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.

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 (a few hours at dawn and a few hours at dusk) – use a timer for convenience.

A smart plug allows you to activate the caller whenever you’re sat in your garden enjoying Swifts screaming past.

The pre-loaded mp3 sound file on the memory can be updated as you prefer, with different Swift calls, or loaded to attract House Martins, for example

The caller is priced at £30 postage is £5 extra

Once you have attracted Swifts, the caller can be passed to someone else
