Every year, multiple pairs of Violet-green Swallows nest in buildings on the CU Boulder campus, usually in the space between the red tile roof and the gutter, as far as I've been able to ascertain.
The species also nested in cavities under the eaves of the log cabins of the summer camp where I used to work near Estes Park.
