Which parent primarily manages the incubation period for Yellowhammer eggs?
Answer
The female
The responsibility for incubating the clutch of typically four to five eggs falls almost entirely upon the female Yellowhammer. After the female has constructed the cup-shaped nest, usually hidden low down in dense vegetation, she undertakes the primary duty of keeping the eggs warm until hatching. This incubation period generally lasts between 12 and 14 days. While the female manages the physical task of incubation, once the nestlings hatch, the feeding duties shift to shared responsibility, with both parents relying heavily on providing insects and soft invertebrates to the young birds during their short 10 to 12 day development period before fledging.
