A few methods I have personally used:

Mist nets. These are huge, thin nets that birds fly into and get tangled up it. You can either have these placed passively in bird flyways, or you can actively herd birds into them. Then you just gotta untangle them and you've got bird.

2. Nest trapping. When birds are nesting, they have a very strong drive to sit on their eggs. Depending on where they nest and their size, there are lots of different types of traps you can effectively use to capture birds on their nests. For ground nesting birds, these can be flip traps, drop traps, funnel traps, noose mats, etc. For cavity nesters, you can use trap doors or specialized nest boxes. Some birds refuse to leave their nests so much that you can use a net to catch them directly on their nest, or even just scoop em right off.

3. Molt capture. Lots of larger birds will go through a catastrophic molt, meaning that they lose a bunch of feathers all at once, which prevents them from being able to fly, and so you can effectively herd them into a corral/helgoland trap.

4. Babies! Ringers often focus on ringing baby birds because they are easy to nab.

Holy shit
