Longevity information for Caiques Caiques
can be very long-lived parrots, despite their small size. My
first introduction to their longevity came in the late 1980's,
when several European breeders were discussing reproduction
in wild-caught Pionites leucogaster leucogaster and P.l. xanthomeria
that had been held in captivity for 20-30 years. Birds estimated
to be 40+ years old were observed to successfully parent-rear
their chicks, and records from two collections in England suggested
that breeding might well extend beyond age 50. Photographs
from
these collections were remarkable, as none of these older
birds appeared noticeably different in appearance from young
animals, and few age-related health problems or physical limitations
in these birds were reported.
RSCF inherited numerous P.l. xanthomeria from a collection
assembled by Dr. J. Vaughn in the late 1980's and early 1990's,
including a pair from D. Taylor in California that was imported
sometime from
the late-1960's to mid-1970's. conservatively speaking, this
pair has reproduced annually for at least 25 years, and very
likely for 30+ years. Both
birds may well be in their mid-40's,if not older, as their
age when imported is unknown. Neither has exhibited illness
during the past 12 years here, and they
are robust, healthy, noisy white-bellies that usually lay three
four-egg clutches per year.
Upon reviewing our health records for caiques, we were stuck
by the complete absence of health problems, aside from occasional
minor injury by cagemates or other accidents. Indeed, not a
single post-fledging caique has died here since I arrived in
late 1989, and every pair from that time is still reproducing,
although some have slowed considerably, and some
now lay a blend of fertile and infertile eggs. By all measures,
caiques appear to be the Eveready bunnies of the small parrot
world.
