Mid-October

My shoulder injury recovery continues so it was pretty much exclusively 1km from home birding on foot again for this ten day period. It certainly feels as though we have turned a corner, seasonally speaking, as we move into the second half of October. There were still a few summery stragglers making an appearance but I also finally recorded my first Brambling of the autumn (of the entire year in fact, so dire a finch winter as we had last year!). The unusually warm weather has also all but gone now, as I write this, and we have had the first couple of frosts of the year plus the expected October wind and rain. Indeed, parts of the 1km area are getting decidedly soggy now, though not entirely impassable yet.

11th October

A grey and drizzly start to the day saw me checking the moth trap which held a respectable 39 individuals of 21 species, including new for the garden Red-line Quaker, Black Rustic (x 4), Large Wainscot, Barred Sallow, the spectacular Merveille du Jour (x 2) and the migrant Rusty-dot Pearl. Talking of migrants, it seemed relatively quiet on the vismig front overhead while I was emptying the trap, but I did note a couple of Redwings over and eight Swallows powering south.

Once the trap was emptied I headed out for a loop of Thorndale Bridge, the local farmland and Waltham Brooks. Aside from another group of Swallows heading south-east and a couple of Skylarks south, the low cloud and mizzle seemed to be hampering any migratory activity, so I didn't linger too long at Thorndale Bridge. Highlights here were four Snipe flying about (presumably the same group seen yesterday), a Stonechat, and a female Marsh Harrier which flew upriver. Up at Waltham Brooks the best were two Pintail, three Little Grebes and a single Tufted Duck among the usual wildfowl on the lake plus heard-only Kingfisher, a couple of Swallows and Redwings over. It was also noticeable that Chiffchaff numbers are on the up, with a conservative count of 15 recorded, especially congregating in the sallows on the western side. There was again a curiously calling individual here giving the plaintive 'hew' call, as heard at Thorndale Bridge recently. 

12th October

A similar morning to yesterday. A check of Waltham Brooks again produced two Pintail on the lake along with 10 Shoveler, 13 Gadwall and 15 Teal. Presumably the same quartet of Snipe were again flying about overhead, around 50 Lapwings were up in the air over Widney Brooks and two Green Sandpipers flew over my head near the railway line and dropped down towards the main lake. 

It had been decidedly quiet overhead early morning but on the way home I noticed a bit of a movement of hirundines, so decided to stop off for a skywatch, which proved to be fairly lively. Aside from over 100 House Martins and 20-odd Swallows moving south, the clear highlights were a heard only Golden Plover and a beautiful adult male Merlin which flew fast and quite low over the field where I was watching from, before turning, gaining height and powering off south towards the Downs. Actually my first record for this particular eBird hotspot, although my third record of the autumn locally. 

13th October

A proper October day of wind and rain. Late morning a break in the rain saw me heading out to the local farmland for a bit of a skywatch, perhaps rather over-optimistic given the brisk south-westerly (F5, gusting 6-7). Surprisingly, it was actually a decent 90 minutes, with highlights including three Woodlarks east together (it really is turning into a good autumn for them locally) and a light trickle of hirundines pushing straight into the wind. Particularly impressive was a group of ~20 Swallows which after making one failed attempt to get through fairly high up then dropped down to just a few metres above the ground and powered on into the headwind. 

14th October

The cold morning after the squally night before. Today felt like the first proper crisp morning of the autumn, and I headed out on foot just before 7am wondering if I had under-dressed given the brisk westerly. An hour's skywatching from the local farmland proved fairly lively with a steady stream of Siskins and a few Redpolls, Meadow Pipits, Chaffinches, etc, mostly heading south-west. One species I certainly didn't have on my radar for the third weekend of October was Common Redstart so it took me a moment or two to process what I was looking at when I noticed a passerine flicking about in a nearby hedgerow. Indeed, the way it was lit in the morning sunlight initially brought to mind Red-flanked Bluetail, and it was a heartstopping couple of seconds before I realised I was looking at something rather more mundane, albeit very late. My first record of the species locally since 7th September and undoubtedly my last one of the year. Strangely enough, Ed Stubbs also had one this morning up in Surrey, so perhaps a little late push of Scandinavian ones moving through?

The rest of the day didn't include much birding, although a trip down to Worthing with Kate and B (primarily to deliver a Knepp talk) did also include stopping at Marine Gardens for lunch, which featured flyover Siskins (5) and Redpolls (3). 

15th October

WeBS count day today so Kate kindly drove me over to the private reservoir near Petworth to carry out the survey; my first visit here for four weeks (I normally tend to visit at least once a week). It was usual fare on offer really, though 55 Tufted Ducks represented my highest count here, while 20 Pochards was one short of equaling the record count. Otherwise, highlights were 54 Egyptian Geese on the shore of the reservoir and at least 15 Swallows and a couple of House Martins feeding over the nearby farmland.

Later in the day I went for a stroll from home, highlights of which included at least five Lesser Redpolls at Thorndale Bridge plus the three White-tailed Eagles thermalling together distantly towards the Downs. Despite the chilly air temperature the warm sun was clearly coaxing plenty of raptors into the sky, as I also had a Goshawk sparring with a Buzzard to the south of Watersfield. Single Stonechats were at Thorndale Bridge and Waltham Brooks while a few Swallows, Siskins and a couple of Skylarks were noted flying over, heading south/south-west.

16th October

A lively morning of local vismig, first from the farmland near home and then up on the high ground to the west, began with two vocal Merlins briefly dogfighting overhead a couple of hundred metres from home before separating and flying off west and south-east. Another Woodlark flew high-northeast, while there was just the slightest hint of some early Woodpigeon movement. Finches were clearly moving in good numbers but seemed to be for the most part too high, hence the change in watchpoint an hour or so into my watch. From here, almost immediately I was seeing and hearing Chaffinches, while after 15 minutes the distinctive call of Crossbills signalled the approach of a flock flying from north to south which I somehow never managed to get eyes on, but it sounded like quite a few. Just a few minutes later another flock of 14 flew south. Finch totals from the morning included 87 Chaffinches (mostly west), 50 Siskins (mostly west) plus a few Redpolls, Linnets, Goldfinches, etc. Curiously notable by their absence again were thrushes with just five Redwings leaving roost along River Lane the only ones noted.

17th October

With this welcome spell of easterlies continuing, this morning saw me back up at the high ground to the west of Watersfield for another vismig session. Initially the wind was calm and it was a surprisingly brighter morning than had been forecast, which didn't necessarily suggest much in the way of movement. I was wrong though as, twenty minutes into the watch, I noticed a line of geese approaching high from the north/north-east which I quickly realised had to be Brent Geese, owing to their dark colouration, short necks and generally compact shape, plus the distinctive wavy line flock formation. They weren't calling or, if they were, I couldn't hear it over the strengthening breeze, and because they were really pretty high I also spectacularly failed to achieve anything in the way of a useable record shot with my one-handed bridge camera attempts. Still, one of those memorable vismig moments that put it all into context, as these Arctic travellers near the end of the journey, likely bound for the south coast via Watersfield! Other highlights this morning included the first clearly moving Grey Herons I've seen locally this autumn (two lots of three west), a few Redwings and Fieldfares west (60 and 54), three Swallows south, four Crossbills west and a steady trickle of Skylarks. 

A check of Thorndale Bridge late afternoon produced three Marsh Harriers over Amberley, including a beautiful adult male hunting low over the marsh just the other side of the river from where I was stood, plus a White-tailed Eagle briefly in flight and a female Mandarin flying downriver. 

18th October

A remarkable 58 species in just over an hour at Waltham Brooks this morning including my first Brambling anywhere this year (!) heard flying over, a first winter Goosander on the lake and two Great White Egrets which came in from the west and dropped down near the main lake. There has been clearly been quite an arrival of this species in Sussex as there were also records of seven at Arundel WWT this morning and five at Pulborough Brooks later in the day (perhaps all relating to the same birds) following on from a count of 11 flying past Climping yesterday. 

A rather late flock of House Martins flew over towards Amberley with a Swallow in tow and, on a more wintry note, the easterlies had clearly delivered more ducks to the reserve, especially Wigeon, of which at least 25 flew to the main lake. A flock of 11 Fieldfares were flying about in the scrub while around 30 Siskins were near the sewage works. A few gulls were flying over too, including two Common Gulls.

19th October

I was giving a Knepp talk in Staines last night, after which I stayed with friends in Surrey before making my way home mid-morning. The walk home from Pulborough station took me past Widney Brooks and through Waltham Brooks and the local farmland. It was all distinctly less lively than yesterday, with barely 30 species recorded at Waltham Brooks this time around. Teal numbers had increased to at least 130 but otherwise waterbird diversity was rather poor with just 80 Mallard, 3 Gadwall, a few Coots and a single Little Grebe. Away from the lake, there were two Stonechats in the scrub and a Mandarin flew downriver. 

20th October

A loop of Thorndale Bridge and Waltham Brooks this morning produced a few bits, especially at the former looking over towards Amberley where there were clearly lots of Black-headed Gulls on the flood water, evidently having just been flushed by a White-tailed Eagle. A Kingfisher flew upriver and several Skylarks flew west. Waltham Brooks was relatively quiet aside from the two Great White Egrets again which circled over the main lake briefly before flying off towards Widney Brooks. Again, several Skylarks flew over and a flock of 17 Redpolls flew over the sewage works. There has been a real absence of winter thrushes the past couple of days, aside from five today over the local farmland.

An evening stroll out to Thorndale Bridge revealed another Great White Egret feeding in a ditch just across the river and a smaller egret species in flight over Amberley Wildbrooks which was probably a Cattle Egret. Two fast flying raptors caught my eye and quickly revealed themselves to be an adult male Merlin being chased by a female. They dashed off low through the trees past Quell Farm at high speed and off towards Parham.
