House finches are desert birds native to Mexico and the southwestern United States of America. They are relatively well studied in terms of their diet, breeding, and migration patterns, but knowledge regarding viruses associated with these birds is limited. DNA viruses in fecal and nest samples of finches sampled in Phoenix (Arizona, USA) were identified using high-throughput sequencing. Seventy-three genomoviruses were identified, belonging to four genera: Gemycircularvirus (n = 27), Gemykibivirus (n = 41), Gemykroznavirus (n = 3) and Gemykrogvirus (n = 2). These 73 finch genomoviruses represent nine species, eight of which are novel. This study reiterates that these genomoviruses are ubiquitous in ecosystems.
