Viviparity is a reproductive pattern in which females retain developing eggs inside their reproductive tracts or body cavity and give birth to offspring capable of a free-living existence. Over the five conferences there was a sigmficant increase in presentations in reproductive strategies (r= 092, p= 0027), and a significant decrease in survival strategies (r=-090, p= 0040. We used seven years of data on individually marked birds to (1) determine if individuals consistently use the same migratory strategy, (2) determine if offspring have the same strategy as their parents, and (3) estimate reproductive and survival rates of the two migratory strategies.

I seek to understand the ecological and evolutionary basis of reproductive strategies and social behavior in animals, particularly reproductive parasitism, parental care and mating systems one focus is to understand patterns of cooperation and reproductive parasitism in birds and insects.
