Yesterday was not a typical day in the park, that's for sure. All the action was confined to the edge of the bluffs, hence the super highway analogy, because they were moving both east and west in the tree tops and from the brink of the bluffs the treetops are often below the camera. Feels kind of weird. I returned to the brink of the bluffs early this morning in full sunlight but the super highway was closed. There was hardly any activity at all. I spotted a Blue-headed vireo near the tree-tops, actually below me, but it was too far away for a detailed photograph. Away from the bluffs there was nada. I figured that yesterday's warblers may have moved a little farther north so I head up to the Rouge, north of Sheppard, and there were a few warblers, mostly Myrtle, Palm and Parula but I was more interested in a Great crested flycatcher. Also saw FOY Red-eyed vireo, and FOY Kingbird. Spotted another E. phoebe too, after not having seen one in a couple of weeks. What a difference a day makes ... 24 little hours!
