These shots were taken last year with a lower mpix camera
 
Hi Henk, very nice. Is there a "sequence of events" here? Are these females (?) preparing to lay the egg sacs in the first picture?
 
No the animals in the 2nd shot are only males posting to the twigs, waiting for a female... I'll keep the sequence shots for the dunni article in the caudata.org ... :))
 
neat henk-will the males leave the egg sacs alone or will they eat them??? are the thick twigs a key to egg laying? i have some stems of plants that dip into the water that i thought might appease mine-but of the photos of yours and what ive seen in the wild -it appears that they prefer thicker ones...is this the way it is or will they lay on any 'twig'?
 
Well I prefer the thicker twigs since it must be able to carry the weight of multiple animals (males). They will normally now eat the eggs (never seen this) and you will see they prefer the twigs which go slow up and will mostly position the eggs just under the waterline. THe reason why is written in my H. dunni article which we are comiling for the caudata.org pages now (Still need to sort out some questions).
