If two birds are flying around under the ceiling and you are worried they may hit the window, start by calming the room and giving them a clear way out, without chasing them. Their presence may be accidental, or it may mean they were exploring the building as a potential nesting site. The fact that there are two of them does not, on its own, reveal what they are trying to do.
Helping them leave without turning the room into a trap
- Move cats, dogs, and anyone who is likely to startle or crowd the birds.
- Switch off fans and secure heat sources or anything hazardous.
- Open one exit wide to the outdoors, provided you can do so safely.
- Close access to other rooms so the birds do not disappear deeper into the house.
- Reduce false visual routes, especially bright closed windows that can look like open space.
- Step back and give them quiet time to spot the opening.
Do not try to push them with a broom or catch them in mid-flight. Sudden movements increase the risk of collision. If the space is high up or difficult to reach, do not climb onto anything unstable; contact a wildlife protection organisation for advice instead.
Why did they come in?
An open garage door or barn entrance can attract birds that are looking for a place to inspect. Barn swallows often nest inside accessible buildings, while house martins usually build on the outside of structures. A simple navigation mistake is also possible.
After they leave, watch from a distance to see where they go. Do they keep returning to the same beam? Are they carrying mud? Is there already a nest or any young present? These clues are far more useful than symbolic interpretations. Two birds do not automatically mean a pair settling in.
Before blocking an opening, make sure no active nest depends on it
If birds are feeding chicks in a garage, sealing the entrance could stop the parents from getting back in. Do not block a used passage straight away unless you understand the situation. Contact the local LPO so a suitable coexistence plan can be arranged.
Swallows and their nests are protected in France. Do not destroy a nest or move it on your own, even if you need to clean the area or carry out work. Any intervention must be assessed with the proper organisations.
If you need to limit droppings, there are appropriate solutions, including structures installed in the correct position beneath certain nests. Placement matters: if an object is too close, it can interfere with access or make predation easier. Have the setup approved rather than improvising near the nest.
If one bird struck a window
A bird that stays on the ground, hangs a wing awkwardly, or breathes abnormally should be reported to a wildlife care centre. Becoming active again does not mean there is no internal injury. Contact a wildlife professional to find out how to keep it safe and arrange proper care.
Do not give it bread, milk, or water directly into its beak. Do not throw it into the air to test whether it can fly. If handling is necessary, follow the centre’s instructions and keep stress to a minimum, with pets kept away.
Can it be prevented from happening again?
Once you have confirmed that no occupied nest relies on the opening, adjust the house’s access points and make glass surfaces less deceptive. A single silhouette placed in one corner does not necessarily protect an entire window area; anti-collision devices need to cover the relevant section properly.
In a building where you want to welcome birds, consider creating a safe and lasting access route instead. Swallow-related arrangements should suit the species present. A generic nesting box bought without identifying the bird may never be used.
What does their visit mean?
Swallows are often linked to beliefs about luck and the return of spring. Those traditions do not explain the birds’ behaviour, and they do not predict anything about your home. You can appreciate the encounter while still meeting the practical needs of the birds: an exit, calm, and a respected nesting site.
To keep that attention on wildlife going, a guide to making a garden welcoming for squirrels follows the same principle: preserve a suitable habitat rather than trying to tame the visitors that pass through.
