First description of the eggs of the Sumatran Partridge Arborophila sumatrana

The breeding biology of forest partridges (genus Arborophila) is poorly understood, with nest and eggs described for just over half of all 20 recognised species. Herein we provide the first formal description of the eggs of the endemic Sumatran Partridge, based on a single preserved clutch in the Naturalis Biodiversity Centre, Leiden. Information about clutch size, egg characteristics and breeding phenology for the Sumatran Partridge is consistent with the published data available for other members of the super-species from South-East Asia

We provide a summary of published information on eggs of the endemic Sucre Antpitta Grallaricula cumanensis from Venezuela. Following the formal description of the eggs of G. c. cumanensis more than a half century ago, the natural history and breeding biology of the species still remains virtually unknown. During our investigation of inconsistencies in the linear measurements in the literature, we examined the original collection labels associated with the only three egg sets known for the Sucre Antpitta, all held at the Finnish Museum of Natural History. Herein we provide corrected linear measurements for the eggs of the Sucre Antpitta, previously unpublished information from the labels, and discuss the probable inaccuracy of the collecting locality
