Spring is not complete without the arrival of swallows. I saw the first Tree Swallows already a couple weeks ago but now we can find them in large numbers. I spent most of the day in the Green Island Wetlands. This dead tree is standing in the water and was used by the swallows as a place to rest. There were moments when all of them took off, catching insects in flight, but after a while they always came back to this tree. The Green Island Wetlands are an ideal habitat for these swallows. There is food in abundance and many dead trees, with cavities or woodpecker holes, provide the nesting places for them.
