Notes:
.
I saw Bob Shrike today (Wednesday, 22 June 2011) at 10:45 a.m. perched on a twig of a tree. He looked like he was drenched from the rain and was "cleaning" himself. At some point in time he suddenly flew away when he heard the sound of a "baby" bird, presumably his fledgling (inakay). I followed him but I was not able to see the "baby" bird; I only heard its cry...
