From the Wiki:
The Cliff Swallow (Petrochelidon pyrrhonota) is a migratory bird that spends its winters in Goya, Argentina but makes the 6,000-mile (10,000 km) trek north to the warmer climes of the American Southwest in springtime. According to legend the birds, who have visited the San Juan Capistrano area every Summer for centuries, first took refuge at the Mission when an irate innkeeper began destroying their mud nests (the birds also frequent the Mission San Carlos Borromeo de Carmelo). The Mission’s location near two rivers made it an ideal location for the swallows to nest, as there was a constant supply of the insects on which they feed, and the young birds are well-protected inside the ruins of the old stone church.
In addition to all that, it would have been my Mom’s 73rd birthday today. She used to tell us about the swallows returning to Mission San Juan Capistrano each year, just for her birthday. Happy Birthday, Mom!
