I’m making these to support the boxes that I install and I have a few spare but numbers are limited so please contact me to purchase and expect to wait a week or so before postage.

Adding a swift caller increases the chances of attracting a swift to your new nest.

Play it for a few hours at dawn, a few hours at dusk and or when you see Swifts aloft!

Fix the speaker close to the nest and run the 10m cable to a nearby 230V socket (through a window, open eaves or drill a wall or window frame) 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 whenever 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.
