Despite a significant number of studies on the reproductive characteristics of small mammals, very little of this work has been conducted on species in Egpyt. Here, the Egyptian greater gerbil ( Gerbillus pyramidum Saint‐Hilaire, 1825) and Anderson's lesser Egyptian gerbil ( Gerbillus andersoni De Winton, 1902) in northeastern Egypt were surveyed. Breeding behavior in these species was synchronized with rainfall in the winter and spring months. Surprisingly however, the removal of individual gerbils throughout the course of study resulted in an extension of reproductive activity into the dry summer and autumn months in the latter part of the sampling. These results are discussed in the context of density‐dependent reproductive behavior in small mammals.
