Survivorship (the likelihood of survival from one year to the next) and breeding dispersal (movement between breeding seasons) exhibit considerable variability at both the inter- and intraspecific levels. Using eight years of data (2008-2015), from my study site in southwest Oklahoma, I characterized survivorship and breeding dispersal of the Scissor-tailed Flycatcher (Tyrannus forficatus) in a mixed-grass prairie ecoregion. My results suggest that estimated survivorship of Scissor-tailed Flycatchers is low, especially to the congeneric Eastern Kingbird (T. tyrannus), and was likely underestimated due to the tendency of Scissor-tailed Flycatchers to disperse long distances.
