I was trying to figure out how many Cave Swallows have been recorded in Missouri. http://www.showme-birds.com/
is not working for me, so after some quick googling I came to the Annotated Checklist of birds in Missouri, entry Cave Swallow: http://mobirds.org/Birds/SpeciesSpotlight.aspx?id=435
. I saw that it was listed here as T a, meaning 1 to 4 previous records. I don't see any previous records on eBird. So what previous records of Cave Swallow exist in Missouri?
Sangamon co IL (at present).
