Understanding the Loss of Maternal Care in Avian Brood Parasites Using Preoptic Area Transcriptome Comparisons in Brood Parasitic and Non-parasitic Blackbirds
Parental care is critical for offspring survival in many species.However, parental behaviors have been lost in roughly 1% of avian species known as the obligate brood parasites.To shed light on molecular and neurobiological mechanisms mediating brood parasitic behavior, we compared brain gene expression patterns between two brood parasitic species
