There have been multiple recent outbreaks of porcine epidemic diarrhea virus (PEDV) in isolated, high health nurseries following the migration of red-winged blackbirds that coincided with feed deliveries . In these outbreaks it was noted that bin tops were coated in bird feces that was subsequently found to be PEDV PCR-positive. It seems, then, that birds may serve as a potential and ever-present source of feed contamination at swine farms. The objective of this survey is to characterize what role Sturnus vulgaris (the Common Starling) may serve as a potential vector for PEDV and swine deltacoronavirus (SdCV). For each virus, the investigators wish to determine:
i. Can starlings serve as a mechanical vector
ii. Can starlings pass virus in their feces
iii. Can virus replicate within the intestines of starlings
