Abstract

Egg type is one factor that is likely to influence the results from artificial nest experiments. Here I document predation rates on Japanese Quail (Coturnix japonica) and the much smaller Zebra Finch (Taeniopygia guttata) eggs on the edge and interior of a tropical forest in Costa Rica. Predation rates on finch eggs were the same on the edge and in the interior of the forest (60.9 and 60.0%, respectively), while predation rates on quail eggs were significantly different on the edge and in the interior (76.5 and 35.0%, respectively). Hence, results from artificial nest experiments may be highly dependent on the type of egg used and caution is advised in their interpretation.
