Juvenile birds apparently need dense vegetation to hide in during fledging; the uncommon native sacaton grass Sporobolus wrightii is preferred, but stands of introduced non-native Lehmann lovegrass (Eragrostis lehmanniana) and Boer lovegrass (E. curvula var. conferta) are also successfully utilized, though at lower population density.<br /></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7053593248709334689-5454645814800438194?l=jmboling.blogspot.com' alt='' /></div>Leslie Johnnyhttp://www.blogger.com/profile/17644613898944360884noreply@blogger.com0
