Article Abstract
Forty-eight scaled quail (Callipepla squamata) were collected during August 2002 at Elephant Mountain Wildlife Management Area in Brewster County, Texas, and examined for helminths. Eight species of helminths were found (5 nematodes and 3 cestodes), representing 2,811 individuals. Of these species, Gongylonema sp., Procyrnea pileata, and Choanotaenia infundibulum are reported from scaled quail for the first time. Prevalence of Aulonocephalus pennula, Gongylonema sp., Oxyspirura petrowi, Physaloptera sp., P. pileata, C. infundibulum, Fuhrmannetta sp., and Rhabdometra odiosa was 98, 2, 56, 4, 60, 2, 25, and 35%, respectively. Aulonocephalus pennula numerically dominated, accounting for 88% of total worms. Statistical analyses were performed on the 5 species with > or = 25% prevalence using the after-hatch-year host sample (n = 38). Prevalence of P. pileata was higher (P = 0.049) in females than in males and higher (P = 0.037) in the sample collected from the site that had spreader dams (berms 1-2 m high and 4-55 m long constructed in varying sizes to catch and retain rainfall) than the control site (no spreader dams). Higher rank mean abundance of A. pennula and O. petrowi (P = 0.0001 and P = 0.0052, respectively) was found in the host sample collected from the site that had spreader dams than the control site. A host gender-by-collection site interaction (P = 0.0215) was observed for P. pileata. Findings indicate that scaled quail are acquiring indirect life cycle helminths in arid western Texas habitats.

Birds are one of the most diverse groups among terrestrial vertebrates. They evolved from theropod dinosaurs, are closely related to the sauropsid group and separated from crocodiles about 240 million years ago. According to the IUCN, 12% of bird populations are threatened with potential extinction.

In this publication various serum biochemistry and haematology parameters were determined from blood samples obtained from captive adult individuals of an exotic quail species, the mountain quail (Oreortyx pictus, Douglas, 1829). Venipuncture was performed in the second half of the breeding season from six roosters (males) and seven hens (females). During the examination, in addition to the haematological elements, basic parameters of serum enzyme levels, the products of protein metabolism, uric acid and the most important ions were monitored.

It has been demonstrated that helminths are capable of critically impacting the fitness of their hosts. This has typically been shown experimentally through the administration of anthelmintic drugs but are rarely performed on a landscape or host population scale. Here, the anthelmintic fenbendazole (FBZ) was mixed in a supplemental feed and provided to a free-ranging population of Northern bobwhite quail ().

T-2 toxin is a member of class A aspergilloides toxins, one of the most prevalent mycotoxins that contaminate feed and food. Direct ingestion of animals or feed contaminated by T-2 toxin can cause various animal diseases. Butyrate is an organic fatty acid featuring a four-carbon chain, which is commonly found in the form of sodium butyrate (NaB).

Ecological risk assessments of agrochemicals have traditionally depended on in vivo guideline tests using northern bobwhite and mallard to provide relevant endpoints for avian species. However, these studies have limitations, including animal welfare concerns, the time and cost involved, limited potential for extrapolation to more realistic exposure conditions, and the lack of mechanistic understanding. The proof-of-concept work presented a case study for thiamethoxam in three avian species, demonstrating the potential of physiologically based kinetic (PBK) modeling to enable dosimetry extrapolations that inform hazard characterization in risk assessment, and reduce the use of avian testing.
