No nest of the Cape Pygmy-Owl (Glaucidium gnoma hoskinsii) has been reported previously. Therefore, it is of value to put on record the observation of a nest in a cavity in a Mexican fan palm (Washingtonia robusta) at an elevation of 360 m near the east base of the Sierra de la Laguna in the cape region of Baja California Sur, Mexico. The nest had at least one young near fledging on 28 May 2023. Prey carried to the nestlings included small lizards.
