Additionally, the serosa covering the deferent duct was easier to tear with biopsy forceps, which allowed a more precise grip of the duct compared with the use of grasping forceps.
Therefore, we assume that the relevant females must have either copulated with a foreign fertile male from outside the pigeon houses or that the relevant males remained fertile for a certain period after vasectomy due to retaining spermatozoa within the caudal deferent duct, which was also described in zebra finches (Taeniopygia guttata) (22) and red-winged blackbirds.
