Our Siskin population is boosted by migrants during the winter months. The migrants, and the native populations can be seen feeding on their favourite conifer, Alder and Birch seeds but are increasingly taking to peanuts and seeds from feeders in gardens, like these in Pitsmoor today. Siskins are predominantly olive green and citrus yellow, and are smaller, and more streakily marked than the two finches you could, at first glance, confuse them with – Greenfinch and Goldfinch. Conditions: Icy and blue-skied following the coldest night of the year so far. Temperature: Max 2- Min tonight, 1C.
