Birdwatching, or “birding” for short, is one of the most popular activities in the country. Over 2000 birders have joined MOS because they wanted to share the enjoyment of watching and studying these beautiful and interesting creatures with others. No matter what your skill level is, from casual backyard birders to professional ornithologist, we think you’ll find people, activities and publications that will interest you. Join one of our 15 chapters to stay informed about Maryland birds and conservation issues.
