I rarely see Tennessee Warblers in the Spring but happily see quite a few of them in the Fall. Most of them fly across the Gulf of Mexico to get to their wintering grounds. Safe travel little birdies!

Over the moon (to put it mildly) to find this first year male SIBERIAN BLUE ROBIN in our garden at Hillwell, Shetland this morning. The fifth record for Britain and a first for Shetland. #BirdingScotland #UKbirding #RareBirdsUK #Birds #UKWildlife

Only 20 moths of 14 sp last night despite the mild and cloudy weather. However, Blair’s Shoulder-knot and Rhomboid Tortrix were nfy, Pink-barred Sallow provided some colour and a late Box-tree Moth is maybe a 2nd generation one. #TeamMoth @teesbirds.bsky.social

My morning walk on coast didn’t result in any good finds, so a bit of afternoon twitching thanks to a Corncrake found by @mickthebirder71.bsky.social in Seaham was very welcome. Everyone present got brief but good flight views after 4 pm - a nice county ✅ for me. #NEbirding @teesbirds.bsky.social

Coming soon to the UK... If you're a gambler, the smart money is on the impending appearance of a Nutcracker on our shores. By way of pre-emptive celebs, here's the two outrageous individuals that were part of my youth ~ Westleton November 1985 & Cocknage Wood, October 1991. Epic rare! #rarebirdsuk
1985 was a stunning year of rare bird chasing for me. One of only two occasions I hit the magic 300 mark for the yearlist and, within them, some truly outstanding birds, including one or two that still haven't "come back" (hello Little Whimbrel 👋). The autumn of 1985 was crammed full of new birds for me. A host of rarities around Scilly was followed by some tremendous long weekends bunking off school for twitches to East Anglia. The Westleton Nutcracker was supplemented by  Long-billed Dowitcher, Rough-legged Buzzard, Grey Phalarope & more...(another weekend would produce the famous How Hill Black-and-white Warbler plus Snow Goose, White-tailed Eagle and - again - more! There was a Pied Wheatear in there too somewhere... This absolute character gave ludicrous views on the edge of Stoke-on-Trent through October 1991. I think I was looking at the board of the Porthcressa when it was written large on the blackboard. My erstwhile companion, Graham Etherington, was a Stoke boy and he couldn't quite believe it...
We came off Scilly for the Flamborough Desert Warbler and took in a visit to Cocknage Wood (and Graham's mum!) and were blown away by the fearless spotty one...somewhere there is a photo of me and the bird, side by side, one of us mugging off for the camera 😂

I'm not sure if it was a fish or a frog that this Green Heron spotted, but it was something exciting enough to make the bird go into mohawk mode.

Radar image of Tuesday's mass crane migration. A 100 km long line of migrating cranes was clearly visible on weather radar. It is estimated that around 10,000 (?) cranes were involved in that formation. The highest count observed was 26,000 migrating cranes on that day in Kangasala (near Tampere).

Always stay alert… Walking past some ivy on a southeast London street. My subconscious discerns a micromoth fizzing. Turns out to be Clepsis dumicolana. Turns out there are a dozen. Relatively recent, ivy-feeding colonist. And new for me.
