10x42 means that the binoculars have 10x magnification (compared to the naked eye) and an objective diameter of 42mm. 10x42 are best for bird watching, hunting, concerts, sporting events etc. They have higher magnification, good light quality but are still easy to hold steady. 12x binoculars are difficult to hold steady and 10x50 binoculars allow more 8x binoculars have lower magnification, lower light and lower image quality. In our professional experience, most people prefer the 10x42.

Yes, they are great for bird watching. I have used them in the Andes in Peru, in marshes (lots of reflection), and more recently in the woods and they always deliver crisp and colorful views.
