Lovely walk at Sharon Woods

Saturday 20 May
There was plenty to see on our afternoon walk at Sharon Woods, Great blue heron, several Canada geese families and flowers and blooms of various kinds, yellow iris, the lovely blossom of the tulip tree, centre right, Southern Arrowwood, so my nature app. tells me - a member of the viburnum family, and an unknown tree top left. My app couldn’t help me. Can any of my American readers help me out? Neither of us were feeling very energetic today, so we just did the loop around the lake, without the extra spur through the gorge and back.
