17th October

A bit of a soggy one today with super fine rain that never failed to drench any birder who dared venture out into the field. Yesterday's Little Bunting was relocated in the Top Fields feeding away in the drizzle. The rain did not deter some of the commoner migrants with another strong showing from Chaffinches, Linnets, Goldfinches and Skylarks. It was another good day for Black Redstarts with two at the Bill and two near Portland Castle. A Firecrest at the obs and a Goldcrest in Culverwell were the only crests located throughout the day and a single Yellow-browed Warbler was at the Grove.

At least in terms of scarcer immigrant variety/numbers last night was the best mothing night of the year to date, with singles of Maize Moth Spolodea recurvalis and Old World Webworm Hellula undalis the highlights at the Obs:

16th October

On the nicest birding day for some while the middle of the island was veritably hopping with birds, with 5 Yellow-browed Warblers and singles of Ring Ouzel, Siberian Chiffchaff, Firecrest and Hawfinch the pick amongst high counts of a wide variety of thrushes, warblers and finches. The Bill was something of the poor relation but did chip with the rarity of the day when a Little Bunting that appeared over the Crown Estate Field during the afternoon eventually dropped in and was duly trapped there; also at the Bill, 3 Bramblings overhead were the first of the autumn, 500 Swallows and 250 Skylarks were worthy visible passage totals and scarcities included 2 Black  Redstarts, 2 Ring Ouzels and a Yellow-browed Warbler.

Maybe not surprisingly, our crops in the Crown Estate Field have become something of a Little Bunting hotspot in recent years and today we were able to watch the effectiveness of Joe Stockwell's 'ticking bunting' sound-lure that we've employed there in recent late autumns (we knew it was effective because, apart from Little Buntings, we've had the good fortune to stumble across Pine Bunting and Rustic Bunting in nets beside it in the last couple of years!). We happened to be in the field doing a net round when we first heard today's bird calling high overhead and we watched as it did several circuits over the field before plunging into the maize not far from the lure; on this occasion it didn't fly straight into a net but it wasn't long before it made its way toward the lure and was trapped © Martin Cade:  

In much calmer conditions overnight mothing at the Obs was considerably more rewarding than of late, with 2 more Radford's Flame Shoulders the best of the scarcer immigrants. Our highlight though was the long, long overdue first Clifden Nonpareil for the island - not much more than a decade ago this would have been a noteworthy capture anywhere but such has been the remarkable change in their status that, latterly, Portland has been one of the few regularly trapped sites in Dorset not to have had a record © Martin Cade:

15th October

Today finally felt like a traditional autumn, cold, wet and breezy with bushes full of birds and a feeling of potential. Although the 'biggie' never materialized there was a good amount of variety and numbers of common migrants. Blackcaps were the most common migrants of the day with just under 200 individuals recorded; Chaffinches put in their highest count of the autumn with 80 birds around the bill area and Swallows had a late flurry with 104 birds over the East Cliffs. On the more unusual front there were three Yellow-browed Warblers (2 at the obs and 1 at thumb lane), the first double figure count of Reed Buntings of the autumn, 6 Ring Ouzels, 3 Black Redstarts and a lone Mute Swan. In the theme of the past few days we also witnessed some migrants slightly on the tardy side including 4 Swifts, 2 Whitethroats and a Common Sandpiper.

Linnets provided the biggest spectacle of the day with estimates of around 3,000 birds cumulatively in the Crown Estate and the top fields © Martin Cade

The recent spell of exceptionally mild weather that now looks to be behind us had huge potential on the moth front but, since it remained ragingly windy throughout, will chiefly be remembered by us as something of a damp squib. A few routine southern scarcities - Olive-tree Pearls, Vestals, Gems and the like - put in appearances but the killer rarities remained stubbornly absent from our traps. Despite a huge dip in the overnight temperature there were still a few morsels of interest on the wing last night, including the fifth - and least rubbed so far - Radford's Flame Shoulder of the autumn © Martin Cade: 

14th October

An erratic day of weather with heavy showers for most of the morning hampering most birding efforts. As the rain cleared, however, some birds were noticeably moving and in some good numbers. Counts of Blackcap and Chiffchaffs neared 100, Chaffinches were also more evident with 47 birds in total. Phylloscopus warblers were prominent within the obs garden and amongst the flitting Chiffchaff flocks lingered a pair of unringed Yellow-browed Warblers (another bird was also recorded at Wakeham). The Cetti's Warbler frequenting Culverwell was still present this morning along with a lone Firecrest, a pair of Goldcrests and a Snipe.

Ferrybridge was back on form this afternoon with 82 Brent Geese (including a pale-bellied individual), 270 Mediterranean Gulls, 14 Turnstone, 7 Ringed Plover, 42 Dunlin and singles of Oystercatcher and Bar-tailed Godwit. 

13th October

Another warm but blustery day yielded slightly more in the way of migrant activities with a pair of Merlin at the Bill, the loitering Yellow-browed Warbler and Firecrest in the obs garden and the fourth Cetti's Warbler of the autumn making it the best year on record. A few late-ish migrants included a Yellow Wagtail on the West Cliffs, three Whinchats (including two at Avalanche Hump), and a lone Wheatear. The first Purple Sandpiper for some time, a pair of Snipe and a Song Thrush were indicators of how far through the autumn we have already progressed. The sea had only a Bonxie to offer, however this is unsurprising given the huge swell that has been generated over the past couple of days.

With migrant activity at such a low ebb by day it was interesting to receive Nick Hopper's report on his visit to try some nocturnal recording a couple of night's ago (10th/11th October). It turned out to a well-chosen night since the blasting wind that was such a feature of the latter half of the week dropped away to virtually nothing for several hours during the evening and passage was immediately audible over the Obs. Nick's report is as follows:

The night’s recording coincided with a big Song Thrush movement, with 1576 calls logged. The majority of these were in a 3.5 hour period up until around 00.30, after which the calling reduced significantly. A few Redwing also on the move with 108 calls logged and 4 Blackbird.
In terms of rarity value the night’s highlight was the first Firecrest to be recorded since recording began here. In fact 3 individuals were logged during the night. Also 2 Goldcrest. 
Best of the rest: Common Scoter - small party, Common Snipe 2, Robin 5, Dunlin 1, Ringed Plover 4, Grey Heron 1.

12th October

Portland didn't fare nearly as badly on the weather front as points westward but it was still way too windy for any serious coverage of the land and too blown out to have expected much reward from the sea. The Yellow-browed Warbler remained at the Obs although getting any more than a glimpse of it required considerable perseverance; the land returned precious little else bar a lingering a Firecrest also still at the Obs. The sea got plenty of attention but 3 Balearic Shearwaters, a Sooty Shearwater and a Great Skua were as good as it got at the Bill.

11th October

A day of variety if not rarity value. A Yellow-browed Warbler trapped at the obs during a break in the weather provided some much needed enthusiasm during a rather wet an windy morning. A Great Northern Diver was the first of the autumn, a pair of Yellowhammers were a welcome addition to the year list, three Ring Ouzels were present across the island and a couple of Firecrests finalised the less common species. Commoner migrants included: the first 1000+ day of Linnets for the autumn, a small handful of Song Thrushes and Redwings, a Whinchat at Barleycrates Lane, a Snipe at the North end and an Osprey over the West Cliffs.

10th October

Another breezy and stunningly clear day saw a couple of much desired migrants gracing our shores. A Yellow-browed Warbler at both Southwell school and Thumb Lane were accompanied by a lone Firecrest at the Obs, a Ring Ouzel in the hut fields and a Black Redstart in the front garden. The supporting cast of 13 Wheatears, a Whinchat, a Jack Snipe and a pair of Merlins were also of note. Thrushes continued to trickle through with a slack handful of Song Thrushes and a flock of 10 Redwings. Alba Wagtail and Meadow Pipit migration was much reduced on recent days although small groups continued to move throughout the morning.

Over the past few days we have been treated to a wide variety of 'alba' Wagtails, with 'Pieds' now vastly outnumbering the White Wagtails we saw passing earlier in the season © Erin Taylor 

...and how tricky can some of them be? © Martin Cade 

Unfortunately, it still hasn't really been happening on the moth front, with the much-vaunted warm spell failing - at least so far - to produce the immigrant goods. Another Radford's Flame Shoulder - the fourth of the last fortnight has been the pick of the oddities, with immigrants otherwise in unexceptional numbers. As much if not more interest has come from the variety and numbers of unseasonable species putting in appearances in the traps; most have appeared on odd occasions at this time of year at some time in the past but a few such as this Chalk Carpet a couple of morning's ago look to be entirely unprecedented for October © Martin Cade:

9th October

Although it was a pleasure to out in summer-like conditions numbers and quality were at a premium today. The only oddity reported was a Yellow-browed Warbler near the Borstal, with the less regulars list including the likes of 2 Merlins, a Ring Ouzel and a Firecrest at the Bill and the first Black Redstart of the autumn at Blacknor. Although the conditions were far too nice to have expected any sort of arrival on the ground it was also surprisingly uneventful overhead where standard mid-October fare was reduced to a trickle and only 24 Siskins over the Obs merited a mention; the fact that there were, for example, fewer than 10 Chiffchaffs at the Bill just about summed up the general dearth of grounded migrants.

So gloriously warm and sunny was it that without making any particular effort 12 butterfly species were logged around the island today; these included Clouded Yellows dotted about at several sites, a Brimstone (a decent island oddity) at Tout/Inmosthay and an Adonis Blue still on the wing there. Common Blue and Small Copper were among the more expected fare enjoying the conditions

8th October

A quite different sort of day to yesterday saw heavy cloud overhead for the duration and Pied Wagtails, Meadow Pipits, thrushes and finches to the fore on the migrant numbers front. Another Yellow-browed Warbler - this one at Southwell - was the best of the oddities, with the first Ring Ouzel of the autumn at the Bill, a Dartford Warbler at Suckthumb and a Green Sandpiper at Broadcroft  of further note. Numbers-wise, it was visible migrants that dominated, with 1500 Linnets, 1000 Meadow Pipits, 360 alba wagtails and 250 Goldfinches tip-of-the-iceberg totals at the Bill where far more birds on the move way out over the sea had to be left unidentified. On the ground, thrushes were quite conspicuous for the first time this autumn, off-passage flocks of Meadow Pipit and Linnet totalled into four figures at the Bill and Blackcaps were numerous around the centre of the island but the like of Chiffchaff hardly featured.

Today saw the commencement of the inter-bird observatories bird race and as such we can tell you that an average to poor day on Portland Bill will earn you a species list of around 80 birds. The morning started with a flurry of common migrants with 44 Chiffchaffs trapped and large flocks of Siskins and Pied Wagtails overhead. Highlights of the day included: the first Yellow-browed Warblers of the year, a pair of obliging Woodlarks at Shepherds Dinner (I didn't know that was a place either), the first Redwings and Fieldfares of the autumn and the third Cetti's Warbler of the autumn.

6th October

No matter how much effort we put in today the elusive Yellow-browed Warbler never showed, probably due to the howling gale and thrashing rain. Other than a pair of Brent Geese heading west and 15 Golden Plovers overhead, variety was mostly confined to those migrants who didn't leave before the onslaught of the weather. A small flock of 12 House Martins marked the beginning of the end of the Hirundine movement for the year.

5th October

If we'd have known just how many thrushes and Robins had been passing over during the hours of darkness - overnight recordings later revealed a steady passage that included the first Redwings of the autumn - we might have been even more geared up for the day that we were at dawn when it soon apparent that there were plenty of Chiffchaffs and Blackcaps about at the Obs. Sadly, however, it proved to be one of those days when pretty well everything left as soon as the sun got up and later toil turned up nothing in numbers and, the lingering Moorfield Road Hoopoe aside, nothing of quality. The hitherto also lingering Turtle Dove at Culverwell only showed once at dawn , with 3 Snipe were the only other even faintly less regular migrants to report from the Bill. Elsewhere, 2 Redstarts were at Wakeham and another Snipe passed over at the Grove. The only sea news was of a lone Balearic Shearwater through off the Bill.

Despite another impressive large catch of moths at all sites immigrants remained rather less numerous as might have been hoped given the conditions, with singles of Gem and White-speck the best of the scarcities at the Obs.

4th October

Heavy cloud, a drop in temperature and a change in wind direction had everyone scouting for a rare. Unfortunately the only uncommon species we were treated to were the long staying Turtle Dove and the equally obliging Hoopoe. Today saw a second consecutive increase in Blackbird numbers along with the first couple of Song Thrushes. The most numerous migrants within the obs garden were undoubtedly the Chiffchaffs with 36 trapped throughout the day and dozens more recorded across the island, our first Phyllosc fall of the autumn. A Tree Pipit over the 'Hoopoe paddocks' was potentially the last of the year and three Great Spotted Woodpeckers was the highest day count of the year. Other than this, migration trudged by as normal with only the commonest fly-over migrants putting in any big numbers.

3rd October

Another October scorcher saw little in the way of rare migrants but large numbers of common passage birds kept everyone counting through the morning. A minimum tally of 450 Meadow Pipits were matched for the first time this autumn by passing Alba Wagtails. Chaffinch, Siskin and Reed Buntings continued in numbers and the first signs of thrush passage began with an increase in Blackbird numbers in the top fields. The highlight of the day came from the return of the Hoopoe to the horse paddocks in Easton, whilst nearby there were 2 Firecrests at the Grove.

2nd October

A brisk and cloudy morning soon evaporated into somewhat of a stunner where weather was concerned. Avian highlights included the second Cetti's Warbler of the autumn trapped in Culverwell, 36 Brent Geese East past the Bill and a Merlin in the top fields. Otherwise, the movement that has brought Hoopoe and Wryneck to our shores in recent days seems to have slowed up and only a handful of other commoner migrants were recorded throughout the day.

1st October

A fair spread of birds again today with a Hoopoe in the Moorfield Road horse paddocks stealing the show rarity-wise; yesterday's Turtle Dove was still at the Bill, with a second individual also dropping in at Moorfield Road, whilst among the less regulars there were 3 Great Crested Grebes, 2 Merlins and singles of Mallard, Golden Plover, Yellow-legged Gull and Great Spotted Woodpecker at the Bill and at least 1 more Great Spotted Woodpecker at Easton. The slight improvement in common migrant numbers detected yesterday was maintained, with both Blackcap and Chiffchaff around the 40 mark at the Bill.

Overnight immigrant moth interest included another Radford's Flame Shoulder at the Obs (the third there in recent nights) and the year's first Vestal at the Grove.

Searches for yesterday's Wryneck drew a blank on that front but did turn up this Hoopoe in an adjacent horse paddock:  

Linnet numbers are beginning to build and with any luck good-sized flocks should become a familiar sight around the island for the next few weeks; this group were some of the 100 in the Crown Estate Field and another 300 or more were knocking about around Helen's Fields:

It's been a good year for seeing Bottle-nosed Dolphins off the Bill: the crew of this plush yacht were treated to what must have been great views of today's party bow-riding alongside the vessel as it headed along East Cliffs this morning:

It's fortunate that Vestals have a highly characteristic jizz as last night's first for the year was somewhat scale-deficient:

Come the totting up for the year we'd be surprised if it isn't by far the best season ever for Gold Spot at Portland; the first for the year just sneaked in at the end of May so a single at the Grove last night was not only the first for several weeks but also ensured that we have records from six months of this year photos and video © Martin Cade:

30th September

Hardly a day to remember but there were encouraging hints of passage picking up just a little, most notably in the form a decent spread of Chiffchaffs just about everywhere. A Wryneck at Easton was as good as it got in the scarcity line although in this day and age a Turtle Dove at the Bill was of almost the same status. The Chiffchaff tally at the Bill reached a good 50, with plenty more in most areas of cover around the centre of the island; at least new Great Spotted Woodpeckers pitched in at the Bill but, bar the now ubiquitous flocks of off-passage Meadow Pipits, there were no other notable concentrations of grounded migrants. Visible passage of Meadow Pipits, Chaffinches and Siskins got off to a good start in the clear skies after dawn but fizzled out as soon as thick cloud rolled in from the north before mid-morning.

Although we're always quick to deride the national news services for putting out reports of the likes of single Black Redstarts and Firecrests from southern coastal headlands - since when have they been even faintly unexpected migrants anywhere other than at places that don't get any birds anyway? - we can certainly understand why every migrant Turtle Dove is now being reported. The writer of these notes dipped this one and still hasn't seen one at Portland this year - his memories of flushing flocks of 50 in Top Fields when he was a kid are also getting hazier by the year © Roger Hewitt: 

Considering the dearth of grounded migrants generally, Spotted Flycatchers have been surprisingly conspicuous at the Obs, albeit only in low numbers; this one was there a couple of days go © Dave Sawyer: 

29th September

Plenty more gripes about the general dearth of migrants today: visible passage continued to tick over although was hardly spectacular but it was island-wide paucity of the likes of Chiffchaffs that drew the most comment. A Cattle Egret that arrived in off the sea at the Bill and continued rapidly northwards was a nice island rarity, whilst a small flurry of Firecrests - including 4 at Avalanche Road - was a welcome event. Stonechats are beginning to feature in some quantity, with 35 scattered between the Bill and Barleycrates Lane, but few if any of the other grounded totals were worthy of a mention. Most of the usual suspects were represented overhead but numbers were on the low side for a seemingly suitable clear day and single Hobbys over the Bill and Avalanche Road were the only oddities. Additionally, 2 Brent Geese and an Arctic Skua passed through off the Bill and 2 Knot were at Ferrybridge.

Another Radford's Flame Shoulder was the pick of the immigrant moths trapped overnight at the Obs.

28th September

It'd be pushing it to say that there were high expectations for today but with a fresh north-easterly having sprung up overnight as a weak weather front arrived from the north there was at least some hope that grounded migrant numbers might pick up; in the event, cloud cover didn't arrive until well after dawn and it was as quiet on the ground as it had been for the rest of the week. A Common Rosefinch that dropped into a mist-net in the Crown Estate Field certainly wasn't to be sniffed at, but quality didn't otherwise get beyond an Osprey over Ferrybridge. A strong visible passage for the first few hours of the morning took place on such a broad front that it was tricky to quantify, but sample totals at the Obs included >1000 hirundines, 550 Meadow Pipits, 100 alba wagtails and 46 Siskins. Bitsy interest on the sea included singles of Manx Shearwater, Balearic Shearwater, Arctic Skua and Great Skua through off the Bill.

27th September

This week's run of crystal clear, full moon nights and cloudless, increasingly hot days have been just what the migrants ordered for trouble-free departures from our shores but the birders have been left scratching around with no more than scraps of interest to keep them entertained. The first Woodlark of the autumn was today's highlight at the Bill, where Swallow, House Martin, Meadow Pipit and Pied Wagtail all featured in mid three figure totals overhead. The overwhelming bulk of the numbers of just about everything were overhead, with 50 Skylarks and 22 Siskins further noteworthy totals at the Bill, where 42 Blackcaps was the only worthwhile grounded total. Reports from elsewhere included a presumed Nightingale glimpsed briefly near Nichodemus Knob.

A Radford's Flame Shoulder was the pick of the overnight moth catch at the Obs.

26th September

A blistering sunshine filled day came up with an early highlight in the form of a Caspian Gull that spent a few minutes in the fields along East Cliffs. A brief pause in the Meadow Pipit passage we have been experiencing was soon evident but the hirundines, wagtails and finches remained true to their usual form and put in a strong showing, including 42 Siskins over the obs. Reed Buntings are also becoming a frequent addition to the day tallies as the autumn draws on. A Tree Sparrow added some much needed variety to the proceedings but it was the Hirundines that stole the show with a monumental passage of Swallows and House Martins with a few Sand Martins tagging along for the ride.

25th September

Dawn offered up perfect migration conditions - crisp and clear in a gentle north-easterly - and four figure totals of Meadow Pipit and Swallow were racked up in very quick time; however, with the notable exception of yesterday's likely Monarch butterfly being fully confirmed and a typically out-of-the-blue Cetti's Warbler dropping into a mist-net the day otherwise proved to be a little bit of an anti-climax, with precious little grounded in any quantity. The Bill area Swallow and Meadow Pipit totals reached 5000 and 1000 respectively, with further reports of many thousands of the former from several sites around the north of the island. Most of the other mid-season visible migrants were well represented, with a new Great Spotted Woodpecker and an early-ish Mistle Thrush the best on offer at the Bill. Despite the benign conditions the sea came up with a few surprises including 72 Common Scoter, 4 Great Skuas, 2 Arctic Skuas and the first Dark-bellied Brent Goose of the season through off the Bill.

A small influx of immigrant lepidoptera included 6 Clouded Yellows and an obvious increase in Red Admirals around the south of the island, along with the first White-speck of the season from the Obs moth-traps; the first Convolvulus Hawkmoth for over a week was also visiting Nicotiana flowers at the Grove after dark.

Yesterday's presumed Monarch was fully confirmed once it surfaced for a while in the Obs garden as the temperature started to creep up from an overnight single figure low; sadly it hardly looked to be thriving - quite apart from being very battered - and after a few seemingly weak flights and the odd bit of basking it vanished © Martin Cade:
