Right near the beginning of our walk Ollie heard a Tropical Gnatcatcher and finally found it about 20 feet up in a tree. It was difficult to see in the branches, so I asked if pishing would bring it in. Ollie said that they were more responsive to the call of the Ferruginous Pygmy Owl – which sounds exactly like our Northern Saw-whet Owl. Ollie started whistling the owl’s call, but the gnatcatcher stayed up in the canopy. It appeared to be a cute little bird, just like the Blue-Gray Gnatcatchers of southern Ontario with a black cap, and just as active.
