Oral lesions focused around the oral commissures were documented in several Sharp-shinned Hawks (Accipiter striatus) 2016–18 spring migration season at a banding station located on southern shore of Lake Ontario, New York, US. Samples inflamed and caseous repeatedly tested negative for Trichomonas gallinae poxvirus; however, large numbers capillariid eggs embedded worms consistently present. Morphologically, nematodes identified as Eucoleus dispar, which was confirmed by PCR genetic sequencing. The affected hawks displayed no other clinical signs illness, good body condition, released back into their pathway shortly after examination testing. We report unique presentation capillariosis A. striatus.
