The blue footed frog (Dendrobates azureus) breeds seasonally, usually during February or March when it is rainy. To find mates the males sit on a rock and produce quiet calls, which the females follow to track down the males. The females then physically fight over a male. The male takes the female to a quiet place by water, which becomes the site of the egg-laying. Fertilization occurs externally: once the eggs are laid the male will cover them in his sperm.
