One of the things I love about where we live, is occasionaly waking up to the sound of one of the resident grey shrike-thrushes, we have approx. 3 in the area (I only know that because one found a grub in our broccoli one day and the next moment the other two swooped down to try and steal it, haha) and every now and then they stop by our backyard, calling and foraging. And they have such a beautiful call. I tried to record the one this morning, but when I got back with the camera and hit record, it had moved further down the street
Here's a recording of some of their calls anyway
The one around here has a slightly different sound and there's a few more variations, but you get the idea
