Although some Eastern Bluebirds continued their presence in the park during this past very cold winter, there is increased activity as of late and it's quite possible that some Eastern Bluebirds have returned from a short-distance migration. If you are in the park, watch for the bluebirds which have recently been seen perching on the fences and flying around the nest boxes.
Today brought the first sighting of Tree Swallows in the park. These acrobatic flyers are already reducing the local insect population and will continue to do so from dawn 'til dusk until they leave again in late summer. These birds have recently returned from as far away as southern Central America. Watch for their acrobatic flights over the cattails and ballfields. They will likely also begin to check out the nest boxes shortly.
