What is the typical clutch size range observed in the nests of the Willow Flycatcher?
Answer
Three to five eggs.
The reproductive output of the Willow Flycatcher is generally modest, reflecting many small songbird species that invest heavily in the quality of their small brood. Once the female completes the construction of the carefully woven, compact cup nest, typically situated high in dense shrubbery for protection, she will lay a small number of eggs. The standard expectation for the number of eggs laid per clutch is within the range of three to five. This clutch size ensures that the parents can adequately provision the young with the high volume of aerial insects required for development until they fledge.
