Habitat Of The Long-Tailed Wood-Partridge In Central Mexico, David García-Solózano, Crisma Lopez-Sanchez, Edgardo Lopez-González, Carlos González-Rebeles Islas
Habitat Of The Long-Tailed Wood-Partridge In Central Mexico, David García-Solózano, Crisma Lopez-Sanchez, Edgardo Lopez-González, Carlos González-Rebeles Islas
National Quail Symposium Proceedings
The long-tailed wood-partridge (Dendrortyx macroura; hereafter, wood-partridge) is a forest quail endemic to the temperate forests of the Trans-Mexican Volcanic Belt of central Mexico and is considered threatened according to the Secretariat of the Environment of Mexico. We studied 34 sites within the Natural Resources Protection Area River Basins of the Valle de Bravo, Malacatepec, Tilostoc and Temascaltepec in central Mexico to evaluate wood-partridge habitat during September–December 2019. We evaluated attributes of tree, shrub, and herbaceous vegetation, canopy cover, humidity, slope, and altitude. We also identified vegetation used for nesting, food, and shelter. The scant information published for …

Nesting Of Montezuma Quail In Mexico, David García-Solózano, Carlos González-Rebeles Islas, German D. Mendoza Martínez, Ernesto Ávila González, Fidel Hernández
National Quail Symposium Proceedings
Although Mexico has the greatest diversity of quail of any New World country, basic information on the ecology and life history of Mexican quails remains unknown. Our objective was to describe nest characteristics of the Montezuma quail (Cyrtonyx montezumae montezumae) in central Mexico. We searched for Montezuma quail nests within 8 counties in the state of México, Mexico during May–September 2003. We conducted nest searches along 66 transects (3–5 km × 40 m) distributed across 17 study sites. We recorded vegetation community, elevation, and nesting substrate for each nest. We measured nest characteristics: height, depth, nest entrance diameter, …
Breeding Season Survival And Reproduction In A High-Density Bobwhite Population: A Case Study, William E. Palmer, Shane D. Wellendorf, D. Clay Sisson
Breeding Season Survival And Reproduction In A High-Density Bobwhite Population: A Case Study, William E. Palmer, Shane D. Wellendorf, D. Clay Sisson
National Quail Symposium Proceedings
The demographic behavior of northern bobwhite (Colinus virginianus; hereafter, bobwhite) populations at high densities could provide important insights into why bobwhite populations fluctuate. Therefore, we documented breeding season demographics of bobwhites to understand how prebreeding density influenced reproductive effort and postbreeding density on an intensively managed property in Leon County, Florida, USA, 2002–2006. We estimated prebreeding bobwhite density each April using multi-observer strip-transects and postbreeding densities each November using covey call grid surveys. We radio-tagged 217 bobwhites in March and located bobwhites at least 5 days/week, 15 April–30 September to determine vital rates. Prebreeding density ranged from 1.5–8.6 …
Survival And Nesting Ecology Of Scaled Quail In The Trans-Pecos, Texas, Carlos E. Gonzalez Gonzalez, Louis A. Harveson, Ryan S. Luna
Survival And Nesting Ecology Of Scaled Quail In The Trans-Pecos, Texas, Carlos E. Gonzalez Gonzalez, Louis A. Harveson, Ryan S. Luna
National Quail Symposium Proceedings
Scaled quail (Callipepla squamata) are one of the most ecologically and economically important wildlife species in the Trans-Pecos, because they are the primary upland game bird in the Chihuahuan Desert. Using radiotelemetry, we evaluated survival (Kaplan–Meier) and nesting success of quail on 3 study sites in the Trans-Pecos, Texas: one (Santiago Mountain Ranch, central Brewster Co.) was supplemented with milo (Sorghum bicolor) year-round, the second (Lado Ranch, south Culberson Co.) never used supplements, and the third (Apache Ranch, central Culberson Co.) was supplemented with quail blocks. We trapped and radiocollared 164 female quail collectively across all …
Summer Survival Of Translocated Northern Bobwhite In The New Jersey Pine Barrens: Preliminary Results, Philip M. Coppola, Kaili R. Stevens, Christopher K. Williams, Theron M. Terhune Ii, John P. Parke, John Cecil
Summer Survival Of Translocated Northern Bobwhite In The New Jersey Pine Barrens: Preliminary Results, Philip M. Coppola, Kaili R. Stevens, Christopher K. Williams, Theron M. Terhune Ii, John P. Parke, John Cecil
National Quail Symposium Proceedings
Northern bobwhite (Colinus virginianus) have declined precipitously since the 1960s, largely due to habitat deterioration and changes in land use; some of the highest declines have been observed in the Mid-Atlantic States. In other regions, attempts to augment bobwhite populations have been relatively successful using translocation. As part of a long-term restocking program, focal areas for translocation in the mid-Atlantic region were identified by biologists at a National Bobwhite Conservation Initiative (NBCI) workshop. The objective of this project is to evaluate translocation to restore bobwhite populations in the New Jersey Pine Barrens, a focal area designated with a …
