I recently noticed honey bees on these Chuckley Pear blossoms…
…so I’m adding Chuckley Pears to my list of honey bee friendly flowers (in eastern Newfoundland, at least). As with most wild berries, it goes by several names: shadbush, serviceberry, juneberry, saskatoon berry, etc.
My 60-second Wikipedia research tells me the Chuckley Pear is called Amelanchier, though the particular species in these here parts is probably Amelanchier Canadensis.
Thanks to everyone who identified the blossoms for me.
