Sketching birds is a wonderful way to make yourself look more carefully at nature. I have completed work on a comprehensive book on drawing birds, The Laws Guide to Drawing Birds, which will be published in 2012. In the meantime, I have assembled a set or resources that I hope will help you draw birds and understand them more deeply. If you understand bird anatomy you will be better at drawing what you see. I will add more details and tips in future posts. Please leave comments and questions and I will expand these resources based on your input. I also have many blog posts on drawing birds. Be sure to check those out (click birds in the floating cloud to the right).
Start with the basic Shape
The most important part of the drawing is getting the basic shape right at the start. Instead of focusing on details at the start of a picture, make light sketch lines to capture the posture, proportions, and angles of your subject. Start your bird sketch by noting the posture of the bird or the angle at which it sits with a single line. Over this, add an oval for a body and then a circle for the head. Then stop and check your proportions. It is easy to change the size of the head early in the drawing. You will notice that I initially drew the head too large. I redrew the head circle smaller after my proportion check so that this Song Sparrow will not have a head with the proportions of a chickadee. Indicate the locations of eye-beak, tail, leading edge of wing, and legs. Carve in angles where you find them around the head and tail coverts. These angles around the head and tail help break the imprint of the two circles that you used to initially build the bird. Without this, it is easy for your drawings to resemble a snowman.Many artists speed past these important initial steps but time spent at the start will pay off in the end. One you capture the the posture, proportions and angles of the silhouette, you can add details in heavier pencil over these initial lines, finishing with color.
Downloadable PDF worksheet
Here is my step by step process to block in the shape of the bird. Steps 1 through 5 are handled as lightly as possible (either with minimal pressure with a graphite pencil or a col-erase Non-photo blue pencil (see equipment list). Click and drag the PDF below to your desktop to save and print it for future reference. Teachers may use this page to help their class learn to draw birds.
Look below the surface
Underneath the feathers, a bird looks like a plucked chicken. Note that it's knee is actually hidden up under its feathers and the joint you sometimes see below the body is actually its ankle! The wing feathers attach to the hand and forearm.
Learn to see feather groups
Studying bird anatomy will help you draw birds more accurately. Feathers grow from specific regions on the bird's body with bare skin between them. These feather groups define the shape and contours of a bird and the patterns on the feathers relate directly to the underlying feather group. This animation shifts between a drawing of a Song Sparrow,its shape without feather patterns, and a diagram emphasizing the feather groups. 
Birds are shape shifters
The feather groups are under individual muscular control and can be fluffed up or moved together. Birds fluff themselves up when they are cold and smooth their feathers when they warm up. Birds also fluff their feathers a part of displays. Watch carefully as the bird's shape changes as different feather groups are puffed out or relaxed.
Wonderful, John! I learned a bit from one of your GGAS workshops and look forward to your book.
I came across your site via the iPad Flipboard app. That is a very cool animation about How To Draw A Boid, and I appreciate the effort that went into putting it together.
Thank you Dave, I hope it is of help to you. I scanned my drawing as I drew it and pasted them together.
For a reference people can go to you tube, google images or a stock website. I always use this site for mybird photos.
Very helpful advice. Thanks so much.
Let me know if you would like any posts on specific topics and I will try to add them.
What fun! – maybe some advice on birds in flight?
Here you go! This is a great time to watch and sketch migrating hawks.
I think you will find this blog helpful. http://www.johnmuirlaws.com/art-and-drawing/how-to-draw-birds-in-flight

Your drawings are lovely, and depict the life and attitude of the bird. I also paint birds for a living for field guides. I had the privilege of visiting with Don Eckelberry, one of my favorite bird artists. He is no longer living, but it is worth looking up his work if any of your email participants want to look at some of the best bird art that was produced in the past.
Thank you for your kind words about my drawings. Eckelberry’s work is amazing. His manuscript Techniques in Bird Illustration is very helpful. Have you seen it? Please tell us about your visit with him. Where can we see some of your work?
Don Eckelberry was both gruff and kind. He did not suffer fools, but was exceedingly generous with advice and constructive criticism. I was illustrating Herb Raffaele’s Birds of the West Indies at the time (under different last name Tracy Pedersen.) Don was approachable as long as you did not have an unrealistic view of your illustrating capabilities. To those who were receptive, he had nice as well as constructive things to say. If your ego was getting in the way, he would tell you that if “all you wanted was praise, you could go home to your mother!” He sent an unsolicited letter to me, one I treasure to this day, about my illustration for the Auk (116, 2(1999) April) of a Cloud-forest Pygmy Owl and said he really liked the composition and lighting and to keep painting bird art (vs. just illustrations for plates.) It’s advice I am now following after too long of a hiatus from painting.
That is a wonderful story. May we all move forward in our art without letting our egos block us from critically analyzing our work. It is important to keep that inner critic constructive. It should support us in drawing more, each sketch or paining a lesson for the next.
Simply gorgeous work, and a truly beautiful tutorial. thank you! I hope to take a workshop from you!
