The Bloedel Conservatory is home to several exotic birds such as this African Grey Parrot who whistles and calls to people passing by. Description from venturevancouver.com. I searched for this on bing.com/images
Known for its ability to mimic speech, the African grey is one of the most iconic parrots. At night they roost in large groups; it is common to see more than 100 of them perched in a single tree! Photo by Snowmanradio.
