Bay-breasted Warbler

Species: The Bay-breasted Warbler (Dendroica castanea) is one of the more attractive birds among the warbler family. It has suffered in decreasing numbers because of spraying programs that target the spruce budworms. This is its main source of food when on its breeding territory. It prefers coniferous forests but can also be found in deciduous forests.

Distinctions: When seen in breeding plumage, the male has a distinguished look. Chestnut-coloured crown, flanks and upper breast, black mask covering the eyes. The side of the neck, stomach and undertail show warm coloured beige tones. Brown to brownish-green back and wings. Showing two strong white wingbars. Female looks similar to male but in a much duller appearance. Both male and female transform into totally different looks when seen in non-breeding plumage. As it is similar to the Blackpoll Warbler, it can be difficult to differentiate. Both sexes are brownish-green over all and the male may have a hint of chestnut seen on its flanks

Voice: Chipping call, high pitch multiple notes, sounds like tees-teesi-teesi-teesi, continuous calling.

Nesting: Three to five off-white coloured eggs with brown or black markings. Size of the brood depends on the abundance of the spruce budworm. It nests in conifer trees, ranging in height from 10 to 20 feet from the ground, and nests are composed of fine grasses, leaves and hair.

References to Other Bird Sites:

These are links to websites pertaining to the different birding institutions, societies and organizations here in North America. Some of these same sites are a great asset to seeking out knowledge on birds in other regions of the world. Each of these links offer the user different methods to identify birds, whether it be by regions, habitat, appearance or maybe colour. Knowledge on the possibilities of where and what birds might be present are included.

Hinterland Who's Who Welcome to the Web site for Hinterland Who's Who It all started in 1963, with black-and-white vignettes about the loon, the moose, the gannet and the beaver. For more than 50 years, Hinterland Who’s Who has proudly been bringing Canada’s iconic wildlife directly into Canadians’ homes. Re-launched in 2003, the new series serves to rebuild the connection thousands of viewers made with wildlife through the original series. Welcome to our new website! Have a look around, and learn how you can help ensure that the wildlife remains part of what it means to be Canadian.

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.

The description to follow is taken from the AOS Home Page.

AOS - The American Ornitholgy Society is an international society devoted to advancing the scientific understanding of birds, enriching ornithology as a profession, and promoting a rigorous scientific basis for the conservation of birds. As one of the world's oldest and largest ornithological societies, AOS produces scientific publications of the highest quality, hosts intellectually engaging and professionally vital meetings, serves ornithologists at every career stage, pursues a global perspective, and informs public policy on all issues important to ornithology and ornithological collections. AOS is distinguished by its tremendous collective expertise, including eminent scientists, conservation practitioners, early career innovators, and students.


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.
