The swift is on the amber list of birds of conservation concern in Ireland because its population has declined by over 40% in the last 15 years.
They come to our towns every year for just four months, arriving in late April and leaving in late August.
These are four important months because they are coming here to breed.
Swifts are faithful to their nest sites. Once they have found a place to nest, they will return to there every year for the rest of their lives.
Work is being undertaken to help save the swift in Ireland by erecting nest boxes, surveying for traditional sites and rescuing injured birds.
