If you said swallows, you’d be largely right. Park Ridge will never be confused for San Juan Capistrano, but the swallows have indeed returned to Electric Lake and can be seen in good numbers. So far I’ve been able to photograph three types of swallows swooping, dipping and diving over the lake.
Northern Rough Winged Swallows
In addition to the insects the swallows are intercepting in the air, they are also picking them up off of the surface of the water.
If you are near some of the shrub growth or trees you will also see Eastern Phoebes making runs over the water to catch insects. Here one is taking a break on a rock.
