  Male scramble competition 56
  Male territory defence 70
  Male combat in both forms 9
  Male combat in unknown form 4
Female combat 12
Combat in both sexes 9
Absence in mating combat 475
Parental care 130
  Male parental care 92
  Female parental care 48
  Parental care in both sexes 18
  Paternal care of unknown sex 8
Absence in parental care 418

The numbers may not sum up because some species may perform both male and female combat or male and female parental care.
