Designed by wildlife expert Simon King. How much should you trust his opinion? Well, this swift box comes with a whopping 30 (YES THIRTY) year guarantee... SO we'd say quite a lot. We've had multiple enquiries about Swift boxes over the years so we've brought in the very best in the business! Any of our wired cameras will also fit right in there, waiting for the Swifts arrival. Join people up and down the country in helping to protect this precious species! With a simple and robust design, this swift box can be attached on almost any building. With the entrance aperture and grip ladder crafted to meet a swift's ideal needs, it provides a great quality home for them during their nesting season. It is recommended that swift nesting sites contain a number of boxes in many different areas, as swifts tend to nest colonially and may each have slightly different preferences.
