Texas Partners In Flight Flyway NEWSLETTER Spring 2001 – Spring 2002 Volume 9 Newsletter Editor – Clifford E. Shackelford <[email protected]> Partners in Flight was formed to address the conservation needs of declining bird species. Federal and state government agencies, non-governmental conservation organizations, communities and conservation-minded corporations, landowners, and other businesses, have joined together in an international effort to address these declines. Together, we are working to understand the ecology and natural history of all birds in the Western Hemisphere, while also discovering the causes of their vulnerability. Our main goal is to implement actions needed to assure that these valuable species continue to occur in healthy and productive populations into the future. PWD BR W7000-233 (3/02) Mountain Plover: A Texas Perspective By Tim Fennell, The Science Academy of Austin at the LBJ High School <[email protected]> According to the Texas Ornithological Society’s Checklist of The Mountain Plover breeds almost exclusively in the Great the Birds of Texas, the Mountain Plover is a “rare summer Plains of North America. It’s one of a few true grassland resident in the high grasslands of the Trans-Pecos and the obligates and is strongly associated with short-grass and northwest Panhandle.” Even though there are recent mixed-grass prairies. Currently, the primary breeding range breeding records for Jeff Davis and Presidio counties, and it includes portions of Montana, Wyoming, Colorado, New occurs as a rare migrant as far east as Delta County, most Mexico, Kansas, and the Oklahoma Panhandle.

It is not that this plover is found in mountain habitats, but rather that they inhabit high elevation grass- Like the majority of grassland birds, the Mountain Plover is lands near mountains.

This plover is not what people typically Currently, the world population is estimated to be less than think of when “shorebirds” are mentioned; this one has 10,000 and, based on 30 years of Breeding Bird Survey data, been observed in water only a few times.
