Breeding pairs should be given approximately one-year as a trial period, and if the pair has not expressed appropriate breeding behaviors a new match should be made. WebAdditionally, Naves et al. (2007) found that nest familiarity and not mate fidelity was associated with an increase in breeding success. Given the high rate of nest success in our population, it is difficult to separate nest familiarity from nest success. Therefore, it may be that pairs reunite partially due to nest success.

WebA single female produces between 5-10 litters annually. Each litter consist of 5-6 young that are able to reproduce at approximately 30 days of age. Mice produce a great number of young, but have a high mortality rate. Mice are an important source of food for wildlife such as hawks, owls, and fox which can control populations outdoors.
