Polarised Light
The Swallows have arrived!!! We saw the first ones this year earlier thia week! It was so wonderful to see these amazing birds!!! They have come a long way!!! All the way from South Africa Incredible!!! Unlike most songbird migrants, swallows fly by day, feeding on small flying insects as they go. They navigate using the Earth's magnetic field, polarised light and visual landmarks. #swallowsmigration #swallowmigration #swallowsart #swallows #swallowfacts #swallows #birds #swallowsofinsta...
