However, since their feet are located far back on the body, loons have difficulty walking on land, though they can effectively run short distances to reach water when frightened.
Most birds, except loons and grebes, are digitigrade, not plantigrade. [2] Also, chicks in the nest can use the entire foot (toes and tarsometatarsus) with the heel on the ground. [4] Loons tend to walk this way because their legs and pelvis are highly specialized for swimming.
The span between precocial and altricial species is particularly broad in the biology of birds. Precocial birds hatch with their eyes open and are covered with downy feathers that are soon replaced by adult-type feathers. [17] Birds of this kind can also swim and run much sooner after hatching than altricial young, such as songbirds. [17]

Asked whether cat owners should buy bell collars for their pets at Christmas, he replied: "that would be good for the robins, yes".
