Distribution of four annual measurements with respect to annual mating success (i.e., number of mates with which an individual produced offspring over the course of a calendar year) for male Brown Treesnakes (Boiga irregularis) collected over a 14‐year period from a geographically closed 5‐hectare population on Guam. Annual measurements include standardized average snout–vent length (“Standardized SVL”), number of times the individual was captured in a baited trap (“Trappability”), average body condition index (=BCI), and degree of genome‐wide inbreeding (“Inbreeding”). There were a total of 661 annual observations of 207 males
