HENSLOW'S SPARROW HABITAT ASSOCIATIONS ON KANSAS TALLGRASS PRAIRIE

摘要: We examined macro- and microhabitat characteristics of breeding Henslow's Sparrows (Ammodramus henslowii) on Fort Riley Military Reservation, Kansas during 1995 1996. Survey points were identified at the macrohabitat scale as either grassland, savanna, or woodland edge. A military disturbance index was used to quantify severity training vegetation survey bird use sites. At large scale, associated with grassland habitat last burned in 1993, two three years previously. Microhabitat Sparrow sites had lower tree density than random points, but neither shrub nor differed between spring. In summer, track higher Sparrow's Habitat by consistently tall dense high litter cover early spring, late summer whereas changed response growth. Characteristics included dense, structurally homogeneous vegetation, depth standing dead physiognomic diversity, did not differ from points.
