Recently, Nicole and I have spent our lunches on the back deck listening to the birds, learning them by their calls, and watching them go to the many feeders weâve set out. Thereâs this app called âMerlinâ that you can leave recording, and itâll identify all the bird calls it hears. The other day got a great look at a âgreat crested flycatcherâ through the vortex vipers. Weâd spent the week hunting him down, hearing his call but never getting a glimpse. Finally getting that sighting was rewarding as hell.
