| 1930 | Summer | | | Though colonies of the Swift are nunerous in Minneapolis, apparently the only nest seen by any of the members was one which Alden Risser investigated at St. Paul on June 24th. At this time the nest held well-developed young birds. -29-The Flicker, 1930 |
| 1931 | Summer | | | Three colonies at Shakopee, but the ne$t contents never investigated. ' ·r |

Hiernenz observed Swifts collecting twigs at st. Cloud on June.3rd and on June 14th saw an almost-coJrq.pleted nest. He states that he has "found a nest of these birds i..."l this chimney · each year beginning in 1929. The nest is always placed directly · below the nest of last year and about 6 feet below the top of the chimney." |

| 1946 | Summer | | | Gathering nesting materials, May 28 and June 28, Olmstead Co., Moore; July 17, 5 young, Janet Sanford. Few persons find evidence of swifts nesting.
