Iris coloration and a case of temporary heterochromia in the Red-bellied Grackle (Hypopyrrhus pyrohypogaster)

ABSTRACT: We describe overlooked patterns and age-related variation in the iris coloration of the Red-bellied Grackle (Hypopyrrhus pyrohypogaster), a range-restricted threatened species of the Colombian Andes. Whereas adults exhibit a bicolored pale yellow/scarlet red iris, juveniles show a dark iri...

description ABSTRACT: We describe overlooked patterns and age-related variation in the iris coloration of the Red-bellied Grackle (Hypopyrrhus pyrohypogaster), a range-restricted threatened species of the Colombian Andes. Whereas adults exhibit a bicolored pale yellow/scarlet red iris, juveniles show a dark iris, ranging from dark brown to grayish brown. In addition, we report the first case for a Neotropical species of temporary heterochromia iridis, an uncommon phenomenon in birds, from recaptures of a female Red-bellied Grackle in 2010. Our observations suggest that this case of heterochromia may be related to stress and changes in blood flow to the eye.

Mientras los adultos presentan un iris bicolor con amarillo pálido y rojo escarlata, los juveniles muestran un iris oscuro que va desde café oscuro a café grisáceo. Adicionalmente, reportamos el primer caso para una especie Neotropical de heterocromía temporal en la coloración del iris, un fenómeno poco común en aves, a partir de una hembra de Cacique Candela recapturada en 2010. Sugerimos que este caso de heterocromía pudo estar relacionado con el estrés y cambios de flujo sanguíneo al ojo.COL01472676application/pdfengAsociación Colombiana de OrnitologíaBogotá, Colombiahttp://creativecommons.org/licenses/by-nc/2.5/co/https://creativecommons.org/licenses/by-nc/4.0/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Iris coloration and a case of temporary heterochromia in the Red-bellied Grackle (Hypopyrrhus pyrohypogaster)Coloración del iris y un caso de heterocromía temporal en el Cacique Candela (Hypopyrrhus pyrohypogaster)Artículo de investigaciónhttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAntioquia (Colombia)Iris (ojo)Iris (Eye)Heterochromia iridisHypopyrrhus pyrohypogasterColoración del irisOrnitol.
