Made of FSC™ certified wood, that is sourced from forests that are managed correctly and responsibly according to strict environmental, social and economic standards and other controlles sources, these bird nests are essential for allowing birds to nest in complete tranquillity. They can be fixed to the cage mesh thanks to the internal white iron wire, which must be passed through the rear holes and shaped into hooks. They feature a charming themed decoration on the front and a practical opening lid, useful for making cleaning operations easier. Available in different sizes, they come complete with a perch and a special entrance hole to allow easy access for the bird. Depending on the model, the entrance hole diameter ranges from 5 to 8 cm. The Large and Extra Large nests, for example, are particularly suitable for cockatiels, parakeets and budgies.
