Variation in Brood Sex Ratios of Texas Rio Grande Wild Turkeys

The Journal of Wildlife Management, 2007
Abstract: We evaluated brood sex ratio (BSR) variation in Rio Grande wild turkeys (RGWT; Meleagris gallopavo intermedia ) in the Edwards Plateau and South Texas Plains of Texas, USA, during 2005‐2006.

Molecular Surveillance for Lymphoproliferative Disease Virus and Reticuloendotheliosis Virus in Rio Grande Wild Turkeys (Meleagris gallopavo intermedia) in Texas, USA

Journal of Wildlife Diseases, 2022
Reticuloendotheliosis virus (REV) and lymphoproliferative disease virus (LPDV) are avian retroviruses that can cause neoplastic disease and present with similar pathologies. Lymphoproliferative disease virus has been reported in the Eastern US and states bordering Texas, USA, but has not been previously detected within the state.

Abnormal Eggs of Rio Grande Wild Turkeys on the Edwards Plateau, Texas

The Wilson Journal of Ornithology, 2008
Abstract We studied the reproductive ecology of Rio Grande Wild Turkeys (Meleagris gallopavo intermedia) in the Edwards Plateau region, Texas during 2005 and 2006. Runt eggs from a single adult female were observed through three nesting events over 2 years. Mean mass and volume for the runt eggs were 44% of normal Wild Turkey eggs.

Predation of Rio Grande Wild Turkey Nests on the Edwards Plateau, Texas

The Wilson Journal of Ornithology, 2008
Abstract We followed the fate of nests of Rio Grande Wild Turkeys (Meleagris gallopavo intermedia) on the Edwards Plateau of Texas during 2006 and 2007 using motion-activated digital cameras on a subset of nests to evaluate the frequency of nest predation and to identify nest predators.

Encounter Rates From Road‐Based Surveys of Rio Grande Wild Turkeys in Texas

The Journal of Wildlife Management, 2010
ABSTRACT  Traditional index‐based techniques have indicated declines in Rio Grande wild turkey ( Meleagris gallopavo intermedia ; hereafter, wild turkey) populations across much of Texas, USA. However, population indices can be unreliable.

Nest site fidelity and dispersal of Rio Grande wild turkey hens in Texas

The Journal of Wildlife Management, 2012
AbstractRio Grande wild turkey (Meleagris gallopavo intermedia) nests suffer high predation rates exceeding 65%, which may limit recruitment. We evaluated post‐nesting movements of reproductively active female Rio Grande wild turkeys. We monitored 194 nesting attempts between 2005 and 2010 and documented 17% and 32% overall apparent nest success for ...

Poult Adoption and Nest Abandonment by a Female Rio Grande Wild Turkey in Texas

The Wilson Journal of Ornithology, 2006
Abstract While evaluating reproductive parameters in Rio Grande Wild Turkeys (Meleagris gallopavo intermedia) in the Edwards Plateau region of Texas, we observed a case of poult adoption and abandonment of an active nest. In wild turkeys, adoption of poults has been described previously, but during our observation the hen also abandoned her nest at a ...

Dilated Cardiomyopathy in a Rio Grande Wild Turkey (Meleagris gallopavo intermedia) in Southern Utah, USA, 2013

Journal of Wildlife Diseases, 2015
Abstract A male Rio Grande Wild Turkey (Meleagris gallopavo intermedia) living in semidomestication was submitted for necropsy. Emaciation, a greatly enlarged heart, and chronic passive congestion of the liver were present. Dilated cardiomyopathy occurs in domestic turkey flocks but has not been reported in Wild Turkeys.

Comparison of Microhabitat Conditions at Nest Sites Between Eastern (Meleagris gallopavo silvestris) and Rio Grande Wild Turkeys (M. g. intermedia) in Northeastern South Dakota

The American Midland Naturalist, 2003
Rio Grande wild turkeys (Meleagris gallopavo intermedia) were trapped in Oklahoma and released in northeastern South Dakota during the early 1970s. Based on wintering counts, this population peaked at over 1000 birds in the mid 1980s, but steadily declined to
