A Tribute to Nick Short

It is with extreme sadness that we share the news that one of WikiVet’s founders, Nick Short, has passed away.

Nick was the driving force behind WikiVet and all that it stood for, and it is thanks to his vision, innovative approach and tireless enthusiasm and belief, that WikiVet is available as a free resource to veterinary professionals around the world today. Nick’s dedication and passion for veterinary education were truly inspirational and his very many friends, colleagues and students across the world have lost a true gem. He was an exceptional human being: gentle, good-natured, charming, generous and kind: he has left many legacies which will ensure that he will be remembered for many years.

Our thoughts are with his friends and family at this heartbreaking time. A book of remembrance has been set up for anyone that would like to leave a message of condolence for Nick and his family have asked that anyone who wishes to do so make a donation to BipolarUK, a charity that was close to Nick’s heart.

Introduction

The crop is a food storage device present in avian species. It is usually used when the muscular stomach (gizzard) is full. The crop also softens food.

It is a useful tool for avian veterinarians and owners for assessing when the bird last ate and it is especially important to ensure young chicks always have full crops. It is also a common site for impactions and surgical entry to remove foreign bodies.

Structure and Function

Crop of fowl(Copyright RVC)

The crop is a muscular chamber. It is a fusiform enlargement of the ventral wall of the oesophagus at the thoracic inlet. It bulges and lies against the breast muscles.

Innervation

The crop is innervated by the vagus nerve (CN X).

Species Differences

The crop is small in ducks and geese and is much larger and muscular in seed eating birds. Pigeons have epithelial cells in their crop sensitive to prolactin which slough when chicks (squabs) hatch, producing crop milk. Owls have no storage facility in their crops, so produce a pellet of indigestible material after every meal.
