Inner Ear Anatomy of Caenagnathidae (Theropoda: Oviraptorosauria) Emphasizes Mosaic Evolution of the Avian Neurosensory System

Journal of Comparative Neurology, Volume 534, Issue 7, July 2026.
The phylogenetic position of oviraptorosaurs close to birds makes them a key group for understanding the acquisition of avian senses. Here, we describe the first inner ear endocasts for caenagnathids, a major subclade of oviraptorosaurs, which demonstrates that labyrinth morphology varied more than expected within oviraptorosaurs.

Candling Analysis of Egg Development in an Endangered Bird Species Crested Ibis (Nipponia nippon)

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Using candling images from 98 eggs, we present the first detailed description of egg and embryonic development in the endangered crested ibis. We identify diagnostic features of nonviable eggs and reveal that embryo mortality is concentrated during mid‐incubation and shortly before hatching. These findings provide a standardized reference for assessing

Incubation Temperature for Ostrich (Struthio camelus) Eggs

Poultry Science, 2004
The impact of incubation temperature on egg weight loss, embryonic mortality, incubation period, hatchability, and chick weight in 394 ostrich (Struthio camelus) eggs was studied. Eggs were obtained from 3 farms in Texas. Three incubation temperatures (36.5, 37.0, or 37.5 degrees C) with relative humidity ranging from 20 to 30% were used.
