Single-Season, multi-state occupancy with more than 2 states

[DEH]

Hi MARK experts,

I’m hoping that someone can help me out with a few questions I have about multi-state occupancy modeling with more than 2 states.

Study Design: I have several sample stations that were visited multiple times throughout the summer. Each time, observers recorded a frog call index of 0 (no frogs calling), or 1- 3 (frogs calling at varying degrees).I would like to estimate occupancy and detection for each level of the calling index (i.e., for 3 states).

Problem: Single-season multi-state occupancy models in MARK appear to allow for only 2 states.
After searching the help forum, it seems that there might be a way to use multi-season multi-state occupancy models to answer my question (as this type of model allows for more than 2 states), but it is unclear to me how this might be accomplished. My foggy notion of the concept, is that I think it involves “tricking” MARK with the use of a dummy season?

Any advice/direction to appropriate literature would be greatly appreciated!
