Lesser Prairie-Chicken (Tympanuchus pallidicinctus) is a medium-sized (38-41 cm), grouse-like gamebird that is distributed discontinuously through the southwestern Great Plains area. They live in grasslands with shinnery oak and/or sand sagebrush. In spring, males gather together at leks or booming grounds where they display for mates. Threats facing the species include: conversion or degradation of native grasslands, shrub encroachment, and development within lesser prairie-chicken habitats. They may avoid vertical structures (including turbine towers and transmission lines) that create disturbance or serve as perches for predatory raptors.
