Vancouver is playing host to two significant bird events this summer — the 27th International Ornithological Congress, which takes place every four years and attracts ornithologists (bird scientists) from around the world, and the inaugural Vancouver International Bird Festival.
Each week leading up to the festival and congress Aug. 19-26, we’ll highlight a different bird. British Columbia is home to 573 species of birds and many can be found in and around Vancouver.
