The intervals between vocalizations are intact, but I needed to employ equalization by reducing everything 500 and 5K hertz, and then a judicious amount of noise reduction. The Mississippi Kite makes a streamlined silhouette as it careens through the sky on the hunt for small prey, or dive-bombs intruders that come too close to its nest tree. Consequently this recording needed to be cleaned up. directed elsewhere it picks up background ambient 'noise' and carries a metallic signature. MISSISSIPPI KITES The bird predator most commonly heard calling above us is the Red-shouldered Hawk, but nearly every morning another species appears. I built the unit to use for night migrants from the roof of my house. The The pick-up is a very small Senal CL-6 omni lapel microphone suspended inside a plastic tube drilled out as an interference tube. In recent decades, it has increased greatly in numbers and spread into many new areas. I pointed a 24 inch aluminum parabolic microphone in the approximate direction of the birds. As recently as the 1940s, this graceful hawk was considered rare and endangered in North America, restricted to a few sites in California and Texas. This one note call is something I do not remember hearing in the past, but I hesitate to ascribe it to a juvenile bird. The birds are present throughout Altus Air. Since migration for this species is only a few weeks away (mid-August) I am assuming that one of these is a hatch-year bird. They are a very protective species and will dive-bomb pedestrians who are near their nesting areas. The kite came from behind its target, a jogger, and dished out two quick thumps to the jogger’s head and neck. They circle the roost/nest no more than 300-400 meters from it. Swooping down from high above the treetops, the Mississippi kite, a hawk-like bird of prey, dive-bombed a perceived threat on the ground. 84(3):255261, 2013 DOI: 10.1111/jofo.12024 Distribution and migration of Mississippi Kites in South America Matias A. Furthermore I have not been able to see a nest. They vocalize regularly, but they are so well hidden it has been difficult for me to point a microphone at them. I have had one or more Mississippi Kites roosting or nesting in a large Loblolly Pine on my property all summer.
