Researchers in the Netherlands studied the effects of parental caregiving in European kestrels over 5 years. The researchers transferred chicks among nests to produce reduced broods (three or four chicks), normal broods (five or six),  and  enlarged  broods  (seven  or  eight).  They then measured the percentage of male and female parent birds that survived the following winter. (Both males and females provide care for chicks.) Brood Size Manipulations in the Kestrel: Effects on Offspring and Parent Survival
