摘要

Greater Rheas (Rhea Americana) lay unattended (orphan) eggs far from active nests. The objective of this study was to test the fertility of orphan eggs. Eggs were harvested and kept in storage for 1-7 d and then transported to incubation facilities. Fifteen (38/100) of 40 artificially incubated orphan eggs were fertile, ad eight of them hatched. Orphan eggs found in mid-to late spring had higher fertility than those collected in summer. These results provide the first evidence for fertility of rhea orphan eggs.
