Tree Swallow checking out the house! "Handsome aerialists with deep-blue iridescent backs and clean white fronts, Tree Swallows are a familiar sight in summer fields and wetlands across northern North America. They chase after flying insects with acrobatic twists and turns, their steely blue-green feathers flashing in the sunlight. Tree Swallows nest in tree cavities; they also readily take up residence in nest boxes." - www.allaboutbirds.org | Critter Cam

If you’ve ever tried to track an acrobatic Tree Swallow with binoculars, you can appreciate their incredible agility and speed. So imagine how tough it might be to capture them on film! But not only do Tim and Russell Laman capture them in their lenses, they slow down the action so we can see every adjustment in every wingbeat. You don’t have to get dizzy trying to see these insect-loving birds. We take you up close—even inside a nest—in Episode 2 of our series Wild Birds Revealed. Watch the bus
