Abstract: Twenty-nine wild Cape sugarbirds (Promerops cafer) died acutely after ingestion of a homemade xylitol nectar solution from a bird feeder.
On January 9, 2014, a large flock of free-flying, wild Cape sugarbirds (Promerops cafer) were exposed to a bird feeder containing a 21.
7) On opportunistic necropsy examinations conducted during field work from January 2013 to November 2014, with Cape sugarbirds in various locations throughout the Western Cape Province in South Africa, the ceca were noted as rudimentary, tiny structures.
The Cape sugarbirds in this report died acutely, and either there was no time for coagulopathy to develop or it is potentially not a feature of xylitol toxicity in Cape sugarbirds.
In these Cape sugarbirds, a diagnosis of presumptive xylitol toxicosis was made based on the history of exposure to xylitol; the typical clinical signs of acute xylitol toxicosis, such as ataxia, depression, weakness, seizures, collapse, and death (3-6); and the macroscopic and microscopic pathologic findings that did not show any other obvious cause of death.
Results of various studies have shown that xylose as a nectar sugar does not commonly form a large constituent of nectar consumed by Cape sugarbirds, although it is present in a small proportion of the Proteaceae, which form a large part of the Cape sugarbirds nectar diet.
What can nest record cards tell us about timing of nesting and nesting success of Cape sugarbirds.
