This has been proven by the fact that hybrid offspring produced by the crossing of nandays with jendays are fertile and do reproduce successfully. Nandays also enjoy emptying nest boxes of material, and an 18-inch depth is recommended. The interior nest box material that is most commonly used for all conures is pine shavings. Although they are still members of the Aratinga genus, they are another step further away from the macaws. At that point, some pairs will only produce a few babies a year, while others will become prolific producers like those of the gold cap group.
Some pairs never produce at all.
This problem is due to the fact that they show a strong reluctance about entering the standard nesting boxes usually provided in captive-breeding setups. In their natural habitats, they excavate arboreal termite nests to make nesting cavities. These large termite nests are made of a material that is similar in consistency to spongy paper-board. The conures will chew a hole in the side of one of these mounds, excavate an internal cavity and lay their eggs. The termites close off all openings that lead from the conures' nesting chambers to the rest of the termite nest.
