Analogickým studiím z Tichomoří a Mexika se podařilo experimentálně prokázat, že i lesní plži čeledi Clausiliidae - Cochlodina laminata a Alinda biplicata s rozměry těla cca 20 mm mohou projít živí zažívacím traktem středně velkých ptáků. Zajímavým poznatkem je, že ačkoli přežila pouze 2 % všech plžů, tak pokud nedošlo k poškození jejich schránky, přežilo plných 62 % jedinců nalezených v trusu.

Analogously to the studies of the Pacific area and Mexico, we were able to prove experimentally that the forest snails from family Clausiliidae – Cochlodina laminata and Alinda biplicata with a body size of approximately 20 mm can pass through the digestive tract of a medium-sized bird. There is an interesting finding that although only 2% of gastropods survived at all, 62% of those with intact (undamaged) shells survived.
