Seeing Purple Sandpipers on their breeding grounds was top motivation for #Svalbard - love these little guys and often wonder where they go after UK winter. Honoured to see ~20 & found one with 4 chicks on final day! Mission accomplished 👍. Hope they survived the Arctic Skuas 😬

Lunar eclipse from last Friday, 28/8/26. Didn’t realise solar and lunar eclipses usually come in pairs: solar eclipse at new moon as the Moon’s shadow is cast onto Earth; lunar eclipse at full moon as the Earth’s shadow is cast onto the Moon. Syzygetic! 🧐

Another fab ringing story. Spotted this Long-tailed Skua nr Ny-London (79°N); a study bird for the Norwegian Inst. Nature Research (Gilg et al 2013). Geolocators show wintering near S Africa (35°S), travelling 44-54,200 km per year! Think this bird is 16 yo = ~0.8 million km! 🤯
Love getting ringing histories back. Meet ‘DSJ’, ringed in Ny-Alesund as gosling 7/24 (79°N). Wintered on the Solway 2/25 & nr Caerlaverock 1/26 (55°N). Seen in Longyearbyen 7/26 (78°N). That’s a 1700 mile commute, so this 2yo female has already racked up >7000 miles! Awesome 🙌
My efforts on the long-staying Long-tailed Shrike. Great to watch it catching various insects. Family of Grey Partridge nearby too. #GlosBirds

Think autumn migration starts in September? Or that a 14km sea crossing is easy for raptors? 🦅❌
