As the most aerial of birds, swifts are difficult to observe and identify in the field. Because access to nesting sites is often difficult, large gaps exist in our knowledge about the biology of many swifts. The Black Swift (Cypseloides niger) is found locally in northwestern North America south throughout Middle America and the West Indies (AOU 1983). Some observations of its nesting biology have been published (Vrooman 1901, 1905; Michael 1927; Dixon 1935; Knorr 1950, 1961, 1962; Knorr and Knorr 1989), but the most complete works on its breeding biology emphasize only its breeding distribution (Foerster 1987, Foerster and Collins 1990), leaving many aspects unknown.
