Choosing the correct animal model is critical to successful experimentation and hypothesis testing. Birds have been used to study the effects of hormones on male reproductive behavior since Berthold's work on roosters. Describe an advantage and a disadvantage to using each of the following animal models to study male reproductive behavior.

a. White throated sparrows – these birds are seasonal breeders who show courtship behavior (singing to display territory, fighting with other males, displays to females) in the spring.

b. Ring doves

c. Tropical kingbirds – these birds are found in South America and are (for the most part) non-migratory. They respond to photoperiod like a white throated sparrow but can breed year round when resources are available.

d. Japanese quail
