A Week on the Estate: Counting Sparrows, Compo’s Mitts & Squire Remembered
Next Tuesday, 21st December, marks the winter solstice with a mere 7.5 hours of daylight at our latitude. From Wednesday, the days will begin to get longer and brighter again. After a well-earned Christmas break, we’ll be ready for all the hard work and success that 2022 brings.
We’re hugely grateful to Richard Doan and Lincolnshire Birding on Twitter. Richard took a walk around the Estate on the Railway Tavern Trail and counted: “400 fieldfare, 80 redwing, 42 blackbird, 80 yellowhammer, 150+ tree sparrow (!), 1,200 linnet, 10 brambling, water rail & 8 bullfinch”. This is all excellent news but we’re especially chuffed about the tree sparrows.
The Eurasian tree sparrow (Passer montanus) used to be a common sight in the British countryside but its numbers declined by an estimated 93% between 1970 and 2008. Intensified agriculture, with insecticide and pesticide use and fewer stubble fields and insect-rich wetlands, made it tricky for tree sparrows to survive winter.
The RSPB estimates the tree sparrow’s UK population to be 200,000 pairs, comparing poorly with the house sparrow (Passer domesticus) at 5.3 million pairs. We’ve been working hard to improve this with regenerative practices, more hedgerows, wildlife-friendly field margins and nesting boxes (thanks to the Saturday Club). Richard’s count made our week.
