Species: The Eastern Bluebird (Sialia sialia) is seen throughout eastern North America. This bluebird has an early arrival date in Canada. It usually arrives at the same time as the American Robin and the Eastern Phoebe. After a noticeable decline in their numbers, mainly because of the competition for nesting sites with Tree Swallows, House Sparrows and Starlings, these birds are now making a strong comeback. The reason for this, is because of the large number of artificial nesting boxes with entrance holes tailored to the body size of the bluebirds. This prevents larger birds accessibility. These boxes are being installed by volunteers and can be seen throughout the countryside, attached to fence posts and trees.
Distinctions: The male has a dark blue back, head and tail feathers and a rusty-coloured red throat, breast and flank, with a white belly. The female has similar colours, except with a duller tone. The juvenile has a browner body with white speckles, blue wings and tail feather.
Voice: A low warbling song, separate call notes in flight, quiet on most occasions.
Nesting: Five to six pale blue eggs, two broods per year. These birds nest in tree cavities, holes in fence posts and bird houses. They prefer sparsely treed fields, meadows and open forests. They usualy perch on the lower limbs of a tree or fence post, where it is able to pounce on unsuspecting insects or grubs on the ground.

References to Other Bird Sites:
Avibase - the world bird database This site provides the user with a complete list of bird species, broken down per country, or in the example of the US or Canada, per state and province. Here, bird species names are available in other languages, a great asset to be used as a translation of foreign bird names.
ABA - American Birding Association This site represents an organization that maintains official records of all birds species that have been proven to have been seen inside the perimeters of the North American Continent and the surrounding bodies of water. Regular revised versions are posted to keep the bird list current at all times. This is the list used by all serious birders over their lifetime. You may be aware of the movie called the "Big Year". It was with this list that all the competing birders used in an attempt to set a new record as to how many bird species that could be seen by an individual birder in one calendar year.
I hope you will take advantage of these suggested websites. I have used each of them, in one way or another, throughout the years in my quest to better identify and understand our fine feathered friends.
