.Adding a swift caller increases the chances of attracting a swift to your new nest.
The remote speaker is fitted close to the nest and the 10m cable runs to a nearby 230V socket (through a window, eaves or wall) where it can be switched on and off at the appropriate times – use a timer for convenience.
A smart plug allows you to activate the caller while you’re sat in your garden enjoying the swifts screaming past.
The pre-loaded mp3 sound file on the memory can be updated as you prefer.
The caller is priced at £30. and includes postage. Payments can be made through PayPal or bank transfer
