To me Spring isn't 'real' until I hear and see the Tree Swallows zooming around the garden. This morning I had one of the early scouts checking out the nesting boxes and it brought and instant smile to my dial. Soon the battle for housing will begin between the Blue birds and the Tree Swallows. The Blue birds will definitely take one house, while the Tree Swallows will take the other two.
What signals Spring for you?
