In gull species, the level of carotenoids in egg yolks is known to decrease along the egg laying sequence. However, the extent of this laying order effect is expected to vary among clutches according to laying date, due to possible differences between early-nesting and late-nesting females with regards to their ability to control the transfer of maternal resources to the eggs. A laying date effect could also result from a seasonal decline in the availability of dietary carotenoids. In this… CONTINUE READING
