Blue Petrels Y-Maze is a plastic Y-maze made from standard PVC wire. It was used by Sarah Leclaire et al. (2017), to show that blue petrels recognize the odor of their eggs

The maze had three symmetrical arms. One arm was used as starting point and was fitted with two trap doors to provide a temporary holding compartment for the test bird. The end of each choice arm was equipped with a separate compartment for the odor source, also accessible via a trap door to the outside

Eggs were placed onto a small cup made of aluminium foil. A second partition was positioned 20 cm from each end and equipped with a central processing unit cooling fan. Petrels were presented with a binary choice
