Description:

These data compare mean length, mean breadth, and egg color, between cuckoos and their hosts.

Variables:

A data frame with 6 observations on the following 13 variables.

clength

mean length of cuckoo eggs in given host's nest

cl.sd

standard deviation of cuckoo egg lengths

cbreadth

mean breadth of cuckoo eggs in given host's nest

cb.sd

standard deviation of cuckoo egg breadths

cnum

number of cuckoo eggs

hlength

length of host eggs

hl.sd

standard deviation of host egg lengths

hbreadth

breadth of host eggs

hb.sd

standard deviation of host egg breadths

hnum

number of host eggs

match

number of eggs where color matched

nomatch

number where color did not match

Details

Although from the same study that generated data in the data frame cuckoos, the data do not match precisely. The cuckoo egg lengths and breadths are from the tables on page 168, the host egg lengths and breadths from Appendix IV on page 176, and the color match counts from the table on page 171.
