Reproductive Success in House Sparrows: A Captive Breeding Study Rachel Bernard Advisors: Dr. Jonathan Prather and Dr. Alexandra Rose

Reproductive Success Fitness is determined by an organism’s ability to reproduce successfully. Animals generally breed so that young are born when resources are most abundant. Garden-birds-need-a-helping-hand.html

Reproductive Timing Animals use many different cues to determine the beginning and end of the breeding season. It is a mystery as to which factor is most important, but photoperiod is likely to play a key role.

The Influence of Photoperiod on Reproduction Allows for a cue that is reliable. Photoperiod elicits an increase in the release of sex hormones in birds. (MacDougall-Shackleton, 2009) Photoperiod could also be a factor in reproductive success.

Purpose of the Experiment The goal of this experiment is to successfully breed house sparrows indoors, which hasn’t been done before. Importance of photoperiod in reproductive success has not been tested. To test photoperiod as an independent factor, birds must be bred entirely indoors.

House Sparrows Birds are ideal subjects because they are seasonal breeders. House sparrows were chosen because they produce a large clutch size. House sparrows fare well in captivity.

Methods 40 house sparrows (20 male, 20 female) caught from the wild 5 male-female pairs placed in each of 4 indoor aviaries. Photoperiod lengthened to send the birds into a reproductive period (winter  summer). Nests were monitored every other day until the first egg appeared, then checked every day.

Methods

Results

15 of the 21 nest boxes had nesting material in them. There was a total of 27 nests. A total of 41 eggs were laid. The maximum clutch was 4 and the minimum was 1.

Discussion We have developed methods to breed house sparrows entirely indoors under controlled photoperiod conditions. Results provide tools to investigate the importance of photoperiod in shaping reproductive success.

Further Investigation It is known that reproductive success varies in accordance with latitude (Biancucci, 2010) Many factors covary with latitude, such as temperature and photoperiod. Can isolate individual factors to test relative importance in affecting reproductive success.
