Sparrow Identification by Shape

As with almost any bird, shape is an important aspect of sparrow identification.  While you don't have to completely rely on it for most sparrows, it will help you become quicker with their identifications.  This graphic is a basic guideline, but in some cases, sparrows in the same genus have markedly different shapes.  I will talk about some of these differences in later posts.

Sparrow Shapes-click on the image to see it larger.
Look closely at tail and wing length, bill shape, head shape and size, and overall bulkiness.  With a little
practice these sparrows will start to look much different.
