Inheritance of Egg-Colour in the Parasitic Cuckoos

Nature, 1933
THERE are many kinds of cuckoos in the Old World with so-called parasitic habits, which are more or less catholic in their choice of fosterers. One female, however, in normal circumstances places all its eggs in the care of a single species of host, and as a rule its eggs show a higher or lower degree of resemblance to those of that species.

Inheritance of Egg-Colour in the ‘Parasitic’ Cuckoos

Nature, 1934
PROF PUNNETT1 has suggested that Prof. Wynne-Edwards' ingenious hypothesis2 for explaining how the gentes of parasitic cuckoos may be kept distinct despite their promiscuous orpolyandrous matinghabits could be replaced by the assumption that it is the Y-chromosome of the mother which carries the factor assumed to determine the gens to which the ...

The evolution of brood parasitism in cuckoos

2005
Abstract Although a cuckoo nestling destroys the host eggs and nestlings, the host parents often do not dis criminate against a cuckoo egg and they incubate it with their own eggs. The hosts may lack the genetic variation that would allow evolutionary selection to favor action against cuckoos (Rothstein 1990).

Fluctuation of body temperature and cuckoo brood parasitism

Ecological Research, 1995
Abstract Body temperatures of 11 bird species, including cuckoos, were measured in an artificial meteorological room. Ratios of change in body temperature to that in air temperature were thereby obtained for each species. Cuckoos demonstrate a remarkably high value, indicating a particularly low ability to regulate body temperature ...
