To cut a bird's mouth on a rafter for proper installation, use a framing square to mark the cutout shape on the rafter. Then, use a circular saw to carefully cut along the marked lines to create the bird's mouth notch. This notch will allow the rafter to sit securely on the wall plate for proper installation.
To cut a bird's mouth when constructing a roof truss, use a saw to create a notch in the bottom of the rafter where it meets the top plate of the wall. This notch allows the rafter to sit securely on the wall and provide support for the roof structure.
If the plate height gets higher increase the depth of the birds mouth that sits on the plate. The birds mouth is the notch cut out of the rafter that allows it to sit flat on the top of the plate. If the plate is low then you will need to place a packer on top of the plate.

Birds
It depends how old they are. You need an incubator if they are in eggs still. I've seen people feed baby birds mouth to mouth...Pretty discusting! Leave it to the mummy and daddy birds for best result
Just like us, birds take in air through the nostrils or mouth.
As with most birds, they have no teeth.
The mouth proper refers to the opening of the oral cavity where food and liquids enter the body. It is lined with mucous membranes and contains the teeth and tongue, which help with chewing and swallowing. The mouth proper is a vital part of the digestive system.
Different birds require different beaks and mouth-parts depending on their diet. Birds that eat meat need heavy, powerful beaks, nectar-feeding birds need long, thin beaks, etc. Beaks can also be used to attract a mate.

His mouth is called a 'mouth." But if you mean the combination of his mouth, lips and nose (basically everything below the eyes) then you mean the 'muzzle.'
The earliest birds had toothed beaks. However, toothless birds did evolve and then coexist with toothed birds. The toothed ancestors of birds lived around 150 million years ago.
