Although a pair of Barn Swallows was perching near this already-built porch nest earlier this spring, the pair ceased doing so during May. On June 13, 2014 we first observed adult Cliff Swallows inside the nest, guarding and adding mud to it. In retrospect, assuming a 14-day incubation period, there must have already been at least one egg in the nest on that date because on June 30 and on subsequent days we observed a chick through the nest’s entrance hole. There may have been more chicks in the nest, but they were not visible. On July 2 I took this photo from inside my apartment through a crack in my blinds and through two layers of glass. It shows the chick inside the nest with two adults on the outside, presumably about to feed the chick. During that time period, there were often more than two adults seeking entrance to the nest, but not all of them were allowed inside because an adult inside the nest’s entrance would peck some of them away. Once an adult would gain entrance to the nest, it would often seem to be feeding the chick and adding mud to the nest at the same time. We no longer observed this chick in the nest, or any adults guarding the nest, after July 8. We therefore assume that this chick fledged on July 9.

The above is the correct URL for a detailed chronology of Cliff Swallows nesting on my porch during spring 2014.
