Abstract The Diederik cuckoo, Chrysococcyx caprius , is a small Afrotropical bird in the family Cuculidae. It taxonomically related to 13 other species within genus and migratory sub‐Saharan Africa. has unique breeding behaviour of being brood parasite: Breeding pairs lay their eggs nests host hatchlings expel species. aim present study was investigate diversity two circadian clock genes, Clock Adcyap1 probe for relationship between genetic polymorphisms role circannual timing habitat selection (phenology) intra‐African migrants. DNA extracted from blood used PCR amplification sequencing genes 30 cuckoos. Three alleles were detected with similar genotypes individuals Northern Southern ranges while 10 having shorter North longer South. Population analyses, including allele frequency zygosity analysis, showed distinctly higher frequencies most abundant allele, containing polyglutamine repeats, as well high degree homozygosity.
