Swallows at Wood Lake Nature Center

There always seems to be a healthy population of swallows at Wood Lake Nature Center during the warmer months of the year.
Barn swallows, like the one pictured above, can often be seen circling around the visitors center. They build their nests in the eaves and other nooks and crannies of the building.
Tree swallows, like this one, are more often found on the other end of the park. They prefer to nest in the bluebird boxes which are placed in the open fields on the west side of the park.
Both types of swallows will often perch on the cables, which serve as a railing for the boardwalk which runs across the lake in the middle of the park. From their perch, over the water, they can easily take off and catch flying insects as they pass by, which is their main source of food.
