San Diego Zoo and Safari Park (Dave Rimlinger and Athena Wilson, personal communication)
First exhibited at the San Diego Zoo in 1968
First successful breeding at the San Diego Zoo in 1992
One of the few zoos to successfully display and raise Beautiful Sunbirds, from eggs, in managed care (as of August 2016)
Chicks have been parent reared and hand reared (from day 1)
New husbandry techniques continually being developed
Still much to be learned
Social interactions observed
Interactions with other African birds species
Females appear to do most of the feeding, as do wild Beautiful Sunbirds
Have observed the male partner feeding chicks, as well
Rearing of sunbirds in managed care in the United States dates back to at least 1960 (Dellinger and Eckart 1991), perhaps earlier
Courtship and nest-building behaviors have been reported through the decades (Dellinger and Eckart 1991)
For articles on sunbird husbandry, two relevant publications include The Avicultural Magazine and The American Federation of Aviculture’s Watchbird
Husbandry
General
Sunbirds have high energy requirements (Holland 2007)
Require much time and attention, especially during acclimation (VanDegrift 1989; Holland 2007)
Diet in managed care
Adults
Artificial nectars containing carbohydrates, proteins, vitamins, and minerals (especially calcium) (Peaker 1990; Holland 2007)
Fresh fruit (VanDegrift 1989; Dellinger and Eckart 1991; Holland 2007; Athena Wilson, personal communication)
E.g., papaya and banana
Spiders, fruit flies, and other insects (VanDegrift 1989; Holland 2007)
Chicks
Spiders, crickets, meal worms, waxworms, fruit flies, and other small insects (VanDegrift 1989; Peaker 1990; Dellinger and Eckart 1991; Dave Rimlinger and Athena Wilson, personal communication)
Protein important for chick development
Chicks have a near insatiable appetite for spiders
Consumed through fledging period
Adults knock off the spiders’ legs before feeding them to chicks
Water is also important
Use frequently to bathe (VanDegrift 1989; Peaker 1990; Holland 2007)
Shelter
During breeding, require materials for nest-building (VanDegrift 1989; Holland 2007; Athena Wilson, personal communication)
