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!

Well, the sun we’ve all been promised finally arrived today and as a result temperatures soared. Despite the overcast start to the day, the low cloud soon cleared and the Bank Holiday mega weather weekend started early. Weirdly, the fist bird of the day was a Red-throated Diver that flew over Arne just after dawn, suggesting it had been blown in in recent days and was now off with the improved weather window. This morning 2 Osprey were in the Wareham Channel, including male 022 catching just off Giggers Island. With the new RSPB Arne Moors project now well into it’s completion phase it’s interesting to note it really seems to be benefiting Shelduck already, with several hundred having been seen gathering there recently and today in the Wareham Channel there was a single flock of 204 which is pretty high for late May. At Durlston this AM, a potential male Red-footed Falcon was seen heading north which if it was could easily end up in the harbour or Wareham Forest/Morden Bog, so well worth double checking any Hobby you’re watching ove rthe harbour skylines. This would be an addition bird to the one thats currently north of Wimborne at Holt Heath.

Another windy, blowy day with a short focus on the sea this morning which didn’t yield much other than 20+ Gannet, c50 Sandwich Tern, c30 Common Tern and 5 Mediterranean Gull. However all three hirundine species (House Martin, Sand Martin and Swallow) were all logged coming in off the sea highlighting that migration is still underway, plus 8 Swift also came ‘in off’. This afternoon our new Osprey arrival ‘5H6’ (aka the Mighty Titch) visited a harbour nest platform.

Another windy,

A blustery day making birding difficult, but 2 Little Tern in the Wareham Channel today was a good reward, also 2 Osprey in the Wareham Channel,  several parties of Swift were over Swineham, 9 Avocet were on the Brownsea Lagoon, a 2nd cal year Kittiwake was in central harbour, plus 2 random Wigeon were on the Brownsea Lagoon this morning, also 7 Avocet including what looked like a couple ‘sitting’ individuals which would be great news for the island. A Whimbrel was on the Brownsea north shore, c150 Dunlin were settled on Shag Looe Bar, the Wareham Channel and 3 Gannet were near the harbour mouth.

Also, there was a positive update from Dorset Wildlife Trust volunteer Martin Adams providing an update on the Brownsea Lagoon terns: Encouraging signs with 106 Common Terns sitting (up from 68 on Friday,) 81 Sandwich Terns (up from 55,) and 87 Black-headed Gulls (up from 66) with 21 chicks now. The Black-headed Gulls have returned to the tern islands in small numbers where there were hardly any on Friday. 10 Great Black Backed Gulls on nests.
