Monk Parakeets, also called Quaker Parrots, are native to South America.
Above and immediately below are feral Monk Parakeets that have colonised Tenerife, Canary Islands.
Monk Parakeets also have a small feral colony in the UK.
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.
Above are feral Monk Parakeets in Barcelona, Spain, by the port and by the Sagrada Familia cathedral. They gather pine twigs to construct nests in pine trees.
The bird above centre/right has two beaks! Like a lizard's tail, the parrot's beak will regenerate when broken and sometimes mistakes occur.
