A request for list members familiar with small tern eggs damaged and/or
eaten by predators.
I have photos of Fairy Tern egg shells taken at an apparently recently
failed breeding colony off French Island Victoria.
As a member of the Friends of French Island National Park we monitor this
threatened species breeding in Western Port. The egg shell remnants
appear to have been pierced by a beak (?) of a predator of some sort. We
are aware that Barn Owls and possibly feral cats visit the breeding area
at times but are unsure of whether ravens may also be a problem. Silver
Gulls also visit the area occasionally. Some of the holes in the egg
shell remnants are too small to be either gull or raven ..
Would those people familiar with egg damage contact me directly so I can
pass on the images for their thoughts?
cheers, Martin
