The Rainbow Lorikeet is a nectarivore and the Noisy Miner feeds on both nectar and insects, so it was not surprising that these species frequented the flowering trees.
These were sub-classified into six categories: 1) Forager (F): those insects that fed on pollen without entering the nectar camera (a groove at the base of the style); 2) Nectarivore (N): those that entered the nectar camera to feed and representing specialized pollen collecting behaviors of cactus specialist bees (Schlindwein and Wittmann, 1997); 3) Forager-nectarivore (FN): those who visited the flower to feed on pollen and nectar; 4) Visitors of inner tepals (Ti): those who landed inside the tepals without feeding on pollen or nectar; 5) Florivory on stamens (Fe): those individuals that visited during the flowering process to feed on stamens; 6) Florivory on tepals (Ft): those individuals that were present during the flowering process to feed on tepals.
The species recorded were classified according to their feeding niche, based on Nowak (1994), as insectivore, frugivore, nectarivore or hematophagous.
Across taxa, nectarivore pollinators display many similar behaviors.

In a field experiment on another nectarivore, the bronzy sunbird (Nectarinia kilimensis), Lott and Lott (1992) chose a different set of variables: (1) percent time absent, (2) unchallenged intruders per hour present, (3) challenged intruders per hour present and (4) latency to displacement of challenged intruders.

Such research has been done for several specialist avian nectarivores, and for a few passerine occasional nectarivores, but not, apparently, for any nonpasserine occasional nectarivore.
Nectarivore bats were represented by two species and showed a relative abundance of 10.
According to Koopman (1981), Anoura geoffroyi is a more primitive and more generalized nectarivore than L.
Effects of forest fragmentation on frugivore and nectarivore species have been pointed out in French Guiana (Cossons, 1999).
