Does brood reduction provide nestling survivors with a food bonus?
Article Abstract:
Research undertaken with brown pelicans, Pelecanus occidentalis, indicates that parents bring less food when their brood is reduced through siblicide. This goes against the previous assumption that seniors receive unchanged food supplies or a rise in food supplies after the death of a junior. It is presumed that parents increase their ability to invest in future broods by reducing food supplies following brood reduction. This in turn benefits seniors, as they will gain more future siblings.

Sex-dependent risk taking in the collared flycatcher, Ficedula albicollis, when exposed to a predator at the nestling stage
Article Abstract:
Parents seeing a predator may stop feeding nestlings temporarily, reducing their own predation risk, but also reducing the offspring's changes of survival. In a study, parent flycatchers observing a stuffed sparrowhawk, were assessed for return time. Males took more risk for older and better quality nestlings, while females took significantly less risk.
