how can i add... lets say an animated model of a crow as decoration?

i've been trying to get this to work all day and no luck thus far.
i've seen it done so i know its possible.

this isn't an official tutorial or anything so if it doesn't work or its hard to understand, please don't yell at me! lol..

I'm sure you already know, but it will only work in single player.

put in your model... (npc_crow) and then goto its properties. (alt - enter)

Change the keyvalue 'target path corner' to any name you choose.. (example. 'targetpath1'). Also edit the 'Sleep State' and 'Wake Radius' to whatever you wish. I suggest playing around with those keyvalues after you got your bird to do what you want.

Ok, now put in a new entity 'path_corner' and goto its properties. Name the entity 'targetpath1' (or whatever name you chose earlier.)
This is where your bird will fly to when disturbed or whatever keyvalues you have set to make it do its action.

compile your map and your bird should fly to your 'path_corner' entity. Once you have done that, it would probably be a good time to play around with the other keyvalues to see if you can get different results.

======================================

I know it's a pretty crappy explaination and it's probably not what you wanted. I'm sure there are different ways of animating the crow but this is how i got it to work using the trial and error method.

so i guess my way was pretty much wrong... lol... found some other links that can be helpful to you.
