“…Necropsy and histologic examination of tissues were conducted on all birds in fresh condition and cause of death and co-morbid conditions were determined by a veterinary pathologist. Identification of caseonecrotic lesions in the upper digestive tract was suggestive of trichomonosis, and wet-mount and/or immunohistochemistry (see Girard et al, 2014) confirmed the post-mortem diagnosis of trichomonosis. Lesion tissues were sampled and frozen at À80°C.…”

“…Live and recently dead birds were sampled for trichomonad infection in the oral cavity using the InPouch™ TF culture device (BioMed Diagnostics, White City, OR, USA), and positive cultures were subcultured as previously described (Gerhold et al, 2008;Girard et al, 2014). InPouch™ TF culture devices inoculated in the field were kept at 25°C during transport to the laboratory or at ambient temperature if shipped overnight.…”

“…All DNA extractions were carried out on tissues (625 mg) and trophozoite cultures using the DNeasy Blood and Tissue kit (Qiagen, USA) as previously described (Girard et al, 2014). Published primers were used to amplify the 5.8S rRNA region and flanking internal transcribed spacers (ITS1/5.8S/ITS2) and the hydrogenosomal Fe-hydrogenase region of trichomonadid protozoa (Ecco et al, 2012;Felleisen, 1997;Lawson et al, 2011a).…”

“…Risk factors under investigation include the use of artificial water and food sources, crop feeding and billing behavior, climate, bird density during congregation, bird migration, consumption of infected prey, and parasite species or genotype (Bunbury et al, 2007;Cole, 1999;Girard et al, 2014;Höfle et al, 2004;Lawson et al, 2011a,b;Robinson et al, 2010;Stabler, 1947Stabler, , 1948Stabler and Herman, 1951). The relative roles of these risk factors are expected to vary temporally, spatially, and between host species.…”

“…However, a rigorous analysis of parasite genetic background during epidemic and non-epidemic transmission cycles in wild columbids of North America that are at risk of disease has yet to be described. Preliminary analysis of a small number of trichomonad isolates from mourning doves and band-tailed pigeons of the western U.S. indicate that outbreaks in these species may actually involve more than one genetically distinct trichomonad species (Gerhold et al, 2008;Girard et al, 2014).…”

b s t r a c tThe Pacific Coast band-tailed pigeon (Patagioenas fasciata monilis) is a migratory game bird of North America that is at risk for population decline. Epidemics of avian trichomonosis caused by upper digestive tract infection with Trichomonas spp. protozoa in these and other doves and pigeons of the United States are sporadic, but can involve tens of thousands of birds in a single event. Herein, we analyze the role of trichomonosis in band-tailed pigeon mortality and relate spatial, temporal and demographic patterns of parasite transmission to the genetic background of the infecting organism. Infections were most common in adult birds and prevalence was high in band-tailed pigeons sampled at mortality events (96%) and rehabilitation centers (36%) compared to those that were hunter-killed (11%) or live-caught (4%). During non-epidemic periods, animals were primarily infected with T. gallinae Fe-hydrogenase subtype A2, and were less often infected with either T. gallinae subtype A1 (the British finch epidemic strain), T. stableri n. sp. (a T. vaginalis-like species), or Tritrichomonas blagburni n. sp.-like organisms. Birds sampled during multiple epidemics in California were only infected with T. gallinae subtype A2 and T. stableri. The non-clonal etiology of avian trichomonosis outbreaks in band-tailed pigeons and the risk of spill-over to raptor and passerine species highlights the need for additional studies that clarify the host range and evolutionary relationships between strains of Trichomonas spp. in regions of trichomonosis endemicity.

Husbandry protocols for the Band‐tailed pigeon, Patagioenas fasciata albilinea, at the WCS, Bronx Zoo for future conservation management programs

From 2015 to 2016 we determined the husbandry protocols involved in the captive rearing of the Band-tailed Pigeon (BTPI), Patagioenas fascinate albilinea, for use as a tool in the future management of like extant and extinct avian taxa. Current and historical ex-situ conservation management of BTPIs and the closely related Passenger Pigeon, Ectopistes migratorius, is limited in scope and required further examination. Focus on the BTPI within zoos and private aviculture facilities is currently lacking. New pressures on the wild populations and future examination of the parameters involved in the possible restoration of the Passenger Pigeon may rely on a complete understanding of these conservation management techniques. Here we report on the establishment of a colony of BTPIs, at the Wildlife Conservation Society (WCS), and detail the progress attained. A confiscated group of BTPIs was presented to WCS and allowed us to set up the colony, document the husbandry involved, and monitor neonatal development and the factors that influence that development. The information has provided a better understanding of the BTPI and has implications for the future conservation management of this and like species.
