Autumn/Winter Migration is hot topic right now in the Uk because Birds that I've already mentioned in previous blogs like Redwing, Fieldfare and Brambling have all come from up north from countries like Scandinavia.
Birds don't always migrate across the sea though as some of our native breeding birds remain in the Uk but still move south or to the coast-line. This is called local migration and for some birds like Redpoll, local migration is really important. On our very own coastline of the Gwent Levels, you can expect to see a lot more Redpoll turning up to feed on various seeds that autumn provides in our coastal plants. Redpoll will often stick in flocks this time of year (like many other species) and throughout winter, the seeds in which they seek are often in open areas which exposes them to predators like the Sparrowhawk.
Stonechat's are another species that end up in random places along the coast and despite some birds actually breeding along the coast line in spring, most have travelled from our uplands.
Moving down in altitude can make all the difference to survive our cold winters.
