Any birding plumbers out there who can advise please? We have oil central heating via a combi boiler. There has been a burst main in a field nearby so our water is off. Can we still use the heating tonight? Google gives conflicting replies? Cheers

Ostriches, emus and other flightless birds weren’t always grounded. 56 million years ago, their ancestors were globe-trotting fliers capable of crossing oceans – and one fossil bone helps explain how this (mostly) flightless family spread across the world.

Sunny day walking from Blackhall Rocks to Castle Eden Dene, but not many birds around. 62 P-f Geese, 6 Chiffchaffs, 5 Stonechats, R-t Diver and 10 Tree Sparrows were the highlights, so we were distracted to harvest some sloes for sloe gin 🍷.

Surprised to find a Light Emerald on the moth sheet last night as we do not usually get 2nd generation up here. Pale Mottled Willow was a year ✅ (due to being away large part of July). Also, 5 Red-green Carpets and a Dark Sword-grass. Durham VC66.

Baltic Gull (juv) vs Caspian Gull (juv). Compare and contrast. There are times actually where juv Baltics can approach the appearance of Caspian (though Baltic always feels dinkier). But there is this coldness & contrast to Baltics that always strikes me.

Curlew Sandpiper influx is biggest in years
A major influx of Curlew Sandpiper has taken place across Britain and Ireland during September 2025, with the arrival considered the most significant for many years. The influx is thought to have involved thousands of birds, with three-figure counts made at some sites and several more totals in excess of 50 individuals. While historically Curlew Sandpiper was much more common on migration in Britain and Ireland, this year's influx is of great significance by modern standards.

While I was cleaning up the moth trap this morning a male southern small white was already flying around in the garden. See how the discal spot touches the surrounding veins over a few mm, in male small white this spot is smaller and does not or only barely touch the veins.

Birders record Jerdon's Courser 16 years after last sighting
The Critically Endangered Jerdon's Courser has been rediscovered in Andhra Pradesh, India, outside its known range for the first time in 125 years. Thought to survive only in a tiny patch of the Lankamalla hills, the elusive bird was detected through acoustic recordings by a team of birders in August 2025. The find provides fresh hope for the species, ranked among the world’s top ten 'lost birds', and highlights the urgent need to safeguard India's remaining scrubland habitats.
