Anecdotal reports of Northern bobwhite quail (Colinus virginianus) exhibiting strange behavior have raised suspicions of parasite induced host mortality (PIHM) in the Rolling Plains of West Texas. In 2017, we received 11 bobwhite carcasses associated with such reports and found parasites in all of these specimens. While further research is needed to evaluate the impact of parasites on bobwhite, these reports provide a valuable supplement to on-going investigations of PIHM in bobwhite from the…

Elevated parasite burdens as a potential mechanism affecting northern bobwhite (Colinus virginianus) population dynamics in the Rolling Plains of West Texas
TLDR
Between December 2017 and February 2018, 21 hunter-shot bobwhite from Garza and Mitchell counties in Texas were received and found peak caecal worm and eyeworm burdens averaging 599 and 44, respectively, which represent the highest average parasite loads documented in bob white from the Rolling Plains thus far.
Regional surveillance of parasitic infections in wild Northern Bobwhite Quail (Colinus virginianus) utilizing a mobile research laboratory platform
TLDR
It is proposed that the mobile laboratory would be an effective way to monitor infection levels, in addition to factors that may affect infection such as climate, diapause, and intermediate host populations.
Assessment of the helminth fauna in northern bobwhites (Colinus virginianus) occurring within South Texas
TLDR
It is indicated that the helminth community in bobwhites from South Texas can vary during long-term, highly variable precipitation conditions and these communities are more similar to those found in the Rolling Plains of Texas than those found on the eastern part of the bobwhite's geographic range in the US.
Life-cycle of Oxyspirura petrowi (Spirurida: Thelaziidae), an eyeworm of the northern bobwhite quail (Colinus virginianus)
TLDR
This study successfully replicated and monitored the complete O. petrowi life-cycle in vivo, recovering embryonated O.Petrowi eggs from the feces of bobwhite 51 days after consumption of infected crickets, and is the first to fully monitor the complete life- cycle of O. Petrowi in bobwhite.

Helminth Infection and Northern Bobwhite ( Colinus virginianus )
TLDR
Evaluated how helminths may be contributing to bobwhite population decline in the Rolling Plains of Texas shows range-wide management practices may not always be applicable.
Oxyspirura petrowi infection leads to pathological consequences in Northern bobwhite (Colinus virginianus)
EVIDENCE OF AN OXYSPIRURA PETROWI EPIZOOTIC IN NORTHERN BOBWHITES (COLINUS VIRGINIANUS), TEXAS, USA
TLDR
It is suggested that several previous studies may underreport prevalence and abundance of eyeworms because in those studies only the eye surface and nictitating membrane were examined, and not eye-associated tissue, ducts, glands, or sinuses.
Oxyspirura petrowi and Aulonocephalus pennula Infection in Wild Northern Bobwhite Quail in the Rolling Plains Ecoregion, Texas: Possible Evidence of A Die-Off
TLDR
The observed precipitous decline in quail numbers by late April 2017, and average infection had dropped to 7 ± 2 eyeworms and 252 ± 109 caecal worms, and the number of trapping sessions needed to capture one bobwhite increased from 14.26 in 2016 to 36.46 in 2017.
Infection levels of the eyeworm Oxyspirura petrowi and caecal worm Aulonocephalus pennula in the northern bobwhite and scaled quail from the Rolling Plains of Texas
TLDR
A significant difference was documented in O. petrowi infection between species but there was no significant difference in A. pennula between quail species, and nosignificant difference was detected in parasite infection between the sexes of both northern bobwhite and scaled quail.
Pathological Response of Northern Bobwhites to Oxyspirura petrowi Infections
TLDR
Histopathology showed infections of O. petrowi caused cellular damage to these tissues, scarring and interstitial keratitis of the cornea, and acinar atrophy of the Harderian gland.
The effect of a parasitic nematode on the breeding production of red grouse
TLDR
Breeding success showed a significant, negative correlation with parasite numbers in old grouse, both within and between areas, and the role of parasitic nematodes in the population cycles of red grouse is discussed in relation to current models and previous studies.
