When you begin do not instantly kill all the dodos in your area because you need some easy meat and hide. What you'll want to do is start taming a bunch of them and breeding them. This results on you a) having a constant supply of eggs and b) as you breed higher level dodos you can kill off the lower level ones to get that meat and hide you need.

If you simply just don’t feel like going all the way to the south cave for your dug beetles or well any cave just use these! First get four stone battlements and make a square anywhere near your base with guards (depending on your area) personally I recommend mammoths and tamed ones. Next take any of your birds and go around on beaches pluck a dodo and bring it back and drop it in. Keep doing this until you can’t find any more. Then make a staircase with wooden ramps up to it up and down. Then make a door and walls and all that at the bottom of it inside the cage. Then you can go in and out without constantly having to get on your bird and worry about things getting in or out other than pteranodon sand other fliers. Argies are really all you need to worry about there. Next because wild animal shit lasts longer you can walk in take their shit and eggs I usually take females because two times the use both food and fertilizer and then boom poop slash fertilizer fiesta for u! U get it.

a cute, simple little bird. they come in slightly different sizes. easy to tame by knocking it out with your fists and feeding it various berries, mejoberries work best. they are pretty much useless unfortunately, so they mostly just make cute little pets. the only thing i guess they can do is carry a little bit of weight for you if you're a beginner, but they're already very slow so that'll just make them really sluggish. they're mostly only good for sitting around and looking cute.
