Harbour Update – 02/10/25

Posted on: October 2nd, 2025 by Birds of Poole Harbour

With the weather due to turn tomorrow and over the weekend, there feels like a bit of hope a rare or scarce trans-Atlantic wader or passerine could appear somewhere, but where and what is anyones guess. Poole Harbour has never logged a North American warbler species and in fact has only ever logged 1 North American passerine, which was an American Robin in 1966. So they don’t come around too often, but Pectoral Sandpiper, Western Sandpiper, Stilt and Semipalmated Sandpiper are all (semi) recent finds, and although it feels it’s getting a bit late for a rare wader to appear we’ll never give up hope!

In the mean time 4 Curlew Sandpiper in Middlebere will have to suffice, plus there were 8 Cattle Egret at Holmebridge, a Merlin was at Hartland, 40+ Spoonbill were ion the Brownsea Lagoon, 1 Little Stint was on Lytchett Fields and the autumns first Redwing was sound recorded over Oakdale last night, heralding the start of the final phase of autumn migration.

With the first day of October feeling more like the first day of May, it wasn’t much of a surprise that there weren’t too many new winter arrivals today, however the Black-necked Grebe that arrived in the Wareham Channel on Saturday has found a friend with 2 present today in the same area. The Spoonbill flock remained at 115 today on the Brownsea Lagoon and there were 2 Common Scoter out in Studland Bay off Knoll Beach. With no Osprey sightings for over a week it was good to see one arrive in over Studland bay this morning before it seemed to track over Rempstone towards Arne. There were 2 Wheatear at Greenlands Farm along with 2 Yellowhammer, 5 Lesser Redpoll and 4 Crossbill over there. A Great White Egret was off Ham Common viewpoint and another was at Middlebere. At Lytchett Fields there was singles of Ruff and Little Stint with several Green Sandpiper. A Green Sandpiper was heard over Hatch Pond too.

Blimey! And just like that September was done. What a month its been with a great passage of birds passing through the harbour. The mid-autumn sun smothered the harbour today and even got a few birds singing with multiple Common Chiffchaff in pretty much full song at the PCW Drain this morning, with no less than 40 present in total, along with 10+ Blackcap, 3 Kingfisher and the first 3 migrant Song Thrush of the autumn dropping down from height, into the scrub. In Middlebere this morning there were 6 Curlew Sandpiper, 2 Great White Egret and c150 Avocet, plus a Hen Harrier was logged in the hide diary, but it didn’t state what age or sex. Wheatear have been rather thin on the ground this autumn, so 3 at Greenlands Farm were good today, and with autumn ploughing on, the checking of a few local ‘tins’ over the weekend logged some fresh, juvenile Adder which is always a joy to see. Finally, this evening a new record number of Spoonbill were logged on the Brownsea Lagoon with 115 counted by Brownsea warden Nicki Tutton. What will the harbour total end up being within the next few weeks before some start moving off on the next leg of their migration south?

Harbour Update – 29/09/25

Not as jammed packed today, being a Monday, but still a good range of birds none the less. A Curlew Sandpiper was on the mud off the Houseboats, South Haven this morning where 5 Crossbill and 15 Redpoll tracked north. At the Sunnyside scrape a male Mandarin Duck was enjoying the pools. At Lytchett Bay a 3rd calader year White-tailed Eagle was settled briefly and 2 full adults were seen in and around the Wareham Channel. On Brownsea the Spoonbill flock was back down to 93 again, but several were out on Shipstal, so the 108 were probably all still present and correct. This evening a roost watch at Swineham produced 37 Little Egret and 3 Great White Egret into the roost, plus there were 2 Curlew Sandpiper, 1 Little Stint and 2 Ruff on the Stilt Pools and 5 Curlew Sandpiper were at Middlebere this afternoon on the low-tide. The ringing station in the Lower Piddle Valley saw another massive Chiffchaff day with 205 ringed, plus 1 very late Willow Warbler, 2 late Grasshopper Warbler, 54 Blackcap and the seasons first Lesser Redpoll. Mid-afternoon 2 Marsh Harrier and 2 Red Kite drifted in high over Slepe Heath.

Another fantastic day today, despite the damp start. It was confirmed ‘officially’ thanks to a coordinated count that there are in fact 100+ Spoonbill in the harbour, 108 to be exact with the DWT Brownsea team counting 95 and 13 more being counted from our Autumn Safari which then joined the 95. We believe this is the full harbour total, although for all we know there could also have been one or two hiding in Middlebere, but for now we’ll settle for 108. This isn’t only a Poole Harbour record, but also a Dorset record and we believe the highest count of any Spoonbill flock currently anywhere in the country. Elsewhere 2 Glossy Ibis flew over RSPB Arne Moors this morning, at Swineham there were 3 Little Stint, 2 Ruff and 3 Curlew Sandpiper with another Ruff on Arne Moors and another 2 on the Brownsea Lagoon. Off Swineham Point 2 Spotted Redshank were feeding, 10+ Bearded Tit were in the reedbeds there, he Black-necked Grebe was still in the Wareham Channel and 3 Marsh Harrier were around Giggers Island. There were also 4 dark-bellied Brent Geese that flew over the Wareham Channel just after 9am. A Great White Egret was in the Wareham Channel and another went into roost at Hatch Pond this evening. At Middlebere the 2 Ring Ouzel from yesterday were still there, and a Hobby was still hunting hirundines. At the lower Piddle Valley ringing site 2 tardy Grasshopper Warbler were ringed along with a very late Willow Warbler plus 55 Chiffchaff. The last 7 days has seen a huge push of Common Chiffchaff with the Lower Piddle Valley ringing site ringing a whopping 1074 in just 7 days!

There was a real mix of Summer, Autumn and Winter today and some cracking birds to be seen. With the wind swinging round to the south, it seemed to have halted a whole range of birds in their tracks, making them utilise the harbour for the day. The best of the day included a Short-eared Owl which was getting harassed by a crow along the RSPB Arne shoreline, a Bittern flew across the Stilt Pools at Swineham mid-morning, a Black-necked Grebe was settled in the Wareham Channel, the first dark-bellied Brent Goose of the autumn flew in over Brownsea, there were 3 Little Stint, 3 Curlew Sandpiper and 2 Ruff on the Curlew Pools at Swineham, 2 Great White Egret in Middlebere and it seems as if the Spoonbill flock has now broken 100+ with 93 on the Brownsea Lagoon, and an uncountable flock of c15 at Shipstal Point at the same time. This is certainly the largest group in the UK currently. Other new arrivals included 16 Knot and 5 Grey Plover on the Brownsea Lagoon, both of which hae been notable in their absence the last few weeks plus 1 Curlew Sandpiper, and 2 Ring Ouzel were along the Middlebere track. The Avocet flock on Brownsea is now at about c300, Swallow and House Martin were still moving south during the course of the day, 3 Marsh Harrier were at Swineham and a Merlin was seen at Middlebere.

It almost felt wintery this morning with the cold still conditions seeing many pairs of gloves being deployed for the first time this season. That said, the birding was still great, meaning the cold was just an inconvenient side effect for those that made it out. There were an impressive 10 Glossy Ibis in the harbour today with 9 at Lytchett Fields and 1 in Middlebere. Theres a really good chance this flock size could continue to grow with nearly c1000 across the country currently. Also in Middlebere today were 3 Great White Egret, 1 Osprey, 6 Curlew Sandpiper, 1 White-tailed Eagle and 1 Marsh Harrier. At Swineham 2 Little Stint, 2 Curlew Sandpiper, 1 Ruff and 10 Dunlin were on the Curlew Pools, 3 Marsh Harrier were off Swineham Point and Pintail are now appearing at multiple sites with 18 in Middlebere, 3 in Brands Bay and 10 in Holes Bay. Avocet numbers are also increasing with c400 in Middlebere and 200+ on Brownsea. On Wareham Common 14 Cattle Egret were feeding with the cattle, the Brownsea Lagoon held 82 Spoonbill, and later in the day 27 were on Shipstal.

Harbour Update – 25/09/25

The weather continues to be perfect for new arrivals to travel in from the north, and from this mornings early start Autumn Safari we were once again treated to witnessing species such as Wigeon, Shoveler, Gadwall and sinensis Cormorant all arriving in from high north, whilst at the same time hundreds and eventually thousands of Swallow, House Martin and fewer Sand Martin all gathered in numbers and begin heading north into the wind for the morning phase of their migration. On the low tide this morning 61 Spoonbill were feeding in the Wareham Channel and 3 Marsh Harrier were off Swineham Point. A White-tailed Eagle was sat distantly in a tree out on Keysworth and a Hobby was chasing hirundines high over the Wareham Channel. There were 2 Little Stint on the Swineham Pools, and 93 Spoonbill were counted on the Brownsea Lagoon again. A Great White Egret was on the Holton shoreline and 5 Cattle Egret were at Holmebridge. There are now 7 Glossy Ibis which were out feeding on the Pools Field at Lytchett Bay, plus a Little Stint was out on Lytchett Fields along with a Curlew Sandpiper. At Middlebere 1 Great White Egret was at the top of the channel, a juv-type White-tailed Eagle cruised over. Yesterday 2 Merlin were logged out on Hartland and 12 Marsh Harrier left the west harbour roost. Up on Ballard this morning more vis-mig was underway with 62 Crossbill over, plus 723 Siskin, 2 Yellow Wagtail and thousands of House Martin.

Today a harbour and county record was smashed, with an incredible 94 Spoonbill present in the harbour this morning with 93 on the Brownsea Lagoon and 1 on the pools at Swineham. This beats the previous high total of 85 individuals logged back autumn in 2023. This is a phenomenal count and is possibly only part of the story, as we don’t typically reach the peak number until mid-October, meaning there’s potentially still more to arrive. Will we reach the magic century by the end of September? This increase over the last few decades is down to the recovering populations in mainland Europe and an expanding breeding range on the near continent. The dream is that they’ll eventually start breeding somewhere in Poole Harbour/Dorset, with this summer seeing 5 immature birds over-summer for the first time, which could be a sign of things to come? Yesterdays 6 White-tailed Eagles were still loafing about with 2 in the Wareham Channel, 2 in Brands Bay and 1 even seen almost going wing tip to wing tip with a Paraglider high over Studland golf course this afternoon. A random male Common Scoter was in central harbour, 4+ Marsh Harrier were still active in and around Swineham and there was some more good vis-mig (visible migration) at South Haven, Studland as 450+ Siskin passed over and another good count of Common Chiffchaff were on the move. Martin Adams, who monitors Holes Bay reported that Wigeon numbers have more than doubled overnight to reach 261, joining an impressive 514 Teal. 10 Pintail saw the first double figure count of the autumn, plus 18 Shoveler. Black-tailed Godwit numbers in the NW sector built up with the rising tide to reach 1037, the first 4 figure count of the autumn and Redshank got tantalisingly close to a rare 400+ count, with 397. This evening 4 Glossy Ibis and 1 Curlew Sandpiper were ion Lytchett Fields.

An amazing migration day across the harbour today, with more and more birds arriving from far away lands. Our Autumn Safari Cruise this morning was jam packed with good birds from start to finish. A juvenile Hobby was hunting hirundines over Arne and caught and devoured prey right above the boat at the start of the trip. One of the most amazing finds was a drake Scaup which was settled tight into the reed bed along the Keysworth shoreline in the Wareham Channel. Although distant, 2 Glossy Ibis arrived in from super high above the Purbeck ridge, before gradually dropping into the harbour area and settling on RSPB Arne Moors. A Great White Egret was along the Keysworth shoreline, 4+ Marsh Harrier were quartering over Swineham and Keysworth and a Spoonbill was on the Stilt Pools at Swineham, along with 1 potential Little Stint. The new pools on RSPB Arne Moors are already begining to attract birds with 10+ Dunlin, 2 Green Sandpiper and another potential Little Stint, although these pools are only viewable/accessible from our boat trips. All day thousands of Swallow and House Martin were on the move once again, at times, streaming over in groups of 100+ at a time. On the Brownsea Lagoon 73 Spoonbill were counted, highlighting it’s continued importence as the UK’s most important staging site for this species. Also on the lagoon were 200+ Avocet, 1 Little Stint, 40 Ringed Plover, 100+ Dunlin and 8 Greenshank. There were 2 White-tailed Eagle having a fight over the southern shores of the harbour this morning (resident female G466 and newly arrived 2023 G644), and by this afternoon 6 different individuals were in and around the harbour including 2 new arrivals which were freshly arrived from northern England in the last 24 hours having arrived on the northerly airflow. Wildfowl seemed to be arriving this morning with multiple Wigeon, Gadwall and Shoveler flocks dropping in at various sites. An Osprey was feeding in a tree along the RSPB Arne shoreline in the Wareham Channel and another was cruising around Lytchett Bay this afternoon. This morning the first 2 Lesser Redpoll of the autumn passed over South Haven, Studland along with 248 Siskin. There was another massive Chiffchaff movement across the harbour and this morning a whopping 222 were ringed in the Lower Piddle Valley, along with 69 Blackcap, 3 late Willow Warbler, 2 tardy Grasshopper Warbler, 10 Sedge Warbler and 2 Common Whitethroat.
