North America, with about 900 species of birds, is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be considered a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea.
North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), about 16.5% of the earth’s land area and about 4.8% of its total surface.
In 2013, its population was estimated at nearly 565 million people in 23 independent states, or about 7.5% of the world’s population, if nearby islands (most notably the Caribbean) are included.
Bird diversity varies dramatically throughout the world, with nearly 10,000 species of birds in virtually every terrestrial and aquatic habitat on earth. North America has about 900 species of birds and Mexico 1026; of course there is considerable overlap.

Very useful content on the importance of well-drafted contracts. Clear agreements help avoid disputes and legal risks. This guide on Legal Contract Drafting explains the process professionally.
This was a really insightful post about North American ornithology! It’s amazing to consider that approximately 900 bird species inhabit the continent, stretching across its vast geographical borders from the Arctic to the Pacific. The summary provides a great foundation for understanding the rich biodiversity here. Thanks for highlighting this fascinating topic!
What a fantastic one-stop resource for anyone passionate about birding across North America! The fact that Mexico alone hosts over 1,000 species really puts the incredible biodiversity of this continent into perspective. The curated collection of checklists and links for Alaska, Hawaii, Canada, and Mexico makes this page genuinely useful for planning birding trips — thank you for putting this together!

This is a solid overview of North American geography and bird diversity, but it reads more like a collection of notes than a structured article. The information is good, just a bit fragmented.
It would be clearer if the content were reorganized into sections—for example:
Geographic overview of North America
Population and land area context
Bird diversity in North America
Regional bird checklists (US, Canada, Mexico, Alaska, Hawaii)
Also, the repeated links and standalone labels like “birdsSibley-Monroe Checklist” and “eagle” interrupt readability. Cleaning those up or turning them into proper headings or hyperlinks would make the piece feel more professional and easier to follow.
Overall, strong factual base, but it needs tighter structure and formatting to read like a cohesive reference page.
amazing！
