Webbed foot­prints

Bird Watching (UK) - - Your Birding Month -

Many wa­ter­birds have webbed feet, so nat­u­rally foot­prints show­ing web­bing are among the com­moner types of foot­print found. Of­ten these may be in mud or wet sand close to water, or even in snow as the win­ter pro­gresses. Dif­fer­ent types of swim­ming bird pro­duce dif­fer­ent types of foot­print. How­ever, note that not all swim­ming birds have webbed feet. For in­stance, grebes and Coots have lobed rather than webbed toes, and Moorhens just have long toes with­out sig­nif­i­cant lob­ing. Most wa­ter­birds with webbed feet have web­bing be­tween the front three toes. Cor­morants and Shags, though have all four toes webbed, which make very dis­tinc­tive prints. Some birds, in­clud­ing some waders, such as Avo­cet or Semi­pal­mated Sand­piper have web­bing or pal­ma­tion only cov­er­ing the basal half of the foot, with es­pe­cially the mid­dle toe hav­ing a sig­nif­i­cant un­webbed por­tion.
