 140 Lapwings. At least five Yellow Wagtails were with the cattle up towards Brookgate Farm, one of the Knepp White Storks was also wading about on the North Brooks but too distant to read the ring number, and a Hobby was hawking overhead.

Yellow Wagtails

Knepp itself was rather quiet on the bird front, but a check of Southlands Farm in West Chiltington on the way home produced singles of Tufted Duck and Shoveler on the little pool there; both new species for me at this site. 

4th September

After dropping B at nursery this morning I headed up to Amberley Mount, hoping I would find it above the fog level. Frustratingly, the fog was sitting just at the height of the Downs here and took a little while to clear. As I reached the top of the western slope, it had thankfully mostly dissipated and the first birds to reveal themselves were three Wheatears on the fence line around the sheep fields. There were several Yellow Wagtails calling and occasionally flying up from among the sheep too - I reckoned at least six by the end of the session here. Other highlights from a lively couple of hours included a minimum of ten Redstarts (mostly on the southern slopes), a few Willow Warblers, singles of Whinchat, Stonechat, Corn Bunting and Spotted Flycatcher, and a Marsh Harrier powering north. Swallows and House Martins were trickling west/south-west throughout the session, and three small groups of Siskin were also heard flying over, seemingly heading in the same direction.

5th September

A rewarding early morning jaunt from home produced a 1km year tick in the form of a Whinchat in the scrub near the railway crossing at Waltham Brooks. Atypically, it didn't hang around for any photos as it flew strongly off towards the river almost as soon as I'd lifted my bins. This followed a flyover Yellow Wagtail - species 104 for the Watersfield Farmland hotspot. At least one Yellow Wag was heard around the cattle at Waltham Brooks too, with other highlights including at least three Lesser Whitethroat, half a dozen Common Whitethroat, three Snipe (my first of the autumn here), two Stonechat, Water Rail, three Tufted Duck and a Little Grebe.

A mid-afternoon skywatch from the fields near home proved rather quiet in the searing heat, though at least 100 Swallows were milling about, some purposefully heading WNW, with a few House Martins in tow. An adult Lesser Black-backed Gull also drifted the same way.

6th September

After a morning garden safari at Knepp (highlights of which were Hummingbird Hawkmoth and a lot of hornets!) I made an impromptu decision to pop down to Mill Hill near Shoreham, even though the Red-backed Shrike hadn't been reported for a couple of days. I hadn't been here for a few years and it was lovely to have a stroll round, even if it was blisteringly hot and the shrike didn't put in an appearance. 

Highlights included two Spotted Flycatchers in the scrub north of the car park, a heard-only Redstart and, best of all, a Honey Buzzard which suddenly appeared to the west of the hill, flying away from me before gaining height, banking and heading north. Annoyingly, a combination of the element of surprise, suncream on my glasses and terrible light meant I wasn't able to get any useable photos of it, so the record shot below is purely for posterity. Mill Hill is always a great site for butterflies and today didn't disappoint, with several Adonis Blues about and my first UK Clouded Yellow of the year.

On the way home I briefly stopped off at Pulborough for a scan of the South Brooks from Hail's View which produced just a couple of Green Sandpipers. 

7th September

A dawn walk from home was rather too hampered by fog and low light to be anything other than a nice breath of cool air after a sticky night.

After dropping B off at nursery I decided to head over to the farmland and private reservoir near Petworth. The temperature was already climbing fast and it was uncomfortable to be in the sun for any length of time. It proved to be a fairly lively 90 minutes or so here though, with 42 species recorded. Highlights were a hotspot first Redstart briefly in flight along a hedgerow, Wheatear, two Common Sandpipers at the reservoir and at least two Ringed Plover flying over, calling, seemingly heading west but not seen.

8th September

Not much birding today aside from a trip to Warnham LNR with B. My first visit to this reserve for a while, today it produced 32 species including Kingfisher, Marsh Tit and the usual assortment of wildfowl and gulls. 

Best from the garden moth trap at home in the morning were two Light Emeralds and the first Centre-barred Sallow of the autumn.

While in the garden in the afternoon, singles of Yellow Wagtail and Siskin flew south and south-west, respectively. 

9th September

A morning safari at Knepp was scorching hot and rather quiet on the bird front, though the odonata put on a good show, especially Migrant Hawkers which seemed to be everywhere we looked. 

An evening walk out to the river at Thorndale Bridge was a relief after the heat of the day, and produced a juvenile Marsh Harrier quartering just across the river at Amberley and a Great White Egret which flew across to Amberley from Waltham Brooks, the latter my first record for this eBird hotspot.

10th September

The moth trap was out again overnight which produced a new for the garden Marbled Green. Prior to emptying the trap, an early morning loop of Waltham Brooks and Thorndale Bridge produced a/the Great White Egret again, flying in from Amberley before turning and heading up the river towards Pulborough. Also noteworthy were two Whinchats along the river bank, a Green Sandpiper which flew in from the north and dropped in under Greatham Bridge and a heard-only Kingfisher.

Later in the morning, half a dozen Siskins flew high south-west over the garden. There already seem to be more of these around lately, even if just moving through. Fingers crossed for a better winter ahead for them and other winter finches.

With rain forecast around lunchtime I headed over to the private reservoir near Petworth hoping for a wader to drop in. In the event, there was just a Common Sandpiper of note on the deck, although at least two Ringed Plover were again heard flying over, 16 Pochard was a fairly high count here and at least 70 Swallows drifted east ahead of the approaching weather.
