Cliff Swallow

Swallows Story
The miracle of the “Swallows” of Capistrano takes place each year at Mission San Juan Capistrano, on March 19th, St. Joseph’s Day.

As the faithful little birds wing their way back to the most famous mission in California, the village of San Juan Capistrano takes on a fiesta air and the visitors from all parts of the world, and all walks of life, gather in great numbers to witness the “miracle” of the return of the swallows.

At dawn on St. Joseph’s Day, the little birds arrive and begin rebuilding their mud nests, which are clinging to the ruins of the Great Stone Church of San Juan Capistrano. The arches of the two story, vaulted Great Stone Church were left bare and exposed, as the roof collapsed during the earthquake of 1812.

Cliff Swallow

The Great Stone Church, said to be the largest and most ornate in any of the missions, now has a more humble destiny -- that of housing the birds that St. Francis loved so well.

After the summer spent within the sheltered walls of the Old Mission in San Juan Capistrano, the swallows take flight again, and on the Day of San Juan, October 23rd, they leave after circling the Mission bidding farewell to the “Jewel of the Missions.”


Frequently Asked Questions About the Swallows

1. Where are the swallows?
The Cliff Swallows begin to arrive in March from their winter home in Argentina . Between March and October they can be seen building nests in the eaves. Due to urbanization, they seek out areas near water and food sources such as a concrete under pass or bridge near creeks. They start their migration back to Argentina in October.

2. Do the swallows still come back?
The Swallows come back every March.  When the Great Stone Church was stabilized, the preservationists removed the nests that had been constructed over a very long period.  When the nests were removed, the swallows diverted to other portions of San Juan Capistrano.  Also, the swallows came back to the Mission because it was the main and biggest building. With the development of the community, there became alternative locations for them to build their nests.


Swallows Vocalization Experiment

Swallows Vocalization Experiment
Urbanization has resulted in fewer sightings of the birds during their annual migration from Argentina each spring in recent years. But cliff swallows expert Dr. Charles Brown came up with an idea that is making a difference.

Under Brown's direction, the Mission established a vocalization project that lures the swallows back to the Mission. The project involves speakers playing cliff swallow courtship calls that are placed behind the statue of Father Junipero Serra on the Mission grounds.

Mission San Juan Capistrano's enterprising Swallows Vocalization Project is now underway for the fourth and final season, an effort to lure the popular birds onto the mission grounds.

"The recording is of courtship songs that males use to attract females. And males would be attracted too because they are very social birds," Dr. Brown said. "It's a matter of attracting them in; we know they are overhead and in the area.”

The project involves a systematic program of playing the courtship calls and songs a few times a day, when the weather is good and during the times the swallows would be foraging.

Dr. Brown has suggested that this be the final year of the Swallows Vocalization Project so that he can incorporate a new phase in attracting the bird. Stayed tuned for Dr. Brown's next idea.

The project this year began on February 1. They built it, now come watch the swallows return to Capistrano.

Mission Swallow Policy Statement:
Our signature swallow consists of an illustrative fork tail swallow, in-flight. This type of swallow art is unique to the Mission San Juan Capistrano brand because of its popularity in the 1930s and usage in vintage and historic memorabilia. The American public, and even the world at large has come to associate the Mission San Juan Capistrano landmark as the home of these famed birds. When the Mission portrays the literal swallows, we use the photographic, authentic and real life image. In graphic form, we use the romantic version, fork tailed, in-flight swallow.
