As with ''C. annulata'' this species is found in the oesophagus and crop of domestic poultry and many wild birds. Both the adults and the eggs of this species are smaller in size but the general morphology remains the same. The earthworm is normally the intermediate host but it is possible for this species to have a direct life cycle with the L1 embryonated egg as the infective stage. Clinical signs are rare with low levels of infection though they can be associated with a loss in productivity, high parasite burdens will result in emaciation and anaemia and can be fatal. The primary epidemiological concern with this parasite is its ability to have a direct life cycle and so birds kept indoors and away from the intermediate host may still become infected.

''Capillaria aerophila'' is associated with [[Respiratory Parasitic Infections - Pathology#Capillaria aerophila|respiratory disease]] of cats and dogs. The worm can be found in the [[Nasal Cavity Inflammatory - Pathology#Infectious causes of rhinitis|nasal passages]], [[Paranasal Sinuses Inflammatory - Pathology#Infectious causes of sinusitis|sinuses]], [[Trachea Inflammatory - Pathology#Infectious causes of traacheitis|trachea]] and [[Bronchi and Bronchioles Inflammatory - Pathology#Infectious causes of bronchitis or bronchiolitis|bronchi]]. The presence of the worms causes a mild catharral inflammation and can cause coughing in dogs but not in all cases.In heavy infestation may cause obstruction of the lumen of airways and may develop into secondary [[Lungs Inflammatory - Pathology#Bronchopneumonia|bronchopneumonia]]

**Some dogs cough but often no symptoms
