From my experiance, its luck of the draw of what dragon spawns. Ive found that almost all fire "Dragons" spawn on dead island (carno island). This can be anything from wyverns to dragons to whelps,etc. Same thing for ice. All types of dragons only spawn in there respected place. In other words I havnt found an area thats just dedicated to Whelps only.
I hear you about the whelps. They are a neat shoulder mount, unfortanatly youll have to brave a hostal area to get on. To make matters worse, you wont always find a whelp (or other dragon) in the same area twice. Since all animal work on a weight system, it takes curtain amount of animals to be removed from the location before a new "type" of dragon (or animal) will spawn. My best advice to you is to aquire a manuverable mount and patrol a particular area your interested in.
Also, if you have alter the amouts of spawns, besure to dino wipe for the affect to take place. If not you will be waiting quite awhile for thos figures to take place. Best of luck hunting.

Does anyone know any good areas to find whelps? I've been searching forever and I have whelp weight and amount set to 6.0. I've seen more Wyverns than anything else. Carno island has 500 wyverns and there's no way I can survive there until I climb the latter of better dragons.

It would be great if people can share where they find creatures of any kind here too.

my hellkite crushes everything.... lol
