  • Models of parent--offspring conflict and nestling begging honesty often assume that signaling is associated with increased predation risk. However, little evidence exists that begging actually increases predation in the context in which it evolved, especially when the potentially modulating effects of parental defense are taken into account. We measured the cost of begging in cooperatively breeding bell miners (Manorina melanophrys) by baiting 168 inactive nests with a wax egg and broadcasting… CONTINUE READING
