Pretty much every time we go outside we are interfering with nature in some way. Consider the pros and cons of your interactions and behave accordingly. A minor stress on an animal can be worth the experience of the interaction and the increased appreciation for the species or nature in general. However, it's very easy to rationalize bad behavior so it's always a good idea to talk it out with other nature loving folks so you understand just what lines you're crossing. Conversely, it's easy to condemn every nature interaction and take the moral high ground, in which case you should also live in an enclosed self contained biosphere and never go outside.
I do not outright consider calls to be some kind of evil thing. But avoid - breeding season, birds that are being called by other photographers/birders, sensitive species, and overusing calls. I have about a zillion wild turkeys in my area. Using a turkey call on private property to draw a flock closer every Sunday in March wouldn't be a major stressor. Going to a park where there's a well known nesting owl and playing calls so I and a half dozen other photographers can play paparazzi isn't very respectful of the owl.
I do call at our local frogs and toads (sometimes recordings, but it somehow feels more honest if I'm mimicing their calls myself). It can help get a chorus going. Again, I do limit my time with the frogs to a photo or two before moving to the next subject. Most species of frogs are very tolerant to people sitting closely to them and you can watch their breeding activity up close if you're patient. The benefit? My appreciation for frogs and toads has grown immensely, and I've shared my experiences and photos with hundreds and hundreds of local folk who hopefully view our amphibious friends in a better light.
