Chestnut-eared Bunting Egg Recognition and Cuckoo Parasitism in Southwest China

Field data from 2024 in the karst region of Liuzhi, Guizhou, southwest China, investigating cuckoo parasitism and host egg recognition. The dataset includes observations from 19 breeding nests of Chestnut-eared Buntings, with two parasitized by different cuckoo species, and egg rejection experiments in 11 nests. It was authored by Longwu Wang and last updated in April 2026.

Use Cases

• Analyze host egg rejection behavior based on the 100% rejection rate of non-mimetic model eggs.
• Study dual cuckoo parasitism patterns based on the first report of two parasitic species targeting the same host population.
• Investigate egg phenotype mismatch between host and parasite based on the described phenotypic differences.
• Model coevolutionary arms race dynamics based on the described selective pressures on egg mimicry and recognition.

Strengths

• Includes direct field observations from 19 identified breeding nests.
• Documents a 100% rejection rate of non-mimetic eggs in 11 experimental nests.
• Provides the first report of dual parasitism by Asian Emerald and Common Cuckoos on this host species.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the single study location in southwest China.
