With May coming to a close, we couldn’t have asked for a better spring in regards to Osprey progress with several new milestones hit. Most importantly we have three new males now present in the harbour area which will be seeking to set up territories of their own in the coming years. Of course theres also been the excitement of a newly arrived female adding to the drama, with reports coming in over the last few days of activity on several publicly visible nest platforms. We therefore felt it was important to provide an accurate update on the situation to avoid any confusion or mis-communication.

On Wednesday 27th of May, a new Scottish ringed female Osprey, ring number 6J8 arrived into the harbour and instantly drew the attention of our male 5R0. The two sat on a harbour nest platform for a few hours, and a fish delivery was even observed. The next morning the two birds were seen again, and some sky dancing was logged, and the male also tried to mate with her, but being as 6J8 is only 2-years old, she refused his advances and he soon gave up. The following day 5R0 had disappeared, but this time male 5H6 paid her a visit, and he too started getting a bit over excited, trying to land on top of her, and was seen carrying a few sticks. After an hour or so of trying to impress her, 5H6 disappeared and 6J8 was once again on her own. Then, the following morning 2 Ospreys were seen again, and upon reviewing our camera footage we could now see our third male Osprey 5H3 was now trying his luck, flapping around her, delivering her a fish and ‘playing piggyback’ (seemingly a popular game with these young lads)!

In summary, over the last 5 days, all three of our males have been interacting with 6J8, which is exactly what we want as this will give her plenty of purpose to return to Poole Harbour next spring. For clarity, no new pairs have formed, and no copulating has taken place. The reports we’ve received of copulating are simply just each of the males trying their luck, but as explained above, 6J8 isn’t in breeding condition, so has refused all of their advances, despite their best efforts of landing on her head and back!!! There’s still a long way to go this summer and A LOT to be sorted out between them all and it’s hoped that 6J8 will spend the whole of the summer and early autumn touring the local area, checking out multiple potential nest sites and making assessments ready for next year, whilst constantly attracting the attention of our three excitable teenagers. Of course, there’s always the chance that other new females may enter the equation, which could spice things up even more. In truth, we won’t really know the outcome of this situation until next spring, but it’s been fun watching and witnessing this new era evolve, and long may it continue.

Elsewhere there were 2 Little Tern, 2 Roseate Tern and 2 Spoonbill on Brownsea today and a White-tailed Eagle flew down Middlebere.

Another stunning day across the harbour with such a stunning variety of species. Best bird of the day was without doubt a stunning adult Black-crowned Night Heron at Little Sea, Studland which was viewable from the Rees Cox Hide pretty much all day. Despite ‘Night Herons’ becoming increasingly regular across many areas of the UK in recent years, they’re still incredibly rare here in Poole Harbour, although it’s possible they could be going ‘under the radar’ due to their skulky, shy behaviour with the ability to hide in scrub and vegetation around the fringes of freshwater bodies. Elsewhere a Honey Buzzard flew straight over Poole Quay at lunchtime, being mobbed by gulls and there was another (minor) push of Red Kite today with 4 heading north over Brownsea and 7 over Studland. Elsewhere there were 5+ Osprey between the Wareham Channel, Lytchett Bay and Middlebere, including female 6J8 catching a fish in Middlebere. On RSPB Arne Moors there were 2 Great White Egret feeding, the local Marsh Harrier pair were at the west end of the Wareham Channel busy visiting their nest site to feed young, local male White-tailed Eagle G463 was in the Wareham Channel all afternoon scoping out his next meal and on the Brownsea Lagoon there was single Spoonbill plus 4 Avocet, 1 Dunlin and multiple Great Black-back Gull families.

Much cooler now, but pleasantly mild and still good birds around the harbour. There were 2 Little Tern that were moving between the Wareham Channel and Middlebere during the course of the day. It was Osprey madness this morning with four different individuals moving around the west of the harbour, local breeding male 022, newly arrived males 5H3 and 5R0 and then newly arrived female 6J8. On Brownsea Sandwich Terns have been hatching for a couple of days and today 2 Common Tern chicks hatched, plus a Spoonbill was on the lagoon. There was another light passage of Red Kite today with 9 north over the harbour mouth, 6 over Studland and 6 over Swineham. This evening 2 Osprey came in off the sea at Kimmeridge within 20 mins of one another. Finally, we were thrilled to see the fourth egg hatch on the Carey Osprey nest this morning which is brilliant news, and a hat-trick as this is now the third year in a row.

The first Sandwich Tern chicks have arrived on Brownsea, with at least eight counted by the DWT team from the Avocet Hide islands this afternoon! And there was also more promising signs from the new Osprey couple in town (2-year olds 6J8 & 5R0) as early pair bonding continues. Highlights from across a relatively quiet day’s birding around the harbour featured a Honey Buzzard drifting over Canford Heath early afternoon and a Little Ringed Plover on Lychett Fields – the latter noteworthy given their near-complete absence at the site this spring. Out of area, but news of a Roller in New Forest might just spark the motivational inspiration needed to stay out and about, scouring those local patches and keep birding through this heat. Meanwhile slightly closer to home, a Bee-eater at over Durlston CP this morning also provided a splash of colour along the Purbecks.

Although things were cooling down today in terms of temperature, things were (potentially) hotting up on the Poole Harbour Osprey scene when around 2pm two Ospreys landed briefly on a harbour nest platform. We were able to read one ring number easily enough which was recently returned male 5R0, but the second, which was obviously a female due to the darker, heavier necklace seemed to be wearing a blue ring on the left leg. After a bit of patience we were finally able to read the ring number as ‘6J8’, which has been traced back to this bird being a 2024 female from central, southern Scotland in the Tweed Valley. This is exactly the scenario we’ve been waiting and hoping for as we now have three available males who are in search for newly arrived females. Now its way too late for them to attempt to breed this season, and both are just 2-years old, however if 5R0 is smart and is able to impress her enough to stay, there’s a chance they could stay around the harbour all summer and adopt a nest platform somewhere which would be great news….lets watch this space. In the mean time, there are still two other males (5H3 and 5H6) that are also seeking out females so if a few more were to turn up, it wouldn’t be a bad thing.

The most random sighting of the day goes to a male Red-breasted Merganser which was feeding on the Brownsea Lagoon this morning. Not so random (but still good) was a single Little Tern also on the Brownsea Lagoon. An adult White-tailed Eagle was in the Wareham Channel this morning as were 2 Osprey and 1 Marsh Harrier. This evening 5 Whimbrel flew over Upton.

Another sweltering day, with most activity once again logged before midday. A morning survey along the River Frome between Wareham and Swineham by local birder Garry Hayman at dawn produced 2 Great White Egret, 1 Cuckoo, 81 Reed Warbler, 18 Cetti’s Warbler, 8 Sedge Warbler and a Yellowhammer (odd Swineham record). Above the thousands of beach goers at Branksome Chine a lone Fulmar was soaring above the beach, an odd place for one to be on a scorching May day, but not as odd as a lone Barnacle Goose that flew over Brownsea this afternoon. This afternoon 2 Osprey were hunting in the Wareham Channel, plus on the Brownsea Lagoon there was summer plumaged Sanderling and Grey Plover. The heatwave also seems to have seen an emergenace of Stag Beetles with good numbers seen in Hamworthy this evening.

Today was definitely a day of two halves…..birdable and not-birdable. By 7am, temperatures were already 15 degrees, but thankfully a light northerly breeze held steady taking the edge of the heat. However, by 12pm it was 28 degrees and things were tough! Even tougher for our Osprey chick number 2 that hatched this afternoon at the peak of the heat at 12:30pm. Things went well though and by late afternoon both were being fed by CJ7 and 022, and the next phase of the Osprey season is now well underway. An odd occurance, especially in 28 degree heat was a dark-bellied Brent Goose that was stying put in Brands Bay where there was a small number of passage waders including Sanderling and Dunlin, some with exceptionally short bills, and small in body structure, suggesting they’re possibly the arctica subspecies which tend to have really short bills and are currently heading up to NE Greenland. Yesterday afternoon a Glossy Ibis was enjoying Lytchett Fields and tonight from our first Puffin Cruise of the year the trip was rewarded with 3 Puffin and 3 Pomarine Skua. There were 2 Cuckoo at Middlebere, 2 Hobby along the Arne Road, 2 over Carey and 2 over Rempstone. A summer plumaged Grey Plover was on the Brownsea Lagoon and this evening an Osprey was fishing in the Wareham Channel.

Well, they weren’t lying about the heatwave were they! Luckily it isn’t boiled eggs we’re discussing this evening, but the exciting news we wait for every single year, which is that today, our first Osprey chick of the 2026 season hatched. Not only that, we think it was a world record breaker in as much that it had barely started chipping out of the egg before all of a sudden it was out and a fully hatched chick had emerged. This first hatching is right on cue (if not several hours early), and paves they way for hopefully the next three to hatch over the coming week. The first feed was at 16:50 and it seemed to get a few fishy chunks down its throat. If you haven’t tuned into our Osprey nest cam before then firstly….what the hell have you been doing for the last 4 years?! and secondly you can watch all the drama (hopefully not too much) unfold live here: https://www.birdsofpooleharbour.co.uk/osprey-news/osprey-webcam-2025-update/

Our second bit of good news is that our new live Swift Nest Cam now has a pair of Swifts back! The first of the pair arrived back over a week ago and was using the box to roost in at night, as we anxiously waited to see if it’s mate would return. There’s definitely been a hold up of Swift, with many sites across the country reporting low numbers and late returners. Thankfully, just as the weather cleared yesterday it allowed an arrival of Swift to reach the UK including the mate of our already present adult. The pair are now back using the box top roost in, and all being well eggs should be laid some time in the coming weeks. We’ve never had a Swift nest cam before, so this is going to be incredibly educational for us too. One of the grim things you’ll notice is the horrid ‘flat fly’ that use Swifts as hosts, and can sometimes be seen crawling around the nest box. A “flat fly” on a Swift is a colloquial term for the Swift lousefly (Crataerina pallida), a species of parasitic, blood-sucking insect. They belong to the louse fly family (Hippoboscidae) and are highly specialised hitchhikers that live almost exclusively in the plumage and nests of Common Swift. Ergh!
