The "drinking straw" is a twig for the nest. Monk Parakeets are the only type of parrot which builds a large nest of twigs, usually on tree branches. Some other parrots take small twigs, leaves or grasses into a nesting cavity for the interior nest but the Monk has an exterior construction of twigs rather than nesting cavity (see below). Sometimes several pairs of families (including a related helper) will nest in the same conglomeration of twigs, with different entrance holes.
