The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Cuckoo adaptations: trickery and tuning (2011, background): “For example, within their own broods, the most intensive begging is likely to come from their most needy chicks and their larger, fast-growing young are the ones most likely to survive (Wright & Leonard, 2002).”
Sibling competition and cooperation in mammals: challenges, developments and prospects (2007, background): “…competition models, which for reasons of space we can only point to here (Macnair and Parker 1979; Parker and Macnair 1979; Mock and Parker 1997; Wright and Leonard 2002) mostly tailored with birds in mind (for contest competition, see Drummond 2006; scramble competition, Harper 1986; supply…”
The evolution of nestling discrimination by hosts of parasitic birds: why is rejection so rare? (2006, unknown): “Parents’ cognitive ability to respond to minor differences in continually changing nestling morphology and vocalizations when allocating food within a brood (Wright and Leonard, 2002) also casts doubt on the ‘changing chick appearance’ argument.”
Variation in Individual Investment Strategies among Social Animals (2006, background): “…competition (e.g. whether offspring can manipulate their parents to feed them more, Clutton-Brock 1991; Kilner & Johnstone 1997; Mock & Parker 1997; Wright & Leonard 2002), and within-group conflict (e.g. whether dominant breeders can make subordinates to ‘pay-to-stay’ for continued group…”
