It’s interesting you use the word “pressing” – Does it look hard enough that they might be checking the solidity of the proposed nest & perches & surrounds, for signs of terminal rottenness in the wood? Are there typical tree species they use wherever you are located? If so, are these tree species subject to rottenness at the hollows, &/or insect infestations beneath the surfaces?
Alternatively, is the Eastern Rosella one of the parrots in which couples will rest with their foreheads touching together? If so, this forehead-to-wood thing might be a part of nest-choice ritual never noted before by science…
Proximity to wild-bird nests is such an honour, & so enlightening. Since the work of the Cuppers, really, there’s been little excitement at the richness of such observation – until the intimate world of live nestcams arrived more recently. (Does Forshaw mention this, do you know? – “Australian Parrots” 3rdEd)
Anyway, worth looking at the species throughout its range as the breeding season opens.
