Two bird invasions were recently filmed in homes in California. These very impressive events are still usual. The specimens concerned, chimney swifts, often lodge in chimneys on their migratory path.
An impressive invasion of birds
The residents of a house in Torrance, Southern California, were recently the victims of a particularly impressive event: the arrival in their homes, by the chimney, of hundreds of birds. “On a stopped counting after 800“, Confided the owners at the microphone of the local radio KTLA.
The birds, chimney swifts, entered when the occupants were absent. A neighbor, outside at the time of the scene, still managed to film the event. Surveillance cameras then recorded the arrival of the birds inside the home.
Upon their return, the owners immediately notified the California Animal Protection Service who advised them to open all windows in the dwelling. In time, they argued, the birds will eventually go away. Obviously, they were not of the same opinion.
As a result, the owners had no choice but to evacuate them one by one. It took three days to expel them all and clean up the droppings.
A similar scene 150 km away
These people of Torrance have not been the only ones to live the experience. 150 km away, in the town of Montecito, another family suffered the same event.
Luckily, this time their chimney flue was equipped with a grid having prevented birds from entering their living room. The firefighters then intervened to evacuate the birds, filming this equally impressive scene in passing:
Ducts to rest
This type of event is not surprising. The Chimney Swift is a bird that leans almost exclusively on masonry chimneys to rest between two insect hunts and to build a nest. Their presence in a chimney does not normally represent any risk of damage. Note that before humans arrived, these birds used the central cavity of large dead or dying trees as nesting and roosting sites.
When it comes to nesting, a pair usually uses a separate chimney. And usually, this monogamous pair returns to build their nest in the same chimney year after year. As for the dormitory chimneys, they are occupied during migrations, as is the case here, allowing hundreds of individuals to gather there to spend the night or to protect themselves from the elements. In the region, the species is currently traversing southern California to the north.
