Plain-English summary
A 5-year-old female Pekin duck was brought to the vet because she was having trouble breathing, shaking her head, and collapsed. She had experienced similar breathing issues before, but they usually went away on their own. Unfortunately, her condition was very serious, and the vet recommended euthanasia due to a poor prognosis. A postmortem exam showed that her trachea (the windpipe) had collapsed significantly, which was causing her breathing problems. This type of tracheal collapse had not been previously reported in Pekin ducks.

Abstract
A 5-year-old, 3.72-kg female Pekin duck ( Anas platyrhynchos domestica) was presented for acute respiratory distress, head shaking, and collapse. Similar spontaneously resolving episodes had previously occurred. Physical examination revealed severe inspiratory and expiratory dyspnea. Due to poor prognosis, euthanasia was elected. Postmortem examination revealed severe tracheal collapse involving the proximal trachea. The tracheal lumen was reduced in size by 75%. Histologic evaluation revealed ossification of the tracheal rings for approximately 60%-100% of their circumference. The bone trabecules presented characteristics of mature bone with a medullar cavity containing hematopoietic cells and adipocytes. There was also osseous metaplasia of the cartilage. In the lamina propria, there was lymphocytic infiltration and fibrosis, both moderate. To our knowledge, tracheal collapse has not been reported in a Pekin Duck.
