An excerpt from this site:
Vancouver Island is home to only two species of Hummingbird, the Rufous and Anna’s Hummingbird. The Rufous Hummingbird is distinguished by a buffy cinnamon colouration on its body and tail. Like all hummingbirds, male Rufous have iridescent throat feathers, called a gorget. When the light catches it, the male Rufous gorget is a striking orange-red colour. Females are greener, and have spots of iridescent feathers on the throat. The Rufous is by far the most common species in our area. They arrive with the first flowers of the spring, breed here, and depart by mid summer.
The Anna’s Hummingbird is much more elusive. The Anna’s male has a fuchsia-pink gorget and a green back. Both males and females have white over the eye, and no hint of cinnamon. Anna’s have only been in BC for around 60 years. This native of California has gradually moved north, expanding its traditional range. Anna’s reached Vancouver Island in the mid 1940’s, and a breeding record was confirmed in 1958. Since then, Anna’s have been steadily increasing on Vancouver Island, especially during the past 5 years.
The reason I was interested in finding out more information about hummingbirds, is because I saw this fluffy one sitting just above the hummingbird feeder. I was surprised to see it still perched there while I went to get my camera and returned. Perhaps it's a young Rufous Hummingbird. I'll try and find out.
UPDATE: Message received re identification of hummingbird below:
The bird in your photo is a full adult male Rufous Hummingbird. Note the dark gorget (neck and head feathers) and the bright rufous-red colouring down the sides and back of the bird. Females would show a green back with some rufous-red colouring down the sides.Rufous Hummingbirds spend the summer months in the area to breed.
