This particular species is found at higher altitudes than other pygmy parrots, and uses trees rather than arboreal termite nests as breeding sites.
They have jerky movements, rather reminiscent of nuthatches (Sitta species), and cling close to the bark as they search for lichens growing in the trees, which form the majority of their diet.
The global population size has not been quantified, but the species is reported to be common to uncommon due to deforestation and habitat lost on this limited range.
It is best to study these birds in their natural habitat because they do not thrive in captivity.
[2] The specific name bruijnii commemorates the Dutch plume merchant Antonie Augustus Bruijn.
