Trichodinid ciliophorans are opportunistic parasites of many species of fish, amphibians, and molluscs, but yet never reported in association with lesions in birds. This study investigated the regulations of photostimulation and photorefractoriness that govern the onset and cessation of the breeding period. Geese are the economically most important species of poultry around the world. The bird will usually keep visiting the nest box without being able to lay the egg and will keep straining. "There are two components of her reproductive system that need to recover — the brain (hypothalamus) and the uterus. These components are regulated by environmental, genetic, physiologic, hormonal, behavioral, and psychosocial factors. The ovary contains thousands of ova (see the diagram below) which can develop into the yolk and eventually an egg. Birds have very efficient cardiovascular systems that permit them to meet the metabolic demands of flight (and running, swimming, or diving). At full length, the duck's penis can reach 20 cm .
