Swallows.
They wait for the birds to return.
It is not only birds that fly. Bats fly and they are not birds.
In spring, many bird species fly north as they return to their breeding grounds. This migration is driven by the availability of food and suitable nesting habitats that emerge as temperatures warm. Conversely, in the fall, these same birds typically migrate south to escape colder weather.
Migratory birds fly south during autumn and return north in spring.
The Swallows of Capistrano refer to the annual migration of cliff swallows to San Juan Capistrano, California, where they return each March. This phenomenon is celebrated on March 19th, St. Joseph's Day, marking the birds' arrival and the beginning of spring. The swallows are known for nesting under the eaves of the historic Mission San Juan Capistrano. Their migration is a significant cultural event, attracting tourists and inspiring local traditions, including festivals and community celebrations.
Swallows fly to Capistrano between March and October during their annual migration. They usually arrive in late March and depart by early October.
